Senior Editor<br />


A fresh start<br />

Happy New Year! We hope you all enjoyed the<br />

happy holidays.<br />

As with each of our <strong>January</strong>/<strong>February</strong> issue,<br />

we are kicking off the year with a couple of<br />

interesting stories.<br />

For starters, the United States Government,<br />

in partnership with the Association of<br />

Southeast <strong>Asia</strong>n Nations (ASEAN) and UL,<br />

aim to strengthen ASEAN science and<br />

technology capacity, and gender equality and<br />

improvement through the annual ASEAN-<br />

U.S.Science Prize for Women. And last year’s<br />

winner was Dr Zhou Yan, associate professor<br />

in the School of Civil and Environmental<br />

Engineering (CEE), and deputy director of<br />

Advanced Environmental Biotechnology Centre (AEBC) under Nanyang<br />

Environment and <strong>Water</strong> Research Institute (NEWRI), Nanyang Technological<br />

University, Singapore (p.10). Her win defines an encouragement for women<br />

scientists pursuing their research career in a male-dominated industry,<br />

and we are definitely looking forward to the innovative projects and<br />

achievements that Dr. Zhou will showcase in <strong>2020</strong> and beyond.<br />

In addition, we have Dr Ngoc Lieu Le who is a finalist from the annual<br />

ASEAN-U.S.Science Prize for Women (p.12). Dr Ngoc’s research covers a<br />

wide range of interdisciplinary research fields with a focus on the areas of<br />

energy generation from renewable sources.<br />

We also spoke with Loic Lebegue, global business development director for<br />

the environment industry at ANDRITZ Separation (p.14). He shared with us<br />

on how ANDRITZ adapts to the challenges in Southeast <strong>Asia</strong> while retaining<br />

its status as a powerhouse in the region.<br />

We would also like to draw attention to Pani Energy, which has made a<br />

name for itself through the development of new technologies and its focus<br />

on improving efficiencies in the desalination and industrial wastewater<br />

treatment industries (p.45). In this story, Devesh Bhadradwaj, CEO of<br />

Pani Energy, takes us through how the company makes the most of<br />

artificial intelligence (AI) and machine learning to assist plant operators<br />

beyond cursory data monitoring. A refreshing read for readers who have<br />

found previous industry-changing technologies not delivering on<br />

everything they promised to.<br />

And finally, with a new year and the start of a new issue, you’ll see a<br />

revamped look to our section head columns as well as improved layouts.<br />

We hope this will bring a breath of fresh air and to improve easy reading<br />

for you.<br />

6 THE NEWS<br />

Pan <strong>Asia</strong>n Flow Technology and Muhr Holding Gmbh<br />

form MUHR <strong>Asia</strong><br />

THE 6 th of September 2018 was a<br />

significant date for both Pan <strong>Asia</strong>n<br />

Flow Technology (PAFT) and Muhr<br />

Holding Gmbh: Both companies<br />

entered an agreement to form<br />

MUHR <strong>Asia</strong>, a joint venture company<br />

aimed at manufacturing and<br />

marketing hydro/water applications<br />

and solutions in <strong>Asia</strong>.<br />

Since then, MUHR <strong>Asia</strong> has been<br />

keeping busy, exhibiting in various<br />

water and hydro shows in the<br />

region and allowing the company<br />

to raise brand awareness, venture<br />

into different countries and expand<br />

its sales network into the Southeast<br />

<strong>Asia</strong>n region.<br />

Tan said, “Each of these countries<br />

have a different state of development,<br />

and they have different notions of<br />

how treatment should be like. For<br />

Singapore, PUB is pushing very hard<br />

on reducing sludge, saving energy,<br />

flood mitigation like the Stamford<br />

Diversion Canal, and they’re also<br />

looking into advanced reclamation<br />

to keep out the sea. For different<br />

countries there are different states<br />

of development so it’s not easy to<br />

say where the trend is moving, but<br />

different countries are moving at<br />

different speeds. For example, in the<br />

Philippines, they’re still trying to make<br />

their non-revenue water (NRW) as low<br />

as possible.”<br />

According to General Manager Tan<br />

Wei Hong, MUHR <strong>Asia</strong>’s primary<br />

goal is to address flooding issues<br />

within Southeast <strong>Asia</strong>.<br />

“Flood control, flood mitigation and<br />

flood barriers have been used quite often<br />

in Europe – for cities in Southeast <strong>Asia</strong>,<br />

we’re still quite ill-prepared for that. So far,<br />

hydromechanical products have been used<br />

very often in municipal wastewater plants<br />

and industrial wastewater plants, but to put<br />

it into use for flood control has not been<br />

done so extensively in Southeast <strong>Asia</strong>.<br />

Everyone knows how they’re being<br />

used – for wastewater treatment plants<br />

in municipal regions, for drinking water<br />

treatment, penstocks and stoplogs are used<br />

quite often in the treatment process, to<br />

control the flow in the tanks. These can also<br />

be used for flood mitigation or in cities.”<br />

MUHR <strong>Asia</strong>’s head of Sales Flow Control,<br />

Florian Steiner, further elaborated, “These<br />

are similar products, and we have already<br />

MUHR <strong>Asia</strong>’s General Manager, Tan Wei Hong<br />

dealt with hydromechanical equipment for<br />

a long time – their main purpose is to block<br />

and isolate water. A flood is essentially a<br />

lot of water flow, it has to be isolated and<br />

blocked from buildings and infrastructure<br />

to protect the facilities – that’s the idea<br />

behind it.”<br />

So far, MUHR <strong>Asia</strong><br />

has enjoyed a<br />

positive market<br />

reception towards<br />

their products<br />

and solutions<br />

offered, but Tan<br />

has observed that<br />

Singapore may<br />

not offer the best<br />

solutions in terms<br />

of what might be<br />

feasible for other<br />

ASEAN territories.<br />

MUHR <strong>Asia</strong>’s Head of Sales Flow Control,<br />

Florian Steiner<br />

“Going forward in Southeast <strong>Asia</strong>,<br />

we’re looking to have a more secure<br />

source of water. As you know, secure<br />

water sources are getting lesser, with<br />

depleting sources, and this is one<br />

of the priorities of different water<br />

utilities in Southeast <strong>Asia</strong>.”<br />

Steiner explained, “Singapore’s quite highlydeveloped<br />

in water and wastewater, and<br />

other regions are not as highly-developed.<br />

And there will be a demand in the future<br />

because the people<br />

rely on fresh water,<br />

reliable water, and<br />

of course that’s<br />

coming from the<br />

wastewater. You have<br />

to do something with<br />

the wastewater, you<br />

can de-sludge it, you<br />

cannot just put it in<br />

the rivers and then<br />

complain about it.”<br />

Congratulations on your win! Could you share with us your<br />

thoughts on being the winner of the 2019 ASEAN-U.S. Science<br />

Prize for Women?<br />

Dr ZY I am deeply honoured to be chosen as the final winner. I<br />

am really happy that my research and contributions are<br />

recognised. I shall continue my research in the sustainability and<br />

circular economy area, and produce more impactful and applied<br />

solutions.<br />

What do you think this signifies for women in the water and<br />

wastewater industry?<br />

I hope I can be a good model for the women in the water and<br />

wastewater industry, and encourage women scientists to pursue<br />

their research career in this field.<br />

What are some of the biggest challenges that women who want<br />

to come into the water and wastewater industry will face today?<br />

The biggest challenge could be that people always have doubts<br />

on women’s capability in the engineering field, in general. They<br />

are not confident with our engineering design and the ability of<br />

project execution and delivery. To tackle this, we really need to<br />

prove ourselves with successful track record. It would be very<br />

difficult in the beginning, but we have to try our best.<br />

What would be your message for women coming into this<br />

industry?<br />

Every first entry will be challenging. This is especially more<br />

challenging for women who need to take care of both family and<br />

career. But women definitely have advantages in the environmental<br />

field. We are good at overall project design and planning as well<br />

as are efficient in micro-level management. Do not give up when<br />

you encounter difficulties, it is a part of the learning process. Your<br />

additional effort will eventually pay off.<br />

How did you step into researching for energy efficient water<br />

treatment and reclamation, and resource recovery from sludge<br />

and waste?<br />

It has been too long that people only focus on linear economy.<br />

Huge amount of resources are wasted. In the wastewater<br />

treatment area, intensive energy and chemicals are consumed<br />

during the treatment process. Actually, there are much more<br />

energy and chemicals we can recover from wastewater. So I<br />

decided to move away from wastewater treatment and into water<br />

and resources recovery from wastewater.<br />

How has your background prepared you for your success in the<br />

industry?<br />

I started with fundamental research on the development of energy<br />

efficient wastewater treatment process, and energy recovery<br />

from wastewater and sludge. I had some break-through findings<br />

and novel ideas that are published in top tier journals. However, I<br />

believe the research results should be translated into engineering<br />

application so that the value of the research can be realised.<br />

Hence, I seek support from local funding agencies and my research<br />

institute to scale-up my technologies.<br />

Meanwhile, I am active in philanthropic projects in the ASEAN<br />

region via NEWRIcomm. Through these ways, I’ve gained intensive<br />

engineering experience to deploy the research knowledge into real<br />

application.<br />

What are some of your proudest achievements and how has it<br />

shaped you as a person? Could you also share with us of an interesting<br />

project which you’ve done that has made a huge impact?<br />

I am a member of Lien Foundation - Environmental Fellowship<br />

Program mentor team. I am very proud to be involved in<br />

philanthropic projects; to deploy my research experience and<br />

knowledge into projects in developing countries so as to solve their<br />

water and waste issues.<br />

One of the projects that I am proud of is the project in Kandy, Sri<br />

Lanka. I am one of the key contributors to the design of a wastewater<br />

treatment facility for the Temple of the Tooth and also a team<br />

member in remediating Kandy Lake. Through that project, I started<br />

my collaboration with the University of Peradeniya (UOP) to further<br />

develop anaerobic technologies according to local context.<br />

The project was accorded the IES Prestigious Engineering<br />

Achievement Award and ASEAN Outstanding Engineering<br />

Achievement Award in 2017.<br />

What’s next?<br />

For the next few years, I am looking at valuable products recovery<br />

from wastewater and waste that can potentially transfer a<br />

wastewater treatment plant into a power and chemical production<br />

plants. Chemicals, like cellulose, short-chain and medium-chain<br />

fatty acids, biodegradable plastics — PHA, and nutrients —<br />

fertilisers, can all be produced and recovered at lab-scale, currently.<br />

The challenges in the next phase will be process scale-up and how<br />

to seek interests from the market. WWA<br />

<strong>January</strong> / <strong>February</strong> <strong>2020</strong> • waterwastewaterasia.com


Dr Ngoc Lieu Le is one of the finalists and one of the two women chosen from the water and wastewater industry.<br />

Dr Ngoc Lieu Le<br />

Dr Ngoc Lieu Le is currently a lecturer and faculty member<br />

at the School of Biotechnology at International University,<br />

Vietnam National University HCMC.<br />

Her research covers a wide range of interdisciplinary research<br />

fields with a focus on the areas of energy generation from<br />

renewable sources.<br />

In 2010, Dr. Ngoc was a recipient of IES Prestigious Engineering<br />

Achievement Award from the Institution of Engineering in<br />

Singapore. This is a recognition of an outstanding engineering<br />

project which has made significant contributions to Singapore’s<br />

development. She was also a recipient of the Green Talents<br />

award by the German Federal Ministry of Education and Research<br />

in 2013 for her outstanding achievements in creating a more<br />

sustainable society. In fact, these are only some of the awards<br />

mentioned.<br />

Could you share with us your thoughts about being a finalist for<br />

the Fifth Annual ASEAN-U.S. Science Prize for Women?<br />

DR N I am extremely honoured to be one of the finalists for the<br />

Fifth Annual ASEAN-U.S. Science Prize for Women. I am earnestly<br />

grateful for this recognition for my work on sustainable energy,<br />

water and environment. The recognition is an important impetus<br />

for me to continue pursuing this line of research and to, hopefully,<br />

turn promising research into real solutions. I also hope this<br />

opportunity will create fantastic collaborations with the ASEAN<br />

region’s leading researchers as we further face the complexities<br />

from global issues that individuals cannot tackle alone.<br />

What do you think is the deciding factor that got you picked as<br />

one of the finalists?<br />

I think the committees evaluated my achievements in the circular<br />

economy research, my passion and commitment in the field as<br />

well as my contribution in advancing the role of women in science<br />

by active mentorship, serving as a role model, and my strong<br />

responsibility in many different local, national and international<br />

positions.<br />

<strong>January</strong> / <strong>February</strong> <strong>2020</strong> • waterwastewaterasia.com


What steps do you think should be taken to attract women into<br />

the water and wastewater industry?<br />

I think there are many steps that should be taken to attract<br />

women in the field. For example, we need interventions that<br />

encourage more female students pursuing the Science,<br />

Technology, Engineering and Mathematics (STEM) subjects<br />

because they are the background for those entering into the<br />

technical fields, including the water sector.<br />

Only when women pursue STEM subjects then they have the<br />

chance to love them and enjoy the related fields. Also, the<br />

government should provide funding for water projects in<br />

communities where there is gender-balanced decision making.<br />

Improving gender diversity in funding capacity development<br />

projects can promote a more gender-balanced pool of skilled<br />

professionals for the water sector.<br />

What will be your message for women coming into this industry?<br />

Do not think that we are unable to fulfill the tasks in the water<br />

industry. In recent years, the water sector needs people to work<br />

smart instead of physical labour. The job is innovative, colourful<br />

and rewarding so you will never get bored. <strong>Water</strong> is fundamental<br />

in greening the economy and to transition to social sustainability.<br />

Working in this field means we are making our lives and society<br />

better.<br />

How did you step into researching for wastewater treatment to<br />

be recycled and/or to reduce environmental impacts?<br />

When I studied my PhD at the National University of Singapore, I<br />

was fortunate to work in Professor Neal Chung’s group, one of the<br />

leading groups in membrane science and technology for energy<br />

and water application. Working in a big research group gave me an<br />

eye-opening mindset in research, realised the need for individual<br />

contribution in tackling social-economic issues and understand<br />

how, we, as scientists can do much more to make lives better.<br />

Since then, the water sector has become one of my main research<br />

focuses.<br />

Could you share with us an interesting project which you’ve<br />

done that has made a huge impact?<br />

In Vietnam, one of reasons for water pollution is that thousands<br />

of small enterprises engaged in textile dyeing in local villages<br />

or provinces, and discharged untreated wastewater into the<br />

Red River Delta and Mekong Delta, the two main river systems<br />

in Vietnam. So, we developed the membrane-based separation<br />

system to completely remove and recover numerous types of dye<br />

from the effluent before discharge. Besides dyes, the system also<br />

removes other pollutants such as salts or organics.<br />

Another interesting project is the collaboration with the University<br />

of Edinburgh, UK. It is the development of a low-cost water<br />

purification technology that can upcycle pollutants in order to<br />

provide clean water supply for shrimp farms, an important<br />

business in Vietnam which provides a livelihood for more than one<br />

million people. The project is ongoing and I believe it will make a<br />

huge impact when completed.<br />

What is the greatest transformation you’ve witnessed in your<br />

career?<br />

After my PhD completion, I worked for 3.5 years as a postdoctoral<br />

fellow in Saudi Arabia until 2017. I then went back to Vietnam to<br />

work at the International University as a faculty member. This is<br />

the greatest transformation in my career as it shaped me into an<br />

independent scientist. Scientific independence is important for a<br />

scientist as this means that I have the freedom to develop my<br />

own research ideas, conduct research for the social-economic<br />

problems I wish to tackle, seek funds to support my research and<br />

build my own research team.<br />

What is next for you?<br />

We live in a technological world, and its complexity continues to<br />

throw out challenges that require answers. <strong>Water</strong>, for example, is a<br />

complex issue that requires a wider research scope with multidisciplines<br />

to recognise the wider considerations and generate<br />

more creativity to overcome barriers. For me, in order to do so, I<br />

empower myself with great energisation, motivation and passion<br />

in connecting, collaborating and creating collaborative research<br />

with various partners including local and foreign scientists,<br />

enterprise, decision-makers and policy-makers. This is to achieve<br />

a better and more sustainable world. WWA<br />

Southeast <strong>Asia</strong> (SEA) is an active and fast-evolving region.<br />

