FROM THE EDITOR

THE WATER UNDER

THE BRIDGE

Time and time again, the global water system

undergoes serious tests and strain — from the

effects of climate change, to water scarcity,

and issues with sanitation. These challenges

have shifted the how we come to understand

and interact with water as a natural resource

and necessity in our daily lives.

However, the water industry has persisted

even in light of these obstacles, pushing

forth and deriving novel ways that adapt and

overcome these issues. From nanofiltration

membranes to digital monitoring systems,

these innovations have allowed water utilities

to continue in their pledge to deliver safe

and sanitised water to the public, as well as

the close study of water bodies to safeguard

future use.

In the city of Paris, the upcoming 2024

Summer Olympics have mandated the need

for sanitised water supporting its people and

participating athletes. With the ColiMinder

from VWMS, Eau de Paris — the city’s water

authority — is able to track sanitation levels in

the waters of the Seine, as well as detecting

contamination in a timely manner (p. 18).

loggers monitoring water levels, utilities can

act efficiently in their understanding of the

Great Fen (p. 20).

As water management rises to a greater

undertaking, the need for tighter

collaboration has become more important

than ever, requiring a comprehensive

hand that tackles as aspects of a system.

Arup’s Design With Water 2.0 promotes

an outcomes-led approach, focusing on

shared values, rethinking assets, and new

stewardship models (p. 36).

With the 2030 deadline of the UN Agenda

for Sustainable Development looming

ahead, there is certain confidence that all

parties, from private to public, are wellequipped

to face future challenges ahead.

At Water & Wastewater Asia, we continue to

deliver the best and sharpest responses to

the great water challenge, highlighting the

best that the industry has to offer.

AQUAPORIN ANNOUNCES COLLABORATION

ON NOVEL DESALINATION AND

WASTEWATER PILOT PROJECT

A collaboration between Aquaporin,

University of Las Palmas de Gran Canaria,

and Canary Islands Institute of Technology

will develop a forward osmosis pilot plant

based in Mancomunidad del Sureste de Gran

Canaria.

The pilot project aims to combine

desalination and wastewater treatment

to ensure sufficient clean water supplies

in areas lacking naturally sourced water.

Aquaporin will provide its membranes and

knowledge of its forward osmosis technology

and processes. The collaborators will guide,

train, and educate each other with the goal

of combining desalination and wastewater

treatment processes.

The collaboration with provide access

to knowledge that will advance the

technological development of the proposed

solution. The knowledge gained from testing

will be used to facilitate a more sustainable

water management in the Canary Islands,

which will also be a good example for other

island communities with similar water scarcity

issues.

The Aquaporin Inside membranes will ensure

minimal cross-contamination and high

efficiency on an island where circularity and

reuse are of utmost importance to address

water scarcity issues.

Desalination facilities are common around

the world where access to naturally sourced

drinking water is scarce. This means the pilot

project has the potential to be a global solution

for areas where seawater is the primary or only

source of water.

Aquaporin’s vice-president of open innovation,

Jörg Vogel, said: “The collaboration with

University of Las Palmas de Gran Canaria and

Canary Islands Institute of Technology is a

great example of where combining different

technologies with forward osmosis has the

potential to make a significant difference,

and it is our belief it will further strengthen

Aquaporin’s position in the market.”

The concept of open innovation is a

cornerstone in Aquaporin. This is best shown

through the circular thinking of their initiatives

Aquaporin Academy, Aquaporin Garage,

and Primer, where Aquaporin is welcoming

students, supporting startups, and creating a

bridge between art and science.

A collaboration with University of Las

Palmas de Gran Canaria and Canary

Islands Institute of Technology supports

Aquaporin’s commitment to open innovation.

The research, development, and innovation

project allows Aquaporin to exchange

and train key resources and enables the

development of a final solution to combine

desalination and wastewater treatment which

can be commercialsed.

The collaboration is set to last for two

years from July 2022 with the possibility of

extension.

3E-NF HOLLOW FIBRE

NANOFILTRATION MEMBRANE

delivers heightened and

efficient performance

Suited for use across the water and wastewater

treatment industry, the 3E hollow fibre

nanofiltration membranes offer significant

benefits to operating systems.

With that, Fu set out to tackle these issues

through hollow-fibre (HF) nanofiltration

membranes (NF). 3E’s HF NF membranes

products, launched in 2019, are the world’s first

HF NF membranes that have achieved largescale

production with low energy consumption,

customised salt rejection rate, elevated

operation temperatures, and significant

oxidation and fouling resistance. Applications

for the membrane include municipal and

industrial wastewater recycling, cooling tower

water treatment, direct drinking water, seawater

reverse osmosis pre-treatment and zero liquid

discharge.

3E-NF membranes differ from the traditional

spiral NF membranes and some developing

HF-NF membranes. This is due to the rejection

of MgSO 4

found in these two membranes,

which are between 80-96%, making them

suited for only drinking water and the

production of NEWater. However, the 3E-NF

offers a wider rejection rate of 5-95%, allowing

it to be used across different applications,

ranging from seawater desalination pretreatment,

material separation to NEWater, as

well as the production of drinking water.

The membranes support wastewater recycling for cooling towers

Having served more than 20 years in the due to the dead-end corners in the feed

industry for embarking on a research

and permeate spacers of the spiral-wound

career, Fu Fengjiang noticed the existing configuration. Furthermore, these membranes

problems with spiral-wound reverse

demanded high operation pressure with high

osmosis (RO) and nanofiltration (NF)

energy consumption, and necessitated the

membranes: they were not only overtreating

the water, and thus making it

went into the RO/NF system; there was

addition of reductants before the feedwater

undrinkable by removing all minerals,

also a restricted product range for other

but they also had poor fouling resistance applications.

The 3E NF membrane offers the following

advantages compared to other types and

brands of NF membranes.

1. Unlike other HF NF coatings which can

be peeled off easily as glue to the skin,

the one-step 3E NF coating adheres to

the surface like a second skin;

2. Strong anti-fouling property with super

hydrophilic and smooth selective layer

surface;

3. High resistance to antioxidant

substances, this means chemical cleaning

can be used for avoiding biofouling;

4. Lower operation pressure and less

footprint

SINGAPORE FOCUS

MARICULTURE WATER RECYCLING

3E-NF membrane has been used for

seawater fish farm wastewater recycling,

laundry wastewater recycling, municipal

wastewater recycling for cooling tower

feed water, and more. In particular, the

membrane is suited for desalination pretreatment.

The 3E NF membrane module

Desalination plants generally use two types

of membranes: UF as a pre-treatment

to remove suspended particles, and RO

to remove the dissolved solids. The UF

membrane pre-treatment for the seawater

desalination is unable to remove hardness

and the majority of organic pollution, and

consequently the RO system is prone to

fouling and scaling. This leads to more

production downtime for the RO system

cleaning and maintenance as well. While

the water industry has been assessing

the removal of hardness through NF

membranes for a long time, no spiral-wound

NF membrane can replace the existing

UF membranes due to the space and flux

constraints.

On the other hand, HF NF membranes

improve desalination pre-treatment.

As they have the same configuration

as UF membranes and are capable of

removing hardness, they are a one-toone

replacement that will reduce the

overall capital and operating expense

of the desalination plants. With a wide

range of salt rejections to better suit

difficult feedwater qualities and permeate

standards, 3E NF membranes, can deliver

clean water with valuable ions preserved.

One of the company’s products was used in

a seawater fish farm to achieve low energy

water recycling in Singapore. Led by the

Singapore government and Singapore

Fish Culture Association, along with Ngee

Ann Polytechnic’s Environmental & Water

Technology Centre of Innovation, Aquarium

Iwarna, a marine ornamental fish import

and export company, cooperated with 3E

for the commissioning and installation of a

nanofiltration membrane wastewater reuse

system offering a 0.5m 3 /h capacity.

The system delivered the following

specifications:

• Feed: 38,000.0ppm

• Flux: 0.4±0.5 litres per hour

• Salt rejection: 20±0.3% (2000ppm

MgSO 2

)

• Operational pressure: 2.0 bar

With the 3E nanofiltration membrane, water

can be taken directly from the fish pond,

reducing equipment and overall operation

costs. More than that, the 3E-NF can

remove green algae via a variety of methods,

including backwashing, resulting in a more

stable system operation, in contrast to

conventional nanofiltration and reverse

osmosis membranes which are sensitive and

prone to the blooming of green algae in sea

water.

SUPPORTING WATER RECLAMATION

With up to 40LMH/bar flux, 3E-NF05

can also be used to achieve one-to-one

In another project, a 3E-NF05 HF

membrane system, with a 2,000m 3 per

day capacity NF-RO membrane system

design for cooling tower feed water, was

supplied, commissioned, and installed for

the Shangdong Kytoland Watertech. The

organisation had decided to use this system

in order to reduce demand of the Anqiu

thermal power plant for tap water, and to

preserve current drinking water resources.

After careful investigation, the 3E NF-RO

membrane was utilised in 2020 to treat

the reclaimed water, meeting discharge

standards; it was used for the cooling

tower’s water at the thermal power plant

after reaching the same standards as well.

With the NF-RO reclaimed water treatment

equipment, 3E thus attained its first

reclaimed water reuse project.

The system thus presented the following

parameters:

• Effective membrane area: 61.0m 2

Water flow rate: 128±0.5 ton/day per bar

• Operation pressure: Maximum 3.0 bar

• Salt rejection: 2000ppm; MgSO 4

: 10±1%

• Maximum free-chloride resistance:

1000ppm

With the 3E-NF membranes, the overall

system will be able to run in a more stable

manner with a low maintenance cost. This

is due to the compact surface which is

not easily polluted, while also offering a

membrane flux that is close to ultrafiltration

membranes. In comparison, ultrafiltration

membranes offer a molecular weight

rejection rate of more than 5000da, which

cannot intercept the hardness of and organic

matter in water, resulting in the scaling and

pollution of the back RO membrane.

