The answer: the glass is always full. It is filled

half with water, and half with air. Similarly, as

individual players in the water industry might

not be sufficient to solving the most immediate

issues of this day and age, organisations

from the private, public, and academia

sector should come together to create a

comprehensive plan for the rocky years ahead.

Where one falls short in certain aspects,

others must step forward to fill in possible


It goes without saying that 2022 has seen

significant highs and lows for the water

industry. From recording-breaking heatwaves

and extended droughts, to the emergence

of a new normal in a post-pandemic realm,

companies, utilities and governments around

the world have dipped their toes into the

uncharted waters of dealing with a rapidly

changing world. While we continue to navigate

this unpredictable realm, it has become

evident that working together towards a

common goal is the only way forward.

Take Veolia Water Technologies, for example:

in collaboration with Mölnlycke, a medical

products provider, the company has

formulated sustainable wastewater treatment

solutions for their recently inaugurated plant

in Kulim, Malaysia. By taking stock of the

demands in medical glove manufacturing

and keeping abreast of sustainable goals in

the country, Veolia was able to integrate a

treatment designed to further the company’s

green targets.

Similarly, Grundfos recently signed a

memorandum of understanding with

Singapore Polytechnic to develop water and

energy efficient solutions across various

industries. The former will utilise its experience

in smart technology to bring sustainable

savings, while the latter will draw relevant

networks between academia and industry.

Altogether, this partnership will enhance the

grid of sustainable models, allowing more

companies in Singapore to benefit from a

green transformation.

Elsewhere, India must juggle the needs of

rising manufacturing industry and ensure

its people have access to clean, unpolluted

water. Enter Energy Recovery, whose, as

their names suggests, have enabled the

country to reap the benefits of industrial

wastewater treatment at low cost. With this,

India is one step closer to reducing water

pollution and enhancing the quality of life of

her people.

Regardless of nation, regardless of

industry, everyone plays an important

role in securing the future of our water

resources. As ice caps are melting at an

unprecedented pace in the most extreme

corners of the globe, while lakes are

shrinking in others, the path towards a

more sustainable road is paved by all

parties involved. And here at Water &

Wastewater Asia, we will continue to bring

you provoking stories from all corners of

the industry, in hopes that it can inspire our

readers to take the charge forward towards

a better, greener future.

In the final issue of this year, let us reflect

on the progress we made this past year,

and look boldly into the future ahead. The

glass is, after all, always full.

Xylem Water Solutions Singapore

and Gross-Wen Technologies (GWT)

have announced a memorandum of

understanding (MoU) for a new joint

R&D project to deploy algae-based

wastewater treatment solutions in

Singapore. The project will focus

on the development of GWT’s

existing revolving algal biofilm

(RAB) technology, an algae-based

wastewater treatment solution that

promotes nutrient recovery while

reducing the carbon footprint of water


The project will feature GWT’s algaebased

treatment of anaerobic digestor

(AD) effluent for carbon footprint

reduction and nutrient recovery. This

includes atmospheric CO2 capture

by algae, low-energy nitrogen and

NX Filtration, a provider of direct water

nanofiltration technology, has announced

its participation in the European innovation

project LIFE PRISTINE. The project’s

objective is to eliminate emerging

contaminants in the integral water cycle,

which is one measure to promote alternative

water resources in the face of water scarcity.

The LIFE PRISTINE project has a budget

of €4m and is coordinated by Acciona, the

Spanish sustainable infrastructure solutions

group. Other project partners include Eurecat,

Xylem Services, the Regional Entity for

Wastewater Sanitation and Treatment of the

Murcia Region (ESAMUR) and the water utility

provider Bilbao Bizkaia Water Consortium

(CABB). The project hopes to combine water

treatment processes, such as NX Filtration’s

hollow fibre nanofiltration membranes, with

artificial intelligence (AI)-based digital tools to

develop a solution that removes the emerging


The project was launched in light of various

forums being alerted to the urgent need to

take steps in protecting water resources.

Such an outcome can be achieved through

reducing water consumption, but also by

promoting alternative resources and reuse.

One key issue that has been raised in efforts

to encourage water reuse is the presence

of pollutants and microplastics in water

supplies. These substances of anthropogenic

origin are difficult to eliminate when using

existing treatment systems and they may end

up in seas and rivers, or even enter the food

chain. Their presence may create hazards.

There is thus an increasing emphasis on

regulating the use of these substances and

developing solutions to remove them from the


LIFE PRISTINE thus aims to eliminate up to

80% of emerging pollutants in the endto-end

water cycle, particularly per and

polyfluoroalkyl (PFAS) substances. These

are typically found in flame retardants,

pesticides, pharmaceutical and personal

care products, toxins microplastics and

genes of microorganisms that are resistant

to antibiotics. The project aims to strengthen

the existing legislation and promote the reuse

of water with the highest possible quality and

safety standards.

The PRISTINE solution involves the

processes of adsorption, nanofiltration and

advanced oxidation using virtual sensors,

process modelling and decision-making

support tools. The machine is said to be

capable of reducing emerging pollutants from

water sources and wastewater effluent. The

PRISTINE project is set to be demonstrated

in a representative operating environment:

namely, the secondary effluent of a treatment

plant in Murcia, Spain, and supporting

drinking water pre-treatment in the Bilbao

Wavin has acquired Dutch start-up

MetroPolder, against the backdrop of

increasingly extreme weather events and long

periods of drought that have been affecting

the liveability of cities around the world.

With the acquisition, Wavin is expected to

incorporate MetroPolder’s knowledge to

close the water cycle in cities and make cities


MetroPolder has developed a technology

to capture water on roofs and reuse it for

cooling, irrigation and recycling. The bluegreen

roofs are equipped with a buffer

system, an internet-connected valve and

an online dashboard. The valves sensors

and rain radars control the water level and

discharge real-time. This smart connection

enables dynamic water storage. The

technology has been implemented in projects

over several locations worldwide, including

the Netherlands, Guatemala, France the UK

and US.

Friso Klapwijk, CEO of MetroPolder said:

“Wavin sees rainwater as a resource, not a

problem. That’s where we found each other.

We want to make cities future-proof, by

applying smart water management. Think

of reusing rainwater for for cooling cities to

combat heat stress. We are pleased and

proud to be part of the Wavin family from now


Maarten Roef, CEO of Wavin, said: “The

green/blue roof solution of MetroPolder

is a proven successful, international,

application that puts Wavin as a company in

an even better position to make cities more

climate resilient. Supplemented with the

knowledge and expertise of MetroPolder,

we are convinced that we will succeed in

getting more and more cities to look at the

applications of water differently. Because the

opportunities are plentiful.”




Watson Marlow Fluid Technology Solutions

(WMFTS) has helped with a revision of the

Water Industry Mechanical & Electrical

Specifications (WIMES), opening up

peristaltic pumps to more potential

customers in the UK water industry.

Peristaltic pumps, such as WMFTS’ range

of Qdos chemical metering pumps for water

and wastewater treatment applications,

had not previously had the benefits of their

technology explained in the specifications.

The revised WIMES now contains

comprehensive dosing pump specifications,

with a number of the benefits of peristaltic

pumps now more apparent and explicitly

covered in the latest version.

WIMES is a collaborative project managed

by the Pump Centre, aimed at providing

common mechanical and electrical

specifications for the UK water industry.

Seventeen of the UK’s largest water

companies are involved in WIMES, which

enables them to procure equipment which

is fit for purpose and provides the lowest

lifecycle costs at a competitive purchase


The intention of WIMES is that the

specifications should be unambiguous and

allow individual suppliers to compete on

an equal footing, so buyers can accurately

compare and contrast suppliers.

Dale Kavanagh, industrial sales & business

development manager at WMFTS UK, said:

“The specification has been rewritten so

there is more detail about peristaltic pumps,

and their benefits compared to other pump

types. It is a huge result and has helped

develop the business this year.

“For the last two years Watson Marlow have

been working hard to ensure that the latest

version of the specifications would have a

fairer balance, showing the advantages of

WMFTS Qdos 60 and

30 peristaltic pumps

are now included in

the Water Industry

Mechanical & Electrical

Specifications (WIMES)

peristaltic pump technology. This ongoing

work has resulted in large orders from several

water companies in England.

“Watson-Marlow were able to get a seat at the

table and collaborated with water regulators,

putting the case forward on why peristaltic

pumps are beneficial. The success was a

result of a lot of hard work, in particular from

sales skills training manager Bruce Quilter

and former UK industrial sales engineer Eddie



WMFTS’ Qdos range of peristaltic pumps can

handle flow rates from 0.1 to 2,000 megalitres

a minute at pressures up to 7 bar as well

as offering repeatable chemical metering

accuracy of ±1%.

With a Qdos pump, the flow remains the same

at any pressure, providing greater dosing

control and leading to measurable chemical

and energy savings — a key difference to

other equipment on the market. The low

maintenance design also means process

uptime is maximised with no-tools, and quick

and easy pumphead replacement in situ.

A reverse function enables the operator to

drain the line before maintenance and, once

in operation, there is an integral leak detector

to eliminate the risk of exposure to chemicals.

Integration of the Qdos pump range is easier

than traditional dosing pump types as they

eliminate the need for foot valves, strainers,

degassing valves and loading valves, along

with all the relevant joints, simplifying

maintenance and enabling dosing skid

manufacturers to reduce the size of their


Roger Marlow, principal consultant at the

Pump Centre, commented on the more

comprehensive dosing pump specification

in the updated WIMES: “Water managers

and engineers of large water infrastructure

projects are looking to alternative pumping

technologies for many reasons. The

landscape of chemical metering pump

manufacturing and innovation in the water

industry is changing and it is important for

WIMES documents to reflect that.

“It has been a very positive experience

working with Watson-Marlow and we will

continue the collaboration between all parties

in the future.”

Reflecting on the current landscape of

chemical dosing equipment, Kavanagh

said: “The scale of the rollout of new

equipment makes now an ideal time for

utilities to consider the whole-life benefit of

the chemical dosing equipment they select.

As such, it is believed that Qdos pumps an

ideal solution to meet companies’ water

management challenges.”

Develey Senf & Feinkost, an international

manufacturer of mustard, sauces and

dressings, commissioned Wehrle in March

2021 with the design and implementation

of a wastewater treatment plant with biogas

generation. Just one year later, in the summer

of 2022, the biological commissioning of the

industrial water treatment plant took place

at 100% capacity at the company’s largest

German production site in Dingolfing.

The Wehrle plant reduces the wastewater

pollution load in such a way that the discharge

values fixed by local authorities for indirect

discharge into the downstream municipal

sewage treatment plant are safely fulfilled.

The industrial wastewater treatment plant is

also an example for the synergetic integration

of modern environmental technology and

supports the customer’s overall sustainability

initiative by reducing production emissions.

Wehrle worked together with their customer

to develop an overall concept, including

sophisticated wastewater treatment and

reliable purification of the water during peak

loads in accordance with official requirements.

Furthermore, the integrated biogas generation

of the wastewater treatment plant together

with a modern combined heat and power

plant allows the direct conversion of the

generated biogas into electricity, which can

be used on site. The used technology is the

anaerobic high-performance BIODIGAT SB

process. With its three-phase separation

system incorporating highly efficient biogas

utilisation as well as heat pump technology

with maximised overall energy efficiencies, the

process meets all customer requirements.

The successful commissioning of the new

wastewater treatment plant was completed

almost on time, despite the difficult conditions

caused by the pandemic. The capacity was

reportedly at 100%, four weeks after inoculation

of the plant with biomass. The cleaning

result and the gas yield showed an increase

of approximately 20-30% compared to the

expected values. Intelligent control technology

enables continuous operation of the biology

and the combined heat and power plant 24/7.