Consequently, the growing population, urbanisation and rising energy<br />

demands have brought about significant challenges when it comes<br />

to efficiency in wastewater treatment, sludge treatment, or providing<br />

drinking water as well as from seawater desalination. In addition,<br />

environmental regulations constantly add new pressures while the<br />

conservation of energy and resources remains a top priority. ANDRITZ<br />

shares how they tackle these challenges while retaining their position<br />

as a powerhouse in this region.<br />

Loic Lebegue,<br />

Business Development Manager for the<br />

Environment Industry at ANDRITZ Separation<br />

The ANDRITZ organisation in the<br />

region, which is both <strong>Asia</strong> Pacific<br />

based and led, is supported by the<br />

global team of separation professionals,<br />

their experience, and financial strength,<br />

geared towards delivering efficient,<br />

sustainable, reliable, and safe wastewater<br />

treatment solutions that will meet even<br />

the most stringent local requirements,<br />

explained Loic Lebegue, global business<br />

development director for the environment<br />

industry at ANDIRTZ Separation.<br />

For more than 150 years, the<br />

organisation has been delivering smart<br />

separation solutions, and today, it<br />

covers the entire wastewater and sludge<br />

treatment process — from screening and<br />

thickening to dewatering, drying, and<br />

combustion.<br />

“We believe that the treatment of<br />

industrial wastewater streams is becoming<br />

a hot topic. From pulp and paper to food<br />

processing or chemical industries, the<br />

industrial output is growing across the<br />

region, requiring closer attention to waste<br />

and wastewater treatment,” said Lebegue.<br />

In order to tackle complex challenges<br />

brought forth by the growth, a trusted<br />

and reliable partner such as ANDRITZ is<br />

required. Lebegue also emphasised that<br />

the most important factor is to continue to<br />

invest in wastewater treatment facilities.<br />

But just as regulatory standards are being<br />

tightened up, municipal budgets are also<br />

coming under more pressure. However,<br />

ANDRITZ believes that with its full and<br />

global view of the wastewater treatment<br />

needs, the organisation is able to act as a<br />

trusted, long-term partner.<br />

ANDRITZ decanter centrifuge D for efficient thickening and dewatering<br />


A fast-growing middle class with<br />

rising incomes coupled with a young<br />

population in most SEA countries, there<br />

is an increased demand for high-quality<br />

food and drinks, safe water provision,<br />

and increased standards of living. This<br />

triggers growth in all related industries,<br />

such as food and beverages, chemicals<br />

and pharmaceuticals, as well as the<br />

environmental industry with its focus on<br />

sustainability. In those important sectors,<br />

efficient separation processes are vital for<br />

improving products while reducing waste.<br />

“And on the municipal side: populations<br />

across the SEA region are expecting<br />

and demanding better living standards,<br />

and this requires extensive wastewater<br />

collection and sustainable treatment,” said<br />

Lebegue.<br />

So, exactly how does ANDRITZ resolve the<br />

separation challenges with their expertise?<br />

“You should ask our customers!” joked<br />

Lebegue. “Jokes aside, we believe that our<br />

approach as defined in our motto “Ask<br />

your Separation Specialist” is what we<br />

are doing well: Ensuring that our customers<br />

get the ideal solution. In particular in<br />

wastewater treatment, we have maybe the<br />

most comprehensive portfolio in the industry<br />

for the key process steps; this enables us to<br />

provide the right solution for each specific<br />

plant.<br />

Take sludge dewatering, for instance.<br />

Here, we offer screw presses, belt presses,<br />

centrifuges, or filter presses. We know that<br />

there is not just one solution that is always<br />

the best choice for operators — no “one size<br />

fits all”. We are keen to engage this discussion<br />

with our customers and establish with them<br />

the best choice of technology based on their<br />

key performance criteria and indicators.”<br />

This is true for dewatering equipment but<br />

also highly relevant for complex systems such<br />

as sludge drying systems where ANDRITZ<br />

delivers all four existing technologies: Belt,<br />

drum, paddle and fluid bed.<br />

In addition, the organisation also focuses<br />

on the area of machine and process control<br />

where they apply innovative automation<br />

solutions, and IIoT technologies to further<br />

optimise their high-end products and<br />

systems in terms of efficiency, energy<br />

consumption, reliability, and sustainability.<br />

A recent example of digitalisation in<br />

the wastewater industry is ANDRITZ’s<br />

intelligent filter press. ANDRITZ combined<br />

its proven filter press automation<br />

solutions with the Industrial Internet of<br />

Things (IIoT) technologies to create new<br />

mechanisms and features that increase<br />

product quality and decrease operating<br />

costs. These features such as monitoring<br />

of dry solids content and filtrate quality<br />

allow, for example, intelligent washing<br />

cycles. A filter-press is a batch-operated<br />

machine and, often, the filtration cycles<br />

are simply bound to a specific time period.<br />

With ANDRITZ’s intelligent filter press,<br />

the equipped Smart Sensors ensure that<br />

filtration and wash cycles are just as<br />

long as they need to be, thus, reducing<br />

fluctuations in the dry solids content and<br />

increasing up-time availability of the filter<br />

press as well as end-product quality.<br />

Another proof to ANDRITZ’s strength is<br />

their contribution to one of the world’s<br />

largest wastewater treatment plants in<br />

Bailonggang, Shanghai, China.<br />

<strong>January</strong> / <strong>February</strong> <strong>2020</strong> • waterwastewaterasia.com

16 5 MINUTES WITH<br />

The company provided the complete sludge<br />

drying and incineration system comprising<br />

sludge storage, drying, incineration, and<br />

flue gas cleaning as well as automation for<br />

the entire plant. The design of this solution<br />

was developed over many years while<br />

working closely together with the Shanghai<br />

municipality and its consultants.<br />

“We possibly could also have offered<br />

another drying technology in a similar<br />

system, but at the end it is our “Ask your<br />

Separation Specialist” approach which gave<br />

the opportunity to the end-user to make<br />

sure his concerns were addressed. Together<br />

with him, we engineered this special system<br />

combining fluid bed technology for drying<br />

and incinerating the sludge. That’s what<br />

makes us different,” Lebegue explained.<br />

Currently, commissioning is on-going. Once<br />

completed, the plant will have a capacity<br />

of up to 3,000 metric tons of sludge a<br />

day and will be the world’s largest sludge<br />

incineration plant — a benchmark among<br />

China’s environment projects.<br />


In Singapore, ANDRITZ has long had a<br />

presence through its brands such as Bird,<br />

KHD Humboldt, and Netzsch Filtration.<br />

ANDRITZ has built on this existing<br />

infrastructure over the years to develop<br />

and expand its local capabilities to service<br />

customers as effectively as possible in this<br />

growing region.<br />

Since the first commissioning at Kranji<br />

in 1996, ANDRITZ has been providing<br />

emergency service, performing monthly<br />

preventive maintenance, supplying spare<br />

parts, and complete overhauls for their<br />

large installed base, which has been<br />

growing over the years in Singapore and<br />

across the region.<br />

“We want to serve our customers even<br />

better, so we made a significant investment<br />

in the ANDRITZ Singapore Tuas workshop<br />

and repair facilities in 2018. These<br />

upgrades have set us apart as a regional<br />

service center. They not only demonstrate<br />

our commitment to Singapore and our<br />

passion for continuous improvement,<br />

but also reflect our determination to<br />

deliver the best possible service and<br />

support ANDRITZ can provide and that<br />

our customers expect. Our ANDRITZ Tuas<br />

service center is therefore a strong base<br />

for all our SEA business,” said Lebegue.<br />

The major investment saw a state-of-theart<br />

high-speed balancing facility with a<br />

balancing machine of 4,000 rpm, with<br />

six-ton capacity, six-metre working length,<br />

and two-metre diameter. This balancing<br />

“bunker” allows the balancing of decanter<br />

centrifuge parts, including scroll conveyors,<br />

at their normal operating speed while<br />

ensuring optimal performance after the<br />

repair and reduces on-site downtime with<br />

“no surprises”, re-assembly, and re-start.<br />

This comes in addition to their specific<br />

services such as gearbox reconditioning,<br />

welding of tungsten carbide tiles for wear<br />

protection, or their environmentally friendly<br />

blasting process utilising dry ice.<br />

“Our service philosophy is simple. One<br />

phone call, one dedicated team that speaks<br />

our customers’ language and knows their<br />

equipment and process. Therefore, whether<br />

our customers are looking to optimise or<br />

extend the lifetime of their equipment,<br />

our team can troubleshoot and perform<br />

maintenance on our customers’ machines<br />

on-site or repair, retrofit, and modify them<br />

in our modern decanter service workshop,<br />

24/7,” said Lebegue. WWA<br />

The infrastructure engineering for digital cities<br />

At the Year in Infrastructure 2019<br />

Conference, Bentley Systems,<br />

Incorporated, the global provider<br />

of comprehensive software and digital<br />

twin cloud services for advancing<br />

design, construction, and operations of<br />

infrastructure, presented its new digital<br />

cities initiatives; applying digital twins for<br />

more efficient city and regional operations,<br />

and for more connected and resilient<br />

infrastructure. Digital twins converge<br />

assets’ 4D-surveyed and engineering<br />

representations to enable new collaborative<br />

digital workflows to serve planners and<br />

engineers in public works, utilities, property<br />

management and development, and city<br />

stakeholders. Digital twin cloud services<br />

provide an intuitive and immersive 4D<br />

environment converging digital context and<br />

digital components with digital chronology<br />

for “evergreen” infrastructure digital twins<br />

over asset lifecycles. For infrastructure<br />

professionals, BIM and GIS are effectively<br />

advanced through 4D digital twins.<br />

“The concept with digital twin is a digital<br />

representation of some real-world assets,<br />

systems or processes. But because we<br />

have a digital mirror of that, that becomes<br />

something we can keep up to date to reflect<br />

the real-world behaviour. We can do things<br />

with the digital twin before translating<br />

them to the real world,” explained Gregg<br />

Herrin, senior director, <strong>Water</strong> Infrastructure,<br />

Bentley Systems. “So, we can use that to<br />

help us understand how to work things<br />

better and make decisions about possible<br />

actions that we would take.”<br />



City-scale digital twins begin and are<br />

updated through 4D surveying and reality<br />

modelling by ContextCapture and Orbit<br />

GT, which Bentley recently acquired,<br />

to derive as-operated 3D models from<br />

photogrammetry (including from UAVs)<br />

and/or point clouds. Reality modelling<br />

provides engineering-precise, realworld<br />

context to support planning,<br />

design, construction, and operations.<br />

Users of Bentley’s open applications<br />

(OpenBuildings, OpenSite, OpenRoads,<br />

OpenRail, OpenUtilities) can leverage this<br />

digital context to model new and improved<br />

buildings, roads, transit systems, tunnels,<br />

bridges, utilities, and more.<br />

4D digital twins become a common<br />

and federating index for previously<br />

siloed information, without requiring<br />

source systems to change their existing<br />

environments or data formats. The<br />

foundation context for any digital twin<br />

includes reality meshes, terrain models,<br />

imagery, and GIS sources. Engineering<br />

models (from any BIM software) of<br />

buildings, streets, transit systems, utilities,<br />

and other city infrastructure, both surface<br />

and subsurface, are semantically aligned<br />

and geo-referenced to enhance the richness<br />

and relevance of digital twins over time.<br />

Public works departments, property<br />

developers, utilities, transportation<br />

agencies, and others now have access to a<br />

full and current contextual view of the built<br />

environment. Engineering and architectural<br />

firms will be able to develop new services<br />

that contemplate updating and managing<br />

digital assets over their lifecycles. Cities<br />

will also benefit from living and current<br />

digital twins of their infrastructure and<br />

surrounding environment.<br />



Most of the utilities or cities already have<br />

some kind of GIS data or data collection<br />

system or have a plan to get it, said Herrin.<br />

He explained, “The truth is you can have<br />

nothing but an old CAD drawing and a<br />

general sense where some things are<br />

from the spreadsheet. You may not have a<br />

precise digital twin but you can always start<br />

there and use it to help you understand<br />

what you can and can’t see within your<br />

system.”<br />

“Once you have it, you’ll start playing<br />

with it then you want to enhance it. It’s<br />

automatic,” said Frank Braunschweig,<br />

senior product manager, Bentley Systems.<br />

With an older digital twin version, operators<br />

are able to fill in the gaps themselves as<br />

they use it, Braunschweig explained.<br />

“You’re able to take the information from<br />

the real world and instantly get it into your<br />

twin. The twin gets more and more accurate<br />

over time, and more and more precise over<br />

time. It becomes even more useful with<br />

every new piece of information you learn,”<br />

said Herrin.<br />


Águas do Porto (Oporto <strong>Water</strong> Utility - AdP)<br />

is responsible for the sustainable and<br />

integrated management of the entire urban<br />

water cycle in the coastal community of<br />

Oporto, Portugal. AdP delivers an average<br />

of 45,490 cubic metres of water daily and<br />

collects approximately the same amount<br />

for treatment. The density and complexity<br />

of the hydraulic infrastructure and water<br />

resources in Oporto drive the need for<br />

integrated management of the urban water<br />

cycle, which can complicate the integration<br />

requirements for the varied existing<br />

systems throughout the company.<br />

To integrate information across multiple<br />

software systems, AdP decided to leverage<br />

on digital twins in what they called the<br />

Integrated <strong>Water</strong> Management of the Urban<br />

<strong>Water</strong> Cycle – H2Porto. The overall solution<br />

integrated multiple systems, including<br />

Server. The team produced fully integrated<br />

digital twins of the city water supply and the<br />

wastewater, stormwater, as well as beaches<br />

and bathing water systems. The digital twins<br />

were then used to forecast flooding and<br />

water quality issues, improve city services<br />

and responsiveness, and ensure resilience<br />

of water infrastructure.<br />

Phase 1 of the project saw the creation of a<br />

federated environment from more than 20<br />

sources to integrate data from customer<br />

service management, billing, maintenance,<br />

project management, asset accounting,<br />

operational systems, lab management, GIS,<br />

SCADA, and more. Instrumentation data<br />

integration, which was addressed in phase<br />

II, required integrating data from sensors,<br />

telemetry, and remote management,<br />

including 30,000 telemetry meters and<br />

more than 200 devices.<br />

The digital twins provide digital<br />

representations of all water systems of<br />

the city and include three meteorological<br />

models: Combined sewer and storm models<br />

for the sea front; estuary, coastal area,<br />

and wave models; and forecasting models.<br />

The digital twins are leveraged to provide<br />

access to this information in real time,<br />

produce forecasts and to automatically<br />

update boundary conditions from water<br />

consumption and network sensors, run<br />

network scenario analysis for pipe bursts<br />

and valve and pump shut-downs, and<br />

to publish flows, velocity, water level,<br />

meteorology and currents. This digital twin<br />

environment resulted in operating gains of<br />

25% and reduced water supply failures by<br />

around 30% and duration of pipe bursts<br />

repairs by 8%. The immediacy of sensor<br />

readings improved decision-making as well<br />

as increased stability and reliability of data<br />

to about 99%.<br />

Phase III is underway and is focused on<br />

installing sensors and automating the<br />

decision-making tools and interfaces,<br />

autonomous systems and new liability<br />

models. Some of H2Porto’s priorities include<br />

sensor analysis, water supply model, burst<br />

simulation, meter operational management,<br />

and KPIs, as well as hydrodynamic model,<br />

faecal coliform prediction, and coastal<br />

hydrometeorology.<br />

“At the end of the day, the purpose of the<br />

utility has nothing to do with data and<br />

software. The purpose of the utility is to<br />

deliver clean water to the people and take<br />

away dirty water,” said Herrin.<br />

“But what more people are realising is that<br />

we might have gotten caught up in data,<br />

and pretty graphs and charts, but if it’s<br />

not helping us to deliver clean water and<br />

take away dirty water, we’re still missing<br />

something. It’s more than just a data centric<br />

effort to being an actual digital twin, which<br />

again isn’t just the data; it’s the behaviour,<br />

it’s the performance. Now, you get something<br />

that helps you do the real job,” he added. WWA<br />

Singapore International <strong>Water</strong> Week (SIWW) is widely recognised<br />

as one of the leading water events in the world, and is highly<br />

relevant to the urban water environment, placing emphasis on<br />

solutions, innovation and technology.<br />

Set to run from 5-9 July, the show will see its ninth edition.<br />

<strong>Water</strong> & <strong>Wastewater</strong> <strong>Asia</strong> speaks to SIWW’s Managing Director,<br />