In addition, the 3E-NF membrane can

be used in a variety of ways, including

backwash to remove biological pollutants,

among others; its operating conditions

are also similar to those of ordinary

ultrafiltration membranes. Altogether, the

use of 3E-NF has supported a more reliable,

stable and feasible reuse of municipal

wastewater.

SUPPORTING SUSTAINABILITY

Sustainability has been a hot topic across

the water industry, and with the deadline

for the 2030 UN Agenda for Sustainable

Development fast approaching, the call for

both the private and public sector to work

together is strong. On that front, Nanda

believes that the issue of NRW remains

pertinent to address unnecessary water

loss, which might exacerbate global water

scarcity. There is thus a need for water

utilities to upgrade their current pipelines

and infrastructure in terms of capacity

and distribution. This can be done through

the latest solutions offered by the water

industry.

Nanda added: “With digitalisation, water

utilities can use technologies such as

Grundfos’ Demand Driven Distribution that

intelligently adjusts water flow according to

demand through the use of remote sensors.

14 WATER & WASTEWATER ASIA | SEPTEMBER/OCTOBER 2022


IN CONVERSATION WITH

This reduces any excess water pressure,

which in turn limits water leakages and

losses.”

In Vietnam, solar arrays

provided a much-needed

update to the local water

infrastructure

In addition, it is also imperative for utilities

to diverse their water supplies. A circular

approach is one such way — by designing

waste out of the resource ecosystem and

maximising the value of resources, they

can be used for a longer time. Of this, water

reuse plays a large role. The treatment of

wastewater such that it can be fed to our

water cycles can be vital in times of scarcity.

Nanda noted that water treatment solutions

now are capable of empowering companies to

reuse their wastewater, reduce costs, and do

their part to ensure that natural water sources

are not unnecessarily exploited.

“However, innovation can come with a high

barrier to entry, especially for developing

countries. Most are unable to afford the

burden of these huge infrastructure costs,

while some see new innovations as an

expense rather than an investment,” said

Nanda.

With that, Grundfos Energy Earnings serves

as a payment service business model that

saves energy without requiring an initial

investment, allowing customers to finance

new pump solutions with a share of their

energy earnings. Nanda further shared that

with this, Cambodia’s Takéo Safe Water

Supply paid for themselves with about 15% in

energy savings.

“In a similar vein, availability of labour among

utilities is becoming a new challenge, more so

after the COVID-19 pandemic. Thus, we see

remote condition monitoring and predictive

maintenance will be levers utilities can use. In

response, we introduced Utility Connect few

months ago and are expanding this globally.

We see the strong relevance of this solution

for Asia Pacific region.”

WORKING SMART

At Grundfos, the company is committed to

developing and installing water efficient and

water reuse solutions. In Nanda’s words, the

company strives to optimise water solutions

at every stage of the operational water

cycle: water intake, water consumption,

water treatment, water reuse and water

replenishment.

He further shared that digital technology and

artificial intelligence have played a significant

role in helping the company with their

sustainability goals, through remote sensing,

asset management, predictive analytics, and

more. Digital innovations can play a vital role

in reshaping the relationship between humans

and water from a one-way direction into a

dialogue, said Nanda. With real-time sensors

and data analytics used for pre-emptive

checks and predictive maintenance, water

use can be approached with a more strategic

hand.

“One of our learnings was the need to

prioritise reducing our overall footprint,

including our end-users’ emissions while

using our own products and solutions. We

have also worked with internal and external

stakeholders to further our ambition of

contributing to safely managed drinking water.

We have become wiser in how we can define

contribution in a meaningful way and what our

main contributions are,” he added.

Notably, the company has also been diving

into renewable energy. These technologies

can help areas in Asia-Pacific where water

infrastructure is underdeveloped or outdated;

Can Duoc, in the Mekong River Delta region of

Vietnam, was one of such locations to benefit

from solar energy.

“With donations from the private sector, a

new water treatment plant, partially powered

by solar arrays and a solar control panel,

was built in the district,” said Nanda. “This

innovative solar-powered water treatment

solution now serves 3,000 households

in Can Duoc, delivering safe water to the

communities. The solar technology has also

been instrumental in saving energy for the

pumping station while lowering operating

costs — up to one-third of the electricity bill

— for the investors.”

THE LOCAL TOUCH

When it comes to Asia-Pacific, Nanda

acknowledged that the region has made

significant progress in sustainable

infrastructure over the years. However, the

Asian Development Bank has noted, in its

water development report, that national water

security in the region still faces challenges

due to uncontrolled urbanisation and lagging

rural development, vulnerability to weather

and climate events, and environmental

pressures.

“For Grundfos, our focus remains on bringing

innovative and sustainable water solutions to

the region. To achieve that, we will work more

closely with our end-users to understand

their needs better and develop more locally

appropriate and tailored solutions to their

unique water challenges,” explained Nanda.

One such way would be though digitalisation,

as the company works toward being a digital

solution and service provider and serving

end-users with system-focus and digital

offerings. On that front, the company is keen

on collaboration with partners and customers

to build a holistic water system while

balancing data security and connectivity.

Nanda concluded: “Utilities need partners

who can understand their problems, solve

them efficiently and create value for all

stakeholders. We need ecosystem-level

partnerships to solve these challenges, and

that is the approach we have adopted within

Grundfos that is aligned to our Water Utilities

SUEZ EMPOWERS

local and global needs

Pressing concerns surrounding the future of water has pushed many

water companies into playing their part for the sustainability agenda,

both regionally and across the world.

By Agatha Wong

Raising SUEZ as an example, Kaviani

explained that the company considers

climate change mitigation as one of their

core strategies for sustainable development

and business growth. With the aim to reduce

the impacts of climate change on water

treatment, promote recycling, recovery

and reuse, as well as developing climateresponsible

models, he noted that SUEZ

is equipped with the know-how on building

and operating self-sufficient wastewater

treatment plants. The company is also

capable of recovering carbon molecules from

wastewater for reuse, reducing consumption

of fossil fuels.

Today, SUEZ has a strong platform of 100 engineers and professionals in the Philippines, allowing the

group to respond quickly to the needs of clients in Southeast Asia.

The Asia-Pacific region has delivered

promising growth in the past few years, and as

the world enters the third decade in the new

century, it appears that the region will continue

to prosper. Rapid urbanisation and population

growth are some of the factors that have

propelled the water industry in Asia-Pacific to

greater heights.

On the other hand, the shadow of climate

change casts a dark pallor over the landscape

in this part of the world. With volatile weather

patterns ranging from prolonged dry spells to

persistent rainfall, a robust water infrastructure

is needed to fortifying the water needs of the

Asia-Pacific. On that vein, water companies

are thus strengthening their capabilities and

solutions to meet the needs of this everevolving

zone.

“Across the region, the water industry has

started to adapt with innovative solutions

to limit emissions, but we must still rise to

the challenge,” explained Farchad Kaviani,

managing director SEA at SUEZ. “There is

still a long way to go for the water industry to

reach the net zero objective. Technical and

digital progress in the industry has made

it possible to preserve resource thanks

to predictive tools which integrate climate

change issue, to implement wastewater

treatment solutions and to recycle water

resources, notably for industrial and

agricultural consumption.”

“While competition continues to increase,

there is a shift to operate and manage water

resources and facilities more wisely than

ever. The current demand is no longer in

building more new infrastructure but also

through developing new growth models

and technologies that are circular and

sustainable,” he offered.

WORKING HAND-IN-HAND

Indeed, with the blueprint for sustainable

and actionable change up ahead, there is

still much that water companies can do to

safeguard the future of the industry. Kaviani

suggested that organisations should “think

globally and act locally” in order to meet

decarbonisation goals. This could be done so

through making use of green energy in dayto-day

operations, as well as the integration

of water and energy in a global approach to

procurement.

16 WATER & WASTEWATER ASIA | SEPTEMBER/OCTOBER 2022


IN CONVERSATION WITH

In order to excel at the game of water

resilience, it is also essential that all parties

involved play their part. Kaviani maintained

that it is only through collaboration between

stakeholders that guaranteed success to

water and sanitation can be delivered. This

is in light of increasing water stresses and

the emergence of new technologies that

necessitates greater collaboration beyond the

public and the private sector.

Furthermore, as Kaviani added, private

companies such as SUEZ can support

these initiatives through their innovations,

technical expertise and digitalisation. In their

growing portfolio of projects that has seen the

company support the digital transformation

of the stormwater network in Singapore, to

operating China’s first water PPP in Macau,

and the monitoring of water leaks through

smart solutions in Brazil, SUEZ has played

a part in shaping the water infrastructure of

these countries.

However, technology is not everything, as

Kaviani reiterated: “We must rethink water

management models and adopt a long-term

approach on water projects management.

It implies a few fundamentals, namely

clear governance and stable legislation;

constructive dialogue with all stakeholders

with a local and long-term anchoring; and the

transfer of know-how and competencies.”

ATTUNED TO LOCAL NEEDS

As an example of how the future of a

sustainable water framework might appear,

SUEZ has supported a project with Manila

Water to promote wastewater development

in Metro Manila in the Philippines. The

company currently has an engineering

platform of over 100 engineers and

professionals locally to serve the country

and the region, tapping on SUEZ’s solutions

to provide drinking water and navigate

sanitation challenges effectively.