Mr Reiter, technical director of Develey in

Dingolfing, was satisfied: “The robustness of

the biological process has clearly exceeded our

expectations. The high-performance system

reliably purifies our wastewater, which varies

greatly in quantity and quality, in continuous

operation. In fact, the biogas production is

so good that we are considering another

combined heat and power plant for electricity


With this project, Wehrle claims that it has

expanded its references for anaerobic

wastewater treatment and showed its reliability

as partner in the field of environmental

technology. “We are proud to be part of this

innovative and future-oriented project as an

important system supplier and to be able to

support the customer in its long-standing

claim to sustainable operation with innovative

products, clever engineering, drive and on-time

implementation,” said Frank Natau, business

development, water processes at Wehrle.





The latest version of Probit’s asset

investment manager (AIM) software aims

to help water companies in England and

Wales save time and cost in planning

works to optimise geographical synergies.

AIM4 also makes web service interfacing

and more localised analysis available to

water companies and other organisations

managing large asset bases.

AIM4 is said to have set a precedent for

analysing water and wastewater assets

together. Historically, water companies

that manage both water and wastewater

infrastructure were unable to do so, as

software with the capacity to process such

vast numbers of assets was not available.

This meant work stream management

teams were not working collaboratively and

modelling was siloed.

Increasing demand for cost efficiencies

in investment programmes means asset

management challenges are being given

greater strategic importance and becoming

more complex. Ageing infrastructure,

climate change, increasing regulation, and a

growing population can all impact on asset



Reflecting on the advances of AIM4, Philip

Jonkergouw, managing director at Probit,

said: “The biggest improvements have

been to functionality, optimisation set-up

capability, and adaptability. AIM4’s greatest

strength lies in its ability to respond to the

unknown and develop accordingly.

“AIM4 has a high level of adaptability and

flexibility when clients are facing new

requirements, especially during water

utility price reviews or asset management

modelling transitions. As a result, it can

now be used to answer more and more

complicated questions for clients.”

Using the AIM software, asset intensive

organisations in water and other sectors

can model the complete lifecycle of assets,

anticipating changes and how they will

impact on services. This results in better

business decision-making that helps make

assets more resilient and reduces service

disruption and the risk of regulatory fines.

AIM4 also delivers improvements in

software functionality, such as the ability

to analyse risk per region and per asset

base. This allows users to examine factors

such as planning constraints, along with

the associated risks of not commencing

work at specific points in the future, at a

granular level.

In addition, AIM4 introduces the option of

web services, meaning AIM is no longer a

standalone piece of software with limited

client interaction. Third party systems

can now connect directly to AIM to enter,

extract, and link up data, creating an allround



The regulatory asset management

period 2020-2025, AMP7, requires water

companies in England and Wales to

calculate investment needs and provide

evidence on expenditure over a five-year

period. By allowing asset managers to

explicitly model what happens to assets

under various conditions, certain questions

can be asked such as how assets will

deteriorate with how much risk and the

associated costs due to failures in the


Reflecting on the growth of the AIM

software, Jonkergouw said: “Initially, AIM

was used for underground linear assets

such as sewer and water pipes, water

mains and trunk mains. Then, clients

wanted to do more types of modelling to

Probit’s asset investment manager (AIM) software is

helping water companies in England and Wales save

time and cost in planning works

include above-ground assets, such as

wastewater treatment plants and pump


“Now it can be used to synchronise works

across the whole water and wastewater

asset base, and potentially with other

sectors too. This is a perfect example of

the adaptability and flexibility of the AIM

software to meet new client requirements

and we hope to continue these strong

working relationships with AIM4 and



AIM software also delivers digital

solutions and asset management across

other infrastructure intensive sectors

including power and transportation. The

next step is to bring other utilities into

the cross-sector optimisation work. For

example, synchronising gas works to

be done at the same location and at the

same time as planned roadworks.

“There has been ambition for this in the

past,” said Jonkergouw, “but until now

the tools, technology and processing

power were not available nor did the

sectors have the datasets needed. Now

that asset management streams have

the potential to come together in a single

optimisation investment framework in

AIM, this could start to drive cross-sector

collaboration and trials.”

ABB published the first in a series

of new reports for the energy and

wastewater sectors to highlight the

impact that technology can have

in enabling industrial customers to

reduce carbon emissions and manage

the energy transition for a more

sustainable future.

With the United Nations predicting a

40% water deficit by 2040, ABB has

conducted research to reveal how

better use of wastewater could relieve

pressure on water supplies.

When treated effectively, wastewater

can be returned to the water cycle for

reuse, proving a valuable but often

untapped resource in tackling water

scarcity. Importantly, it also lowers the

levels of untreated sewage pumped

into rivers and oceans, which have

hugely negative impacts on public

health, the environment and marine life.

“Global data shows that only half of

our wastewater is properly treated,”

said Brandon Spencer, president,

ABB Energy Industries. “Allowing

untreated wastewater back into

our water courses not only has a

disastrous effect on fisheries, animals,

marine biodiversity, and public health,

but it is also a terrible ‘waste’ of this

commodity. We need to be doing


Treating wastewater, however, requires

a lot of power, with the industry at large

consuming up to 3% of the world’s

total energy output and contributing

over 1.5% to global greenhouse gas


Seeking to redress this balance, ABB

has conducted nine months of research

and modelling with an independent

economist, to demonstrate how greater

adoption and integration of process

automation technologies, can deliver

both carbon and cost savings to enable

more efficient treatment of wastewater.

The findings reveal that in wastewater

sites, utilities could reduce carbon

emissions by up to 2,000 tonnes per

annum, the equivalent volume of CO2

responsible for 30,000 tonnes of glacier

mass lost every year. With over 50,000

existing wastewater plants worldwide,

the opportunity, if scaled, is upwards of

100 million tonnes of CO2 saved.

Furthermore, in applying a robust

package of process control and digital

solutions, water companies could reap

annual operational savings of up to

US$1.2m (9.5%) per plant, opening

revenue streams to ensure higher

volumes of wastewater are treated and

less is discarded in our rivers and seas.

“ABB is committed to leading with

technology to preserve precious

resources such as water and energy,

and ultimately enable a low-carbon

society and a more sustainable world.

In 2021, we have reduced our own CO2

emissions by 39%, compared with the

baseline year of 2019, and as part of

our Sustainability Strategy 2030, we

are working with our customers with

the aim of reducing their annual CO2

emissions by at least 100 megatons by

2030,” said Spencer.

The global wastewater market, driven

by the need for more freshwater,

population increase, and stringent

environmental regulations, is projected

to grow from $300bn in 2022 to $490bn

by 2029.

The reports’ economic modelling

was undertaken by independent

economist Steve Lucas of Development

Economics in conjunction with ABB

Energy Industries and supported with

desktop research of academic and

industry sources. ABB will publish

further economic reports focused on

the offshore, power and chemicals

markets across 2022 and 2023.

The National Dairy Development Board in India worked together with Lars to provide better

management of dairy wastewater

CleanEdge Water offers technologies for

treating industrial wastewater, focusing

on resource recovery and sustainability.

Headquartered in Singapore, and founded

and managed by a group of professionals

dedicated to the environment, development

and sustainability, the company aims to solve

complex problems and design integrated

solutions to increase recovery, sustainability

and profitability, with a focus on technical

upgrades with disruptive technologies.

CleanEdge Water’s group company, Lars

Enviro, is an environmental engineering

organisation in India with more than 25

years in the field of water, raw water and

wastewater, with emphasis on industrial

wastewater, recycling systems, sewage

treatment and waste to energy.


Biogas/Bio-methanation through effluent

treatment plants

Via generating energy from the feed-stock

such as press mud and cow manure, the

biogas generation of anaerobic digestion

can manage energy supply and waste

management issues. This solution avoids

contaminating groundwater and the emission

of greenhouse gases, while also recovering

energy in the form of steam, biogas, power,

CBG, and more. The generated digestate can

sustainably substitute synthetic or chemical

fertilisers and strengthen the farm ecosystem.

Wastewater recycling plants

Lars aims towards simplifying industrial

wastewater recycling. The company’s

WWRP solution use available resources and

Condensate polishing units

Distillery condensate is generated as a byproduct

of multi-effect evaporation of spent

wash, while grain wash generated as wastewater

stream from alcohol production process. The

effluent contains organic load and can have

a detrimental effect on the environment. Lars

has developed technologies considering PCB

stringent norms and implementation of ZLD.

Together with the recycling plant, the CPU treats

condensate and makes it reusable by offering a

combination of anaerobic, aerobic technologies

along with tertiary (sand filters, UF, RO) and

disinfection (UV) treatment. This recycled water

reduces fresh water demand.

WTE plants

Solid waste management through anaerobic

digestion can provide customers with renewable

energy and address waste management

issues. Energy can be recovered in the form of

steam, biogas, power, bio CNG, and more. The

digestate can substitute synthetic fertilisers and

strengthen the farm ecosystem.

The decentralised WTE Plants can minimise

solid waste at the source. Lars’ technology-



based solutions can strengthen solid waste

management. manage health risks and

environmental pollution through plug-and-play


Biogas to renewable energy

Lars Enviro’s anaerobic digestion can handle

different organic substrates from food waste

to sewage sludge, to produce renewable

energy. This can be used as an alternative,

renewable automotive fuel through gas

grid/cascades and also to replace LPG for

industrial needs.

From pre-treatment techniques required

ahead of anaerobic fermentation, right up

to the required post-treatment of digestate,

composting and biogas upgrading, Lars

possesses one of the highest design and

operating experience of biogas plants,

producing about 1000MT CBG per day,

or 226MWH equivalent of potential power



CleanEdge also offers a range of water

treatment systems, ranging from raw water

treatment plants, UF and RO plants, DM

plants, and desalination solutions.


LESMAT is an anaerobic solution for

seasonal industries generating high strength

wastewater. It is an optimal solution

when footprint is a constraint. Here, a bio

film of desired bacteria is attached to a

structural media to facilitate reduction and

better treatment. CleanEdge has so far

commissioned 56 LEMSAT units.


LESBAR is a biodigester for the treatment of

low- and medium- strength wastewater across

breweries, and sugar and food processing,

etc. Equipped with an in-house design offering

a three-tier GLSS (gas liquid solid separator)

system, LESBAR comes in different materials

like stainless steel, mild steel with epoxy/FRP,

complete FRP, and more. Thus far, 164 units

of LESBAR have been commissioned.

CleanEdge offers

raw water treatment

plants, UF and RO

plants, DM plants, and

desalination solutions


A better engineered version of the

conventional continuously stirred tank

reactor, LESAR is an optimal solution for

biogas recovery or treatment of highstrength

industrial wastewater. With over

100 installations across industries and

continents, LESAR can be applied a wide

range of industries, from distilleries to

manure and sludge digestion. Till date, 106

units of LESAR have been commissioned.


Lars Enviro was contacted to design,

supply, and commission a fermented wash

(raw spent wash) biogas plant for the Kooll

Company, in Talisay City, The Philippines.

The company is one of the largest

producers of alcohol- and beverage-grade

liquid carbon dioxide, supplying to major oil

and beverage companies in the country with

a flow of 980m 3 /day at a COD of 120,000mg

per litre. The plant Lars constructed thus

generated about 34,500m 3 of biogas per

day, which was utilised as fuel in boiler.