Since taking over as the SIWW’s new<br />

managing director, Ryan Yuen has<br />

been keeping busy with planning<br />

and preparing for the upcoming Singapore<br />

International <strong>Water</strong> Week (SIWW), which<br />

will be held at the Sands Expo & Convention<br />

Centre.<br />

Previously, Yuen worked as an engineer with<br />

the Ministry of Environment after graduating<br />

from the National University of Singapore<br />

(NUS), before being posted to work for the<br />

PUB, Singapore’s national water agency.<br />

In 2007, he also served as the International<br />

<strong>Water</strong> Association’s (IWA) regional director<br />

for <strong>Asia</strong>, and engaged top global water<br />

leaders and experts in deploying water and<br />

sanitation programmes and activities around<br />

the region – a period of time he describes as<br />

“truly fulfilling”.<br />

According to Yuen, “Climate change is<br />

the single greatest threat to humanity in<br />

modern times, and the impact of climate<br />

change on urban water systems cannot be<br />

underestimated. We will be examining how<br />

cities, utilities and industries manage water<br />

stresses by mitigating and adapting to climate<br />

change during SIWW <strong>2020</strong>.”<br />

“An effective approach to build resource<br />

resilience would be to embrace the concept<br />

of a circular economy, and proliferate the<br />

recovery and reuse of precious resources like<br />

water, energy and nutrients. In SIWW <strong>2020</strong>,<br />

we will present case studies of how this has<br />

been successfully implemented in different<br />

parts of the world.<br />

The previous SIWW, held in 2018, drew in<br />

over 24,000 visitors from 110 countries,<br />

and over 1100 exhibiting companies. For<br />

this year’s edition, Yuen and his team aim<br />

to build upon that success and bring more<br />

partners, sponsors, delegates, exhibitors<br />

and trade visitors in.<br />

“In doing so, we hope the international<br />

water community will recognise SIWW<br />

as the premier water event for thought<br />

leadership where experts, ministers,<br />

government officials, business CEOs<br />

and civil society leaders come together<br />

to share and discuss the latest policy,<br />

business and technological insights<br />

in tackling our shared urban water<br />

challenges,” he said.<br />

Exhibitors will be showcasing the latest<br />

products, solutions and technologies they<br />

have to offer, and with 14 country pavilions<br />

this year, delegates and visitors will be<br />

spoilt for choice as they visit SIWW.<br />

“We want to ensure that our exhibitors are<br />

able to reach out to their target audience,<br />

especially to buyers from the region,<br />

through SIWW,” explained Yuen.<br />

To do this, SIWW will be introducing<br />

a Hosted Overseas Visitor Programme<br />

and a Hosted Distributor Programme,<br />

in a bid to incentivise overseas buyers<br />

and distributors to meet exhibitors and<br />

establish new partnerships.<br />

Through its B2B business-matching app,<br />

exhibitors will also be able to set up<br />

one-to-one appointments with delegates.<br />

Lastly, a presentation stage will be set up<br />

on the expo floor, providing a platform<br />

for exhibitors to share their products and<br />

innovations with trade visitors.<br />

After working hard, SIWW participants<br />

will have the chance to kick back with the<br />

<strong>Asia</strong> Pacific Breweries (APB) Singapore is part of The HEINEKEN<br />

Company and the home of the world-acclaimed Tiger Beer — a<br />

Singapore icon born and brewed on local soil since 1932. Today, the<br />

company’s portfolio encompasses ABC Stout, Anchor Beer, Baron’s Strong<br />

Brew, Guinness, Heineken and the range of Archipelago craft beers. This<br />

is in addition to internationally renowned beers such as Bulmers, Erdinger,<br />

Guinness Draught, Kilkenny, Kirin, Sol and Strongbow.<br />

As a beer producer, APB Singapore’s operations depend on constant water<br />

supply, which may be exposed to the risk of water scarcity.<br />

Increasing water efficiency and<br />

improving water circularity are<br />

the key priorities to protect and<br />

conserve water resource. As part of<br />

APB Singapore’s water conservation<br />

strategy, the company went into a<br />

joint development project with PUB<br />

and National University of Singapore<br />

to build a water reuse treatment plant<br />

so as to further reduce water usage in<br />

the brewery.<br />

“<strong>Water</strong> is critical for a business like ours as we use water for brewing and nonbrewing<br />

purposes alike. For every 1hl (hectolitre) of beer that we brew, we use<br />

4.6hl of water. And with beer being 95% water, we need to optimise the ways<br />

in which we brew beer to maximise water efficiency, as well as the operations<br />

surrounding it,” said Patricia Lee, corporate affairs director, APB Singapore.<br />

As the largest commercial brewery in Singapore, APB Singapore is committed<br />

to using water wisely, and constantly seek new and innovative ways to achieve<br />

water efficiency. However, it is not an easy task as it takes time, resources, and<br />

multi-stakeholder collaboration.<br />

And so, as part of their commitment to protect water resources,<br />

APB Singapore entered a joint development project with the Public<br />

Utilities Board (PUB), Singapore’s national water agency, and the<br />

National University of Singapore (NUS) in 2017 to develop a solution<br />

to reduce water intake in the brewery.<br />

The joint development project saw the construction of the water<br />

reuse treatment plant by Witco Envirotech Pte Ltd. The plant is<br />

located within APB Singapore’s brewery and cost about<br />

S$1.8 million to build.<br />

In 2019, the water reuse treatment plant became operational. By<br />

treating and reusing the wastewater from the brewery, the plant is<br />

set to reduce the brewery’s water intake by more than 10%, saving<br />

about 66,750m 3 of water annually. The volume of water reused<br />

annually is also equivalent to 3,160 four-room HDB (Housing &<br />

Development Board, the statutory board of the Ministry of National<br />

Development responsible for public housing in Singapore) flats, or<br />

26 Olympic-sized swimming pool. In fact, the treated water, along<br />

with rainwater collected from the rainwater harvesting system are<br />

used for cooling towers, general cleaning and landscaping.<br />

“The water reuse treatment plant uses biological and membrane<br />

processes, including reverse osmosis [by Hydranautics]. Reverse<br />

osmosis is also the process that PUB uses to produce NE<strong>Water</strong><br />

to promote water circularity and address the nation’s agenda of<br />

protecting water resources,” said Lee.<br />

From image 1 to 3: As the largest commercial brewery in Singapore, APB Singapore<br />

is committed to using water wisely, and constantly seek new and innovative ways to<br />

achieve water efficiency. However, it is not an easy task as it takes time, resources, and<br />

multi-stakeholder collaboration<br />

also part of the company’s sustainability agenda. The water reuse<br />

treatment plant runs on energy efficient equipment such as ie3<br />

motors to reduce energy consumption. To top it off, APB Singapore<br />

is also looking to equip their present air blowers, which use the<br />

most amount of energy in the plant, to variable speed drives so as to<br />

optimise the aeration process and to consume less electricity.<br />

“We are one of the first in <strong>Asia</strong> to integrate a water recycling plant<br />

at the premise of operation. We will continue to strategise and seek<br />

innovative ideas, develop capabilities and secure a sustainable<br />

supply of water for our brewery,” Lee said. WWA<br />

The Keppel Marina East Desalination Plant is due to be completed in<br />

<strong>2020</strong> – what sets the dual-mode desalination plant apart from the<br />

others is its complicated design. <strong>Water</strong> & <strong>Wastewater</strong><br />

<strong>Asia</strong> sits with Bentley Systems to find out<br />

how the company’s range of digital<br />

solutions were just what the<br />

facility needed.<br />

Slated for completion in <strong>2020</strong>, the<br />

Keppel Marina East Desalination<br />

Plant (KMEDP) is a large-scale, dual<br />

mode desalination plant that can treat either<br />

saltwater from the sea or freshwater from<br />

the Marina Reservoir. Mostly underground,<br />

the facility features 20,000 square metres of<br />

parkland on the roof and an unconventional<br />

architectural design. The project team<br />

from AECOM Singapore Pte Ltd and Keppel<br />

Seghers used Bentley applications to enable<br />

BIM strategies throughout design and<br />

construction. A digital twin of KMEDP is also<br />

under development.<br />

According to AECOM Singapore and Keppel<br />

Seghers, what makes the KMEDP unique is<br />

how it requires an extensive piping design<br />

– this in turn was a factor towards choosing<br />

Bentley Systems for the plant.<br />

“Bentley Systems is a comprehensive<br />

integrated model that enhances collaboration<br />

among suppliers, contractors and designers<br />

by allowing them to visualise their plans<br />

via 3D modelling, using the full spectrum<br />

of functions available in the software. For a<br />

project like KMEDP which involves multiple<br />

components, it is extremely critical that<br />

engineers are able to fully visualise all<br />

plans in order to resolve conflicts, avoid<br />

abortive works at construction stage, and<br />

collect design data which can eventually<br />

be used to support the operations and<br />

maintenance of the plant,” said Dr Chiu<br />

Kuang Ping, executive director, <strong>Water</strong> &<br />

Urban Development, AECOM Singapore.<br />

For the KMEDP, AECOM Singapore and<br />

Keppel Seghers deployed OpenPlant,<br />

OpenPlant PID, MicroStation, Navigator,<br />

LumenRT and ContextCapture – this<br />

allowed the team to create a 3D reality<br />

model for the KMEDP project, optimising<br />

plant design and construction.<br />

“The OpenPlant allows for more efficient<br />

detailed piping design and this is<br />

particularly helpful because changing<br />

and updating the plant design occurs<br />

regularly during the detailed design stage,<br />

and changes are reflected immediately<br />

and efficiently with OpenPlant. LumenRT,<br />

on the other hand, allows for better<br />

visualisation of the plant,” said Dr Chiu.<br />

According to Keppel Seghers, the solutions have<br />

improved productivity and efficiency of the design<br />

stage for the KMEDP. While static 2D designs<br />

would not have been able to quickly or efficiently<br />

capture the impact of updates and changes, the<br />

3D reality model created with Bentley Systems<br />

helped to reduce the possibility of onsite clashes<br />

and errors.<br />

The KMEDP is currently under testing and<br />

commissioning, and is slated to be ready for<br />

operation in early <strong>2020</strong>.<br />

The plant was recently nominated as a finalist for<br />

the Bentley Systems’ Year in Infrastructure 2019<br />

Awards programme, which honours the work of<br />

Bentley software users advancing infrastructure<br />

design, construction, and operations throughout<br />

The Saras Refinery and Sarlux Power Plant needed to update their shared ultra-pure water plant, which<br />

produced 24,000 m³/day<br />

In Sarroch, on the southern coast<br />

of Sardinia, lies the Mediterranean’s<br />

largest ultra-pure water plant. Built<br />

by ACCIONA Agua in just six months,<br />

the containerised two-pass SWRO<br />

plant provides demineralised water<br />

for the steam needed to drive Sarlux<br />

Power Plant’s turbines and keep<br />

the Saras Refinery in operation.<br />

With Danfoss compact APP pumps,<br />

iSave ERDs, VFDs, and pressure<br />

transmitters, it enabled operators<br />

to save an impressive 88% in energy<br />

consumption as compared to the old<br />

distillation system.<br />

The Saras Refinery and Sarlux Power<br />

Plant needed to update their shared<br />

ultra-pure water plant, which produced<br />

24,000 m³/day. Not only did the aging<br />

distillation plant depend on a combination<br />

of SWRO and surface sources on waterstarved<br />

Sardinia, its energy consumption was<br />

massive. And while electricity might be “free”<br />

for a power plant, the outsized energy bill<br />

represented a significant opportunity cost in<br />

lost sales revenue — not to mention a heavy<br />

carbon footprint.<br />


And so, the plant was looking to provide<br />

12,000 m³/day of ultra-pure water and<br />

reduce its energy costs — fast. In fact,<br />

the refinery and power plant procurement<br />

departments put out a clear but demanding<br />

request for proposals: develop an ultrapure<br />

SWRO solution that would provide half<br />

their requirement —12,000 m³/day, and<br />

significantly reduce energy consumption.<br />

And do it all fast, with minimal capital<br />

expenditure.<br />

ACCIONA Agua’s engineers were familiar with<br />

Danfoss technology, and quickly determined<br />

that Danfoss APP pumps, iSave ERDs,<br />

pressure transmitters, and VFDs could be<br />

part of a winning bid.<br />

The solution was a containerised, four-train<br />

plant, built around compact Danfoss pumps<br />

and ERDs, that could be installed quickly and<br />

without infrastructural modifications.<br />

<strong>January</strong> / <strong>February</strong> <strong>2020</strong> • waterwastewaterasia.com

26 IN THE FIELD<br />

Containerisation was a key element of the winning bid. Not only<br />

could this save time and the construction costs of a new building<br />

to house the plant, it also did away with the need to build new<br />

seawalls, which would otherwise be necessary due to the plant’s<br />

location right on the shore.<br />

But containerisation demanded compactness for all components.<br />

As Pietro Tota, D&C manager at ACCIONA Agua explained, “Danfoss<br />

high-pressure pumps enable us to create systems that are not only<br />

energy-efficient but also extremely compact and can be placed in a<br />

container. Thanks to their small size and simplified internal design,<br />

they can be installed even when space is limited.<br />

1<br />

Just as importantly, they require very little periodic maintenance.<br />

iSave ERDs devices, which drastically reduce energy consumption,<br />

are also extremely compact and are easily integrated with Danfoss<br />

high-pressure pumps.”<br />


ACCIONA Agua’s winning build-and-operate bid consisted of four<br />

ultra-pure SWRO trains in a total of four containers. In all, the<br />

plant uses nine APP 86 pumps and 13 iSave 70 ERDs — as well<br />

as Danfoss pressure transmitters and VFDs for all high-pressure<br />

pumps, pretreatment pumps, and energy recovery devices.<br />

From idea to reality, in just six months, there was an 88% reduction<br />

in energy consumption, and easy maintenance.<br />

The new SWRO plant reduced Sarlux’s energy costs by a remarkable<br />

88%, from about 20 KwH m³ to 2.4.<br />

2<br />

And while this reduced energy bill and carbon footprint, which were<br />

projected by ACCIONA Agua’s engineers, the ease of maintaining<br />

such a large plant went beyond their initial expectations.<br />

“The extreme ease with which high-pressure pumps can be<br />

maintained is one of the most valuable features of Danfoss<br />

technology,” confirmed Tota.<br />

“Unlike traditional centrifugal pumps, which typically need to<br />

be shipped to an authorised workshop for maintenance, we can<br />

perform the maintenance of Danfoss volumetric high-pressure<br />

pumps directly in Sarroch within a couple of hours, with an obvious<br />

benefit in terms of plant availability.”<br />

“We have great confidence in the technological partners chosen<br />

for the construction of the Sarlux modular desalination plant, the<br />

largest in the Mediterranean,” Tota concluded.<br />

“We have come up with an innovative solution based on Danfoss’s<br />

advanced technologies, and this has enabled us to achieve success<br />

and the full satisfaction of our end customer. WWA<br />

Whether solving society’s challenges such as water scarcity, access to drinking water, protecting water<br />

resources, or reducing its water footprint, Royal HaskoningDHV provides technological solutions that<br />

meet these challenges.<br />

With Royal HaskoningDHV’s digital innovation, Aquasuite ® , a software built with deep domain knowledge,<br />

utilities and industry are able to automate their operations and gain actionable insights on their water<br />

infrastructure.<br />

Aquasuite ® is a proven smart<br />

water technology that monitors,<br />

analyses, visualises and controls<br />

the performance of water and wastewater<br />

infrastructure through predictive analytics<br />

and machine learning. Its AI-powered<br />

analytics and autopilot provide full real-time<br />

visibility across the complete water and<br />

wastewater network and treatment, and<br />

controls day-to-day operations.<br />

Aquasuite ® consists of five products, each<br />

addressing a different challenge in the<br />

drinking water and wastewater process.<br />

Aquasuite PURE collects real-time data<br />

on the plant’s flows and qualitative<br />

measurements, including those for<br />

ammonia, nitrates, oxygen, phosphates and<br />

dry solids. The system uses this information<br />

to build a historical database. It will then<br />

make use of algorithms to predict the<br />

plant’s wastewater flows and loads, oxygen<br />

needs, chemical dosing needs and other<br />

requirements. The system can also detect<br />

abnormalities in the plant’s processes and<br />

is capable of controlling key treatment<br />

processes, automatically optimising them<br />

in real-time based on its predictions and<br />

the plant’s historical performance data.<br />

This will result in predictive rather than<br />

reactive control of the plant. This leads to<br />

more stable and robust operations, better<br />

effluent quality, lower energy and chemical<br />

consumption and help enhance operators’<br />

productivity.<br />

installed at the Ulu Pandan Integrated Validation Plant (IVP), and<br />

preliminary results of the project have shown that Aquasuite ® is well<br />

capable of predicting the load entering the treatment plant, learning<br />

its operational performance and controlling treatment processes as<br />

it has successfully taken over control for the past few months.<br />

Prediction accuracy increases over time as the software is learning,<br />

now already reaching a prediction accuracy of 88%. While Aquasuite<br />

is controlling key treatment processes such as aeration, it learns<br />

how the process performs. It is automatically shifting control from<br />

reactive to predicted control set-points, making it less sensitive<br />

to e.g. measurement failure as it predicts control with a 48-hour<br />

horizon. This gives the operator ample time to fix an issue before it<br />

becomes a problem.<br />

Results show that Aquasuite is able to learn and predict operations<br />

several days ahead and it can function as autopilot, able to perform<br />

unattended operation. Preliminary results up till now show that a<br />

reduction of aeration flow with predictive compared to conventional<br />

control of up to 15% is achieved. This aeration flow reduction<br />

results in corresponding energy savings.<br />


The solution demonstrates it can learn the process in such a way,<br />

that it provides two-day-ahead predictive insight while optimising<br />

and controlling the plant in real time. This means the self-learning<br />

system can act as an autopilot to the operator, increasing the<br />

operator’s productivity. It saves operational costs and increases<br />

operational resilience as it delivers a more robust system which<br />

is less sensitive to e.g. measurement failures. It provides timely<br />

insights and anomaly detection to the operator, reducing the risk<br />

and effect of undesirable events.<br />

The approach of predicting water and integrally optimising assets<br />

on a holistic level is key to this solution and can be applied across<br />

the whole water loop.<br />

performance through machine learning and control. Connecting<br />

to the plant’s Supervisory Control and Data Acquisition (SCADA)<br />

system to gather data and control key processes, it sends data out<br />

to the Aquasuite ® cloud solution through a secure data diode. With<br />

the data collected near real-time in the cloud, the software is able<br />

to track actual performance of the on-premise solution through<br />

a digital replica. More advanced analytics are made available to<br />

the operator through the cloud, including anomaly detection, soft<br />

The combination of reverse osmosis (RO) and ion exchange (IX) processes is an uncommon one,<br />