“Although the Philippines has sufficient

water resources, it was found that water

availability is still threatened by some major

water resources problems: increasing water

demand due to rapid growth in population,

water resources pollution, droughts, and

flooding (due to El Niño and La Niña) and

the need to strengthen its institutional

framework,” said Kaviani. “There is a

need to develop infrastructure that is more

cost-effective and technically feasible.

Infrastructure that can adapt to changing

water quality brought by climate change

(increasing turbidity and algae), compact in

view of the high cost of real estate in Metro

Manila.”

For the project, wastewater infrastructure

expansion was focused in Metro Manila,

where its concessionaires are planning new

municipal wastewater treatment facilities in

line with a wider government programme to

reduce pollution in the contaminated Manila

Bay, Pasig River, and Laguna Lake among

others. This, according to Kaviani, is aligned

with the national government’s objectives

to achieve 100% access to sanitation by

2028 (which will require an investment

of approximately $619 million per year

according to GWI).

“The overall objective for SUEZ and its

partners is to create cities and towns that

are resilient, liveable, productive, and

sustainable. We are exploring partnerships

with local stakeholders to support the

development of water infrastructure in many

provinces facing pressing water challenges,”

said Kaviani.

SUEZ is operating in

16 industrial parks in

Asia, one of which is

the Shanghai Industrial

Chemical Park zone in

China, where the company

celebrated its 20th

anniversary this year.

FOR THE REGION, FOR THE WORLD

Altogether, the Asia-Pacific region presents

unique combination of challenges for the water

industry to tackle. As it continues on its upward

climb towards greater economic success,

water companies can contribute to its growth

by ensuring a robust water infrastructure. At

SUEZ, the company remains adherent to its

environmental and sustainable while serving

municipals and industries in Asia.

“In the water and wastewater sector, we

identify four main areas to better support

the region – reducing pollution emissions for

industrial wastewater treatment; restoring

water ecology with projects such as river

remediation; treatment and reuse of sewage

or sludge and finally smart water, and other

concepts to improve the performance of water

and wastewater management.

“Amid widening recognition of how

environmental issues create business

opportunities and risks, SUEZ in Asia

continues to place preserving the environment

at the top of its mission priorities. We are

determined to protect the planet’s resources

from degradation, through concrete actions

that deliver excellent and continuous

environmental value. This remains the core of

our daily business, it is how we believe we can

have the greatest impact for the planet and its

people,” concluded Kaviani.

EAU DE PARIS GETS

A JUMPSTART

on water sanitation

The city of Paris faces a series of challenges in the years ahead: besides

meeting the needs of an urban population, they must prepare to meet

high water standards ahead of the 2024 Summer Olympics.

By Agatha Wong

With these monumental tasks, Eau de

Paris faced two distinct challenges: the first

challenge laid in the detection of faecal

contamination for the Seine or Marne River,

which supplies the water treatment plants. The

second challenge focused on the monitoring

of the quality of produced water in almost

real-time.

Furthermore, in lieu of the upcoming 2024

Summer Olympics, monitoring of the Seine for

triathlons and other swimming competitions

became necessary. The need for sanitary

water became prevalent as past Olympic

games saw significant E. coli contamination in

their natural waters.

With these concerns, Eau de Paris needed

a solution that will enable them to meet the

well as anticipating any possible challenges

that might arise in the city’s water facilities

during the 2024 Summer Olympics. The

water authority thus turned to VWMS, who

offered the ColiMinder as a candidate for their

demands.

THE RACE AGAINST CONTAMINATION

Fully automatic with a fast sample-to-result

rate of 15 minutes, the ColiMinder offers

specific measurement results for determined

indicator organisms such as E. coli and

enterococci. It is widely applicable across

different aspects of water and wastewater

treatment, ranging from drinking water, bottled

water, wastewater, process water, membrane

integrity, to surface and bathing water. For each

measurement, the ColiMinder provides three

results: The microbiological activity, which

reflects the degreee of contamination, the

transmission of the sample as a measure of the

transparency or turbidity of the sample, and the

intrinsic flourescence of the sample.

Depending on the reagent used, the

ColiMinder can measure the degree of faecal

contamination or total microbiological activity;

this parameter is used to monitor the quality

of drinking water, but also in mineral water

production. In addition, according to VWMS,

the system is very robust and low-maintenance:

consumables only have to be refilled every

1,000 measurements.

“We were very impressed by the reliability and

by the rapidity of the measurements,” shared

Dr Sophie Haenn, microbiology engineer —

R&D at Eau de Paris. “Its reliability was proven

through our own evaluation and validation of

the ColiMinder measurements, which were

conducted by parallel testing with traditional

culture-based lab method. The ColiMinder

results showed a significant correlation with lab

results.”

Dr Haenn further added that the flexibility of the

ColiMinder was a key factor in the authority’s

decision in choosing the system, as it can be

used in any water type: from drinking water

through surface/bathing water. The ColiMinder

has been shown to detect CSO (combined

sewer overflow) from a wastewater treatment

plant upstream the Seine River. For drinking

water, Eau de Paris is using the system not

only for raw water intake before chlorination,

but also for monitoring produced drinking

water after chlorination.

HEADED FOR THE FINISH LINE

The multiple benefits offered by the

Coliminder thus enabled Eau de Paris to

meet the needs of an urban population.

Where sanitation is concerned, the water

authority was particularly impressed that

the ColiMinder could produce results in 15

minutes, as contamination can occur very

quickly, posing a danger to the public’s health.

With the system installed, Eau De Paris

can now react swiftly in the event of faecal

contamination, allowing them to close the

water treatment plant until the contamination

has flowed through.

“For the moment, the Coliminder is mostly

used in research and in test installations at

different locations: at the entrance of our

water treatment plants to monitor the quality

of the water used to produce tap water, at

the exit of the water treatment plant before

chlorination. Our drinking water operators are

starting to understand that the ColiMinder

can be very important by providing the so

important information on microbiological

water quality in almost real-time, helping them

to improve their processes and make them

safer and more sustainable,” said Dr Haenn.

The installation of the ColiMinder has thus

enabled Eau de Paris to respond rapidly to

any possible contamination in their waters.

More crucially, the installation of this system

will assist the water authority to deliver

proper, sanitised water for the athletes and

participants of the 2024 Summer Olympics.

The quality of drinking water, but also the

one of water in urban recreation areas is of

high importance for the urban population. For

safeguarding this, the ColiMinder is a choice

solution.

“In times of scarcity, water has to be used

in a way that makes sense according to

its given quality,” said Dr Haenn. This was

proven through the second use of the water

networks in Paris — non-drinkable water

for street washing and irrigation. Though

the system had been out of use for almost

20 years, Eau de Paris was able to revive it

recently.

“Among other online instrumentation, the

ColiMinder has also helped us to understand

this network better. Thus, it has been revived

and we can now re-use water in respective

quality for street washing and irrigating

public gardens in Paris instead of using water

in drinking water quality for these tasks,”

revealed Dr Haenn. “Our team responsible for

drinking water also increasingly understands

how the ColiMinder can help to make

processes in drinking water production and

distribution more efficient, safer and thus

more sustainable.”

However, as Henry Stanier, monitoring

explained: “Nothing could be further

primarily on water levels, and this has

had a profound effect on the local

WBL: A DATA-DRIVEN

water authority

Data-driven operations can allow

water utilities to gain a deeper

understanding on their assets

and strengthen their abilities

to analyse past events and

anticipate future outcomes.

every day to show that things can be

done even better, and more sustainably

and efficiently.

However, turning their vision into a

reality was a significant challenge. WBL

knew that to achieve its goal it would

need to experiment with the latest

technological advancements, including

big data, digital twins and AI.

Like all water authorities,

Waterschapsbedrijf Limburg (WBL)

currently faces a wealth of challenges.

A growing population, strict EU

legislation, climate change and the

imminent retirement of an experienced

workforce are making it increasingly

difficult to meet the needs of its public.

As a result, the water authority

sought to implement data-driven

operations. Its goal was to gain a

greater understanding of how each

of its assets functions, and improve

its ability to analyse past events

and anticipate future failures and

emergencies. Working with Royal

HaskoningDHV Digital, WBL was able

to take a first step in realising this

ambition.

The project took place in the

Netherlands from 2021-2022, with

the challenge of setting up datadriven

operations with digital twins.

The solution was the creation of

a digital twin of their wastewater

transport system, consisting of

a big data platform and machine

learning models for early warning and

predictive maintenance.

EMBRACING DATA-DRIVEN

WORK

Waterschapsbedrijf Limburg (WBL)

is responsible for providing essential

clean water for 500,000 households

and 30,000 companies in the

province of Limburg, the Netherlands.

As this is a serious undertaking, the

water authority is driven to innovate

“The future vision of our company

is that we will become a data-driven

organisation,” said Léon Verhaegen,

senior project leader of ICT and

innovation at WBL. “That data-driven

organisation wants to know how all

assets function, as well as analysing all

past events to help understand them

and anticipate the future. The ultimate

goal, of course, is to anticipate the

future, and understand how our assets

will function in the future.”

EMBARKING ON THE FUTURE

TOGETHER

WBL chose Royal HaskoningDHV

Digital to implement these

technologies. With 140 years of

experience, in-depth domain

knowledge, and a team of ICT

infrastructure experts, the company

had everything needed to bring the

water authority’s ideas into the real

world.

24 WATER & WASTEWATER ASIA | SEPTEBMER/OCTOBER 2022


IN THE FIELD

The project began with Royal

HaskoningDHV implementing a

digital twin for all the water authority’s

sewage pumping stations. This digital

twin consists of a big data platform

that centrally stores data from various

sources, and machine learning models

that provide vital, real-time and

predictive information.