With the plant, Lars enabled the reduction

of highly pollutant wastewater and the

ability to handle shock loads. With one

seeding and commissioning required,

there was no need for specialised culture

and nutrients for further operations, and

no need for chemicals once the plant had


The plant was also capable of handling

a higher volume of wastewater and can

restart rapidly after a shutdown. The

biogas produced can be utilised in boilers,

canteens, furnaces, CBG, for electricity

generation. The treated wastewater, which

contains high nutrient, can be used as

organic compost to improve soil fertility,

reducing water demand and the economic

burden (inorganic fertilisers) of farmers.



The National Dairy Development Board was

set up by the Parliament of India. With its

main office located in Anand, Gujarat, with

regional offices throughout the country, the

board was created to finance, support and

support producer-owned and controlled

organisations. Its programmes and activities

seek to strengthen farmer cooperatives and

support national policies that are favourable to

the growth of such institutions.

The dairy industry is the most polluting food

industry in terms of water use during the

production of milk and milk products. The

wastewater contains dissolved sugars, proteins

and fats, which is organic and biodegradable.

Dairy wastewater is thus considered as

possessing high concentrations of organic

matter and BOD. It is estimated that dairy

industries generate 2.5-3 litres of wastewater

per litre of milk processed.

If left untreated, dairy wastewater will pollute

land and river systems. Hence, proper

treatment of dairy wastewater is necessary

before disposal in the environment, as per the

Maharashtra pollution control board (MPCB)


With experience in managing dairy waste from

companies such as Etika Dairy from Malaysia,

and Hatsun Agro Products from India, LARS

had supplied preliminary, anaerobic, aerobic

treatment, alongside tertiary treatment like

MGF and ACF. Lars provided a single point

solution to treat liquid waste water generated

from the plant, and treated water was used for

irrigation purposes.




on 2027 goals

As the water industry is poised for significant

changes in climate, smart solutions, and more,

Agatha Wong speaks with Sabrina Soussan, chairman

and CEO of SUEZ, to find out more about the

company’s strategy in the years to come.

To begin with, can you share with us your

experience as CEO of SUEZ since your

appointment earlier this year?

Soussan: The first months have been filled

with much listening, interacting and getting

to know as many colleagues, from across 40

countries we operate in, as possible. I have

been particularly impressed by our Chinese

Team which has been working under very

difficult conditions due to lockdowns

imposed as countermeasures to COVID-19.

Over that period, we have also achieved a

number of significant milestones. We have

completed three acquisitions: hazardous

waste in France; EnviroServ, the leader in

waste treatment in Southern Africa; and

our former recycling and recovery (R&R)

assets in the UK. These moves highlight

the optimism and confidence of our

shareholders in SUEZ’s future. Once the

acquisitions are finalised, the SUEZ global

team would have grown from 35,000 to

44,000 employees and our annual revenue

risen from €7.5 to €9bn.

Can you comment on SUEZ’s new

strategy? What are some of the changes

that customers can expect from it moving


Soussan: Our plan is an ambitious one,

in line with the increasingly important

environmental challenges facing our world.

My ambition for SUEZ is that we become the

trusted partner of industrial companies and

local authorities for circular solutions in water

and waste. This strategy will progress SUEZ

towards its goals through three pillars: focus,

differentiation and enhanced value creation.

• We will focus on our core business: the

complete waste and water value chains,

including related services, and concentrate

our efforts on certain particularly buoyant

markets, such as Asia, the United

Kingdom, Italy, India, Australia, the Middle

East and Africa.

• We will differentiate by offering a unique

value proposition to our customers, built on

our proven infrastructure, on our expertise

with a recognised leadership in smart and

digital solutions, on end user experience,

and on innovation.

• We will offer enhanced value creation by

being more selective with our projects,

making digitalisation and service

excellence our drivers for competitiveness.

By 2027, this strategy will enable us to be

a benchmark in our industry, recognised

for our agility, capacity to create value, and


SUEZ will invest an additional €860m

compared to the previous period to

address new environmental and energy

challenges. What do you think are the most

pressing issues in the industry, and how

will SUEZ continue to create differentiated

solutions to meet these needs?

Soussan: Our industry currently faces

historic challenges, characterised by

strong momentum for green transition from

governments, industries and customers.

SUEZ has been part of this evolution by taking

the lead in action and expanding its expertise.

We will continue to devote our efforts in

addressing environmental challenges

regionally in this fast-changing world. True

to our partnership culture, we will double

our investments, alongside our customers,

mobilising an additional €860m compared to

the previous period for the digitalisation of

water networks, decarbonisation and energy

efficiency, for example. We will also increase

our innovation capacity, with a 50% increase

in our R&D budget by 2027 to develop

differentiated solutions for preserving water

resources, combating pollutants, recycling,

producing green energy from waste; and

reducing our own carbon footprint, as well

as that of our customers. Digital technology

is also an important lever for improving

performance and agility and for developing

new solutions. We will continue to invest

in this area, with the goal of doubling our

revenues from these activities in five years.



How will SUEZ work towards its strategic

objectives and maintain its position for the


Soussan: As we grow strategically and

reposition ourselves to be a leading, fullservice

provider across the entire water

and waste value chains, we will have to be

selective with where we invest our resources

and which projects we undertake. Pursuing

strategic opportunities requires efficient

decisions and strong capital support. We

are fortunate to have a strong backing from

our consortium of shareholders, with ample

capital and strategic alignment.

Second, we will also need to maintain our

leadership in sustainable development.

By the end of 2022, SUEZ will unveil its

sustainable development roadmap, outlining

our contribution, ambitions, and quantified

targets for climate, nature conservation, and

social matters.

Third, we need to engage all stakeholders.

We have made a commitment for employees

to hold 10% of the capital within the next

five to seven years through an employee

shareholding plan. We are promoting diversity

and equal opportunity, and we are renewing

our social commitments through inclusion

initiatives, notably through our social inclusion

subsidiaries, such as Rebond in France.

SUEZ will also be focusing on both mature

and emerging markets. On that vein,

what are your goals for South East Asia in

particular? What unique opportunities for

growth and investment do you see in this


Soussan: South East Asia is an important

region for SUEZ because of our historic

presence in this region and the rising demand

for environmental improvements and the

need to supply top class water and waste

services to the growing populations. As part

of our desire to focus our activities, we will

keep concentrating our efforts, notably in the

Philippines, Indonesia, Vietnam and Thailand,

as well as others. We have numerous projects

in these nations, managed by strong local

teams. Additionally, we provide them with

technical and financial support from our

worldwide SUEZ organisation. Our goal

is to expand further by working with our

partners and clients. By 2027, SUEZ aims at

generating approximately 40% of its revenue

in international markets.

Can you share with us more on the

new, simplified, and customer-focused

organisation that will be structured

around water and waste? How will this

organisation further benefit SUEZ’s

customers and deliver a more robust

commercial and operational experience?

Soussan: We plan to become a more

agile and customer-focused organisation

structured around our two core businesses,

water and waste. Globally, we will organise

our businesses as one “Water” and one

“Waste” division. Our new structure and

operating model will enable us to better

put the customer at the forefront of our


What are your hopes and visions for

SUEZ as it works towards its strategic

plans? What are you most excited about

for SUEZ’s journey in the next five years?

Soussan: I’m looking forward to seeing

this ambitious, yet realistic, strategic plan,

which is rooted in a purpose of making key

contributions to society, progressing step

by step. I’m convinced that SUEZ, through

its water and waste activities, has been

playing and will play a vital role everywhere

it operates in improving people’s quality of

life on a day-to-day basis.




for sustainable action

Cooperation with government bodies, private

companies, and academic institutions will be vital

in ensuring the longevity of green strategies.

By Agatha Wong

The announcement of the Environmental

Sustainability & Energy Efficient Centre (ESEE)

by Singapore Polytechnic (SP) at the “Values-

Based Green Transition – For Singapore

Businesses” event brought together key

players ranging from government agencies,

private companies, trade associations and

chambers, demonstrating a united resolve in

supporting the green transition of companies

across various sectors.

Serving as a one-stop provider of services and

counsel for sustainable practices, companies

can expect the knowledge and expertise

of participating members as they tackle

common teething issues such as operational

costs and administrative process. Similarly,

companies like Grundfos will be tapping

into their portfolios to support firms across

various industries. The end result: a symbiotic

arrangement where all parties benefit mutually

from the expansion of greener strategies.

“The MOU with SP will allow us tap into higher

learning institutions, where Grundfos comes in

with vast knowledge and applications; as well

as experience in bringing about sustainability

solutions. SP will also provide us a platform

to also enter more ecosystems and connect

with more industries, policy makers and

higher-learning institutions, and get things off

the ground,” said Eric Lai, regional managing

director of Industry – APAC, and country

director for Singapore, at Grundfos.

On that front, Grundfos will be able to offer its

portfolio of services and products, designed

for water and energy efficiency, to a wider

audience. Humphrey Lau, former

group senior vice-president of global

industry business at Grundfos, shared

at the conference the six projects

which the company has planned,

drawing from the reduction of Grundfos’

carbon footprint by energy consumption

and the electricity bill as per prior

feasibility studies on solar panels and PV

installations. Bearing its past experience

and expertise, the ESEE will thus provide

Grundfos the context needed to support local


“In order to bring collaborations like this to

life, it is important to have a relevant context,

and that is why it is so important for us to

have collaboration with local institutions

like SP, else we’d be coming up with global

concepts that are too far away,” added Lau.

RACE TO 2030

The need for sustainable action has never

been clearer. As the 2030 deadline set out by

the United Nations Agenda for Sustainable

Development swiftly approaches, with the

organisation stating that the world is nowhere

near said goals, there is a strong call for more

to be done, and quickly. In that regard, it will

be vital for key players to help as many firms,

both large and small, as possible. On a local

level, this also means reaching out to small

and mid-sized enterprises (SMEs), which

form a critical part of Singapore business


“Local companies have a big role to play,

because they are part of the larger industry

From left to right: Eric Lai, regional managing director

of Industry – APAC, and country director for Singapore

at Grundfos, and Humphrey Lau, former group senior

vice-president of global industry business at Grundfos

that consumes most of the electricity in

Singapore. For us, coming in as a global

company, it is important to engage at the

right-levels regarding using less to produce

more — both from the water and energy

aspect. Another aspect would be bringing

along digitalising technologies, having sensors



in place; getting more shove in terms of the

consumption and demand requirements. To

regulate the energy and water consumption

on a needs-based system rather than the

previous time-based and experience-based

systems can allow us to get heart of the

issue, which is increasing sustainability and

using less for more,” said Lai.

While Singapore delivers a conducive

environment for the implementation of

sustainable initiatives, it is also necessary

for global companies such as Grundfos

to reach out to other countries around the

world. Crucially, there is also a protracted

call for enabling sustainable change in the

region. South East Asia, in particular, can

benefit from a fortification of their water

infrastructures alongside greener strategies,

killing two birds with one stone. In that

regard, the region presents a reservoir

of untapped potential and business

opportunities for water companies to lead

the change.

“For the region, we see a lot of potential to

cover the market, especially in South East

Asia. There are many cities and industry here

that can escalate their water reductions,

water efficiency and quality levels. Through

this network, we can also drive the trend in

terms of sustainability for the goodwill of

climate change. It can also bring about a

sustainable business model. This can really

fund and produce good not just for the

company, but for the environment in the long

run,” shared Lai.

Lau shared a similar sentiment: “Asia

represents an industrial hub, not just in

Singapore but across South East Asia, and

even Japan and Australia, China and India.

This will only in the coming years continue

to intensify in terms of water, energy, and

resource consumption. You can think of it

as a huge pilot plan where there is a need

for solutions. We see a huge opportunity

for Grundfos to co-develop solutions with

industry players in this part of the world.”