and LANXESS Sales Manager Mark Seah tells <strong>Water</strong> & <strong>Wastewater</strong> <strong>Asia</strong> (WWA) how the combination<br />

produces optimal results.<br />

WWA: Could you share with us what the<br />

combined RO and IX process entails?<br />

SEAH: RO and IX are two different technologies.<br />

IX entails using ion-exchange resin to selectively<br />

remove dissolved substances in the water. The<br />

RO process is basically removing dissolved<br />

substances by particle size, so there’s no<br />

selectivity. The two different technologies, when<br />

combined together, produce the optimal result<br />

of both chemical process and mechanical filter<br />

processing. Ion exchange can be used as pretreatment<br />

for RO to remove hardness or organics,<br />

or as post-treatment to polish the RO permeate<br />

How does this help the wastewater treatment<br />

process?<br />

Broadly, in terms of energy consumption,<br />

RO has a high consumption of energy, since<br />

the applied pressure has to overcome the<br />

osmotic pressure of the feed solution, whereas<br />

ion-exchange resin has a low consumption<br />

of electrical energy because there’s no huge pump that’s<br />

valuable substances from the waste stream, like heavy metals.<br />

required like in RO. However, in the chemical process, chemical<br />

consumption wise, RO is very low and for ion-exchange resin What challenges does this aim to solve?<br />

there’s a high utilisation of chemicals. So, for a combination of We aim to integrate this into the zero-liquid-discharge (ZLD) cycle,<br />

both, it actually moderates between electrical consumption and which is what a lot of industries and governments are looking<br />

chemical consumption. In this way, it optimises the process, not into: recycling and reusing water. By doing this, you’re actually<br />

just for wastewater. RO has to overcome the osmotic pressure and removing the footprint of water treatment.<br />

has, therefore, a higher energy requirement.<br />

What are the advantages of using this process?<br />

In terms of energy consumption and chemical consumption<br />

there’s a balance of both requirements. IX as RO pre-treatment<br />

can remove substances which can foul the membrane. Therefore,<br />

it leads to a reduction of other chemicals and avoids a flux decline<br />

of the RO system. In addition to this, it is possible to remove<br />

How would using combined RO and IX processes be different<br />

from current wastewater treatment processes?<br />

Each water treatment process has its own advantage and<br />

disadvantage. But here at Lanxess, we have 80 years of experience<br />

producing ion-exchange resin, so we know how to make ionexchange<br />

resin that is robust to use in many different kinds of<br />

applications. By combining the new knowledge and initiative that<br />

FOCUS 31<br />

Comparing the differences between reverse osmosis (RO) and ion exchange (IX) processes<br />

we put into our RO, we are able to optimise.<br />

We are able to look into several industries: Power plants, food<br />

and beverage, wastewater treatment in textile and electroplating<br />

industries. These are where we have a strong advantage<br />

in keeping a good balance between energy and chemical<br />

consumption while enabling the integration of this into the ZLD<br />

water treatment cycle.<br />

What would the challenges be in implementing these processes?<br />

The challenge would be the balance of both energy and chemical<br />

consumption. It’s always a challenge if there’s a seasonal in terms<br />

of the feed water that we are treating. In order to have an efficient<br />

combined process of ion-exchange resin and RO, we need to have<br />

good knowledge of the kind of feed water that we are treating.<br />

We can then design the flexibility of the ion-exchange resin to<br />

accommodate these variants in terms of the feed water that is<br />

coming into the system.<br />

Although we don’t have four seasons here, there’s still the<br />

monsoon season for wastewater and river water. There’s a<br />

fluctuation of this feed water at times when you have different<br />

kinds of contaminants in the wastewater, which poses a challenge.<br />

For wastewater treatment, factory to factory, they’re all different,<br />

so it’s impossible for us to design one system that we can sell<br />

to all industries. And so, we have to work very closely with the<br />

customer in finding the right solution and the right combination<br />

of technology. Ion-exchange resin can go before or after the<br />

membrane; which should go first, or to have both — this is where<br />

we need to talk to the customer a lot to find the right solution.<br />

Looking forward, do you think we will see these processes grow<br />

in popularity?<br />

At this moment we see a very strong market in <strong>Asia</strong> such as<br />

Thailand, Indonesia, the Philippines and Vietnam. These are the<br />

countries that have a strong growing demand in the industries<br />

that I’ve mentioned earlier. These are the markets that present the<br />

most opportunities or are the most attractive to our products.<br />

Sometimes, we have a problem justifying these two technologies<br />

to our customers because they seemed to be in competition with<br />

each other! But the reason why we advocate for these combined<br />

processes is that there is a way to optimise them. In a lot of<br />

remote areas, you might not have so much access to electricity,<br />

or have difficulty accessing the sufficient chemicals to do the<br />

regeneration for ion-exchange resin. A combination of both would<br />

enable a lot of such systems to be implemented in these places,<br />

and you can actually minimise any reliance on one particular<br />

technology. With the combination, it gives the customers and<br />

industries a balance of different technologies.<br />

The combination of experienced product and new initiative<br />

product – this is what we offer to the market, and to our<br />

customers. WWA<br />

32 FOCUS<br />

Having spent over 20 years in the<br />

Industrial Automation field with<br />

10 years of experience in the water<br />

and wastewater industry, Schneider<br />

Electric’s segment leader, Shanmugavel<br />

Subramaniam, is the person to talk to<br />

regarding cybersecurity in the water<br />

sector, and what challenges the water<br />

industry players must navigate in their<br />

drive towards Industry 4.0.<br />

When it comes to cybersecurity, Shanmugavel Subramaniam<br />

is of the opinion that the level of defence afforded to the<br />

water industry depends on its level of consideration as a<br />

critical infrastructure.<br />

“In some countries, water is a part of a critical infrastructure – in one<br />

aspect you don’t want its security to be compromised resulting in<br />

operational disruption that may lead to losing supply of water. This<br />

is the case in Singapore, where the importance in supplying water<br />

24/7 is significant and there is no compromise in any shortage of<br />

water, which is deemed as a critical infrastructure. The industry here is<br />

trying to figure out how to implement cybersecurity at the operational<br />

technology (OT) level, and there’s still a lot of work to be done.”<br />


Adding on to his statement, Shan said that impact of Industry 4.0<br />

can be broken into three core aspects: People, Assets/Equipment<br />

and Operation.<br />

“Similarly, in the water utility this transformation takes place with<br />

technologies like Industrial Internet of things (IIOT) by making<br />

the equipment ‘talk’. Imagine a situation when a vast number of

FOCUS 33<br />

equipment is talking in many different ‘languages’, this creates<br />

‘noises of data’ that need to be managed & analysed – in other<br />

words, big data analytics. A single platform is required with<br />

the ability to consolidate, analyse & translate this data into<br />

meaningful operational & business information like a unified<br />

command centre, with one unified operational language,” he<br />

explained.<br />

<strong>Water</strong> utilities need to see the whole water cycle picture to know<br />

about what’s happening in their operation, but the utilities today<br />

don’t have this vision. As the various equipment are made to<br />

‘talk’, all the various departments tend to focus only on their own<br />

processes and work in individual silos, but they need to work<br />

together to have an integrated view of the whole operation.<br />

In the past, people relied on their own knowledge to figure out if<br />

the equipment is working and needed to update their colleagues<br />

manually. But now that machines are starting to talk, everyone<br />

gains better visibility on the entire process thus increasing<br />

transparency. This transformative shift from manually reporting<br />

information to machines providing insight is the essence of<br />

Industry 4.0.<br />

Shan also observed that as a concept, Worker 4.0 would have to<br />

reach far beyond the current generation of operators, to prepare<br />

for the next batch of workers: Generation Z, or Gen Z for short.<br />

“They’re the technology-smart generation. When they graduate<br />

and come out into the workforce, they expect technology to be<br />

helping them. That’s one key reason the acceleration (of Industry<br />

4.0) is faster now, because the industry needs to be ready for the<br />

next generation.”<br />


However, one key issue in adapting to Industry 4.0 lies in setting<br />

standards – in terms of cybersecurity, how do operators know<br />

when a plant or operation is secure?<br />

Shan explained, “Cybersecurity is a continuous discussion –<br />

in a laptop for example, when you plug a thumb drive or new<br />

vulnerability is present, it immediately downloads software<br />

patches and updates. Imagine if that goes into an industry’s<br />

operation. How will the management of such security patches be<br />

handled?<br />

However, this shift towards a streamlined process is bound to<br />

create a new set of problems that need to be tackled head-on for<br />

the industry to move forward. Perhaps the most obvious problem<br />

would be the risk of machines completely replacing the workers<br />

as processes become increasingly transparent, thus requiring less<br />

manual oversight.<br />

The real question though, is if the utilities are ready for this and<br />

how they are adapting.”<br />


According to Shan, much of the impact caused by the shift to<br />

Industry 4.0 would be in terms of operational behaviour.<br />

“As processes become increasingly transparent, operations will<br />

change, and silos will be broken down for greater integration.<br />

Operational behaviour will be affected, and typical feedback from<br />

operators becomes: ‘Will I lose my job?’. It’s a big challenge for<br />

water utilities. So, operators need to be trained to become what<br />

Singapore calls ‘Worker 4.0’ or ‘digital workers’.<br />

Moving towards Industry 4.0 is a big concern for any industry –<br />

but technology is not going to replace people. What will happen<br />

instead is that it will upskill talents, change job descriptions<br />

and working behaviours leading to a change management in<br />

operations,” he said.<br />

What are the guidelines operators need to follow if they want<br />

to implement talking equipment, for example? What security<br />

guidelines should they have? Every industry has its own needs to<br />

address, and the water industry is a bit different because it links<br />

back to the public. You cannot hack drinking water unless you<br />

contaminate it, but you can disrupt the operation and supply of<br />

water.<br />

In Singapore, the Cyber Security Agency (CSA) - founded in April<br />

2015 – helps engage with various industry segments to heighten<br />

cyber security awareness & guidelines as well as to ensure the<br />

development of Singapore’s cyber security standards.<br />

Critical infrastructure requires secured segment and network<br />

authentication but how can we enable it for OT? The IT equivalent<br />

is a zero-trust network, where you must authenticate all processes<br />

within the network as nothing is trusted. Considering the critical<br />

nature of our water utilities, this is most likely the type of OT<br />

network that they will want to implement.<br />

However, such a transformative paradigm shift will require<br />

management to come up with a plan on how to integrate these<br />

technologies without disrupting their core operational services.”<br />

As the most widely used raw material in the pharmaceutical manufacturing<br />

process, water is an essential part of the production, processing, and<br />

formulation of pharmaceutical products. <strong>Water</strong> & <strong>Wastewater</strong> <strong>Asia</strong> (WWA) sits<br />

down with Veolia’s Market Manager, Tiyo Kok Fong, to learn more about how<br />

water is used in this industry and how wastewater from this process is treated.<br />

Tiyo Kok Fong,<br />

Market Manager, Veolia<br />

WWA: What is the importance of water in manufacturing for the<br />

pharmaceutical industry?<br />

KOK: The pharmaceutical industry requires consistent high-quality<br />

water for manufacturing, including product addition and dilution (as<br />

an ingredient in a dosage form), equipment washdown and rinsing,<br />

even as solvent or diluent for research in laboratory processes. With<br />

its polarity and hydrogen bonds, water possesses many unique<br />

chemical properties — allowing it to dissolve, absorb, adsorb, or<br />

suspend many different compounds. These include contaminants<br />

that may represent hazards in and of themselves, or that may be<br />

able to react with intended product substances, resulting in hazards<br />

to health.<br />

The major compendia (USP, EP and JP) require pharma<br />

manufacturers to begin with drinking water and purify it further to<br />

specific standards — depending on the use, such as purified water<br />

(PW) or water for injection (WFI) — as specified in monographs,<br />

which provide the baseline requirements for water used in<br />

pharmaceutical manufacturing processes.<br />

Typical wastewater treatment plants are constructed to remove<br />

solid substances, degradable organic substances, and nutrients.<br />

Many endocrine disrupting chemicals (EDCs) or potentially<br />

harmful substances are not biologically degradable and are hardly<br />

absorbable. Hence, only very little amounts are removed or are<br />

not removed at all. Some studies in the West had highlighted the<br />

negative impact of Endocrine Disruptors in the Environment. So far,<br />

there is no regulation overall to seize the threats from EDCs.<br />

However, in the <strong>Asia</strong> Pacific region, the tightening of wastewater<br />

discharge limits and the enforcement of environmental regulations in<br />

many countries has led to greater demands for more sophisticated<br />

and innovative treatment technologies and solutions.<br />

Control of water quality, in particular the microbiological quality,<br />

is a major concern and the pharmaceutical industry devotes<br />

considerable resources to the development and maintenance<br />

of water purification systems. Subject matter experts (SMEs) of<br />

pharmaceutical manufacturers work closely with the compendial<br />

water/steam vendors to define and review compendial water<br />

and steam generation systems, as well as associated process<br />

manufacturing controls within the system that may potentially affect<br />

product quality and patient safety.<br />

WWA: How is wastewater from manufacturing in this industry<br />

dealt with, and how have treatment/disposal methods evolved in<br />

the past five years?<br />

KOK: <strong>Wastewater</strong> from the pharmaceutical industry is highly charged<br />

with TOC, COD, BOD, suspended matter or solvents, so it is imperative<br />

that manufacturers treat it before discharging the effluent.<br />

EVALED ® evaporators are low energy consumption and low CO 2 footprint<br />

With sustainability being a common concern for many<br />

companies, Veolia aims to reduce energy needs by<br />

reusing water. <strong>Wastewater</strong> treatment also offers many<br />

opportunities to recover valuable elements. In addition,<br />

there is also a growing trend of single-use technologies<br />

in product manufacturing facilities that has reduced<br />

water consumption but increased the amount of plastic<br />

waste.<br />

The Orion is a sustainable solution with the potential to reduce overall<br />

water and energy consumption, as well as produce water that meets all the<br />

requirements of the new WFI Monograph<br />

<strong>Water</strong> is a major ingredient for most bulk waste and can be further<br />

treated with EVALED — a technological solution for disposal cost<br />

reduction and product recovery. <strong>Water</strong> can be reused for nonprocess<br />

purposes, and Minimum Liquid Discharge (MLD) or Zero<br />

Liquid Discharge (ZLD) may even be achieved within the ETP. For<br />

an effective way to remove micro-pollutants, companies may also<br />

choose to adopt the EXENO — Veolia’s solution for an effective<br />

and economically friendly biological removal of drug residues in<br />

wastewater that is based on the AnoxKaldnes MBBR.<br />

Sustainability is also a growing concern and many companies<br />

are looking at ways to maximise resources and develop a plan for<br />

sustainable growth. This often also helps companies fulfil their CSR<br />

commitments. Some options that companies are turning to include<br />

recycling wastewater for non-potable uses, turning wastewater into<br />

a resource through sludge treatment or biogas production, and<br />

dealing with the issue of drugged water and micropollutants.<br />

WWA: What are some of the risks associated with wastewater<br />

treatment in this industry, and how can companies deal with these<br />

risks?<br />

KOK: <strong>Water</strong> scarcity and tightening regulations have aggravated<br />

risks for the industry, particularly because of the high volume of<br />

water required. Unlike other raw materials, the quality of potable<br />

water varies significantly from one region to another, as well as from<br />

season to season. The quality and characteristics of the potable<br />

water supply have an important bearing on the purification regime<br />

required to produced purified water for use in the pharmaceutical<br />

manufacturing process.<br />

Changes in local regulations, such as the tightening discharge limits<br />

and quality of effluent discharged into the environment, have had a<br />

significant impact on the decisions that companies make regarding<br />

their water facilities, as well as water and wastewater treatment<br />

options.<br />

WWA: What are some of the challenges faced in the<br />

storage of water or water treatment in this industry?<br />

How do companies overcome these challenges?<br />

KOK: Storage tank and distribution systems are potential<br />

sources of contamination, particularly from bacteria.<br />

Good design and proper maintenance regimes are<br />

needed to minimise issues. With over 100 years of<br />

experience in water storage and distribution in larger<br />

markets such as municipal services, Veolia is able to<br />

adapt good design practices to help pharmaceutical companies<br />

reduce the risks surfacing from the storage and distribution of water<br />

— from the pre-treatment system to hygienic areas, such as PW and<br />

WFI storage and distribution.<br />

WWA: What technologies does Veolia have that are focused on<br />

water/wastewater treatment for the pharmaceutical industry?<br />

How does Veolia contribute?<br />

KOK: Veolia’s expertise enables us to offer complete solutions<br />

for quality water production and wastewater treatment for the<br />

pharmaceutical industry. From solutions for pre-treatment, PW or<br />

WFI, to solutions for storage, distribution or effluent treatment<br />

services, Veolia applies the latest technologies to improve<br />

production efficiency and reduce operating costs for customers —<br />

without compromising the safety of processes or product quality.<br />

For example, the Orion ® is a sustainable solution with the potential<br />

to reduce overall water and energy consumption, as well as produce<br />

water that meets all the requirements of the new WFI Monograph.<br />

The POLARIS can be used for distillation in the production of water<br />

for injection and highly purified water, while the EXENO works to<br />

remove COD/BOD, Endocrine Disruption Chemicals (EDCs), and<br />

nutrients from wastewater.<br />

The AQUAVISTA digital service platform is Veolia’s response<br />

to customer calls for data-driven optimisation in the water and<br />

wastewater treatment industry. Features like predictive maintenance<br />

and real-time optimisation taps on the latest innovation in IoT and<br />

artificial intelligence-based analysis — bringing about a plethora of<br />

benefits. These include allowing treatment plants to automatically<br />

adapt to various events and reduce operational expenditure. With<br />

this platform, customers can gain more meaningful insights and<br />

understanding of the water and wastewater treatment processes<br />

in their plant, and make informed decisions about optimising water<br />

consumption or the manufacturing process as a whole. WWA<br />

As one of the country’s Four National Taps, desalination has been a key part of Singapore’s water<br />

story since the first desalination plant was opened in 2005. As Singapore seeks to add the<br />