The insights from this digital twin are

managed in a central control room that

currently oversees 17 STPs, five sludge

dewatering plants, 149 WBL sewage

pumping stations and 800 municipal

pumping stations.

SMARTER, MORE EFFICIENT AND

FUTURE-PROOF

Armed with the insights from the digital

twin, the WBL water authority can

now detect problems in its pumping

stations early enough to take proactive

action and see if they are meeting

the purchase obligations of various

municipalities.

Melchior Schenk, business

development director of Royal

HaskoningDHV, said: “The digital twin

that we delivered to WBL consists

of a big data platform in which

data from various sources is stored

centrally and made available in a

standardised way for the machine

learning models in the wastewater

transport system.”

The digital twin uses machine learning

to detect at a very early stage that the

functioning of pumps is beginning to

deteriorate (eg due to wear and tear)

or that pressure pipes are in danger

of becoming blocked. The digital

twin relays these warnings to the

central control room, whereupon the

operators take action to prevent the

impending failures.

Jos Voermans, system engineer

PPA of WBL, commented: “We

now have up-to-date insight into

whether our pumping stations are

meeting the purchase obligations

towards municipalities. But it’s also

a learning process for us; we have to

manage the systems and set them up

properly. Moving forward, that means

the central control room will have to

deal with alerts differently.”

The preventative approach to

pumping station management makes

operations and maintenance smarter,

more efficient and more future-proof.

However the scope of this project

does not end there — if ambitions

are realised, this work could mean

not just big changes for WBL, but

the beginning of an industry-wide

transformation.

“In the future, we want to extend this

solution to 3,000 municipal water

stations,” said Verhaegen. “That way

we can gain real insight into how the

water chain works as a whole.”

“The most important thing we

achieved in this project is giving our

operators the tools and resources they

need to improve performance. That

hugely improves our efficiency and

emergency response.” emphasised

Verhaegen. “And the ultimate goal, of

course, is integrating all the data we

have so we can predict a pipe burst

of this nature and respond to it before

it happens. This will make operations

and maintenance smarter, and more

futureproof and efficient.”

LIGHTER TO HANDLE

AND LIGHTER ON

ENERGY COSTS:

Landia delivers

mixer to Fairfield

Smarter and greener solutions have enabled

the town of Fairfield, Connecticut to manage

their wastewater treatment facilities with greater

efficiency and energy savings.

Replacing anoxic zone mixers

with units that are far more energy

efficient is providing a water

pollution control facility (WPCF) in

Connecticut with annual savings

of US$22,433.

As it strides towards its goal of

achieving net zero carbon, the

town of Fairfield (population

60,000), wanted to reduce the

operating costs of its mixers that

run 24/7, as part of a major capital

improvement plan (CIP) to replace

ageing assets with more modern

and energy-efficient equipment.

“Like all treatment plants,” said

John Bodie, superintendent at

Fairfield WPCF, “we have been

a very big electricity user, but

when we reviewed our energy

usage and developed a full plan,

it presented us with an excellent

opportunity to adopt green design

standards.”

Similar to most treatment plants,

there is often unavailable budget

to comprehensively upgrade

equipment at the rate that would suit

best practice. However, as numerous

wastewater treatment facilities are

discovering to their benefit, grants

and incentives are available from

energy providers; in this case at

Fairfield with United Illuminating

(UI), a subsidiary of Avangrid, who

owns and operates a portfolio

of renewable energy generation

facilities.

ENERGY IMPROVEMENTS

AT LOW COST

Bodie, who has worked at Fairfield

WPCF for 30 years, added: “When

we plugged in the numbers, it all

added up; smart energy improvements

that would give us the greatest return

at the lowest cost, as well as big

savings for many years to come. The

help we had towards capital costs

from United Illuminating gave us every

incentive to go ahead. The 12 existing

mixers we had were never the most

efficient, and we also found them very

difficult to work on; mainly because of

how heavy they were.”

At the 8.5-million-gallons-per-day

facility, the mixers continuously

suspend solids and mix the return

sludge into the influent stream. The

existing mixing energy input met

industry-standard recommendations,

but the single-point submersible

propeller mixers left some dead

zones in the denitrification process,

as well as scum and foam formation.

It also required high levels of

maintenance and frequent rebuilds.

26 WATER & WASTEWATER ASIA | SEPTEBMER/OCTOBER 2022


IN THE FIELD

A USER-FRIENDLY OPTION

Bodie continued: “After looking at

several options, we initially invested

in six mixers made by Landia,

which came highly recommended

as the best solution. At 2.4HP each,

compared to the previous 6.5HP

units, we of course expected to see

a reduction in energy usage, but

the added bonus is that despite

being smaller, they do a better

job than the old mixers (from a

different manufacturer). The first six

mixers from Landia have now been

installed for just over three years,

with no issues at all. Previously,

when servicing a mixer weighing

considerably more than one from

Landia, we had to have three or

sometimes four men to manhandle

it to lift it out, and even then, it was

very easy for someone to suffer

a back strain. Now, with a Landia

mixer, it’s so much more userfriendly;

easy for just one person,

so that’s also made a big saving on

maintenance.”

with the Landia mixers, which provide

many cost and operational benefits to

Fairfield WPCF.”

In addition to the 12 new mixers,

the long-term energy efficiency

improvements also included a 2MW

solar system at the nearby former

refuse dump, and a 400kW fuel cell.

A new 1.3MW natural gas generator

was also installed, along with an

interconnecting switchgear, which

allows the WPCF and surrounding

town facilities to operate independently

in the event of power outages.

For Landia (established 1933),

this installation at Fairfield WPCF

follows a large number of projects,

where its submersible mixers have

replaced other manufacturer’s

inefficient or failing mixers. In some

cases, Landia mixers have been

installed in aeration tanks, to provide

mechanical mixing of sludge, while

reducing the aeration to just the

amount needed for the biological

process. In Chinook, Montana, two

5HP Landia mixers were purchased

so that a 50HP surface rotor aerator

could be switched off during night

hours of low BOD loading. As a

result, the submersible mixers are

now saving the wastewater treatment

plant $18,000 per year on electricity,

achieving payback on the entire

installation in just over four years.

A switch to Landia mixers has also paid

dividends at the wastewater treatment

centre in American Falls, Idaho. Here,

the original mixers failed to move

solids from the plant’s MBR — and

there were constant seal failures. Now,

despite only pulling half of the amps

than the previous units, the Landia

mixers, truly designed for mixing

wastewater sludge, have immediately

addressed the application – reducing

energy usage and are also proving

easier and more cost-effective to

maintain.

Following the success of the first

half-dozen mixers from Landia, a

further six were installed 15 months

ago at Fairfield, replacing units

from a separate manufacturer that

were also using too much energy

and proving time-consuming to

maintain.

SAVINGS IN ENERGY

“The mixers’ annual electricity

savings of over $22,000 equate

to a reduction in energy usage of

182,383kWh,” said Bodie. “The

WPCF was constructed here in

1950, with upgrades made in 1968,

1972 and 2001. It’s always been

a very well-run plant, but now the

CIP of four years ago can show

other treatment facilities what very

substantial savings can be made

in energy. We are very pleased

BIM TECHNOLOGY

OVERCOMES

limitations

The use of accurate 3D design and digital twins is critical

to constructing safe and fortified water infrastructures.

The Dongtaizi Reservoir project is a

CNY2.148 billion, large-scale water

conservancy initiative scheduled as

part of China’s 13th five-year plan

period. It is located in the middle and

upper regions of the Xar Moron River

in the city of Chifeng.

Liaoning Water Conservancy and

Hydropower Survey and Design

Research Institute was responsible

for delivering the engineering design

of the Dongtaizi Reservoir. This

project is one of 172 major water

conservancy endeavors meant to

tackle China’s water scarcity and flood

risk issues sponsored by the Chinese

government. Furthermore, it is one

of 12 key livelihood projects in Inner

Mongolia meant to mitigate severe

flood risk and combat water scarcity.

The proposed infrastructure was a

rockfill dam with an asphalt core wall

and a concrete gravity dam with a

total storage capacity of 321 million

cubic meters and a height of 43.5m.

At completion, the reservoir will

mitigate severe flood risk in the lower

reaches of the river and supply water

and agricultural irrigation to the areas

adjacent to bottom of the river basin.

CHALLENGING BOUNDARY AND

STRUCTURAL CONDITIONS

The surveying tasks and engineering

specifications on the Dongtaizi

Reservoir Project were immense.

The site’s complex terrain required

an accurate geological survey of

the rock mass foundation types and

structural plane upon which the dam

design would be based. A curved

ecological fishway that enables

migrating fish to pass through the dam

demanded significant excavation that

necessitated more than traditional 2D

processes.

Designing the rockfill dam section

involved many control conditions

and complicated interactions

with the landscape, which cannot

be solved with conventional 3D

modeling. Additionally, multidiscipline

engineering and visualisation

capabilities were essential to design

the metal structure, hydraulic

machinery and engineering, and an

electromechanical system. Therefore,

Liaoning Water realised that they had

to adopt building information modeling

(BIM) solutions to overcome traditional

design limitations on this large-scale

water conservancy project.

Using this project as the foundation

for BIM usage on future water

conservancy projects, Liaoning

Water has implemented corporate

3D collaborative design standards

and trained personnel to become a

regional leader in BIM application.