As a global company, Grundfos has had a

front-row seat in witnessing the changes

necessary for the sustainable transformation

of the world’s industrial ecosystems. More

than that, as providers of solutions in water

and energy management, the company

has a keen awareness in the importance

of collaboration for fruitful changes to take


The ESEE serves as an instance where multifaceted

cooperation across different sectors,

be it private or public, can work together

towards a common goal. This is testament to

the enormity of the climate challenge at hand,

where it is not sufficient for a single player

to contribute to the fight. For pronounced

change to take effect, it will be vital for

agencies and companies to come together in

a common goal.

With input across public

and private sectors, and

academic institutions,

the conference and

ESEE served as proof

of the need for greater

collaboration in enacting

sustainable change

Lau remarked: “There are issues and

challenges in this world which are so big that

not one company nor sector can handle by

themselves. The COVID pandemic had been

a great example showcasing how private

pharmaceutical companies can work hand-inhand

with governments to develop vaccines in

an unprecedented short amount of time.

“Climate change, I think, is another major

issue that not just one sector can work alone

on. I believe that Grundfos holds a small

number of keys and tools that can add onto

this larger equation, and we’d very much like

to invite everyone on the value chain to work

together with us.”

Quoting Dr Amy Khor, Senior Minister of

State for Sustainability and the Environment,

and Transport, who graced the event as the

guest-of-honour, and stressed the need to be

bold in the sustainability journey, Lai added

that the issue of sustainable transformation

no longer lies in the “why”, but rather the

“how”. Concrete measures demonstrating the

commitment and collaboration between all

parties will be vital to setting the path for the

sustainability agenda moving forward.

“The event demonstrates that there is a lot

of commitment from commercial and higher

learning institutions, as well as government

bodies who want to support this. Therefore, it

really is time for us to take action into our own

hands and take a step forward.”

Dr Amy Khor, Senior

Minister of State for

Sustainability and

the Environment, and

Transport, graced

the event as the






What corporate sustainability

could look like in South East Asia

As the need to fight climate change increases, companies have to re-consider

their corporate priorities to ensure sustainability across all areas of production

and their industries as a whole. By Kimberly Liew

(COP26) held in Glasgow last year revealed

that organisations should reduce emissions

to keep temperature rises within 1.5°C, to

prevent climate catastrophe. Companies thus

need to be strategic in their plans for water

sustainability. They need to innovate solutions

to these pre-existing issues, while also

ensuring their own practices are sustainable


This includes where they source their water

supplies. Agnihotri stated that LANXESS

regularly assesses current and future water

stress to ensure the human and ecological

demand for water is sustainable. Over 90%

of their water withdrawal are in areas with

low water stress. They have also identified

four water risk sites and have initiated

measures to reduce water withdrawal.

For companies working in South East Asia,

water sustainability is an issue that needs

to be seriously considered. Despite being

home to 60% of the world’s population, the

region only has access to 36% of the world’s

water resources, making the per capita water

availability the lowest in the world.

These challenges are only furthered by

climate change causing extreme weather

fluctuations and rapid urbanisation. The

United Nations Climate Change Conference


LANXESS, a specialty chemicals developer

with solutions in water purification, is one of

the many companies which has re-oriented

itself towards sustainability. In their efforts

to be more environmentally minded, the

company has to consider their every action

and its impact on the larger ecosystem.

“Our motto is ‘Good for business, good for

community’. This is based on the conviction

that with our products and our expertise in

the field of sustainable development, we can

make important contributions: supporting our

customers, protecting the environment and

improving the quality of life for all people. In

this way, we create sustainable value for all

stakeholders. And we remain a sustainable

company,” said Vinod Agnihotri, vicepresident

and head of materials protection

products business unit, Asia-Pacific,


The company has also launched a global

water programme in 2020, designed to

promote sustainable water management

and continuously improve the ways

they use water. The programme has

three primary goals: ensure global

water management, foster local water

stewardship and to ensure the company

is connected to communities “beyond

the gates”. The company hopes to

achieve each goal through enacting

these methods, respectively: transparent

reporting on water management and use,

addressing issues in local water systems,

and safeguarding the drinking water

supply of the communities they operate

in. Ultimately, LANXESS’ global target is

to reduce annual water consumption by

2% despite organic growth, while reducing

water withdrawal from locally identified

water risk sites at an absolute of 15% until




Water is not the only form of sustainability

LANXESS is committed to. Since 2021, the

company’s sustainability committee has

been deemed the “top decision-making

body”. Since the company’s re-structuring,

it has learnt that clear and specific goals

are the best way to enact sustainability. To

that end, it has implemented three pillars

to ensure climate neutrality: purchasing

sustainable raw materials, ensuring green

logistics, and expanding its range of climate

neutral products with the “Scopeblue” brand


The company has also reportedly halved

their direct emissions, from 6.5 million

tonnes of carbon dioxide equivalents (CO2e)

to 3.2 million tonnes. This was achieved

through minimising emissions from their

production and external energy resources.

LANXESS is now hoping to eliminate their

indirect emissions in the upstream and

downstream value chain by 2050. The

company has also contributed to causes like

the OneMillionTrees movement in Singapore,

planting 50 trees across the Kranji-

Woodlands Nature Way to revive the streets

with lush greenery and reduce greenhouse

gases through carbon sequestration.




Water companies play an important role

in resolving the water crisis in South East

Asia. “With population, pollution, and water

shortages growing unabatedly, collaboration

between the public sector and water

companies must be established to turn

water-scarce cities into high-tech hydro

hubs,” Agnihotri stated.

This schema has already been implemented

in Singapore for decades, through the Public

Utilities Board (PUB)’s role in implementing

and expanding the NEWater water filtration

system, which was used to reclaim

wastewater into clean and usable water

for Singaporeans. The project’s success is

evident from 40% of Singapore’s water supply

stemming from recycled sewage, which is

expected to rise to 55% by 2060. Agnihotri

thus encouraged water companies to work

closely with the public sector and provide

insight into technologies that can expedite the


But this is only one part of the solution.

Agnihotri believes that water companies

should also work with other industries like

the chemical industry to create innovative

solutions for water treatments. He cited the

example of LANXESS’ Lewatit ion exchange

resins, which were used to treat and process

wastewater across various industries.

As he explained: “We have produced ion

exchange resins that can remove undesirable

substances from groundwater to turn it into

drinking water. The principle of ion exchange

has also found a wide variety of applications

in the household. When used in water filter

pitchers, Lewatit products remove water

hardness because many people much prefer

the taste of tea and coffee made with soft

drinking water.”

Water sustainability cannot be achieved

through the efforts of water companies alone,

however. Water stewardship on the part of

companies outside the water industry is also

just as important. Agnihotri emphasised that

companies should understand their collective

responsibility “in water usage, catchment

context and shared risk in terms of water

governance”. It is only by understanding

and collaborating with others that share the

same knowledge that meaningful change

can take place.



Currently, the two most critical issues facing

the region are securing an adequate water

supply and ensuring water contamination

is addressed at its source. Most water

technologies are currently focused on

recycling wastewater and water recovery.

While these measures are effective, it

is likely not enough to guarantee water

security and sustainability.

One key issue in water security is preventing

and responding to future health crises,

in light of the COVID-19 pandemic and

its effects on water management. Water

services should thus begin considering

sustainability and long-term resilience as

part of their infrastructure.

For instance, Agnihotri suggested the

industry can empower water service

providers with digital innovations that

are increasingly available to manage

uncertainty and enhance the experiences

of service providers and their customers.

Green recovery strategies should also be

implemented, which includes investments

in water and sanitation that will deliver

accelerated economic growth, while also

being sustainable for people and the


Water plays a significant role ecologically

and socially beyond its role as an economic

resource. Access to water and sanitary

facilities is a fundamental human right. Its

availability and quality are global challenges

that must be addressed at a local and

regional level. Similarly, we believe that the

sparing use of water is crucial. Scarce water

resources need to be handled consciously

and carefully and viewed as an investment

in the future,” concluded Agnihotri.





Jakarta’s water


Jakarta’s water network

before the installation of

Cla-Val pipes

In 2005, Jakarta, the capital city of

Indonesia, was losing nearly 50% of

its produced water from leakages

in their water network. At the time,

management of the network had

been privatised into two separate

concessions, with one section

being managed by Palyja. Palyja,

a SUEZ company, is the water

distribution company responsible for

disseminating water in the western and

southern areas of central Jakarta.

The section of the network managed

by Palyja extended for over 3,000km

and consisted of mainly non-metallic

piping in sizes 25mm through



1,200mm, with unit pressure of at most 15m.

At the end of many zones, the pressure

could typically be recorded as zero for most

of the day, as the traffic appeared to be

permanently grid-locked like most cities. The

systems ranged from newly built to old and

abandoned. Non-revenue water (NRW) was

recorded to be typically 75%.

An example of the Cla-Val pressure system

used in Jakarta

The 90-series control valve by Cla-Val

One key to permanent leakage control is

to not only reduce the leakage, but to also

maintain a low leakage level. The approach

developed for the water networks in Jakarta

was successful in identifying leaks, but not

controlling them. It became apparent that as

soon as a leak had been located and repaired,

another broke elsewhere.

According to Cla-Val, the benefits of lowering

pressure has been utilised across the world,

but these applications were typically with

higher pressures. What was less known

was the effectiveness of pressure control at

mitigating leakage rates with low pressures,

which was the main issue in Jakarta.

High leakage creates high flow, which in turn

increases head loss and reduces pressure.

When the leaks were repaired, the reverse

occurred. The resulting higher pressures

increased water loss through small leaks, as

well as the increase in new leaks. It became

clear that the solution to the problem was

pressure control. However, it was unknown if

a pressure control system could be effective

with pressures as low as 10m.

Veolia supports Mölnlycke’s

sustainable network

Tucked in the industrial heart of Kedah, Mölnlycke’s newest glove factory

will not only support regional demand for medical supplies,

but also the company’s sustainable goals.

At a glance, the plant is equipped with the following technologies:

• Process Water Treatment Plant

° Multimedia filtration

° UV sterilisation

° Hydrex chemical dosing

Wastewater Treatment Plant

° Primary treatment/clarification – Multiflo Pack

° Biological treatment – AnoxKaldnes Moving Bed Biofilm Reactor (MBBR)

° Secondary treatment/solid separation –Idraflot Dissolved Air Flotation

° Sludge treatment – Sludge thickening and dewatering

• Hubgrade Digital Monitoring System

shared Olivier Estienne, country director for

Malaysia at Veolia Water Technologies.

Inaugurated in Sep 2022, the new Mölnlycke

plant in Kulim, Malaysia, will enable the

medical product manufacturer to expand

their glove manufacturing capacity by 60%,

allowing the company to meet current and

future demand for surgical gloves. Mölnlycke

also hopes to meet its goal for reducing water

consumption by up to 50%, using Veolia’s

digitalised systems 1 .

In partnership with Veolia Water Technologies

and Engie, Mölnlycke has also implemented

sustainable energy and water/wastewater

treatment facilities at the new plant, despite

the manufacturing process for surgical

gloves being a resource-intensive one. Jean-

Christophe Guillou, vice-president of global

Mölnlycke’s latest plant

in Kulim, Malaysia, spans

across 29,164m 2

operations for gloves at Mölnlycke, had

approached Veolia for the project.

Veolia’s solutions for the plant will enable

the company to achieve a circular economy

and reduce waste in their manufacturing

processes, as well as recycle and reuse

process water both on-site and/or via third


“What is difficult when it comes to wastewater

treatment for industrial use is understanding

what is being manufactured and what kind

of wastewater is generated. Our process

included visiting the existing team and the

facility, to see what was the best sustainable

design that Veolia could bring for the plant,”

“Sustainability at Veolia entails enabling our

customers to conserve resources. This can

be water, power, or chemical resources.