Jurong Island Desalination Plant (JIDP) to its map of desalination plants, <strong>Water</strong> & <strong>Wastewater</strong> <strong>Asia</strong><br />

understand how the country is doing in terms of its desalination efforts and how IDE Technologies<br />

plays a part in the process.<br />

WWA: How is Singapore doing in terms of its current desalination<br />

efforts?<br />

ROSENFELD: Currently, Singapore desalinates 25% of its water<br />

demand and PUB, the Public Utilities Board, is set to reach the 30%<br />

mark by 2060 ahead of the 2061 expiration of the <strong>Water</strong> Transfer<br />

Agreement with Malaysia.<br />

On the same note, PUB plans to expand NE<strong>Water</strong>, Singapore’s brand<br />

name for potable-quality water produced from treated sewage,<br />

to meet roughly 55% of the national water demand by 2060. In<br />

Singapore, there are currently four large desalination plants which<br />

serve as part of the four main sources of water for the country.<br />

WWA: Please tell us more about the SWRO plant that will be<br />

supplied by IDE Technologies for the upcoming JIDP.<br />

ROSENFELD: IDE Technologies has been awarded the contract<br />

to deliver a reverse osmosis (RO) system for the JIDP. This plant<br />

will be Singapore’s fifth desalination plant and have a capacity of<br />

35.7 MGD (135,000 m 3 /d). This combined system will produce<br />

high-quality water to Singapore. As Singapore is a small city-state<br />

with limited water storage space, its water management policy is<br />

essential to its existence.<br />

Chen Rosenfeld, Sales & Solutions Manager<br />

for <strong>Asia</strong>-Pacific, IDE Technologies<br />

Large desalination plants are part of the four main sources<br />

providing water across the city, in addition to water imported from<br />

Malaysia, extensive rain water collection, and storage and water<br />

reuse facilities distributing water to potable quality. Singapore<br />

has set a target to have desalinated water meet up to 30% of the<br />

country’s future water needs by 2060. JIDP will be completed in<br />

WWA: What are the challenges facing countries in <strong>Asia</strong><br />

that want to adopt desalination?<br />

ROSENFELD: The main challenges facing countries wanting<br />

to adopt desalination is a regulatory framework<br />

that will allow for Public-Private-Partnership<br />

(PPPs) and long-term concessions so<br />

private initiatives and investments<br />

will provide the needed capital and<br />

expertise to implement desalination<br />

at a very competitive and affordable cost.<br />

Streamlined environmental permitting and other<br />

permitting processes also pose a challenge in <strong>Asia</strong>n<br />

countries. In addition, the distribution networks and sewage<br />

treatment plants (STPs) also pose a challenge for utilities.<br />

Singapore, Formosa Taiwan and other desalination plants in <strong>Asia</strong><br />

WWA: How will IDE Technologies’ provision of RO solutions to<br />

the JIDP aid Singapore in its desalination efforts?<br />

ROSENFELD: The 135,000 m 3 /day (35.7 MGD) Sea <strong>Water</strong> Reverse<br />

Osmosis (SWRO) plant supplied by IDE to the Jurong Island<br />

desalination project is a significant addition to Singapore’s water<br />

security and independency. This plant will be Singapore’s fifth<br />

desalination plant and produce high-quality water for the country<br />

to help meet growing demand.<br />

WWA: How widely accepted is the desalination process in <strong>Asia</strong>?<br />

ROSENFELD: Desalination of sea water and brackish water is<br />

widely accepted in <strong>Asia</strong> and while Singapore is spearheading<br />

these efforts in the region, Taiwan, Thailand, India, China and<br />

Korea are also adopting this drought-proof solution to secure<br />

drinking water as water scarcity continues to be a growing<br />

problem.<br />

WWA: What is the impact of desalination in the <strong>Asia</strong>n region?<br />

How has it changed?<br />

ROSENFELD: Desalination is still a very small portion of the<br />

To overcome these challenges, the government must embrace<br />

Public-Private Partnerships to help expedite desalination<br />

infrastructure so the economy can have another droughtresistant<br />

method for access to a continuous supply of clean<br />

water. Environmental permitting also needs to be streamlined so<br />

innovative companies can deliver desalination processes that are<br />

offer increased efficiency and decreased energy usage.<br />

WWA: Going forward, where do you think the water industry in<br />

<strong>Asia</strong> is headed? What trends should companies look out for?<br />

ROSENFELD: IDE sees tremendous potential in the emerging <strong>Asia</strong>n<br />

water industry. In <strong>Asia</strong>, we believe that there will continue to be<br />

increased focus on eco-friendly water solutions. Chemicals like<br />

chloramine, a combination of chlorine and ammonia, can be quite<br />

toxic to the environment and when used as a disinfectant in water,<br />

chloramine can be fatal to fish and frogs.<br />

When used for water treatment, chloramine can cause a<br />

50% increase in power consumption and its by-products can<br />

have detrimental effects on humans. Chloramine can form<br />

N-Nitrosodimethylamine (NDMA), which is an organic contaminant<br />

suspected as carcinogenic. With eco-friendly water solutions, no<br />

chemicals are used in the process to clean or disinfect the water<br />

which protects everyone from the effects of harmful chemicals –<br />

and <strong>Asia</strong> is leading the way in adoption of these solutions. WWA<br />

Metal finishing industries<br />

(automotive, electronics,<br />

aerospace, hardware, jewellery,<br />

heavy equipment, appliances, tires, and<br />

telecommunications) generate wastewater<br />

with a high concentration of contaminants<br />

such as heavy metals, organic substances<br />

and inorganic acids. When it comes to<br />

heavy metals – nickel, zinc, tin, silver,<br />

lead, copper, chromium and cadmium<br />

are typically present in metal finishing<br />

industrial effluent, and are a big concern<br />

due to their toxicity to human and other<br />

biological life.<br />

Currently, the metal finishing industrial<br />

effluents are treated with traditional<br />

chemical methods that include the<br />

precipitation of heavy metals by<br />

neutralisation, flocculation and settling/<br />

clarifiers for discharge. The sludge will<br />

pass through a filter press to remove<br />

the solids, and the liquid will go for<br />

another cycle. This method requires a<br />

lot of chemicals and a good solid waste<br />

management system to handle the<br />

precipitated heavy metal sludge.<br />

In many cases, the treated water does<br />

not meet the discharge requirement due<br />

to a high amount of total dissolved solids<br />

(TDS). In such cases, it needs to be diluted<br />

with tap water to meet the discharge<br />

limit, or conventional evaporators and<br />

crystallisers need to be deployed to treat<br />

the salinity for discharge or reuse. Figures<br />

1 and 2 show the conventional metal<br />

finishing industrial effluent treatment<br />

methods with and without an evaporator<br />

and crystalliser. As the conventional<br />

method consumes a large quantity of<br />

chemicals and the evaporation method<br />

requires very high CapEx and OpEx, there<br />

is a growing need for a cost-effective,<br />

chemical-free method to handle the metal<br />

finishing industrial effluent treatment.<br />

Membrane Distillation (MD) is a fairly new<br />

process that is being considered worldwide<br />

as a low cost, energy-saving alternative to<br />

conventional separation processes such<br />

as distillation and multi-stage evaporation.<br />

In MD, a membrane permeable to vapour<br />

but impermeable to liquid water separates<br />

a heated water stream from the product<br />

stream. <strong>Water</strong> vapour from the heated<br />

stream passes through the membrane due<br />

to the gradient in the vapour pressure and<br />

condenses in the product stream.<br />

<strong>January</strong> / <strong>February</strong> <strong>2020</strong> • waterwastewaterasia.com

FOCUS 39<br />

MD is a good option to treat wastewater<br />

containing inorganic content, but current<br />

MD membranes are limited to treating<br />

industrial wastewater containing high<br />

organic content. The membranes are very<br />

sensitive to acid and organic solvents<br />

that will alter the membrane surface,<br />

leading to membrane wetting. If the<br />

membrane undergoes wetting, it allows<br />

the contaminant to pass through the<br />

membrane.<br />

Several methods have been explored to<br />

prevent membrane wetting. The current<br />

solution to wetting is to apply a finely<br />

porous hydrophobic coating which helps to<br />

increase hydrophobicity while maintaining<br />

acceptable porosity. However, it reduces<br />

the pore size of the membrane, which<br />

reduces performance. Another method to<br />

increase hydrophobicity is by introducing<br />

fluoride-containing polymers or additives<br />

into the dope solution.<br />

as a post-treatment to the IMD system<br />

to recover more water, helping the whole<br />

system achieve zero liquid discharge (ZLD).<br />

Figures 3 and 4 show the novel methods<br />

for metal finishing industrial effluent<br />

treatment with minimum liquid discharge<br />

(MLD) and ZLD.<br />

Recently, two different case studies were<br />

carried out for metal finishing industries in<br />

Singapore. Both case studies were carried<br />

out without a crystalliser, and only focused<br />

on MLD. From the results shown, there<br />

is a high possibility for circular economy<br />

in metal finishing effluent treatment. The<br />

first case study was conducted based on<br />

the process described in figure 3. The<br />

pre-treated effluent was used to study the<br />

maximum water recovery from the TS-30<br />

IMD system.<br />

The feed water was heated up with an<br />

electrical boiler to 70±3 °C and supplied<br />

to the feed inlet of the membrane module<br />

by a circulation pump with a velocity of<br />

0.42m/s. A vacuum pressure of -0.2 bar<br />

Memsift Innovations Pte Ltd has developed<br />

STOMATE ® , a highly hydrophobic fibre<br />

membrane suitable for MD application<br />

– STOMATE ® is created with proprietary<br />

materials that contain 10X higher fluorine<br />

atoms per unit compared to current<br />

materials, and can overcome the wetting<br />

issue in MD.<br />

Figure 3: The novel methods for metal finishing industrial effluent treatment with MLD<br />