BIM APPLICATIONS OVERCOME

TRADITIONAL DESIGN

RESTRICTIONS

After considering their options, the

team employed Bentley’s BIM software

for accurate 3D design. Liaoning

Water integrated OpenBuildings

and OpenRoads Designer to

streamline collaboration among

multiple engineering disciplines and

to manage data. They surveyed the

landscape and created a detailed

3D geological model to precisely

calculate excavation volumes and

plan excavation processes. This

visualisation in OpenRoads also

allowed the project team to accurately

position the ecological fishway and

connect the structure’s complicated

spatial curve to the landscape.

The rockfill dam section was designed

using OpenRoads’ linear engineering

capabilities to generate a truthful

3D model incorporating all control

and boundary conditions. Several

engineering disciplines collaborated

on the design of the concrete dam in

OpenBuildings, allowing the hydraulic

machinery, metal structure, and

electromechanical equipment to be

designed to avoid collisions.

LEVERAGING BIM

TECHNOLOGY TO DELIVER A

DIGITAL TWIN

By using Bentley applications,

Liaoning Water reduced design error

by 90%. Delivering a technologically

advanced model minimised

changes to the overall design

during construction. Accurately

calculating project cost in the design

stage of the project decreased the

government’s overall investment.

With the support of open modeling

technology, the project team

improved design efficiency by 40%

to deliver the plans two weeks

ahead of schedule.

They leveraged BIM software

to produce a digital twin that

provided full lifecycle support of

the dam, including management

during construction, operations,

and maintenance. Bentley’s iTwin

contains everything needed for

implementers of building information

modelling (BIM) at construction

sites, collaborating with engineers

and others in the process.

Multidiscipline BIM teams can

review and update their work from

disparate models through the digital

twin.

Rather than a singular, centralised

model, having many individual

copies of models is optimal for

scalability and portability, given

that there is a way to keep them

all synchronised. The transactions

and the timeline of changes are

maintained in the cloud. This

timeline of change represents the

master digital record.

With the use of a digital twin, users

can benefit from:

• A visual, geo-referenced, and

federated information index that

supports easy accessibility and

maintenance for all relevant

engineering, asset operation,

and maintenance information,

supporting better decisions and

clearer communication.

• A review of the design bases

for engineering and operations,

with a view of the hydraulic

models, plant asset 3D models,

and associated engineering

information, defining “what

should be there” and eliminating

paper deliverables while

boosting performance on

commissioned systems.

• Easy updates and a timeline

of alterations to the asset,

capturing how and when the

engineering data changed,

as well as who made the

modification, so one could see

the impact of any alteration on

ongoing operations.

• A federated source of data for

all related systems. Visibility of

real-time equipment health and

condition degradation trends

is important for understanding

current performance and taking

the right actions at the right time.

• A unified view of asset health,

ensuring accurate information for

audits and course corrections,

as well as a complete and

consistent view of the system.

THE FUTURE OF BIM FOR

GREATER EFFICIENCIES

“The use of Bentley software has

solved the important and difficult

problems in the engineering design

of Dongtaizi Reservoir, provided

strong endorsement for designers,

improved the design efficiency of

our institute, reduced design errors,

and made the digital transfer of

design results possible,” shared

Wang Yixin, director of the digital

and smart engineering R&D centre

at Liaoning Water Conservancy

and Hydropower Survey and Design

Research Institute.

“A digital twin environment for water

infrastructure in construction is key

to enabling a fully integrated delivery

platform that is open and scalable.

Engineering and construction

industry professionals will never be

able to meet demand with legacy

tools and processes, and definitely

not with analogue tools. During

construction projects, engineers

spend about half a day each week

just looking for data. A digital twin

provides a single source of data

where stakeholders can collaborate

and manage field work, especially

The municipality of Steinen in the

southern part of the Black Forest uses

on average 1,800m 3 of drinking water

per day — half from deep wells and

half from around 30 springs. Persistent

droughts in recent weeks have led to a

significant shift in this distribution.

“At the moment we get around onefourth

of the drinking water from the

springs — the remainder we can cover

with the deep wells,” said Axel Grether,

water specialist at Endress+Hauser.

While water levels in the springs are

fluctuating heavily, to date the deep

wells have remained quite stable

despite the ongoing drought. The level

dropped only 50cm between January

and the end of July.

“This gives us an edge over other

communities whose only source of

water is springs,” said Dietmar Thurn,

head of the building authority. The

municipality with a population of

10,000 also modernised the water

network and installed pump lines and

numerous measurement instruments

WATER DOWN WITH

smart water technology

With growing concern surrounding our climate and

water resources, smart technologies can prove to be

an efficient solution for water conservation.

By Mei Ling Quek, vice-president of Renew Group

HANS Premium

Water RO System

As we look into our future, it is hard to forget

that the climate crisis is a harsh reality that

we will have to face. With the burning of fossil

fuels causing rising temperatures, we also see

its reeling impacts, like the recent floodings

in Bangladesh, severe droughts in Italy, and

the high temperatures of 36.7°C in Singapore.

Suffice to say, a direct consequence of global

warming is the increase in longer periods of

extreme rain and droughts, affecting a basic

necessity for living: water.

In 2018, the Intergovernmental Panel on

Climate Change (IPCC) report highlighted a

pressing need to limit warming to 1.5°C above

pre-industrial levels, which in turn lowers the

barriers to freshwater access. To achieve this,

it is crucial to halve carbon emissions by 2030

and hit net-zero carbon emissions by 2050.

It might seem like a tall order, but a growing

number of governmental, non-governmental

bodies and countries have already started

banding together to establish sustainable

trade policies in light of pivoting to a green

economy, with international treaties such as

the Paris Agreement, which has been ratified

by 193 countries. Recently, The World Trade

Organisation (WTO) has also called for an

urgent greening of trade in light of the dire

situation.

WATER, ENERGY,

AND DECARBONISATION

As global policies are rolled out in favour of

mitigating climate change, businesses need

to take immediate actions to eliminate the

pressing impacts of the water shortages

across industrial sectors. While carbon

emissions are caused by burning fossil fuels,

water conservation also plays a huge role in

fighting climate change and maintaining water

security for industries worldwide.

One might ask: “How so?”; water and energy

are linked in a cycle where energy production

is needed for water and vice versa. Although

energy is a resource that powers our world, it

also necessitates the burning of fossil fuels for

energy. In both industrial and domestic water

management, energy is needed to filter, heat

and pump water into buildings and homes.

Thus, some of the largest consumption of

energy come from homes and buildings,

which account for over 38% of global carbon

emissions, making water conservation in

buildings more critical than ever. Lighting,

heating, and cooling are building operations

that require energy and water. Water

wastage is also of growing concern, as

wastewater tends to be disposed instead

of being reused or recycled. Furthermore,

there is a lack of accountability for industrial

wastewater discharge due to poor monitoring

in the industry. When water is seemingly an

abundant resource covering 71% of the Earth,

it can be hard to realise that water shortage is

a threat.

WATER AS A SCARCE RESOURCE

Today, only around 1% of the world’s water

supply is available for drinking, and almost

least one month each year; while a third

water scarcity becoming an issue as

our drinking water supply diminishes,

the United Nations has pledged

Sustainable Development Goals (SDG)

to mitigate the crisis. SDG Goal 6 aims

to ensure availability and sustainable

water management and sanitation for

all, with businesses encouraged to

improve their water efficiency to target

the water crisis.

Furthermore, the world relies on water

for energy and food production. It

is forecasted that the global water

demand may rise by 30% within the

next 30 years. With an expected

population of 9.8 billion inhabitants

on Earth by 2050, this comes as no

surprise. Both domestic and industrial

sectors will have to increase their

water use to accomodate the growing

population. With global economic

growth, development and GDP

swelling, industries that rely on water

will have to increase their water use to

keep up with demands.

Even in countries like Singapore where

drinking water is easily available, the

increasing water demand is still a

growing concern. Singapore relies on

external sources of water supply due

to its lack of natural resources and

small size. This poses a constraint,

especially with local water demand

expected to double by 2060. As water

conservation becomes a top priority in

industries worldwide, local businesses

should look towards achieving water

sustainability through the advanced

technologies of today.

alone aims to green 80% of buildings

by 2030, and is more than halfway on

track with 49% of buildings already

greened.

Greening buildings for water

sustainability can be done by retrofitting

buildings with IoT and AI technologies.

These smart technologies can help

regulate energy and water efficiency

and reduce usage without affecting

user experience. For example, an

integrated smart shower system

that adjusts the water flow based on

needs, tracks water consumption, and

analyses usage patterns via digital

platforms, can be installed in buildings.

This smart technology solution can

BUSINESSES LEADING WATER

CONSERVATION

While governments hold sway in a city’s

structure and policies, environmental

sustainability and water conservation

should be a collaborative effort between

government bodies, businesses and

individuals. Businesses have more power

than they think — mobilising their resources

and working together with governments

can reduce the impact on the environment.

In fact, around half of carbon emissions

are contributed by conglomerates carrying

out activities in agriculture, forestry, and

transport in urban cities.

This extends to the public — businesses

can affect public consciousness and

opinion on particular topics. By promoting

sustainable lifestyles, businesses change

social norms and behaviours in the long run.

For example, they can increase awareness

in developing countries on the sustainable

NEXT IN THE PIPELINE

Water is an indispensable resource. However,

while oil and gas have sustainable alternatives

such as solar or wind, water has none.

Education on water conservation is important

for us to understand the extent of water used

in industries. For example, when a consumer

buys a one-litre bottle of water, they may not

realise that it takes more than five litres of

water to produce that one bottle. As we use

more water, the cost to develop and clean

water also goes up. While water becomes

a difficult resource to obtain, surging prices

are transferred to developing countries that

may not be able to afford the luxuries of

water or even countries that rely on others for

water. They have to think forward about the

future of water access as demand escalates.