Glove manufacturing requires a lot of

chemicals, similar to wastewater treatment.

At each step of glove production, water is

needed, and wastewater is generated. The

idea was to find the best possible way to

segregate wastewater such that we didn’t

have to apply the full process to each

part of the stream. In this way, energy and

chemical consumption is reduced to what

is needed for treatment. If we start diluting

polluted water, for example, we’d need to

treat a higher volume of water. However,

if we treat only a small, concentrated

amount of water, we will only need to bring

in the chemicals needed for that volume,”

explained Estienne.

Another aspect of Veolia’s sustainable

model was embedded in Mölnlycke’s



schema for the Kulim plant itself. As the site

will be built in stages, Veolia will match their

services to its corresponding phases. The

first stage saw Veolia helping Mölnlycke

comply with discharge standards, while

the second will aim at improving water

reuse and striving towards the goal of

zero water discharge. Altogether, these

implementations will support Mölnlycke

in their efforts towards reducing carbon



Water and wastewater treatment begins

in the Process Water Treatment Plant,

which includes multimedia filtration and

UV sterilisation. Within this process, raw

water from Syarikat Air Darul Aman (SADA)

is treated chemically before it flows into

the multimedia filter (MMF), at a flow rate

of 100m 3 /h with more than 2mg per litre of

chlorine. To comply with stringent bacterial

count requirements, UV disinfection is

deployed as the last treatment step prior to

consumption at the glove production line.

The objective of this stage is the reduction

of total suspended solids and bacteria


Meanwhile, the wastewater treatment

plant has been distinguished into three

different stages and objectives. In the

primary treatment and clarification stage,

wastewater from the surgical glove

production line flows into the Multiflo

unit. Sedimentation begins here where

suspended solids and specific minerals

are blended with coagulants to form large,

easily settled flocs. These flocs accumulate

at the bottom of the equipment while

clarified water flows to the next phase for

further treatment. Here, total suspended

solids and zinc are reduced, and the

accumulated sludge in the bottom of

the tank is regularly removed either via a

suction draw-off or scraper mechanism.

After sedimentation, the clarified

wastewater flows into the biological

MBBR tank for biodegradation. In this



biological treatment stage, Veolia’s biofilm

carriers move freely by aeration, while

microorganisms feed on contaminants

and further purifies the water as part of its

biological activity. Ammonia, nitrogen, and

BOD/COD are removed as a result.

The wastewater stream is then preconditioned

with coagulant and flocculant.

This is where suspended solids are brought

to the surface of water via microbubbles as

part of the enhanced separation, through the

Idraflot dissolved air flotation. Floated sludge

is then scraped off from the water surface.

Thereafter, sludge from the Idraflot and

Multiflo is then chemically conditioned for

further thickening before being pumped into

the filter press for dewatering. The aim is to

achieve 20% dryness of dewatered sludge.


Mölnlycke’s wastewater treatment

processes forms part of a greater plan for

resource conservation in Malaysia. The

recent 12th Malaysia Plan highlighted the

government’s plans for comprehensive

water transformation, with integrated

wastewater treatment plants to be

constructed for the management and control

of effluent discharge in industrial areas, and

encouraging a circular economy in the water


“What the government wants is closely

aligned to what multinationals have set

as their KPIs; it is also similar to what the

people want. Reducing consumption and

addressing water scarcity constraints

are the most pressing factors — though

Malaysia receives a lot of rain, water is

distributed unequally across the country.

Klang and Kuantan, for example, face water

scarcity issues annually. Similarly, with more

the MBBR tank, where biofilm carriers remove

BOD, ammonia, and nitrogen

2 The Idraflot removes suspended solids, oils and

greases, and insoluble COD

industrial facilities being built in Kluang and

Penang, water resources are expected grow


“The target, then, is to ensure that we do not

overuse water reserves. Veolia provides its

clients with access to the water they need by

preserving and replenishing them. With that,

we’re pushing wastewater reuse, which can

be applied across a variety of applications,

be it landscaping, flushing, or drinking.”

With the government leading the way forth,

and multinationals such as Mölnlycke

setting the tone for a greener future, the

Kulim plant was a success for all involved

across the board. Estienne also attributed

this to the planning team’s adherence to its

sustainability targets and its criterion-based

decision making hastened the construction

process. As the plant begins the first phase

of its operations, Veolia is keen on working

with the company further to get a stronger

grasp on what will be needed in the years

moving forward.

“Our on-site team will continue to work

with Mölnlycke to monitor and study their

wastewater streams over the coming years

— especially if there are changes to the

composition of the wastewater produced.

This way, we can provide solutions to

address Mölnlycke’s needs and achieve their

long-term sustainability targets.”

IIoT and Industry 4.0

Elektra is an IoT-enabled

digital controller produced

by Seko which allows

operators to programme their

equipment, as well as access

live and historic dosing pump

data on demand from any

location via smartphone

Outside of the consumer sector, a branch

of IoT has emerged within industries,

including manufacturing, healthcare and

water treatment. Known as Industry 4.0 or

the Industrial Internet of Things (IIoT), the

integration of technology in physical devices

can help managers make improvements to

operational efficiency, energy consumption

and environmental impact.

This technology is changing what is possible

in traditional motor-driven, solenoid and

peristaltic pump applications, including liquid

transfer and chemical dosing in processes

as varied as swimming pool, wastewater and

cooling water treatment.

From flocculation and coagulation to pH

correction and other water-treatment

applications, operators seeking to improve

efficiency and sustainability are increasingly

specifying for web-enabled pump systems.

For example, the capacity for “live” document

sharing creates the potential for equipment

manufacturers to update digital installation

guides and operating manuals to reflect

changes in design or software, before

immediately uploading the latest revisions to

the cloud.

As the fourth industrial revolution approaches

its second decade, we are witnessing a swift

development that began within the consumer

market and is now progressing into the

manufacturing and industrial automation


This technological growth, commonly

referred to as the Internet of Things (IoT), is

a meeting between smart device technology

and data generation, processing and

accessibility. Within the consumer sector,

this has resulted in the creation of the smart

home, where users benefit from the ability

to remotely control a multitude of household

appliances — from lighting and heating to

kitchen appliances, security devices and

entertainment systems — via computers,

smartphones and tablets.

And there is no sign of this boom slowing

any time soon, as Statistica estimates that

the worldwide installed base of internetconnected

devices will increase from 10

billion today to more than 25 billion by the end

of the decade 1 .

This allows potentially unlimited changes to

be made, saving on printing costs. Engineers

and operators can thus have access to upto-date

literature. In addition to accelerating

installation, set-up and commissioning,

managers can reduce associated time and

costs, while helping to ensure a smoother

user experience.

During equipment operation, IoT systems

receive information from pump sensors which

are constantly harvesting data on multiple

values — including cycle status, chemical



consumption and vibration monitoring. With

both historical and real-time data at their

fingertips 24/7, users can make informed

decisions relating to system performance and

perform adjustments to formulas, flow rate,

unit of measure and other parameters, as well

as altering pump operating modes such as

manual, batch and timed.

In addition to making efficiency

improvements, operators are able to budget

with greater accuracy and confidence while

streamlining stored chemical volume, which

is useful on small sites where space is at a


Moreover, web-connected pump systems

have the capacity to convert chemical

consumption volume into the equivalent

financial value, which allows projected

savings to be precisely calculated when

considering dosing adjustments. These

figures may also be presented to senior

management to justify programme changes

or to demonstrate performance improvement

in monetary terms.

Many pre-Industry 4.0 dosing pump systems

incorporate some form of a fault-logging

system, with the drawback being that these

are not always checked regularly, let alone

actioned. This is often a consequence of

the reactive “if it is not broken, do not fix

it” philosophy, where apart from minimal

maintenance, equipment may be left to run if

there are no visible issues and processes are


Now, IIoT-based systems enable users to

receive smartphone notifications as soon

as faults occur, meaning defects can be

quickly identified and remedial action can

be scheduled to take place outside normal

operating hours, when disruption can be

minimised. This yields an improvement in the

efficiency of equipment maintenance, repair

and upgrade planning, while avoiding costly,

inconvenient and unplanned downtime.

As well as overall system health, IIoT

technology allows for the performance and

status of specific pump components such

as bearings, couplings and belts to be

assessed. This means that the operator can

be alerted quickly should a part be due for

replacement, facilitating maintenance while

also driving aftermarket sales for suppliers.

Meanwhile, this component and system

data allows manufacturers themselves to

benefit from IIoT by monitoring trends, user

preferences and common problems, all to

refine equipment and continuously improve

their product offering.

It is not only the efficiency of equipment

and utilities that can be improved. For

businesses running across multiple sites in

different countries or even continents, IIoT

and the leveraging of real-time data means

operations management can be carried

out anywhere in the world and still be as

effective as they would be while standing in

front of the machine’s controller.

An example of how this technology could

be implemented can be seen in Elektra.

Elektra is an IoT-enabled digital controller

produced by Seko, a manufacturer of

chemical dosing systems for multiple

industry sectors, including the design,

production and supply of equipment

for processes such as potable water,

swimming pool water and cooling

tower water treatment. Elektra allows

operators of water treatment processes

to programme their equipment, as

well as access live and historic dosing

pump data on demand from any

location via smartphone. This allows

managers working remotely to analyse

pump performance and make instant

programming adjustments to save energy,

water and chemicals, while reducing the

environmental impact of their application.

The ability for one operator to remotely

manage pump systems across multiple

sites may also be useful for addressing the

water treatment sector’s well-reported lack

of skilled technical personnel caused by

retirements in an ageing workforce 2 .

This is especially true for water treatment

systems in smaller communities, where

lone, long-serving operators may possess

extensive knowledge of idiosyncratic

systems that may not be recorded or

documented. In those situations, a sudden

retirement, illness, or period of extended

leave has the potential to impair system


Additionally, wasted journeys by technicians

— who may travel a considerable distance to

assess a pump’s condition as part of routine

maintenance, only to find it in perfect working

order — can be minimised, as engineers need

only be deployed when required.

This is particularly timely post-COVID, where

the trend of remote working established

during the pandemic has seen many

operators continue to work at least partially

from home. The integration of IIoT is thus

starting to be seen as an expectation, rather

than a bonus.

The influence of IIoT on the pump industry

is positive and as technology advances, will

seemingly make life easier for operators.

However, as with most devices, connecting

pump systems to the internet immediately

makes them vulnerable to cyber-attacks,

where just one security breach can have a

potentially devastating impact on safety, cost

and reputation.

It is therefore vital that equipment

manufacturers employ robust processes

when designing secure products and back

them up with training and ongoing support for


At a time when 5G is opening yet more

possibilities for high-speed, reliable IoT, the

global pump industry is primed to see where

technology will take Industry 4.0 in 2022 and

Compressed air has an important role

in clean water supply and wastewater

treatment where different pressures

and degrees of purity are required. In

a collaboration with Belgium’s Waterlink,

BOGE equipped the Spaarbekken

Eckhoven reservoir with an aeration


The plug-and-play container,

constructed at the BOGE facility in

the Netherlands, was fitted with two

frequency-regulated 22kW BOGE screw

compressors with a control range

of 1.47–4.58m³/min and a maximum

system pressure of five bar, placed at

an outdoor location. The compressed

air passes through the refrigerant dryer

to dry the air to a pressure dew of +3

degrees, and then through BOGE’s

Bluekat converter to provide oil-free

compressed air which is pumped into

the water through five-point aerators.

The aeration ensures good mixing,

leading to increased oxygen content,

reduced release of nutrients by the soil

and elimination of dead zones. This,

in turn, limits the possibility of floating

layer-forming cyanobacteria and

assures safe drinking water.