In addition to this, Memsift also has an<br />

Improved Membrane Distillation (IMD)<br />

process (TS-30) that utilises the<br />

temperature difference and pressure<br />

difference across the membrane as<br />

driving force. Memsift has also developed<br />

GRAVITY, a new generation crystalliser<br />

which works in the principle of centrifugal<br />

and gravitational force with some<br />

temperature differences. The newlydeveloped<br />

crystalliser requires one-third<br />

of the energy that is currently being used<br />

for conventional crystallisers. The IMD<br />

system can be operated with minimum<br />

pre-treatment for the metal finishing<br />

industry and the crystalliser can be used<br />

system. The following table shows the quality of feed permeate<br />

Another case study was conducted using the same method<br />

described in Figure 3. All the operating conditions were kept<br />

copper chloride. Hydrochloric acid (12.5%) was collected as the<br />

permeate and a slurry (saturated solution) of copper chloride was<br />

collected in the concentrate side. Here the liquid-waste become<br />

valuable products (hydrochloric acid and copper chloride) and<br />

potentially both can be reused in the process again after some<br />

minor purification process. This case study shows the possibility of<br />

making circular economy from metal finishing industrial effluent.<br />

KSB Guard shows how it can help a<br />

system runs smoothly and minimise<br />

outlay for inspection and maintenance.<br />

It offers the ability to gain an overview<br />

of the data on all the pumps without<br />

having to be physically on site.<br />

By Bryan Orchard<br />

Call it Industry 4.0, digitalisation or<br />

digital transformation — the concept<br />

behind these words has been and still<br />

is on everybody’s lips. Frequently, however,<br />

it gives rise to the question how to actually<br />

tackle the challenge of digitalising an<br />

established plant, namely a brownfield plant.<br />

If pumps are involved, it raises the<br />

questions: How can pumps be made fit for<br />

the future? How can procedures surrounding<br />

pump maintenance and service be improved<br />

using digitalisation? How can pumps<br />

become smart? Is there an option of making<br />

a concrete start without major expense?<br />

Pump and valve manufacturer KSB SE & Co.<br />

KGaA, has addressed these questions with<br />

a monitor that was first introduced in late<br />

2018, and which is now been taken up by<br />

several major international manufacturers.<br />

The monitoring device, called KSB Guard,<br />

enables the transfer of existing pumps to the<br />

digital world, even during operation.<br />


The compact device comprises a sensor<br />

unit housing a temperature and a vibration<br />

sensor. The vibration sensor has an<br />

accuracy of 1 kHz and measures in all<br />

three axes. The sensor unit is fastened to<br />

the pump (KSB or any other make) using<br />

industrial adhesive. This type of fastening<br />

is generally suitable for all dry-installed<br />

pumps and can even be fitted during pump<br />

operation (Figure 1).<br />

The second hardware component is a<br />

transmission and battery unit, which is<br />

connected to the sensor unit with a cable<br />

and supplies the sensors with power. This<br />

does away with the need to install an<br />

additional mains power cable to the sensors<br />

at the pump. The batteries have a life of up<br />

to five years and are easy to replace.<br />

Using a wireless connection, the data<br />

recorded are sent to a gateway, which<br />

is the third hardware component. The<br />

gateway can be used for up to 20 sensor<br />

units and fitted with a SIM card, it provides<br />

the required connection to the mobile<br />

phone network. This means the entire<br />

communication path has been defined and<br />

secured by KSB, minimising time and costs<br />

for installation and commissioning.<br />

To access the available information about a<br />

pump, the pump only needs to be assigned<br />

in the KSB Guard app or web portal and the<br />

name plate data of pump and motor need<br />

to be entered. If it is a KSB pump and its<br />

serial number is entered, the data will be<br />

called up from KSB databases and entered<br />

automatically. Even in all other cases,<br />

entering the data takes no longer than a<br />

few minutes and is as easy as filling in an<br />

entry screen in an online shop. There is no<br />

further requirement for setting any other<br />

parameters. The complete installation and<br />

commissioning process is so efficient, it<br />

is easy to make existing pumps in a plant<br />

smart and, with that, fit for the future.<br />

After commissioning, a multitude of<br />

information will be accessible in the web<br />

portal or app. For pumps made by KSB<br />

the serial number gives access, via app or<br />

web portal, to additional documents, such<br />

as the data sheet or a sectional drawing,<br />

so searching for pump information has<br />

become a thing of the past. Quickly and<br />

easily maintaining and calling up a history<br />

file for the pump is also an option. Any<br />

maintenance and repair work can be<br />

recorded with a few clicks and will then be<br />

visible to all those responsible (Figure 2).<br />

Particularly valuable are the status data<br />

restricted to the current temperature and<br />

mean vibration velocity values, but also<br />

show trends. Since measurements are<br />

conducted once an hour or more frequently<br />

if needed, data can be examined over time,<br />

which enables any changes to the pump<br />

status to be identified. Alarm and warning<br />

limit values have also been defined for this<br />

purpose. If the limit values are reached,<br />

an alarm or warning message is triggered.<br />

These messages can be received by e-mail<br />

or as a push message on a mobile phone<br />

or tablet — whichever is most convenient<br />

(Figure 3). The limit values can be<br />

individually adjusted for each pump using<br />

the app or web portal.<br />

Apart from information on the temperature<br />

and mean vibration velocity, an operating<br />

hours counter, the load profile and the load<br />

status of the pump can be displayed. The<br />

speed can be derived from the measured<br />

vibrations. Initially, this indicates whether<br />

the pump is running or at standstill. For<br />

pumps without a variable speed system,<br />

the speed and an algorithm patented by<br />

KSB provide the facility to further identify<br />

the load condition of the pump, overload,<br />

optimum, part load or extreme part load. In<br />

this way, KSB Guard also helps to uncover<br />

energy saving potentials and optimise<br />

plants accordingly.<br />

KSB Guard’s main benefit is certainly<br />

that of monitoring the temperature and<br />

vibrations and the associated warning<br />

and alarm messages, which help identify a<br />

change in pump status at an early stage.<br />

This allows an early response before any<br />

failures or major damage occurs at the<br />

pump. The early-warning system has been<br />

tried and tested in many applications.<br />


For example, the imminent clogging of a<br />

large, dry-installed waste water pump at a<br />

pumping station was detected at an early<br />

stage, thereby avoiding a problem. As the<br />

pumping station in question transports raw<br />

waste water, clogging is a common even<br />

and in the past this had led to numerous<br />

failures and costly repairs. What made<br />

it more difficult was that the pumping<br />

station was in a remote location and not<br />

supervised continuously. KSB Guard proved<br />

to be an ideal solution, providing the<br />

pumping station with a monitoring system<br />

in a simple and cost-effective way.<br />

In this particular case, KSB Guard detected<br />

that the mean vibration velocity was rising<br />

continuously. Based on this knowledge, service<br />

personnel were sent to the pumping station to<br />

remedy the cause of the high vibrations and<br />

prevent clogging. Without KSB Guard, a failure<br />

and the corresponding damage at the pump<br />

would have most likely been the outcome.<br />

Another example is that of a tubular casing<br />

pump that had been in operation for many<br />

years without any maintenance because<br />

the plain bearings were lubricated for life.<br />

However, after a very long period of use, more<br />

than 40 years in this case, these mechanical<br />

components were affected by wear. To ensure<br />

continued maximum operating reliability, KSB<br />

Guard was identified as the first choice as it<br />

allowed the pump to be simply and quickly<br />

fitted with an effective monitoring system.<br />

As in the previous example, the vibration<br />

values measured had increased over time. It<br />

was then discovered that the pump could no<br />

longer be rotated by hand. As a consequence,<br />

the pump was dismantled to prevent a failure<br />

incurring very costly repairs or even the need<br />

to purchase new equipment.<br />

With KSB Guard, every pump is quickly and<br />

easily integrated in the “Industrial Internet of<br />

Things”, and an existing pumping station can<br />

be given a new level of transparency without<br />

any risks. WWA<br />

VIEWPOINT 43<br />

Artificial intelligence (AI), machine learning technologies offer possibilities for operation<br />

efficiencies in water infrastructure<br />

By William Yong, Managing Director, Southeast <strong>Asia</strong>, <strong>Water</strong>, Black & Veatch<br />

Thanks to rapidly-advancing technology and<br />

As a key element of digital transformation, the<br />

innovation, AI is perceived as a key pillar<br />

popularity of AI stems from its adaptability in many<br />

of urban water treatment and Southeast<br />

sectors. By facilitating right-sized, data-driven<br />

<strong>Asia</strong>n governments are now racing to establish the<br />

region as an AI hub. For example, Singapore has<br />

launched its National Artificial Intelligence Strategy<br />

investments, digital transformation offers utilities in<br />

<strong>Asia</strong> the opportunity to find strategies that address<br />

their different needs.<br />

and committed over $500 million to fund activities<br />

related to AI under the Research, Innovation and<br />

Enterprise <strong>2020</strong> Plan.<br />

At the core of digital transformation is aggregating,<br />

mapping and analysing data for greater insight and<br />

Not to be outdone, Malaysia has set up a one-billiondollar<br />

AI park to boost research and development in<br />

William Yong<br />

actionable information. Connected sensors provide<br />

data that supports deeper analysis, and actionable<br />

learnings are then generated from the analysis.<br />

the country, and the Philippines is working with the <strong>Asia</strong>n Institute<br />

of Management (AIM) Aboitiz School of Innovation, Technology and<br />

Entrepreneurship (ASITE) to prepare a roadmap which will position<br />

Here, we identify and predict possible opportunities for the <strong>Asia</strong>n<br />

water sector in the coming years.<br />

the country as an AI leader in Southeast <strong>Asia</strong>.<br />

A digital twin is a digital representation of water treatment and<br />

distribution infrastructure, with AI embedded into the digital<br />

twin. A water utility digital twin offers the prospect of optimising<br />

performance of existing assets and increasing the efficiency with<br />

which they are operated and maintained. The twin supports this<br />

by facilitating systems thinking — combining multiple internal and<br />

external data sources across the asset base with predictive analytical<br />

techniques served through multiple functional views. This enables<br />

improved insights that support better decisions, leading to better<br />

outcomes in the physical world. Photo credit: Black & Veatch<br />

<strong>January</strong> / <strong>February</strong> <strong>2020</strong> • waterwastewaterasia.com

44 VIEWPOINT<br />

Prediction #1: The <strong>Asia</strong>n water sector launches numerous AI pilot projects<br />

Regional water leaders are assessing digital technologies to<br />

extend the value of existing water infrastructure while solving the<br />

complexities of underdeveloped or aging water infrastructure, as<br />

well as non-revenue water (NRW).<br />

Prediction #2: Leaders extend AI to various parts of the water value chain<br />

AI deployments will be extended to the water treatment process,<br />

decentralisation of water supply systems and infrastructure<br />

planning. <strong>Water</strong> and wastewater utilities will consider<br />

incorporating AI to improve the removal of nutrients by<br />

wastewater treatment plants, improve effluent quality and meet<br />

regulatory requirements.<br />

More pilot projects that focus on optimising distribution systems,<br />

treatment efficiency and asset management to deliver reliable<br />

and sustainable water supply and wastewater treatment will be<br />

launched.<br />

The water sector will also combine AI and machine learning<br />

with remote monitoring technologies to enhance efficiency from<br />

decentralised water supply systems. Utilities will refer to learnings<br />

generated from analysis to optimise risk-based strategies for assetreplacement<br />

investments – this will drive infrastructure planning and<br />

offer possibilities for urban water treatment designs.<br />

Prediction #3: Regional water leaders integrate predictive maintenance into their strategies<br />

Regional utilities will pilot more predictive analytics projects, such<br />

as predictive maintenance. Predictive maintenance uses machine<br />

learning, pattern recognition and advanced analytics to optimise,<br />

manage and deliver interventions. These interventions will give<br />

water utilities in <strong>Asia</strong> the opportunity to prioritise mission-critical<br />

investments through identifying equipment and processes that<br />

could result in the highest cost of failure.<br />

As water utilities seek to improve customer service and meet quality<br />

and environmental regulatory targets, predictive maintenance<br />

will be recognised by water leaders as a critical pillar of digital<br />

transformation. One result from predictive maintenance is minimising<br />

loss from NRW through leak detection and replacing fewer pipes.<br />

Prediction #4: Regional water leaders refine processes for systemic data integration<br />

To optimise the distribution system, some regional utilities<br />

are relying on sensors for flood prediction while others have<br />

implemented hydraulic modelling to manage stormwater runoff.<br />

Several utilities are adopting remote sensors to integrate geospatial<br />

data with pipe condition analysis to minimise NRW.<br />

While utilities are making steady progress, data is likely to reside in<br />

Prediction #5: The rise of digital twins in <strong>Asia</strong><br />

There will be a higher level of urgency in the region as it assesses<br />

opportunities to address water sustainability and security to meet<br />

the needs of rapidly growing populations and economies.<br />

One opportunity it will assess is the creation of digital twins,<br />

Prediction #6: AI reframes industry roles<br />

<strong>Water</strong> professionals will see the potential of AI for changing rather<br />

than losing roles. AI relies on data, but without the insight of people<br />

who are intimate with how assets have been designed and built, and<br />

how they will behave, the data is meaningless and the AI unfit for<br />

purpose. Expertise from a variety of disciplines across the utility will<br />

be necessary to provide insight into data patterns, and teach the AI<br />

how to recognise failures and what optimum performance looks like.<br />

The opportunity is in water industry professionals thinking of AI as<br />

information silos. Digital water — through next-generation collection<br />

devices and predictive analytics — can funnel disparate data into<br />

a single, meaningful snapshot of the entire water ecosystem. This<br />

allows users to gain insight on the connectivity and synergies within<br />

a system to drive operational efficiency and optimise workforce<br />

needs. Data has the power to understand, manage and guide us to<br />

reliability and optimisation.<br />

which enable predictive capabilities and intuitive decision support<br />

and intervention. The twin is in constant dialogue with its physical<br />

counterpart, enabling utilities to simulate and scenario-test options<br />

before putting them into action in the real world.<br />

another component of the water industry workforce. It can learn, but<br />

it needs to be taught; and then the AI needs to gain experience while<br />

operating under close supervision from those who know the assets well.<br />

The result will be a blended workforce of artificial and human<br />

intelligence – Engineer 2.0. The need for asset experts to be closely<br />

involved in the planning, implementation, training and operation of the<br />

AI will help the experts develop trust in the system.<br />

The future of AI holds much potential. Invariably, the path to<br />

digital transformation success starts with an open mind and<br />

leadership that values connectivity, innovation and automation,<br />

and is realised by a workforce that understands shared, real-time<br />

common data is the way forward and empowers them to further<br />

develop themselves, participating in the digital disruption. WWA<br />

HOTSEAT 45<br />

Pani Energy CEO Devesh Bhadradwaj speaking at the recent H 2 O <strong>Asia</strong> Demo Day<br />

Pani Energy came from humble beginnings<br />

(it first started through research at<br />

the University of Victoria in Western<br />

Canada), and has now made a name for itself<br />

through the development of new technologies<br />

and its focus on improving efficiencies in<br />

the desalination and industrial wastewater<br />

treatment industries.<br />

The move past digital transformation’s initial novelty is<br />

a disappointing one, as users find previously industrychanging<br />

technologies may not deliver on everything they<br />

promised to. Pani Energy’s CEO, Devesh Bhadradwaj, takes<br />

us through how the company makes the most of artificial<br />

intelligence (AI) and machine learning to assist plant<br />

operators beyond cursory data monitoring.<br />

Said Pani Energy CEO Devesh Bhadradwaj,<br />

“We found that the water industry has been<br />

underserved by digital technologies, and there<br />

are many reasons for that – but the bottom-line<br />

is, this has created inefficiencies in operations.<br />

The price of desalination and wastewater is<br />

also much higher than normal freshwater<br />

treatment, and there’s a huge need to reduce<br />

these costs and improve efficiencies.”<br />

To do this, Pani Energy worked on harnessing<br />

AI, machine learning and deep domain<br />

knowledge in process modelling to improve<br />

plant efficiency at a low cost. With the creation<br />

<strong>January</strong> / <strong>February</strong> <strong>2020</strong> • waterwastewaterasia.com

46 HOTSEAT<br />

of Pani Digital TM – the industry’s first Digital<br />

Operator Coach – Pani Energy now had<br />

an artificially intelligent expert looking at<br />

plant operational data in real-time, showing<br />

operators what they could do to optimise the<br />

plant they’re running.<br />

Explained Bhadradwaj, “Our technology<br />

doesn’t just visualise data, it can tell the<br />

operators to change a specific set-point,<br />

indicate when sensors have gone adrift,<br />

or recommend the optimal time to clean a<br />

membrane. We looked at this industry and<br />

we realised why digital technologies and<br />

AI haven’t been adopted at this wide scale:<br />

there’s a lot of buzz, a lot of people talk,<br />

but in general they’re just showing data. In<br />

the end, the operator does all the work to<br />

understand it, interpret it, then take action.<br />

It’s not realistic to expect them to comb<br />

through all the data, interpret graphs,<br />

analyse, then diagnose, then take a solution.<br />

So, we do that for them, we diagnose,<br />

interpret, and tell the operator exactly what<br />

they need to do.”<br />


What sets Pani Digital TM apart from the rest,<br />

according to Bhadradwaj, is how it goes<br />

beyond mere visualisation by drawing upon<br />

deep domain expertise and decades of<br />

industry experience, reducing the risk of<br />

plant operations being disrupted and<br />

lessening the amount of work operators<br />

need to do.<br />

For example, Bhadradwaj shares, Pani Digital TM<br />

is working with a 6.6 million-litre-per-day<br />

(MLD) industrial desalination plant in <strong>Asia</strong> to<br />

streamline data collection and analysis.<br />

“This plant provides water to large assets,<br />

and was having issues with data – think pen<br />

and paper logs, hidden excel sheets – and<br />

they were all isolated. There was a lack of<br />

historical data available to help take them<br />

from where they were to where they should<br />

be. It was a good challenge for us to see<br />

how we could bring a plant which was quite<br />

archaic in their data approaches to something<br />

that can use AI.”<br />

He further explained, “The challenges for<br />

the plant were high OPEX, plant complexity,<br />

and plant upgrades with undetermined<br />

setpoints; the demand was lower than what<br />

they resupplied so they had to excessively<br />

shut down the plant, which caused problems<br />

with the pump and membranes. In general,<br />

the plant was facing a lack of good<br />

instrumentation, among other issues.”<br />

Since their involvement in the plant’s<br />

operations, the plant has improved its<br />

performance, and with continued use of<br />

Pani’s technology is projected to lower<br />

chemical costs by 11-15%, energy costs<br />

and consumption by 7-10%, and increase<br />

water recovery by 3-4% in reverse osmosis<br />

optimisation, as well as allow for longer<br />

equipment life and reduced risk of membrane<br />

fouling or failure.<br />

Bhadradwaj elaborated, “As far as overall<br />

operations went, we detected sensor errors<br />

leading the plant to think that they were<br />

producing more fresh water than they really<br />

were, and that other sensors had reached<br />

saturated conductivity, posing a risk in<br />

regulatory reports. Solving these problems<br />

meant major savings in time, on top of<br />

cost savings and better use of resources<br />

for the owners. All in all, this also reduced<br />

headaches and hassle for the operators.”<br />

Perhaps it is testament to Pani<br />

Digital TM ’s work and innovations that the<br />

company received a grant for $100,000<br />

(S$103,276.74) from the Sustainable<br />

Development Technology Canada (SDTC) in<br />

late 2019 – Bhadradwaj is visibly delighted<br />

when asked about this achievement.<br />

“We’re really humbled and grateful for the<br />

SDTC to believe in us, and that they chose<br />

us to be one of the five game-changing<br />

innovators, giving us this seed grant to grow.<br />

It’s great that another Canadian organisation<br />

– this organisation, the largest clean-tech<br />

fund—saw this potential in us and in the<br />

market.<br />

For Pani, this means that the company can<br />

take on more challenges and subsidise costs<br />

to adopt new customers. This has already<br />

shown great results. Apart from this, we<br />

have received other funding and resource<br />

injections which means general growth, and<br />

based on that we have already doubled our<br />

team size over the last few months, moved to a<br />

new location, and are seeing solid traction from<br />

our customers – we’re very happily surprised<br />

by the pull we’re getting from the market!”<br />

SO, WHAT’S NEXT?<br />

Besides the grant given by the SDTC, Pani<br />

Energy was also recently selected as the winner<br />

of Imagine H 2 O <strong>Asia</strong>’s demo days, an event that<br />

was sponsored by Enterprise Singapore, SUEZ,<br />

and Moya. Pitted against several of the world’s<br />

top water technology start-ups, Pani Energy<br />

prevailed to win the H 2 O Deployment Award and<br />

a $25,000 deployment grant.<br />

Bhadradwaj shares that even with these<br />

successes, the company is always looking<br />

towards bigger, better things. “We’re in our<br />

commercialisation stage right now, and<br />

the traction we’re getting and interest from<br />

customers and geographies much wider than<br />

what we initially planned for is a good sign for<br />

us. We’re expanding our team and customer<br />

base, and what’s next for us is what’s next for<br />

the industry.<br />

Over the next decade, the world bank predicts<br />

a significant gap in supply and demand of<br />

freshwater, and current research hints that<br />

a majority of this demand will be met by<br />

non-traditional treatment processes, such as<br />

desalination and wastewater re-use. We are<br />

also seeing growth in the adoption of Zero<br />

Liquid Discharge (ZLD), especially around<br />

<strong>Asia</strong>. I personally feel better knowing there are<br />

technologies out there that allow these plants<br />

to do more with less.<br />

Looking at climate from a holistic perspective,<br />

one of our lowest risk solutions in helping<br />

address climate change is increasing<br />

efficiencies of existing infrastructures. For the<br />

plants we are targeting, there is tremendous<br />

opportunity to increase efficiencies, and a<br />

software-as-a-service (SaaS) optimisation<br />

model, in comparison to large retrofits, presents<br />

low adoption barriers. With these plants being<br />

present at global scale with industries and<br />

municipalities, efficiency improvements directly<br />

benefit the Sustainable Development Goals for<br />

both clean water access and climate change.<br />

It’s a bright future for Pani, and a bright future<br />

for the industry as a whole.” WWA<br />

ON OUR RADAR 51<br />

Freshwater is becoming scarcer and more expensive, and seawater is an increasingly viable<br />

alternative to meet such demands – but for seawater reverse osmosis (SWRO) plants,<br />

biofouling remains the biggest challenge.<br />

In response to this, DuPont has launched the FILMTEC SW30XFR-400/34, a fouling-resistant<br />