Alternative ways through new technologies

like the HANS Premium Water RO System can

future-proof water access for consumers and

industries.

DESIGN WITH WATER 2.0:

Collaborative tools for

place-based outcomes

As the water industry faces a series of new challenges in this decade,

Arup has revealed its refreshed Design With Water framework,

supporting more resilient and holistic outcomes for communities.

By Paul Simkins, associate, Arup

It has been almost a decade since Arup

developed its original Design With Water

approach: a vision for outcomes-led design that

has shaped the company’s work,

strategy, and projects around the world.

Arup was founded on the principles of

integrated design: crossing silos, and balancing

science, engineering and creativity with social

and environmental value to create better

outcomes. Current global challenges continue

to highlight the need for holistic, regenerative

approaches to design. Of these challenges,

water is more critical than ever. However,

no system can be considered in isolation.

Addressing water requires a whole-systems

approach, rethinking the way it is designed and

how it works together.

Arup’s Design With Water model is based on

the principle that restoring, protecting and

enhancing the integrated water cycle can

become a catalyst and enabler for increasing

the resilience, health and wellbeing of our

human and natural systems.

Recently, Arup has been updating the model

to reflect changes in design practice, delivery

context and new ways of working. Based on

ongoing learning and feedback, the wholesystems

framework has been refreshed and

extended, and a new toolkit will be added for

creative and collaborative design.

RETHINKING DESIGN

Design With Water (DWW) 2.0 continues

to support an outcomes-led approach. It

emphasises the consideration of place-based

needs and priorities, partnership working and

shared value, provoking designers to think

differently and explore the opportunities that

can be unlocked by understanding the role of

water in developing infrastructure solutions.

The framework includes four cross-cutting

principles that underpin Arup’s approach to

design:

“Integrated” emphasises a whole-systems

approach, working across multiple sectors,

perspectives and scales, bridging technical

and non-technical disciplines. It goes beyond

combining multi-disciplinary inputs towards

collaborative design.

“Smart” draws on technological, social and

cultural innovation, from the latest in digital and

data-driven design, to ecological knowledge

and nature-based design, user experience,

historical and cultural perspectives, scenario

planning and foresight.

36 WATER & WASTEWATER ASIA | SEPTEMBER/OCTOBER 2022


FOCUS

“Resilient” focuses on designing for people,

places, institutions and systems to survive,

adapt and thrive in response to shocks and

stresses. Over the past ten years, Arup has

developed global tools to support resilient

design and adaptive planning.

“Regenerative” centres on design that rethinks,

restores and enhances existing natural and

human systems from community to catchment

scale. For DWW, this means water cycle

interventions that go beyond sustaining

other systems to creating net gain across all

outcome areas.

SHARED OUTCOMES, SHARED VALUE

Delivering shared outcomes depends on

establishing shared values. This can be

challenging, as systems are interdependent

but often disconnected. There will be different

perspectives, interpretations, capacities and

priorities. There will be different definitions of

value and different ways of valuing outcomes.

Building shared understanding around vision

and outcomes takes time, but the process is

often valuable, enhancing capacity amongst

design teams, partners and communities.

Water can be a catalyst and enabler,

supporting other sectors who are grappling

with their own specific challenges.

evaluating enables teams to engage with

complexity in a way that is accessible,

interactive and fun. It creates a space to

explore different perspectives, establish

shared values and priorities for planning,

design, investment and evaluation.

RETHINKING ASSETS

How assets are defined impacts what one

values, how one collectively invests, what

one owns, manages and maintains, and the

returns one expects. Yet the term “asset”

means different things to different people,

and varies across sectors and cultures.

Rethinking assets is key to unlocking new

ways of designing and delivering multi-sector

outcomes.

To address this challenge, DWW considers

water-cycle assets as a series of linked placebased

systems that can be applied at a range

of scales, from households and communities

to cities and catchments. Traditionally, these

layers have been designed and managed by

separate sectors, agencies and disciplines,

but to deliver the best outcomes, they need to

be considered as an integrated system.

The model builds from fundamental

catchment characteristics such as water

resources, land use and topography, through

strategic water and sanitation networks,

to nature-based interventions and water

sensitive urban design. Finally, investment

in non-physical assets such as community

organisations, jobs, culture and user

experience are emphasised as fundamental

to effective system design and operation.

The simple framework can help water

professionals to think beyond conventional

water infrastructure towards wider urban,

natural and social systems. It can help other

stakeholders and communities to explore

their interactions with water. For example, one

might emphasise the value of nature-based

solutions or highlighting critical infrastructure

such as water supply networks that in certain

contexts may be considered out-of-sight,

out-of-mind.

This framework can be applied conceptually

or by using place-specific data and insight

to inform design. Using a range of prompts

and supporting materials, integrated concept

ideas and options can be co-designed and

directly linked to outcomes.

NEW STEWARDSHIP MODELS

Whilst these different layers are interdependent,

they have historically been

considered by separate agencies with ring-

It can be tempting to reduce complexity

by retreating into silos or creating isolated

policies and projects, but promoting an

outcomes-led design depends on integration

across boundaries, understanding the whole

water cycle and seeing it from different points

of view.

To facilitate this process, DWW 2.0 develops

the outcomes framework expanding each

dimension with further detail and supporting

materials. This is intended as a flexible

starting point and way in, accommodating

different user needs, project context and

resources.

Supporting a framework with methods for

customising, discussing, prioritising and

fenced roles and budgets, often with different

objectives and timescales.

This is changing, but a few typical examples

demonstrate the legacy of a fragmented

approach to valuation, ownership and

maintenance of assets that is still slowing the

implementation of resilient and regenerative

solutions.

Green infrastructure delivers value across

multiple sectors, but it can be difficult to align

beneficiaries and investors to ensure longterm

stewardship, often stalling design and

delivery.

Persuading private developers without a

long-term interest to invest in water innovation,

especially where assets cannot be adopted by

water companies or local authorities, can be a

challenge.

A third-sector organisation might be critical

to community flood resilience, yet it can be

hard for them to secure long-term funding;

however, Arup plans to invest in maintenance

of traditional assets like buildings, pumps or

flood defences.

There is a need to rethink the roles of different

stakeholders and the wider delivery context

to unlock new whole-life stewardship models.

This includes exploring the role of the water

sector as an anchor institution alongside

the public, private and civil society

organisations.

These challenges are not so much technical

as strategic — requiring engagement with

wider system enablers such as governance,

regulation, policy, funding and finance.

The role of designers is becoming more

complex.

COLLABORATIVE TOOLS

Designing in new ways requires new

processes and tools, particularly around

engagement and collaboration. Arup has

been developing a toolkit to help teams

navigate complex delivery environments to

reach creative, deliverable solutions.

Eight complementary components have

emerged through research and prototyping

in response to project needs. They form

the building blocks of outcomes-led

design. Arup has drawn upon learning from

multi-sector work across city resilience,

regenerative design, partnership funding,

health and wellbeing, engagement and

user-experience design.

The DWW 2.0 toolkit can be used to support

all stages of a project, from visioning and

project inception to the implementation and

evaluation stages. Outcomes-led design is

not a strictly linear process. It requires

iteration and feedback between different

activities and there can be different entry

points. Tools can be selected individually or

joined in different combinations. Each can be

adapted and will continue to evolve through

use. This flexibility allows designers and

facilitators to tailor activities and outputs to

specific user needs, project objectives and

resources.

DESIGN WITH…

It has been almost 10 years since the first

edition of Design with Water; and 50 years

since Ian McHarg’s Design with Nature was

published alongside a range of influential

texts that has shaped ecological design and

are still relevant today.

As Arup reconsiders the role of design in light

of new challenges, the word “with” seems

more important than ever.

Designing with water, nature, people,

place, uncertainty, time requires embracing

complexity, pushing boundaries and

absorbing more into current practices with

a focus on shared outcomes; it means

extending one’s skills and broadening

collaboration with others.

AMMONIUM-

BASED AERATION

control in wastewater

control has greater complexity but offers the

potential to achieve the best effluent quality

at the lowest energy cost. Additional detail

on feedback and feed forward control can be

found elsewhere*.

DIRECT FEEDBACK CONTROL

The simplest method is direct control

of aeration based on feedback from the

ammonium measurement. In this approach,

aeration rate is controlled directly based on

the online ammonium measurement. The

Wyoming Valley Sanitary Authority (WVSA)

in Pennsylvania uses online ammonium

ISE measurement to ensure nitrification is

complete and to maximise nitrogen removal.

Blowers cycle on and off to maintain the

ammonium-nitrogen concentration between

set points of 0.7 and 1mg/L in each of four

treatment trains. Blowers are “off” 25% of

the time with this strategy, creating anoxic

conditions for denitrification and saving

about $20,000 per month in energy costs*.

The substantial additional removal of

nitrogen achieved is below the permitted

effluent load and generates nutrient credits

that WVSA sells to other sources in the

Chesapeake Bay watershed.

The introduction of simple, reliable, and

affordable in situ sensors based on ion

selective electrode (ISE) technology provides

the opportunity for more advanced activated

sludge control strategies, such as aeration

control using ammonium as a response

variable in addition to, or in place of dissolved

oxygen (DO). Ammonium-based aeration

control has been implemented at many water

resource recovery facilities (WRRF).

While the automation of aeration based

on ammonium measurement would be

beneficial for many facilities, the applicable

control strategy for a particular facility

depends on specific factors, including system

configuration, performance requirements

(discharge limitations), and wastewater

characteristics. The following article identifies

several control strategies. The approaches

described offer the potential to enhance

treatment performance, reduce operating

costs and, in some cases, even generate

revenue from nutrient credits.