Producing everyday goods generates

wastewater, which needs to be

treated before being discharged into

rivers and lakes. Not only does this

use a lot of energy and chemicals,

the process is costly. In Norway,

EffiSludge for LIFE (EFL) has found

a way to clean industrial wastewater

with environmental and climate

benefits. EFL developed an integrated

wastewater treatment method that

takes an “industrial symbiosis”

approach where the waste from one

sector becomes a resource for another.

They set up a demonstration plant

in the Norske Skog Skogn paper mill

north of Trondheim where the existing

industrial wastewater treatment facility

was integrated into a biogas plant. It

now cleans wastewater from the paper

mill while biogas is generated from

both the wastewater and waste from

the fishing industry. The approach

requires less energy than traditional

cleaning methods. The waste sludge

generated can also be reused to

produce biomethane instead of being

burned or sent to a landfill. Chemicals

and energy use are reduced, providing

a cost-effective and greener

wastewater treatment solution. The

emissions reduction of up to 9,000

tonnes is equivalent to the amount of

carbon dioxide that one million pine

trees absorb each year.


The availability of safe and sufficient

water supplies is linked to how

wastewater is managed. Increasing

amounts of untreated sewage, combined

with agricultural runoff and

industrial discharge, have degraded

water quality and contaminated water

resources around the world. According

to the World Bank, globally, 80%

of wastewater flows back into the

ecosystem without being treated or

reused, and by 2025, two-thirds of the

world’s population are likely to be water


In recent years, societal and

environmental pressures have led to

a growing movement for the industry

to reduce its wastewater and to treat

it before discharge. Wastewater is

now regarded as a potential resource,

and its use or recycling after suitable

treatment, can provide economic and

financial benefits. The growth of urban

demand for water will require new

approaches to wastewater collection

and management.

“A transformative approach is

key to reversing the flow of water

contamination, with more awareness,

enhanced prevention, and wise

investments in new technologies,”

Amunugama said.

New technologies for climate-risk

analysis are coming into the market that

can deliver insights at scale, assess

climate impacts on businesses and

support effective board-level decisionmaking.

These are useful both for water

management and the facilitation of

accurate and timely water-risk reporting

for businesses.

the deterioration of water quality in buildings

is directly attributable to stagnation. Recent

studies from microbiome research show that

just 12 hours of stagnation is sufficient to

cause an increase in bacterial numbers*.

During periods of stagnation, prolonged

contact of drinking water with the piping

system materials such as the pipe, valves,

and fittings can lead to a concentration of

nutrients via migration from the material

components into the water itself. A

combination of poor material quality — such

as material that does not conform to BS EN

16421* or WRAS regulations* — stagnation,

and unfavourable water quality can promote

a strong biofilm development*, in which

opportunistic pathogens — characteristically

called opportunistic premise plumbing

pathogens (OPPPs) in international

literature — can multiply. Stagnation creates

propagation advantages for these OPPPs, as

there is no dilution or removal of the nutrients

or planktonic micro-organisms entering the

water body. Nutrient discharge from materials

in contact with drinking water must thus be

reduced as much as technically possible. It

is thus the responsibility of the designer and

installer that all materials have been checked

and approved for their “microbial suitability”

for the water installation.

In addition, the effects of environmental

temperature should be considered. During

stagnation phases, the temperature of the

water will adapt to the temperature of the

ambient air surrounding it, even with standard

insulation of the pipes. This becomes a

problem when the surrounding ambient

temperatures are in the optimal propagation

range of the pathogens. Low temperatures

provide the pathogens with poor or no

growing conditions. Temperatures close to

the growth optimum allow for rapid growth.

pipes, heating circuits and other heat sources

such as electrical and ventilation technology

and the improvements in building thermal

performance, provide for air temperatures

which are significantly higher than 20°C. The

water content of a cold water pipe installed

here, even with insulation in accordance with

BS 5422, is heated to ambient temperature in

a short stagnation phase. With the installation

standards common today, it is expected that

after a period of stagnation, overheated cold

water with temperatures much higher than

20°C will flow from the tap for a significant

period of time. In accordance with BS 8558,

the cold water must be less than 20°C within

two minutes of running an outlet. If the

temperature of cold water is not below 20°C

within two minutes, the usability of the cold

water installation, according this regulation,

is no longer given. In addition to the abovementioned

internal heat loads and the impact

of improved building thermal performance,

incoming mains temperatures above 25°C

are expected to be more of a problem during

summer, due to higher temperatures from

climate change*.

To provide the consumer with compliant

cold water temperatures in the future,

conventional installation habits should first



be fundamentally reviewed. So-called

passive measures should be taken

in the first step. There should be

measures for a consistent thermal

decoupling of the cold water pipes

from heat sources whenever possible.

Planning measures should be taken

to reduce or interrupt heat transfer

through radiation, conduction, or

convection, from heat sources to

cold water pipes. However, thermal

decoupling of the cold drinking

water pipes from potential heat

sources is not always easy to realise,

particularly with horizontal distribution

if water consumption is too low,

heat absorbed from the cold water

Cold water circulation was first

realised in the main distribution

lines of cruise ships. In Germany,

numerous pilot projects have

delivered positive results in terms of

functionality and cost-effectiveness,

while achieving a mostly permanent

circulated temperature for cold

drinking water below 20°C.

For a cold water circulation

system to be implemented in

conventional plumbing installations,

an additional piping system must

be set up. This is not necessary in

installations that contain flowsplitters,

as the loop piping system

already available for the forced

flow water exchange can be used

for the water circulation. Existing

Kemper KHS systems can often be

switched from flushing technology

to cold water circulation with little

effort, as shown in Figure 1.

In contrast to conventional single

pipe cold water installations, flowsplitter

installations enable good

temperature control in all parts of

the pipe, right up to the connections

of the outlets.

Calculations with German insulation

standards taken into account show

that due to the small temperature

differences between the ambient air

and the cold water, the heat input

— and thus also the performance of

the required refrigeration unit — is

relatively low, only up to 3W/m pipe.

The KHS Coolflow cold water cooler

from Kemper, as shown in Figure 2,

removes the heat from the heated

cold water and dissipates it.

The pre-assembled compact unit with

integrated pump contains the required

components for cold water circulation

and cooling, in addition to being

diffusion-tightly insulated and preconfigured.

It can be connected to

existing cooling systems in buildings,

or connected to a KHS CoolFlow

Chiller, as depicted in Figure 3.

In hot water circulation, the

temperature differences between

the water temperature and the

ambient temperature are high. A

higher circulating flow rate is thus

required to maintain the required

temperatures. By contrast, the

temperature difference between cold

water temperature and the ambient

temperature is much lower. Volume

flows required for temperature control

in cold water circulation systems are

therefore rather low. For this reason,

the regulating valves required for

hydraulic balancing have a very low

kV value. In addition, the increasing

concentration of water constituents

must be counteracted by a targeted

water exchange during prolonged

circulation operation without water

withdrawal. Kemper has developed a

special valve in which the functions of

flushing, regulating and shut-off are

combined, as shown in Figure 4.


To reduce the ambient heat transfer to

cold water systems, passive thermal

decoupling measures should first

be used. Even with good thermal

decoupling measures, during

summer months with incoming water

temperatures above 20°C and room

air temperatures above 25°C, the

temperature of cold water is expected to

rise above 25°C. DVGW water information

90, BS 8558, HTM04-01 and other

international regulations agree that a safe

temperature for cold water is considered

to only be below 20°C. Passive measures

alone are not sufficient to achieve this.

An active process is therefore required

to ensure that a temperature limit for

cold water is met by the operator at

any time. Cold water circulation and

cooling combined with a flow-splitter

installation is recommended as an

optimal and cost-effective solution.

With products like the Kemper CoolFlow

system, a pre-determined temperature

of cold water of below 20 °C can be

mostly ensured at any time, right up

to each tapping point, even during

summer and without water losses, due

to temperature-based flushing. Together

with solutions for the circulation of the

hot water, water hygiene can be ensured

in both cold and hot water services.

Such solutions can be considered a

part of a proactive, preventive regime

that avoids hygienic deficiencies within

these water services. It is recommended

that planners and manufacturers

agree clearly with the client on which

temperature requirements for cold

drinking water should be met. On the

basis of this agreement, appropriate

passive and active measures have

to be planned and implemented in a

structural manner. If water installations

are built without active processes for

temperature monitoring and control, it

can be assumed that valid temperature

requirements from relevant regulations

can no longer be met in the future.

Inaction on reducing NRW will only

imperative that governments prioritise

sustainable long-term NRW reduction plans.

Through Infrastructure Asia and the World

Bank Group’s regular capacity-building

programmes and identification of suitable

financing and technology solutions to

address regional NRW, we have identified a

three-enabler approach that governments

can adopt to guide their NRW programmes.


Firstly, top-level management support is

crucial to set clear strategic targets and

advocate NRW reduction programmes

to all stakeholders. NRW reduction is a

long-term commitment, and a combined

effort from stakeholders at different levels

is needed.

Utility authorities should then establish

a dedicated and permanent team to

develop future-ready NRW reduction

roadmaps. This team will sustain progress

by prioritising implementation efforts

and deploying suitable investments. To

ensure the programme reaps maximum

benefits, this team should be entrusted to

monitor success and appropriately adjust

investments where necessary.



Given these responsibilities, the programme

needs a team that has the capabilities to

oversee the entire water infrastructure

lifecycle. Utility authorities should aim to

build capacity in the areas of law, regulatory

frameworks, project planning, technology and

technical capabilities. Regular collaboration

and investment co-sharing across public

utilities will also be beneficial in building these



Selecting the right mechanisms to resource

this strategy can also strengthen NRW

reduction outcomes and programme

management. Utility authorities should make

informed decisions on financing tools based

on project requirements, public-private

partnerships and risks. Facilitators like

Infrastructure Asia can intervene by bringing

together experts from relevant domains to

help bridge financing gaps.

Developmental financing is a useful

foundational tool to consider. Development

finance institutions (DFIs) such as the World

Bank Group and the Asian Development

Bank provide helpful mechanisms such

as equity participation, guarantees and

technical assistance to fund NRW reduction

programmes with high risk.

To further plug the financing gaps, utility

authorities with strong public-private

partnerships can explore private sector

financing to form a blended finance model.

By tapping on high liquid international private

capital such as the Climate Invest Two (CI2)

fund, utility authorities can appropriately fund

activities along the water infrastructure value


Another mechanism is performance-based

contracting (PBC), which incentivises private

companies to deliver NRW outcomes more

efficiently and innovatively by granting

contractors more flexibility in implementing

solutions. Through this option, contractors

are reimbursed based on their NRW

programme performance. This option was

utilised successfully in Ho Chi Minh City’s

NRW reduction efforts, with the city saving an

impressive 122 million litres of water daily.


Utility authorities can also explore applying

technologies such as artificial intelligence (AI)

or machine learning to water production and

distribution. Utility authorities should evaluate

current processes and identify digitalisation

opportunities, as doing so can improve NRW

programme outcomes such as operational

efficiency, monitoring accuracy and cost


There are many exciting potential

applications. For example, digital control

systems and AI can improve the productivity

of monitoring teams by identifying big leakage

points and prioritising pipe rehabilitation

efforts. Commercial losses can also be

reduced by using digital water meters and

online data monitoring services to monitor

meter performance and functionality more

closely. Finally, sensors could be used to

improve pressure management by modulating

water supply and ensuring maximum asset



To demonstrate the strength of this approach,

utility authorities can learn from Indonesia’s

Malang City. In exemplifying the three-enabler

approach, the East Javan city was able to

reduce NRW by 30%. This amounted to

savings of more than 70 million m 3 of water

and about $24m in revenue in 10 years,

improving citizens’ access to potable water.