SWRO element. The element was first unveiled at the International Desalination Association’s<br />

(IDA) World Congress, which took place from 20-24 October in Dubai.<br />

FILMTEC elements take system performance to higher levels by combining premium membrane<br />

performance with automated precision fabrication, and the FILMTEC SW30XFR-400/34 is<br />

designed specifically to handle biofouling in seawater desalination plants. These elements are<br />

equipped with advanced fouling-resistant and cleanability features, helping plants reduce the<br />

number of chemical cleanings required while maintaining high rejection and low energy.<br />

Biofouling occurs when bacteria present in feed water settles on the membrane surface – this<br />

creates a biofilm, which triggers frequent Clean-in-Place. In challenging water, biofouling is more<br />

prevalent and the need for frequent cleaning shortens membrane life, resulting in increased cost<br />

for the plant.<br />

Compared to the standard SW30HRLE-400, the FILMTEC SW30XFR-400/34 offers up to a<br />

40% lower pressure drop with improved performance that normalises permeate flow and salt<br />

rejection. It also offers over 33% reduction in annual chemical Clean-in-Place frequency, which<br />

translates to less downtime, more productivity and increased savings for users.<br />

“Picture a 100,000 m³/d desalination plant – the improved capabilities of FILMTEC<br />

SW30XFR-400/34 translate to total savings of $490,000 (S$661,549) annually, as well as<br />

a 5.5% decrease in water cost during the RO stage,” said Gary Gu, global technology leader,<br />

DuPont <strong>Water</strong> Solutions.<br />

Other benefits of using the FILMTEC SW30XFR-400/34 include:<br />

• Fouling-resistant design, reducing the number of required chemical cleanings by over 33%<br />

• Durable membrane chemistry, maintaining stable and high rejection despite repeated chemical<br />

cleanings<br />

• Low element differential pressure, improving system hydraulic balance<br />

• More effective and efficient cleaning of biofilm, organic compounds and scale, achieved through<br />

the widest pH range in cleaning (pH 1-13)<br />

“DuPont’s membranes are taking desalination to the next level for our customers and the<br />

industry,” remarked H.P. Nanda, global vice president and general manager of DuPont <strong>Water</strong><br />

Solutions. “We’re proud to share them with others in the industry who are committed to meeting<br />

the United Nations’ Sustainability Goal 6: ensuring the availability and sustainable management<br />

of water and sanitation for all.” WWA<br />

a monitoring system that will receive<br />

data from the equipment performing<br />

wastewater treatment and apply the data<br />

analytics algorithm and machine-learning<br />

techniques to help improve the plant’s<br />

operational efficiency.”<br />

AquaNERVA is currently deployed at<br />

UPWRP to collect and analyse realtime<br />

data from key equipment. The<br />

smart system will be able to evaluate<br />

the equipment’s condition and detect<br />

anomalies, alert operators to potential<br />

problems that could lead to failures, as<br />

well as recommend actions for repair and<br />

maintenance. Through machine-learning<br />

techniques, AquaNERVA will also learn from<br />

past equipment failures and predict future<br />

ones more effectively.<br />

UPWRP is the first such facility in Singapore<br />

to use this solution – AquaNERVA has been<br />

tested extensively, and proven successful<br />

An in-house innovation of ST Engineering,<br />

AquaNERVA effectively incorporates data<br />

analytics and machine-learning techniques to<br />

perform condition-based monitoring, predictive<br />

diagnostics and prognostics.<br />

According to Sim Chee Chong, assistant<br />

director of Marine Technology & Solutions, Ship<br />

Management & Sensemaking Systems, Marine,<br />

at ST Engineering, this can greatly improve<br />

operational efficiency.<br />

AquaNERVA equipment monitoring and control<br />

“Firstly, it prolongs the maintenance intervals<br />

due to the implementation of the conditionbased<br />

monitoring. Maintenance is performed<br />

based on condition of the equipment as<br />

opposed to a fixed maintenance schedule. This<br />

improves uptime and extends the lifespan of<br />

equipment, hence generating cost-savings.<br />

Secondly, it prevents unplanned downtime<br />

through predictive diagnostics, which is<br />

essential to any plant operations. This<br />

changes the nature of maintenance from<br />

reactive to preventive.<br />

to successfully predict imminent failures.”<br />

Challenges faced in the implementation of<br />

AquaNERVA for UPWRP included the lack of<br />

quality data.<br />

AquaNERVA feature - maintenance e-log<br />

“This is very common for implementing<br />

data analytics and machine learning,” said<br />

Sim. “Massive amounts of good quality<br />

data are needed to train the machinelearning<br />

model, so that we can ensure the<br />

model is intelligent enough to perform<br />

its tasks. We overcame these challenges<br />

by working closely with UPWRP, so that<br />

we would identify which are the areas for<br />

improvement in terms of data management,<br />

and provide advice and suggestions. This<br />

will also help them build a more robust data<br />

management centre.” WWA<br />

AQUALABO’s STAC2 is an on-line UV-Vis alert analyser for on-line water chemical quality<br />

monitoring of BOD / COD / TOC / TSS and Nitrates.<br />

Developed by Secomam, under<br />

AQUALABO, the STAC2 is the<br />

successor to the STAC1, a compact<br />

alarm system that measures the sample<br />

absorbance in specified areas of the UV<br />

spectrum and records the spectral profile of<br />

the sample as a true numerical picture of the<br />

water’s quality.<br />

The STAC2 analyser measures the<br />

absorbance of UV light over a broad range<br />

of wavelengths, providing an indication of<br />

the organic concentration in the sample.<br />

AQUALABO took the chance to introduce<br />

the STAC2 at the INDOWATER exhibition<br />

in August, where Joep Appels, manager<br />

analyser (business unit) at AQUALABO<br />

explained, “The heart of the technology is<br />

that we use light, light detection technology,<br />

but in different ways. The STAC2 uses UV<br />

light technology that go through the sample,<br />

and without any reagents or moving parts<br />

can give a result in COD and BOD where you<br />

would normally use chemical reagents to<br />

determine.”<br />

The STAC2 has the flexibility to use four<br />

different streams and combine this with up<br />

to 10 different models per sample stream.<br />

By scanning and measuring the entire<br />

absorption spectrum, the STAC2 can create<br />

a unique fingerprint from the sample<br />

analysed.<br />

The STAC2 is also able to connect to an<br />

Ethernet or WiFi network – human interface<br />

is based on an embedded webpage which<br />

users can access via the network, and<br />

allows the user to manage the configuration,<br />

status and results of the STAC2.<br />

According to Appels, challenges faced in<br />

implementing the STAC2 included a lack<br />

of legislation. “You have to work with the<br />

government, to prove that you have a more<br />

advanced and better technique, together very<br />

often with customer long-term testing so that<br />

over a period of a year or so you can show<br />

the data. But it needs time, so you cannot<br />

immediately start with selling, you need defined<br />

preferences, you need to work with research<br />

universities or institutes for that.”<br />

The STAC2 is suitable for use in various<br />

applications, including:<br />

• <strong>Wastewater</strong> treatment plants, as a follow-up<br />

for purification performance, input,<br />

discharge etc<br />

• Drinking water plants, for pumping station<br />

and tank management<br />

• Natural water sources<br />

• Processed water<br />

• River monitoring<br />

• Aquaculture<br />

AQUALABO is currently seeking to bring<br />

the STAC2 to the <strong>Asia</strong>n market, and Appels<br />

elaborated that the STAC2 would be very useful<br />

to many integrators in the market. “I think we<br />

see a lot of opportunities, the challenges in <strong>Asia</strong><br />

are big – <strong>Asia</strong> is looking for new technologies to<br />

help improve the environment.<br />

If I look to India and China, these are already<br />

the biggest markets in the world, but the<br />

Philippines and Indonesia are also looking at<br />

a tremendous challenge: The economy and<br />

industry are growing, which puts more pressure<br />

on the environment, but tourism is also growing<br />

and tourists will come if they have a nice beach,<br />

clean environment, and access to clean water.<br />

If the government is supporting this, they have<br />

a better environment for their own people and<br />

create a clean industry, and industries are<br />

capable of treating the wastewater.” WWA<br />

Lifting and screenings handling can also<br />

be conducted outside the channel, which<br />

increases options for additional washing<br />

and dewatering, according to individual<br />

applications, said Bambridge.<br />

The robustly engineered horizontal in-channel<br />

rotary drum screening technology is designed<br />

to simplify fine screening processes, and save<br />

installation and operational costs, said CST<br />

<strong>Wastewater</strong> Solutions’ Managing Director<br />

Michael Bambridge.<br />

The low-maintenance high-quality stainlesssteel<br />

design features in-channel technology for<br />

low fluid head loss at peak flows to increase<br />

solids removal efficiency as compared with<br />

typical screening at the diverse wastewater<br />

treatment plants in the region.<br />

“Advantages of this technology when dealing<br />

with fine screening of larger flows (5mm or<br />

finer screening on flows up to 2000 l/sec flow)<br />

include mechanical simplicity, self-cleaning<br />

and high efficiency screening for reduced<br />

maintenance and cheaper whole-of-life costs<br />

compared with other types of screens, such<br />

as band and inclined drum screen designs, for<br />

example,” said Bambridge.<br />

“These are very important considerations<br />

when dealing with plants that may be remote<br />

from immediate technical support where<br />

ongoing reliability and simplicity of cleaning<br />

are important from engineering and<br />

environmental perspectives,” said<br />

Bambridge, whose international and<br />

regional experience includes both<br />

municipal and industrial WWTP<br />

engineering and green energy<br />

initiatives in partnership with local<br />

suppliers. CST <strong>Wastewater</strong> Solutions<br />

has a number of successful screening<br />

applications in service in SE <strong>Asia</strong>, including<br />

food and beverage and paper industry<br />

applications, for which the in-channel rotary<br />

CST <strong>Wastewater</strong> Solutions introduces the<br />

advanced wastewater fine screening technology<br />

to Southeast <strong>Asia</strong><br />

drum technology is also particularly<br />

suitable.<br />


Key to this functionality is the configuration<br />

of the design, in which the screening drum<br />

is installed horizontally semi-submerged<br />

in line with the incoming wastewater. The<br />

plate at the back of the drum directs flow<br />

radially through the mesh to optimise solids<br />

separation and self-cleaning.<br />

The rotary drum is manufactured from<br />

either self-cleaning wedge wire for primary<br />

screening, or perforated plate for fine premembrane<br />

bioreactor (pre-MBR) screening.<br />

It is washed by a system of spray nozzles at<br />

a moderate pressure.<br />

An internal hopper collects the screenings,<br />

which are flumed out to the integral lifting<br />

and dewatering screw, to efficiently dewater<br />

and reduce screenings volume. The lifting<br />

screw is shaftless to avoid any blockages,<br />

Functional layout of CST<br />

<strong>Wastewater</strong> Solutions’ In-Channel<br />

Rotary Drum technology<br />

“Screening and the solids lifting and<br />

dewatering are separate operations, using<br />

high efficiency screening technology to<br />

convert the high-flow, low-solids wastewater<br />

to low-flow, high-solids dewatering. Separate<br />

screening and lifting equipment make access<br />

simpler for more cost-effective housekeeping<br />

and maintenance for lower whole-of-life<br />

costs,” he explained. WWA<br />


DESIGN<br />

• Lowers operating depth and range<br />

to reduce average screen velocities for<br />

higher removal efficiencies, and easier<br />

cleaning than alternative screens.<br />

• Increases available open area for equivalent<br />

operating depth, which enhances<br />

functionality.<br />

• Robust construction tailored to local<br />

conditions. The one-piece, closed drum is<br />

fully assembled in a frame for installation into<br />

a channel. It incorporates a simple, long-life,<br />

robust inlet seal that can be replaced without<br />

removing all equipment from the channel.<br />

• All parts subject to routine maintenance are<br />

located above the sewage flow,<br />

again simplifying maintenance and<br />

reducing OH&S issues.<br />

• Screening and lifting screw equipment<br />

are proven, simple and robust technologies.<br />

No bearings or other high maintenance<br />

moving parts are located in the wastewater.<br />

Housekeeping and servicing are conducted<br />

from above the flow channel. No mechanical<br />

devices are used inside the screen drum.<br />

• Open entry for clean collection of solids<br />

— no rag wrapping, reducing maintenance<br />

and OH&S issues. The screen zone of the<br />

lifting screw incorporates a washing<br />

The VEGAPULS 31 for non-contact level<br />

measurement in simple applications<br />

VEGA has extended its VEGAPULS<br />

family with a new instrument series for<br />

continuous level measurement – this<br />

new series is based on 80-GHz technology,<br />

and features a specially-developed radarlevel<br />

microchip.<br />

Its suitable applications include the water<br />

and wastewater sector or in auxiliary process<br />

loops in process automation.<br />





Due to their physical measuring principle,<br />

ultrasonic sensors are easily affected by<br />

ambient conditions. For example, strong<br />

wind, rain, or fog can all dampen sound<br />

waves, and restrict measuring range,<br />

affecting measurement accuracy. Radar<br />

sensors, however, are not affected by<br />

temperature or pressure fluctuations,<br />

vapours, gases or vacuum and can deliver<br />

accurate readings under all conditions.<br />

In the water and wastewater sector, level<br />

measuring systems are regularly exposed<br />

to the adversities of nature. One example is<br />

flow rate measurement in the main sewers<br />

leading to the sewage treatment plant.<br />

Compared to ultrasonics, the new radar<br />

sensors have a higher accuracy and are<br />

independent of environmental influences.<br />

This enables precise measurement and thus<br />

a more reliable calculation of wastewater<br />

flows.<br />

The new compact radar sensor can also<br />

be used for trustworthy monitoring of river<br />

and flood levels. Its measured values are<br />

an important prerequisite for being able to<br />

react quickly and correctly in the event of<br />

flooding. Radar sensors can monitor river<br />

levels without being affected by temperature<br />

fluctuations, such as those caused by<br />

strong solar radiation. Even at a distance of<br />

30 metres from the water surface, a radar<br />

transmitter delivers level readings accurate<br />

to the millimetre.<br />





Sensors constantly struggle with the<br />

problem of build-up at many level measuring<br />

sites. In the case of ultrasonic sensors,<br />

for example, contamination on the sensor<br />

face greatly affects the reliability of the<br />

measurement signal and enlarges the dead<br />

zone. The situation is different with radar<br />

technology. Optimised signal processing<br />

enables radar sensors to suppress<br />

interference caused by build-up on their<br />

antenna system. On top of that, radar<br />

technology is generally more immune to the<br />

effects of dirt and build-up and does not<br />

have to be cleaned.<br />

<strong>January</strong> / <strong>February</strong> <strong>2020</strong> • waterwastewaterasia.com