Utilities have implemented ammonium-based

aeration control based on feedback and feed

forward strategies. Feedback control is based

on measurement of the response whereas

feed forward control is based on measurement

of the disturbance. Feedback control is much

more common in the water industry but can

have limitations in a highly dynamic system

like wastewater treatment. Feed forward

The success of the WVSA application

using direct control can be attributed to

the completely-mixed (CM) configuration

of the treatment system, the built-in mixing

capability of the Schreiber counter-current

system, and the simple control law (onoff).

This strategy may not be optimal for

many applications, however. The drawback

to direct control using ammonium is that

the DO concentration is not controlled.

Failing to also optimise DO causes

inefficiency because DO varies more

rapidly than ammonia and, therefore, can

rise or fall to undesirable levels. The rate

of nitrification increases proportionally with

DO concentration up to about 1.5-2mg

DO/L. However, above a DO of 2mg/L only

a marginal increase in the nitrification rate is

achieved (Fig 1). Furthermore, a higher than

needed DO is detrimental to denitrification.

WATER & WASTEWATER ASIA | SEPTEMBER/OCTOBER 2022 39


FOCUS

Therefore, if DO is not optimised, nitrification

capacity is limited or denitrification capacity

is limited and energy is wasted.

CASCADE FEEDBACK CONTROL

Nitrification and DO concentration are

both optimised in a cascade control

arrangement. The ammonium controller

shown in Fig 2 compares the measured

ammonium with the ammonium set point

and calculates the DO set point which is

forwarded to the DO controller. The DO

controller compares the measured DO

concentration with the calculated set point

and calculates the required air flow which

is forwarded to the air flow controller. This

requires tuning four control loops (pressure

loop not shown) increasing the complexity

of the control system. Alternatively, the

DO controller may be set on top of the

ammonium controller to limit the DO

concentration to a maximum value.

One potential problem with this

configuration is that the two controllers

fight over authority because the DO

concentration changes faster than the

ammonium concentration.

Proper location of the ammonium

sensor(s) presents an additional level of

complexity for plug flow (PF) reactors.

In a CM configuration, sensor location is

somewhat irrelevant because concentration

is the same throughout the reactor. In a

PF configuration, concentration varies

along the length of the reactor with

higher concentrations upstream and

lower concentrations downstream. One

philosophy is feedback control based on

measurement of effluent ammonium. This

provides a direct indication of performance

but a delayed control signal.

By the time an effluent ammonium sensor

detects a peak loading, it may be too late for

a correction, especially for highly dynamic

influent loadings and reactors with long

retention times such as in single-stage

nitrification. The control system depicted in

Fig 3 is based on a control signal from a DO

sensor located at the effluent end of the

aeration tank. Upstream ammonium (red

line) spikes several hours before air flow

(blue line) responds allowing DO to fall to

undesirably low concentrations (green line).

As a result, ammonium breaks through the

effluent (purple line).

Locating the ammonium sensor upstream

from the effluent offers a few advantages.

First, the lag time for the control signal is

reduced. Second, locating the ammonium

sensor closer to the effluent increases the

reliability of meeting performance goals.

Third, maintenance of an ammonium

ISE is easier at concentrations between

1-10mg/L. As concentration decreases,

“noise” becomes a higher proportion of the

signal, creating a challenging environment

for performing accurate calibrations (matrix

adjustment), increasing operator frustration

and reducing measurement reliability.

The chart in Fig 4 is the result of a strategy

to control the DO concentration in the

main oxic zone based on feedback from

ammonium sensors at the midpoint and end

of the zone. The drivers for control were

effluent quality and energy conservation.

The goal was to conserve alkalinity, and

more reliably meet effluent pH limits,

by limiting nitrification only to the extent

required to meet the ammonium limit which

varied monthly.

Energy conservation would be achieved by

limiting the DO set point based, in part, on

the ammonium measurement as follows:

achieved the lowest unit airflow demand,

11% lower than with DO feedback control,

achieving the main objective which was to

reduce energy usage*.

Fig 3: Feedback control

of aeration based on

effluent measurement*

The stated advantage of feed forward

control is that the system reacts faster to a

disturbance, eliminating short term effluent

peaks and allowing a smoother control. The

reality is that predictions are only as good

as the model on which they are based and

models are not perfect. Therefore, feedback

from an effluent ammonium sensor is also

recommended to correct for errors in the

model. Some have stated that the benefit of

feed forward aeration control does not, in

most cases, provide substantial benefit over

feedback control and thus the additional cost

and complexity is not justified*. However, in

cases where peak loadings are large and/

or rapid and where effluent limits are very

stringent, feed forward control may offer a

practical solution.

control with upstream

ammonium sensors*

Regardless, monitoring wastewater

ammonium, and COD for that matter, online

will provide very useful in- formation on

wastewater dynamics which can improve

treatment whether or not the information is

directly input to a control loop.

CAPTURING WATER DATA

for a true smart network

Drinking water systems in the United States currently lose at least six

billion gallons of water every day, according to the American Society of

Civil Engineers’ 2021 Drinking Water infrastructure report. Ovarro’s associate

product line manager for leakage, Chris Moore, shares insights into

how to become smarter in leakage detection.

Smart leak detection

solutions can help

utilities with cost

effectiveness and

sustainability

There is a water main break in the

US every two minutes, according to

the 2021 figures from the American

Society of Civil Engineers. Meanwhile,

the 2.2 million miles of water mains

across the USA are ageing and

underfunded. Treating water to

drinking water quality is expensive —

utilities do not want to lose 25-30% of

drinking water through leaking pipes.

Besides huge environmental impacts

on stretched water resources, losing

30% of treated water is bad news

from a financial and reputational

standpoint.

At the same time, the urgent

need for utilities to tackle the

effects of climate change, growing

water stress and increasing

populations, is not going away.

The good news is, investment

programmes in the US are

expanding and water utilities are

building their resilience, while also

deploying more innovative water

technologies for smarter networks.

It is a viable time to ramp up leak

detection in a cost effective and

sustainable way and accelerate

the adoption of new technology.

LEAK DETECTION IS A SKILL

The expertise to find leaks on

huge water distribution networks

is accrued over many years.

44 WATER & WASTEWATER ASIA | SEPTEMBER/OCTOBER 2022


FOCUS

There are huge gains to be made

by embracing joint-working. In

leakage, the vast local network

knowledge embedded within

utilities and municipalities,

combined with the research and

development capabilities of the

supply chain, can lead to significant

technological advancements.

Historically, leak detection efforts

would focus on a specific area.

The common approach would be

to let leakage creep up over time in

that area and then send teams to

reduce the overall leakage.

Now, the Internet of Things (IoT)

is reshaping network monitoring

allowing utilities to move to fixed

water networks of permanent

monitoring devices and loggers,

capturing data which is fed

back to a central system via

communications technology.

This is increasing real-time and

predictive capabilities — leak

detection systems can be set up to

permanently monitor the network in

real-time. What we effectively have

is a permanent network alarming

device, capable of detecting leaks

early.

DATA LOGGERS ARE

THE FIRST STEP IN LEAK

DETECTION

Having data loggers on the

network provides a top-level

overview; it allows companies

to accurately and reliably record

parameters for pressure, flow and

level across the water network.

Establishing a baseline helps to

plan an effective leak detection

campaign.

The data can provide insight

into areas that you might want

to focus more on and highlights

trends occurring on your network,

that you may not have known were

happening. This extra set of eyes

allows you to be more targeted in

your strategies.

If a standard leak detection

system making one recording per

night flagged up a new location

of continuous sound, a network

manager would have to know that

the noise was not just activity from

a consumer. Thus, if someone were

to draw from the network for their

heating system or their washing

machine, a leak detection system

would say there is noise at this

position.

The water utility may then wait, then

listen again for the next few nights to

verify the position of the sound. The

chances of that being consumption

in the same location is minimal. It is

now worth sending out a team, but

that leak has been running for three

days before someone has gone to

investigate.

By tying the data logger and the

leak detection equipment together,

we can then run a much smarter

system. The logger looks at what

known as the nightline — the

minimum night flow.

If that increases and is consistent,

it is very likely to be a leak. When

that happens, that logger can send a

message to cloud network software,

which will then verify that there is

certainly flow increase in the area.

Therefore, rather than the leak

detection equipment waking up

once at maybe 2am and making a

10-second recording, we can tell

it there is something to find. The

equipment then knows to record

three times, say at 2am, 3am and

4am. By the time someone from

the utility arrives at their office,

switches on their computer and

sees the data, the system has

automatically reduced those three

days of monitoring down to the

next morning.

REDUCING LEAKS CUTS

CARBON EMISSIONS

Water and wastewater operations

typically contribute 30-40% to

a municipality’s total energy use

and the global sector is currently

estimated to contribute up to 5%

of greenhouse gas emissions. The

link between leakage and carbon

should not be underestimated.

The more water we save through

leakage reduction, the more

energy we stop wasting, through

the pumping of treated water that

ends up being lost through leaky

pipes. If a utility can reduce the

amount of water being treated

and put into supply, it will reduce

the amount of energy being

consumed, leading to a drop in

operational carbon emissions — a

win-win situation.