Malang City’s utility authorities, known as

Perusahaan Darah Air Minum (PDAM) Tugu

Tirta, first received strong management

support to formulate a 10-year plan and

roadmap. The PDAM secured more than

5bn rupiah (US$4m) to begin the

transformation of the city’s water

infrastructure and facilities.

A team with relevant capabilities was also

created. With experience in deploying

infrastructure digital solutions, they worked

with private sector partners to set up virtual

distributed meter areas (DMA) in critical

zones. This allowed them to digitalise their

assets, enabling real-time monitoring of water

leakages to prioritise leak repair efforts with

minimal manpower.

Following its initial success, the PDAM

Tugu Tirta further optimised its operational

efficiency by setting up a 24/7 command

centre and deploying sensor technologies

to better manage water pressure

management and detect active leaks. On

top of contributing to a lower NRW rate,

these digital capabilities enabled the PDAM

to decrease overall commercial losses by

speeding up water leakage fixes to just one



For many developing societies, water is

a crucial resource that needs to reach all

segments of society safely and sustainably.

Ideally, it should also deliver optimum results

for a country’s economy and infrastructure.

Reducing NRW is key to these outcomes.

Moving forward, it is important that utility

authorities around the world share knowledge

to address NRW and similar challenges.

Malang City’s has shown that there are many

valuable lessons to be shared with other

Asian cities, who can adapt them to solve

similar local issues. With that, Infrastructure

Asia and the World Bank Group will be

working closely together with more cities to

scale similar non-revenue water successes in

the region.

industrial demand is growing faster than

any other sector. Thus, if left unchecked,

India’s manufacturing sector will continue to

compound India’s water problems.

The seriousness of these issues can clearly

be seen in one of India’s largest cities:


Energy recovery devices, including the PX Pressure Exchanger and Ultra PX, can reduce the

energy costs of UHPRO processes

UNESCO’s 2017 World Water Development

Report has declared that “[i]n a world where

demands for freshwater are ever growing, and

where limited water resources are increasingly

stressed by over-abstraction, pollution and

climate change, neglecting the opportunities

arising from improved wastewater

management is nothing less than unthinkable.”

Since that report five years ago, wastewater

management and treatment have only become

more critical. In fact, it could prove to be the

solution for countries like India seeking to

balance industrial growth with rising water


In 2014, India launched the “Make in India”

programme, with the goal of transforming the

country into a global manufacturing leader.

Before the pandemic, India’s manufacturing

sector accounted for about 17% of GDP.

Through efforts such as this and other

investments, India aims to increase industry’s

share of GDP to 25% by 2025.

Driving growth at this scale presents many

challenges, the chief among them being the

need for water.

India already grapples with challenges in

meeting water demand. The World Resources

Institute lists India as the 13th most water

stressed country in the world. The numbers

are stark: 600 million Indians face high to

extreme water stress, and about 200,000 die

every year from inadequate access to safe


Current estimates find about 70% of surface

water in India is unfit for consumption, with

Despite sitting between three major rivers,

Chennai increasingly relies on desalination

and water piped in from distant areas to meet

local demand. This is because the majority

of local water is contaminated, often due

to inadequate or non-existent wastewater


Currently, the vast majority of wastewater

goes untreated, with the goal is to implement

new solutions to improve the freshwater

supply and reduce pollution.

The chronic water shortage became a crisis

in 2019 when Chennai’s reservoirs ran dry

and city officials had to truck in 10 million

litres of water each day. This is hardly an ideal

situation for meeting the needs of everyday

citizens, nor is it supportive of ambitious

industrial growth targets.

However, there are new solutions available,

namely next-generation water treatment



technologies that can increase fresh water

supply while addressing pollution. Chennai

illustrated this through the adoption of

new regulations aimed at cleaning up

waterways and protecting groundwater

through greater use of minimal liquid

discharge or zero liquid discharge (MLZ/

ZLD) wastewater treatment.

MLD/ZLD technologies have advanced

significantly in recent years. However,

there has long been a major hurdle to

widespread adoption: the energy intensive

and costly nature of ultra-high pressure

reverse osmosis (UHPRO), which is at the

heart of many processes that meet MLD/

ZLD requirements.

New technologies like the Ultra PX are

changing this. The application of pressure

exchanger technologies can reduce the

energy needs of UHPRO processes, delivering

cost savings. For example, a lithium-ion

battery facility in China was able to reduce

energy consumption in the high-pressure and

ultra-high pressure treatment processes by

51% by utilising the Ultra PX and PX Pressure


The same technology drove major decreases

in the cost of high-pressure reverse osmosis in

affordable option, but also a game-changing

one. Indian cities like Nagpur have begun to reap

the benefits of industrial wastewater treatment:

a public-private partnership that embraced

industrial wastewater treatment for a power plant

reduced net freshwater extractions by the power

sector, freeing up freshwater resources for other

uses by around 47Mm 3 per annum.

The digital transformation of a

local water authority

By Lee Cher Hau, business consultant at YNY Technology

The water industry continues to face

challenges in serving its customers.

Some of these challenges relate to

droughts and floods which affect

many regions around the world and

represent the industry’s biggest


But there are other pressing issues as

well, ranging from water scarcity, high

energy costs, water quality, water

cuts and more. Take a look at nonrevenue

water — water produced and

lost before it reaches the customer.

There can be significant losses

through leaks or apparent losses

through metering inaccuracies.



Now, imagine that these challenges

could be anticipated and mitigated

against with a range of viable

solutions. What would this present

to us? This is where Industry 4.0

comes in, with a promise of increased

visibility and performance, all driven

by data.

The revolution is here, and it is present

in the ways that some companies are

running their businesses, in how they

create and deliver products and services

and make improvements throughout

their enterprise and their supply chain.

Progressive companies are integrating

and embedding new technologies such

as asset performance management,

edge computing, cybersecurity, artificial

intelligence, machine learning and data

analytics, all of which are helping them

change how companies deliver, interact

and respond.

Industry 4.0 delivers this promise

A digital command centre can be

utilised in a number of settings and

across different sectors. It integrates

multiple systems to correlate and

contextualise data. A real-time

optimisation system could be used

to provide real-time monitoring of

KPIs in order to respond accurately

to various scenarios. It could even be

used for mobile applications, especially

in a maintenance environment. In a

manufacturing environment, it can be

used to ensure production compliance,

product traceability and job execution.



Let us examine how one of our clients (a

local water authority in Malaysia) achieved

sustainable development through a digital

command centre solution.

As a local water authority, our client

relationship between

water, energy, food

and materials

Water, energy, food and materials

are the basic building blocks for

human survival and progress. Since

the industrial revolution, these

raw materials have enabled mass

manufacturing, rapid urbanisation

and economic development. These

elements are closely linked to one

another and form a complex nexus

of relationships. For example, water

is used in the urban environment

for domestic, commercial, industrial

and urban farming activities. At the

same time, it is also used in energy

production, including a significant

amount in refineries. Often, how well

cities manage these resources has a

direct result on the city’s social and

economic well-being.

Fig 1 illustrates how each element is

involved with one another and how

the output generated from one can

be diverted into another. In many

cases, these four elements compete

for the same limited resources in

a city, including political attention,

policy priorities, land space and

budget allocations. Adding to the

complexity is the knowledge that

any decision made will affect the

climate and carbon emissions,


Starting as a sustainability

solutions provider, Ecosoftt has

enabled buildings and industries

to become more water-secure by

conserving water and recycling

used water in a decentralised

manner. This is made possible

through its concept of managing

water “from source to source, at

source” and “fit-for-purpose reuse”.

In its basic form, water sources

are diversified and used water is

treated at its source and delivered

back for reuse to its most viable


For example, sewage and industrial

effluent can be recycled for

cleaning, irrigation, landscapes,

urban farming, toilet flushing,

cooling tower make-up and

industrial production uses. The

cost of treatment and safety factors

will be taken into consideration

when matching recycled water

for reuse applications. Heavy

capital investments within the long

pipeline of distribution can thus be

reduced or deferred, while the load

on municipal treatment plants is




semiconductor plants, pharmaceutical plants

and food production plants.




Ecosoftt is now extending this Water WISE

Buildings and Industries model to close multiple

resources loops, namely energy, food and

material within the built environment, as seen in

Fig 4.

Fig 2: Ecosoftt’s

Water WISE Buildings

and Industries.


The inclusion of solar energy, along with other

renewable sources in the energy mix is now

commonplace. Initiatives are currently being

embarked on to develop hydrogen and other

cleaner sources of energy.

Besides finding more sustainable sources of

energy, there is potential to recycle energy by

tapping waste heat, which is plentiful in many

buildings and industries. For example, in many

factories, a lot of waste heat is generated

from cooling systems used. This waste heat

could be used to pre-heat water. There is also

potential in recovering energy from wastewater.

Improvements have been made to technologies

such as anaerobic processes, and they can

become commercially viable at smaller scales

in the future.


Buildings and industries are now capable of

becoming sites for smart urban farms and

locations for production of nutrients that can be

made from the waste they generate.

and Industries platform that aims to capture

every drop of water and used water to treat

and reuse. This is supported by a Smart

Water Management system that collects

critical data for monitoring, reporting and

decision making.

The solution can be scaled from a single

building to an estate, such as a residential,

industrial or mixed development estate. To

date, Ecosoftt’s solutions has been applied

in a range of residential, commercial and

industrial properties, including hotels,

office buildings, commercial laundries,

A smart urban farm like an urban hydroponics

farm can control for key crop growth factors,

including hydration, lighting, and nutrient

requirements. Using sensors to collect data,

operators can remotely control the facility’s

pumps, actuators, lights and other equipment

to make the appropriate changes to optimise

growth conditions.

Food waste management and reduction

represent another opportunity. The integration

of smart solutions enables audits and data



review to be conducted seamlessly.

Current technologies allow for the

accurate logging of food waste, based

on type and quantity. This allows

commercial kitchen operators to

access data for fine-tuning production

and tracking wasteful practices.

Any excess food waste can then be

converted to organic fertiliser for urban

farming, forming a symbiotic relation

between the two.

energy, food and



Solid waste from buildings and

industries have conventionally been

left to municipal waste sorting stations,

incinerators or waste at energy

plants and landfills. None of these

are sustainable in supporting our

demand on natural resources.

Here, new technologies are offering

new ways to address this difficult

issue. Catalytic pyrolysis offers

a potential means to sustainably

reduce the accumulation of plastics

within landfills. Through this process,

recovery of valuable energy products

such as oil and gas can be achieved

as well. Recovered hydrocarbon gas

products can be recycled and put back

into the process, essentially creating

a net-zero energy system. A potential

drawback of using pyrolysis is the

need to pre-treat the plastic feed by

washing and shredding it, all of which

involves the additional consumption

of resources. However, with good

wastewater management solutions and

generation of energy on-site, these

drawbacks can be minimised.

Another option is having an on-site

incineration installation, allowing the

conversion of material inputs and

wastes into ash and heat. This reduces

the volume handled, allowing for more

efficient handling and management

of material waste as opposed to

conventional collection schemes.


These resource management

strategies demonstrate that there

is much room for us to move away

from the “once-through model” to a

more circular approach in buildings

and industries.

In many cases, the technologies are

already proven and viable, or will

become viable in the foreseeable

future. For other technologies,

there is scope for innovators and

facility owners to collaborate in

developing and test-bedding

initiatives. With the rising price of

resources and increasing attention

to environmental, social and

governance goals, there is now

considerable economic incentives

for players across the value chain

to embark on circular management

initiatives. We have been presented

with mankind’s greatest challenge,

as a result of our own doing. But

we are hopeful that we have the

ingenuity to solve this problem.