ON OUR RADAR 57<br />

The VEGAPULS C21, a wired radar sensor for<br />

continuous level measurement<br />





Thanks to 80-GHz technology, the radar<br />

beam can be aimed at the measured<br />

medium with pinpoint accuracy. As a result,<br />

narrow shafts or deposits on vessel walls<br />

or internals such as pipes or pumps cannot<br />

generate interfering signals. So in contrast<br />

to ultrasonic, radar needs no false signal<br />

suppression. Even condensation and dirt do<br />

not bother the new VEGAPULS.<br />

Compact radar sensors without dead zone<br />

deliver reliable level values in small vessels<br />

These new sensors have no dead zone, and<br />

thus it is possible to measure right up to<br />

the top of the container. Typical areas of<br />

application are therefore emergency power<br />

generators or storage and buffer tanks,<br />

among others.<br />

Emergency power generators are an<br />

important precautionary measure to keep<br />

complex systems operating during a power<br />

failure. The fuel for generators is often<br />

stored in a main tank and in day tanks.<br />

To ensure that there is always enough<br />

fuel on hand, the levels in the tanks are<br />

continuously monitored. The new compact<br />

sensor delivers accurate measuring results,<br />

even in small tanks and media with poor<br />

reflective properties.<br />

Storage and buffer tanks guarantee<br />

the supply of raw materials for ongoing<br />

processes. The new radar sensors can<br />

exploit their strengths here, as they can<br />

be installed in very confined spaces and<br />

small process fittings. Even if the medium<br />

generates gases, the sensors remain<br />

unaffected and deliver reliable measuring<br />

results. In addition, they have an Ex<br />

approval for flammable media. So it makes<br />

them highly versatile for use in a wide range<br />

of applications.<br />

The new instrument series is available in<br />

two versions: as a compact model with<br />

cable connection housing and as a standard<br />

model with fixed cable connection (IP68).<br />

The sensors can be easily and safely<br />

adjusted via Bluetooth with a smartphone<br />

or tablet – ideal for harsh environments or<br />

hazardous areas. WWA<br />

In the wastewater industry, sewage<br />

treatment plants are one of the main<br />

application areas, for example in mechanical<br />

screening, where floating matter is<br />

removed. Measurement of the water level<br />

difference between each side of the screen<br />

or sieve is used to determine the degree<br />

of contamination and control the cleaning<br />

cycles. In such outdoor applications,<br />

whether in rain or intense sunlight, the<br />

new radar sensors perform with high<br />

accuracy.<br />

Another example is silo level measurement<br />

of lime, which is used to stabilise the<br />

effluent pH value. The radar sensors<br />

measure reliably, with no effect from the<br />

huge amounts of dust generated during<br />

the filling process. Thanks to strong signal<br />

focusing, build-up and deposits on the<br />

container wall or on the sensor itself are no<br />

problem.<br />

How China<br />

combats water<br />

shortage<br />

As the Yellow River conveys large quantities of<br />

sand, the pumps will be provided with a special<br />

abrasion-resistant coating.<br />

According to the United Nations’<br />

latest estimates, the earth will<br />

have a population of 9.8 billion by<br />

2050. And today there are already some<br />

2.7 billion people who are confronted<br />

with water scarcity for at least a month<br />

of the year. The World Resource Institute<br />

anticipates that, as a result of the economic<br />

and population development as well as<br />

various climate change scenarios, a total<br />

of 33 countries over all continents will<br />

face a shortage of water by 2040. With 14<br />

countries on this list, <strong>Asia</strong> is the continent<br />

that is most severely affected. As the <strong>Asia</strong>n<br />

country with the largest land area and<br />

largest population, China has already been<br />

working on sustainably optimising its water<br />

supply for several years now.<br />

China is facing the difficult situation of<br />

having to provide for 20% of the world’s<br />

population with only just over 7% of the<br />

global water resources. This situation is<br />

aggravated by the fact that 80% of Chinese<br />

water sources are in the southern part of<br />

the country, but 64% of the agricultural<br />

land is in the northern part, where<br />

more than 50% of the population live.<br />

Additionally, 85% of China’s coal reserves<br />

are hidden in the arid northern provinces<br />

and mining this coal requires large<br />

quantities of water.<br />


In order to solve this problem, China started<br />

a huge water supply project in 2002. The<br />

South-North <strong>Water</strong> Transfer Project is to<br />

transport 44.8 billion cubic metres of water<br />

from the wet south to the dry north of the<br />

country every year from 2050. The essential<br />

basis for this is provided by the three main<br />

routes — eastern, central, and western —<br />

that are to ensure a sustainable water supply<br />

in northern China in the future.<br />

In addition to the country’s longest river,<br />

the Yangtze, which divides China into a<br />

northern and southern part, the Yellow River,<br />

which is the country’s second longest river,<br />

plays a significant role in feeding these<br />

canals. Its name derives from the yellow<br />

mud and sediments that it picks up in the<br />

Shaanxi Loess plateau. Due to the<br />

high concentration of sludge and<br />

sediment in its bed, the river tends<br />

to burst its banks. And yet, the<br />

“River of Sorrow”, as it is also<br />

called because of the damaging<br />

effects of its floods, is a lifeline<br />

for northern China. It<br />

supplies water to<br />

155 million people — 12% of the Chinese<br />

population — and irrigates 18 million<br />

hectares or 15% of the agricultural land in<br />

China.<br />



The Xiaolangdi hydropower station on the<br />

Yellow River was completed in year 2000.<br />

It is the country’s second largest multifunctional<br />

plant after the Three Gorges<br />

Dam on the Yangtze River. Comprising of<br />

underground power plants, sludge discharge<br />

channels, and a dam that is 1,317 metres<br />

long and 154 metres high, it performs<br />

several tasks, such as flood protection,<br />

industrial and urban water supply, and<br />

electric power generation of 5.1 billion kWh<br />

per year.<br />

With a capacity of 12.8 cubic kilometres, the<br />

dam — known as the Xiaolangdi Reservoir<br />

— has served as a water supply source for<br />

the dry north of the country ever since the<br />

plant was completed. In order to expand<br />

this source of irrigation, the water can now<br />

be taken directly from the reservoir fed<br />

by water from the Yellow River, which was<br />

used to irrigate the dry, northerly regions<br />

of Taiyuan, Pingsuo, and Datong in the past.<br />

This is a sub-project of the central route in<br />

the South-North <strong>Water</strong> Transfer Project.<br />

The Shanxi Xiaolangdi Yellow River Diversion<br />

Project is based on two reservoirs, several<br />

tunnels, subsurface channels, pumping<br />

stations, pipelines, and aqueducts and is<br />

designed to divert 247 million cubic metres<br />

of water annually. Irrigation will account<br />

for 116 million cubic metres, industrial<br />

and urban water demand for another 116<br />

million cubic metres, and 15 million cubic<br />

metres will be used for ecological purposes.<br />

For this, water from the Yellow River will<br />

be transported to a subsurface pumping<br />

station through a six-kilometre-long tunnel.<br />

The pumping station is equipped with four<br />

hydraulic machines that pump the water<br />

over a distance of roughly 60 kilometres to<br />

an artificial lake in the northwestern part of<br />

Shanxi Province.<br />


As the best candidate in the call-for-tenders<br />

assessment process concerning project<br />

requirements and detailed proof thereof,<br />

ANDRITZ was awarded the order to deliver<br />

the four pumps for the subsurface station of<br />

the Shanxi Xiaolangdi Yellow River Diversion<br />

Project. The international technology group<br />

is by no means a newcomer in China.<br />

ANDRITZ ventured its first steps in this<br />

country more than 20 years ago. The<br />

subsidiary, ANDRITZ (China) Ltd., which<br />

was established in 2002, has a total of<br />

over 1,600 employees based in Beijing,<br />

Shanghai, Chengdu, and Wuxi, as well as<br />

in the production facilities in Foshan and<br />

Chengdu. Besides executing various orders<br />

for pulp and paper mills or the recent award<br />

of an order to supply pump turbines, motor<br />

generators, and auxiliary equipment for the<br />

ZhenAn pumped storage power station,<br />

ANDRITZ also provided assistance in other<br />

sub-projects of the South-North <strong>Water</strong><br />

Transfer Project in the past. At the Hui Nan<br />

Zhuang station, eight ANDRITZ horizontal,<br />

double-suction split-case pumps supply<br />

drinking water to the Chinese capital of<br />

Beijing, 60 kilometres away. Another 11<br />

ANDRITZ pumps of the same type are<br />

installed in two stations pumping 200,000<br />

cubic metres of water from the Yellow River<br />

to the city of Hohhot, the capital of the<br />

Inner Mongolia autonomous region.<br />

ANDRITZ is to manufacture and supply four<br />

two-stage vertical volute pumps for the<br />

Shanxi Xiaolangdi Yellow River Diversion<br />

Project. These pumps will be customised to<br />

meet the respective project requirements<br />

and will thus be the ideal water transport<br />

pumps for irrigation and drainage as well<br />

as for the supply of drinking and industrial<br />

water, each of them achieving a flow rate of<br />

five cubic meters per second over a head of<br />

236 metres at an output of 13 megawatts.<br />

Their appeal especially lies in the efficiency<br />

of more than 91%. As the Yellow River<br />

conveys large quantities of sand, the pumps<br />

will be provided with a special abrasionresistant<br />

coating.<br />

The hydraulic dimensioning and design of<br />

the volute casing depends on the specific<br />

output characteristics. Optimum flow in<br />

the volute is achieved due to its individual<br />

shaping, which also guarantees a high level<br />

of efficiency. By varying the trailing edge,<br />

high-precision adjustments can be made to<br />

the desired duty points. The volute casing is<br />

designed as a metal volute. This is a welded<br />

structure consisting of several segments,<br />

double-suction split-case pumps supply drinking water to<br />

which optionally can be embedded in concrete.<br />

A solution without concrete lends itself to the<br />

Shanxi Xiaolangdi Yellow River Diversion Project<br />

because higher delivery heads are necessary,<br />

which, due to the strength requirements,<br />

cannot be handled with a concrete volute.<br />

The guide vane mechanism is opened and<br />

closed in a continuous process. The guide<br />

vanes are individually connected to the<br />

operating ring by means of articulated<br />

levers. This ring is actuated via hydraulic<br />

cylinders and rotates the guide vanes into the<br />

desired position. A guide vane mechanism<br />

is an emergency closing element in case of<br />

difficulties with the electric power supply, but<br />

it can also be closed to keep the power input<br />

to a minimum if synchronous motors are used<br />

during start-up. By closing the guide vane<br />

mechanism it is as well possible to start up<br />

the pump when the pressure pipe is full. This<br />

guarantees a short start-up time with minimum<br />

power input.<br />

Delivery, installation, and start-up of the<br />

ANDRITZ pumps are scheduled to take place in<br />

about two years. This will be another successful<br />

step for China towards obtaining a sustainable<br />

water supply in the north of the country. WWA<br />

technologies are required, and ASIAWATER<br />

<strong>2020</strong> plays an important role and acts as<br />

a platform for all water industry players in<br />

providing a unique opportunity to explore,<br />

share and showcase the latest solutions<br />

and technologies,” said Malaysia’s Prime<br />

Minister, Tun Dr. Mahathir Bin Mohamad.<br />

There will be three key themes for the<br />

11 th edition of ASIAWATER’s free-to-attend<br />

conference and seminars, which includes<br />

Policy & Governance, Financial & Technical<br />

Sustainability, and <strong>Water</strong> Resource<br />

Management.<br />

Dato’ Teo Yen Hua, Advisor of ASEAN <strong>Water</strong><br />

Series said, “I believe with the impressive<br />

lineup of international and regional speakers<br />

sharing and presenting, it will certainly<br />

benefit not just the private sector but also<br />

the Federal and State Governments of <strong>Asia</strong>”.<br />

ASIAWATER <strong>2020</strong> will be the best platform for<br />

open and constructive dialogues for players<br />

from within ASEAN and the rest of the world<br />

focusing solely on water and wastewater issues<br />

within the region.<br />

“The Philippine <strong>Water</strong> Works Association<br />

(PWWA) hopes to work with other<br />

organisations in the region to stimulate the<br />

growth of the water industry and sharing best<br />

practices and solutions to water-related crisis<br />

throughout ASEAN, and I believe ASIAWATER<br />

<strong>2020</strong> is the platform for this,” said the<br />

President of PWWA, ATTY. Vicente M. Joyas.<br />

Mrs. Eliane van Doorn, Regional Director<br />

Business Development – ASEAN, Informa<br />

Markets commented: “ASIAWATER has always<br />

been updating its content from year to year as<br />

the 11 th edition will be seeing fresh and new<br />

content. Besides the usual conference and<br />

seminars, ASIAWATER <strong>2020</strong> will have the new<br />

WATER TALKS where thought leaders in the field<br />

The MENA <strong>Water</strong> Summit will be held<br />

under the patronage of the ‘Ministry<br />

of Electricity and <strong>Water</strong> – Kuwait’,<br />

which will focus on developing effective plans<br />

to establish advanced water management<br />

techniques. This is to cope with Kuwait’s<br />

2035 vision and current water situation in the<br />

MENA region while ensuring water security<br />

and sustainability for all. With an increasing<br />

demand for water owing to growing<br />

population and incessant urbanisation, water<br />

authorities and utility companies will need<br />

to augment their supply sources; discuss<br />

regulatory frameworks; innovate financing<br />

models and water treatment options as well<br />

as manage water demand with advanced<br />

technologies so as to address water security<br />

challenges of the 21 st century.<br />

Kuwait is shifting to innovative water<br />

treatment and renewable desalination<br />

technology as more than 95% of its potable<br />

water comes from desalination — an energyintensive<br />

technology burning fuels for<br />

drinking water and treatment of wastewater<br />

for domestic and irrigation purposes.<br />

discussions on policies and actionable<br />

ideas, which utilities can adapt to meet<br />

their commitment towards fostering<br />

innovative solutions and sustainable water<br />

management. It will also provide the<br />

opportunity to share success stories and<br />

explore ways to collectively respond to<br />

challenges.<br />

The Summit will bring together water<br />

and municipal authorities, regulators,<br />

sustainability leaders, international NGOs,<br />

water consultants, water and wastewater<br />

construction companies, academia,<br />

water management experts and solution<br />

providers who will discuss various strategies<br />

to encourage sustainability of water<br />

management and implementation of water<br />

stewardship standards. The Summit will<br />

offer unparalleled opportunities to network<br />

with peers and explore new products,<br />

technologies, and services.<br />

The Summit will be inaugurated by<br />

Mohammed Boshhari, Under Secretary -<br />

Ministry of Electricity & <strong>Water</strong>. WWA<br />

The International <strong>Water</strong> Industry<br />

Exhibition in Myanmar recently<br />

staged its 6 th successful trade show in<br />

Yangon. Held at the Myanmar Expo Hall, from<br />

28 to 30 November 2019, the Expo attracted<br />

trade visitors from all over the country,<br />

making this event the focal gathering point<br />

for Myanmar’s entire water and wastewater<br />

industry.<br />

Co-located with MYANBUILD and<br />

MYANENERGY 2019, the International<br />

Exhibition featured the latest products and<br />

solutions designed to improve Myanmar’s<br />

production, supply and treatment of its<br />

The Expo included Pavilions representing Singapore, Taiwan,<br />

China, Vietnam, Thailand, India, Malaysia and Italy<br />

water and wastewater industries. The Expo<br />

included Pavilions representing Singapore,<br />

Taiwan, China, Vietnam, Thailand, India,<br />

Malaysia and Italy.<br />

Companies and brands that participated in<br />

the show included MW Aqua Solution Co.,<br />

Ltd, Mitsubishi Chemical Aqua Solution Co.,<br />

Ltd, Wa Min <strong>Water</strong> Co., Ltd, Kuaray <strong>Asia</strong><br />

Pacific Pte Ltd, Pipe Line Process & System<br />

Pte Ltd, Torishima Service Solutions <strong>Asia</strong> Pte<br />

Ltd, and Aqua Nishihara Corporation Limited.<br />

MYANWATER provided exhibitors and visitors<br />

with the ideal platform to find emerging<br />

water and wastewater treatment solutions,<br />

the latest technologies and instruments for<br />

the water management industry, source<br />

for new suppliers and distributors, build<br />

strategic business partnerships, network<br />

with major decision makers and industry<br />

peers, explore new business opportunities,<br />

and get updated on the latest trends and<br />

developments shaping the sector.<br />

Myanmar has grown by leaps and<br />

bounds over the past few years. Since its<br />

liberalisation in 2011, the Government<br />

has shifted from an authoritarian military<br />

rule to a democratic system, improving the<br />

country’s political and economic scenario.<br />

Aiming to create new growth and investment<br />

opportunities for the country’s main<br />

industries, significant efforts have been made<br />

to improve Myanmar’s business environment,<br />

in terms of dealing with permits, starting a<br />

business and enforcing contracts.<br />

Furthermore, with Yangon’s population<br />

estimated to grow by three million within<br />

the next 10 years, major improvements<br />

need to be made to ensure the management<br />

and treatment of Myanmar’s water and<br />

wastewater industries are carried out<br />

effectively and sustainably. This is sure<br />

to open up opportunities for local and<br />

foreign companies to capitalise on. Demand<br />

for products and services related to<br />

microfiltration, ultrafiltration, water softening,<br />

pumps, valves, chlorinators for water/<br />

wastewater systems and many more sub<br />

sectors of the industry are set to increase<br />

over the years as Myanmar works to improve<br />

its treatment standards and management<br />

strategies.<br />

The trade show is set to return in <strong>2020</strong> to<br />

host its 7 th edition, from 19 to 21 November,<br />

at the Myanmar Expo Hall in Yangon,<br />