Charles Dickens’ famous

words may aptly describe the

circumstances that we are in: “It

was the worst of times, it was

the best of times, it was the age

of foolishness, it was the age of

wisdom.” May wisdom prevail and

the best of times continue.

slices away inefficient

wastewater treatment

The AVANT MQC achieves smoother wastewater processes without primary treatment

Choppers pumps deliver smooth and

reliable wastewater treatment.

In wastewater treatment facilities, solid

waste frequently accumulates inside the

collection tanks, where they may clog

impellers and the pipelines. The clogging

of the pump becomes a major problem that

can cause overflowing and jeopardise the

effectiveness of the entire system.

Bar screens and filtering grids might not

be an effective option for all applications

as they require continuous monitoring and

periodic removal of accumulated solid

wastes. During cleaning, the system might

require a shutdown with a specialised

technician, increasing operating expenses.

Moreover, the varied properties of waste,

which range from fibrous long solids

and plastic, renders pumps with grinder

mechanism and low free passage size

unsuitable. Furthermore, the grinder

hydraulics have limited flow rates and can

often take a long time to empty the tank to

the safety threshold.

Tsurumi’s AVANT MQC series consists of

chopper hydraulics designed to handle

wastewater without primary treatment. The

system’s main component is a steel knife

with a sharp edge that skims the channel

impeller’s blades to cut solid objects of

any size and composition. This prevents

both the impeller from clogging and the

accumulation of residue in the pipe, ensuring

the system runs smoothly and reliably.

The blades provided on the open channel

impeller are constructed out of hard cast iron,

which, at between 450 and 500HB, is more

durable than grey cast iron. The material is

comprised of several different components:

chromium, molybdenum, nickel, manganese,

copper, etc. AISI 431 stainless steel, which

has a carbon content of less than 0.22%

and a hardness of around 300HB, is used

for the knife, making it strong against shear

forces. Furthermore, the design of the cutting

mechanism allows easy replacement of the

blade for severely fouled wastewater handling.

As the chopper pumps are equipped with

MQ motors, IE3 standard motor efficiency

is achieved to reduce power consumption.

Furthermore, as with all of the MQ-series, dry

installation of chopper pump is possible with

the option of DRY version MQ motors. DRY

MQ motors are cooled with a mixture of water

and glycol that circulates in a special closedcircuit

inside a special design of the doublelayer

stainless steel jacket. An axial impeller

is also provided in the coolant chamber

for effective re-circulation of the coolant,

ensuring continuous heat exchange between

the motor and the external environment. Even

in a partially submerged or dry installation in

a high-temperature environment, continuous

operation in the S1 service class is guaranteed.

MQC Chopper pumps can be used for a

wide range of applications, from municipal

wastewater treatment plants and sewerage

pumping systems, to livestock farms and meat

processing industries. It can also be installed

in pulp and paper mill lifting systems, and in

wastewater pumping systems for textiles and

tanning industries.

of making SWRO desalination more

efficient and sustainable.

compared to the PX Q300

(depending on plant size)

• Less than 3% volumetric mixing

• The lowest projected life cycle

cost of any ERD for SWRO


“With the PX Q400, we’ve further

innovated and improved upon the

reliable, field-tested, and trusted

PX models that preceded it,”

said Rodney Clemente, senior

vice-president of water at Energy

Recovery. “The PX Q400 enhances

efficiency, capacity, and value to

ensure Energy Recovery remains

the most trusted manufacturer of

ERDs in desalination.”

The PX Q400 is said to offer:

• The highest average efficiency

compared to other PX

technology products

• The highest capacity PX yet, at

400 gallons per minute (gpm),

resulting in 25% fewer devices

Made with corrosion-proof

ceramic and designed with only

one moving part, the PX Q400

supports a 25-year design life

with no scheduled maintenance,

leading to low life cycle costs and

maximum uptime.

The PX Q400 is the new flagship solution in

Energy Recovery’s PX family of products.





The OpreX Magnetic Flowmeter CA Series,

as released by Yokogawa Electric Corporation.

magnetic flowmeter series

The Yokogawa Electric Corporation has

announced the release of the OpreX Magnetic

Flowmeter CA Series. This new product series

succeeds the ADMAG CA Series and is being

released as part of the OpreX Field

Instruments family. The products in this new

series are all capacitance-type magnetic

flowmeters that are capable of measuring

the flow of conductive fluids through a

measurement tube without the fluids coming

into contact with the device’s electrodes.

In addition to this non-wet electrode

construction, this series features new

functions that improve user-friendliness,

maintainability, and operational efficiency.

The new series is now available in most

major markets, such as Japan, South East

Asia, North and South America, Oceania,

the Middle East and Africa. It will also be

launched in Europe and China after qualifying

for CE marking and obtaining the relevant

certification for explosion-proof standards.


In plants, inspection is required for

each instrument to maintain stable

operation and product quality, so the

efficiency of such inspections is an

ongoing issue for production sites. As

magnetic flowmeters have no structural

components that hinder the flow of

fluids and cause a loss in fluid pressure,

they are used in plants to measure

fluids with conductive properties. Large

chemical plants and other such facilities

can have hundreds of these instruments,

so it is important that the inspection

and replacement, as well as the

collection of the data from each of these

devices can be carried out efficiently.

In response to these needs, Yokogawa

has revamped the ADMAG CA line-up

of flowmeters and developed the OpreX

Magnetic Flowmeter CA Series. The

new series is equipped with features

to improve operational efficiency and

maintainability for release in a range

of regions. This will help reduce the

person-hours required for customer

instrument inspections and contribute to

improved plant operational efficiency.



Capacitance-type magnetic flowmeters

utilise electrodes that are mounted

outside a ceramic measurement tube to

measure the electromotive force generated

by fluids passing through the tube,

reportedly minimising all direct contact

between the electrodes and the fluid. This

ensures a stable flow measurement of

fluids containing minerals that generate

electrical noise when they collide with an

electrode. Fluids used include latex for its

insulation properties, as well as fluids that

have low conductivity, such as deionised

water and mizuame, also known as millet

jelly. In addition to non-wet electrode

construction, the newly released OpreX

Magnetic Flowmeter CA Series has new

features such as support for Highway

Addressable Remote Transducer (HART)

communications protocol, a nine-language

user interface, device soundness analysis

functions to improve maintainability, and

easily replaceable measurement tubes to

suit a variety of purposes.

creation of Lacroix Environment, a

French-based technological company

specialising in creating smart products

for managing water and energy


The use of integrated input or output

(6DI/2AI and 4DO) and communication

interfaces (RS232/RS485, ethernet

and modem) make the product easier

to integrate into water applications.

The RTU’s compactness makes it

compatible for the following water

applications: pumping stations,

drilling stations, lifting stations and

water tanks. When needed, the

product’s modular architecture allows

users to add expansion modules

to fill requirements for wastewater

and drinking water treatment plant


The YDRIX RTU is also embedded

with water libraries, such as pumping

and lifting stations, to quicken

deployment and accelerate time to

market. The product natively integrates

a telecommunication modem to

allow usage on 2G, 3G or 4G telco

networks. This integrated modem

facilitates the deployment of the

system by having a single product to

deploy, instead of having an RTU with

an external modem. Maintenance

is also simplified through having a

single product to maintain and update.

YDRIX RTU is also compatible

with Sofrel dataloggers and allows

direct communication between both

products. This provides complete

dataloggers and RTU systems to




YDRIX integrates a native

implementation of standards protocols.

This allows for inter-operability with the

transmission control protocol (TCP)/

internet protocol (IP) networks, as

well as to operator supervisors, by

using the standard DNP3 and IEC

60870-5-104 communication protocols

over TCP/IP networks. Integration

into existing networks is thus more


The product can also reportedly

interface directly to any supervisory

control and data acquisition

(SCADA) system, such as WinCC or

Wonderware, meaning that the RTU

can fit into a pre-existing telemetry and

SCADA network.



YDRIX RTUs are “full IP”, meaning

they can communicate via their 2G,

3G or 4G modems or their ethernet

links to the SCADA central station.

These multiple systems allow for

redundancy among the communication

media. In the event of failure on the

main telecommunications network, the

Sofrel YDRIX automatically switches

to secondary support and returns

to normal when the initial network

becomes operational again. Operators

can thus rely on this system to prevent

the loss of information and recover

network data in real time.

The Sofrel YDRIX can secure the

overall system with user management

implementation. This allows operators

to grant authorised access to the

product solely to approved users. The

user management system also allows

operators to provide different access

permissions, such as read-only,

configuration and administration.

The product is also embedded with

a VPN client. With this VPN client, it

can connect to a VPN server using,

for instance, Open-VPN protocols.

This connection allows for the data

exchanged between the two structures

to be fully encrypted, ensuring

infrastructure security.





The new COOL-FIT 2.0

Push System

cover the last metre between COOL-

FIT 2.0 and the cooling unit.

The COOL-FIT 2.0 Push System

now bridges the gap by extending

the product range with smaller

dimensions. Designed for

temperatures between 5-60°C,

it includes sizes from d16 to d32.

Based on the iFIT range from GF

Piping Systems, the COOL-FIT 2.0

Push System offers a plug-and-play

installation through mechanical

connections, bendable pipes, and

modular adapter technology.

The COOL-FIT 2.0 from GF Piping

Systems was said to have changed

how people planned, installed and

operated cooling applications. The

pre-insulated plastic piping system

is corrosion- and condensationfree

and can be installed in cooling

applications in commercial and

residential construction, data centres,

or process cooling. With the addition

of the COOL-FIT 2.0 Push System,

it has become a complete solution:

additional dimensions cover the last

metre between the main pipeline and

fancoil or air handling unit, leading to

higher energy efficiency and a more

reliable operation.

Air conditioning (AC) technology is

becoming increasingly important.

The new COOL-FIT 2.0 Push System bridges

the gap between the main pipeline and the

cooling unit by extending the COOL-FIT range

with smaller piping dimensions

The number of air conditioning units

in buildings is estimated to reach 5-6

billion by 2050, due to climate change

and rising population numbers. At the

same time, high-tech industries rely on

AC for process cooling applications,

such as data centres or manufacturing.

As a result, the need to reduce CO2

and greenhouse gas emissions is

greater than ever.

GF Piping Systems aimed to address

this challenge by developing a

pre-insulated three-in-one piping

system for chilled water, including

pipes, fittings, valves, and tools.

This complete system has seen use

in comfort cooling and a range of

commercial and industrial applications.

Customers have previously relied on

pressed and welded metal systems or

post-insulated polyethylene pipes to

Made of lightweight materials,

COOL-FIT 2.0 is a corrosion- and

maintenance-free alternative to

metal piping systems. Furthermore,

these material properties mean that

the system can operate for 25 years

without interruption. Its three-in-one

design, consisting of pipe, insulation,

and robust jacket, combined with

efficient and easy jointing technology,

can result in a 50% faster installation

time than post-insulated metal pipes.

Due to pre-insulation and the use of

plastic, COOL-FIT 2.0 also minimises

pressure losses and has low thermal

conductivity, making the system 30%

more energy-efficient.

“We have already shown that plastic

piping systems are a long-lasting,

easy-to-install, and high-performing

solution for a wide range of cooling

applications,” said Kevin Blumberg,

senior business development

manager cooling at GF Piping

Systems. “Introducing the COOL-

FIT 2.0 Push System is an important

step forward; we can now bridge

the gap to the cooling unit for our

customers. COOL-FIT is a complete

solution for confident and safe

insulation that makes commercial

and industrial cooling more energyefficient.”