Preventing leaks is a

big step forward for

energy conservation

SOLUTIONS

pack a punch

“Clean water is the world’s first and

foremost medicine.” - Slovakian proverb

By Agatha Wong

an integrated turn-key EPC and O&M

technology solutions provider. Its core

services include a Compact Water

Purification System (CWPS) — a

suitcase-sized portable water treatment

unit which can be deployed for

emergency response and use in remote

locations. Another compact solution

is the forward osmosis suitcase,

which Liquinex developed alongside

Aquaporin, making use of the latter’s

biomimetic membrane that draws pure

water out of wastewater. Besides that,

the company also offers industrial

water treatment, where its system is

designed to be semi or fully automatic,

minimising human intervention during

operation, alongside additional options

such as remote monitoring and control

systems.

OFF THE BEATEN TRACK

Liquinex’s product portfolio evolved

out of a response towards regional

and global water needs. With water

infrastructure in Asia-Pacific, for

example, still requiring further support

and improvement, water companies

must tailor their solutions to not only

meet urban demand but also rural and

community needs.

Bashir Ahmad, who

worked previously for

Singapore’s Public

Utilities Board, is

co-founder and CEO

of Liquinex

The water challenges facing Singapore

are unique and require an innovative

lens. From NEWater to rainwater

harvesting, the island nation is home

to some of the most advanced water

technologies and solutions.

For Bashir Ahmad, who worked

previously as an engineer overseeing

the construction work for a sewage

treatment plant under the thensewerage

department at the

Ministry for the Environment, and a

mechanical engineer for the Public

Utilities Board (PUB), both located in

Singapore, the local perspective has

provided much insight to business

operations at Liquinex, where he

serves as co-founder and CEO.

“Singapore’s challenging water

landscape and its innovative approach

towards solving water scarcity inspired

my desire to help solve water scarcity

problems in the region. Liquinex’s

award-winning compact water

purification system was developed out

of the need to provide clean water in

times of disaster as well as for remote

rural communities,” shared Bashir.

The company was founded in 2015 as

a specialist in water and wastewater

treatment technologies, and is today

This was a sentiment echoed by Bashir,

who said: “Water companies should

be mindful that their water treatment

system should fit the purpose and

needs of the communities that they

are serving, be it aid agencies, rural

communities or local water authorities.

Since 2015, Liquinex has spearheaded

humanitarian water projects to rural

communities, municipalities and

industrial companies, supporting their

hydration, hygiene and sanitation

needs, as well as regulatory

compliance during the COVID-19

pandemic. In these projects, the

aforementioned Compact Water

Purification System was an easy-

to-transport system that delivered potable

water to these remote locations. Powered

by 12V car batteries or solar panels, it can

provide 3,000 litres of bottled-water quality

drinking water per day to over 600 people (as

calculated on a fully-charged car battery on a

six-hour power supply).

These projects have proved invaluable to

the company as they understood the varying

needs of different communities: “A key lesson

that we have learnt is that no one solution

fits all. Each community has its own unique

circumstances and some customisation

is always needed. In order to deliver clean

water efficiently, we have taken the approach

to minimise the size of our system without

compromising on throughput and efficacy.”

Moving beyond rural areas, the company

is also conscious of the evolving needs

of an urban population. As Asia-Pacific

becomes one of the fastest growing regions

in the world, steps to counter pollution and

deliver clean water to homes become more

important.

“Looking ahead, water companies should

address emerging threats from micropollutants

such as those originating from

pharmaceuticals, personal care

products including micro-plastics

that is becoming more prevalent

due to rapid urbanisation and climate

change. To this end, we are working

with strategic technology partners

to develop novel systems using new

technologies such as carbon nanotubes

and deep UV disinfection,” said Bashir.

ON THE WORLD STAGE

For their work, Liquinex has been

recognised on the international stage. The

company received the Mohammed bin Rashid

Al Maktoum global water award in Dubai in

2020, as recognition for their solutions to

secure clean water for poor communities. In

April of the same year, the company was also

awarded a gold medal in the international

invent show AsianInvent Singapore 2020 in

Singapore.

Most recently, the company has also signed a

deal with LightLab. This collaboration will see

the integration of LightLab’s broadband Deep

UV disinfection technology known as PuriFize,

with Liquinex’s WaterWall, for residential use.

Through this, contaminated water can be

turned into safe tap water. The first to receive

this technology will be Jakarta, Indonesia.

Bashir said: “We are humbled by the awards

and accolades and are grateful to UAE Water

Aid, AsianInvent Singapore, Imagine H2O-

Asia, Intellectual Property Intermediary and

the entire Liquinex team including co-founder

Mr Riaz Deen, for their recognition and

support. We are very excited to work with

strategic partners in solving industrial and

municipal water challenges and also on our

next generation suitcase-sized Compact

Water Purification System and Liquinex’s

BIO-INSPIRED

AND SELECTED

BY EXPERTS:

The new “Ridge-M”

membrane technology

from Berghof

Berghof Membranes’ Ridge-M technology gains

recognition at the German Innovation Award 2022.

The German Innovation Awards honours

innovative achievements that break new

ground through their added value; projects

that improve lives and contribute to a better

future.

Berghof Membranes aims to enable a

more sustainable industry with innovative

solutions, and in doing so conserve the

world’s precious resources. With the new

Ridge-M technology, Berghof Membranes

can better help their customers to achieve

their goals.

This is because the company’s developers

have been bio-inspired by a natural principle:

With everything in nature constantly evolving,

the company aims to use its available energy

as efficiently as possible.

This principle from nature is the foundation

of all developments at Berghof Membranes.

The latest idea serves as an example of a

new approach to the design of membranes

for industrial water treatment that benefits

customers in several ways.

The inspiration for this technology came

from shark’s skin. After months of testing

in the laboratory and in practice, Berghof

Membranes presents its membrane

technology that harnesses this principle from

nature: Ridge-M.

Multiple sharkskin-inspired ridges in the

length of the inside of the membrane increase

the surface turbulence due to uneven shear

stress distribution. The technology creates

a continuous mixing of solids in the feed

water, delaying the forming of a cake layer

on the membrane surface. Possible fouling

between the ridges is removed easily due to

the combination of turbulence and uneven

shear stress.

The new Ridge-M technology, according

to the first field tests, can boost average

performance up to 50%, depending on the

application and the operating conditions.

It also lowers the average consumption of

energy up to 33% compared to the standard

membranes from Berghof. Chemical

consumption is also reduced.

BERGHOF CONVINCES EXPERTS ONCE

AGAIN

The initiator of the German Innovation Award

is the German Design Council (Rat für

Formgebung), founded by the German

Parliament in 1953. It is considered by experts

as one of the world’s leading centres of

expertise in communication and knowledge

transfer within design, branding and innovation.

It has also been the sponsor of one of the most

recognised design competitions in the world,

the German Design Award, for many years.

The German Design Council has also honoured

the Berghof Group for the fourth time in 2017

and 2019, with the awarding of the German

Brand Award. With it, the German Design

Council aims to position the brand as a

deciding factor for companies in the national

and international competitive environment.

In 2021, the testing technology division of the

subsidiary Berghof Automation was among

the winners of the German Innovation Award

in the machines and engineering category

with its Smart Component Tester (SCoT), also

in the excellence in business-to-business

competition class.

This year, a total of almost 650 innovations

were submitted to the critical judgment of the

German Innovation Award jury, which is made

up of independent, interdisciplinary experts

from industry, science, institutions and

finance. The entries are evaluated based on

the criteria: level of innovation, user benefits

and efficiency.

REAL-TIME CHLORINE

MEASUREMENTS

in drinking water

LACROIX’s latest sensors can facilitate strict monitoring

of chlorine levels in drinking water, putting utilities at a

peace of mind.

Controlling the level of chlorine in water

networks is crucial to guaranteeing the quality

of drinking water. Monitoring active chlorine

levels in drinking water distribution networks

is becoming more important across the world,

while regulations in some countries have

made it imperative that water suppliers can

constantly monitor these levels.

To solve the challenge of active chlorine

level monitoring, LACROIX has developed

the ChlorIN sensor. When connected to a

SOFREL data logger, it collects chlorine

levels at regular intervals. This continuous

monitoring means that an alert can be sent to

the operators and the centralisation software

should the chlorine level exceed or fall below

thresholds set in the software.

This brings numerous savings to the operator,

from less travel time and working on-site, to

supplying more extensive data. The sensor

can be installed anywhere on the water

network, and it can be used to monitor critical,

strategic, or interconnection points, as well

as at the end of the network. The internal

battery has a service life of up to 10 years.

A version with an external power supply is

also available, allowing the data logger to

be powered for even longer via an external

source, be it a battery, mains power or a solar

panel.

The sensor can be installed to existing

water pipes, without interrupting the flow of

water. The attached sampling valve allows

for immediate sensor calibration. Data is

transmitted via 2G/4G networks, via an

integrated high-capacity antenna. The

ChlorIN sensor is also available with an

additional CPR pressure sensor for service

quality measurements.

SOFREL DL4W OPENSENSOR DATA

LOGGERS FOR MORE SENSOR

OPTIONS

The new range of SOFREL DL4W data

loggers allows the connection of up to

eight sensors, thanks to an open Modbus

connection.

The open Modbus model allows the data

loggers to meet the monitoring needs

of both drinking water and wastewater

networks. The high power model is preequipped

with a connector allowing the

connection of an ultrasonic level probe

and is usually used for self-monitoring

and permanent diagnostic needs. The

RS-485 serial input is compatible with all

Modbus RTU equipment.

Two additional DIs make it possible to

also measure pulses, for example, to

signal the opening of the manhole cover,

or to monitor an overflow sensor or rain

gauge.

Jesper Bentzen, sales director of Danfoss,

shared: “Owners and operators of large

SWRO plants are increasingly turning to

these smart solutions to improve reliability

and reduce operating expenses. Because

active ERDs use motors controlled by

variable frequency drives, each ERD can

now be integrated in automation systems to

further optimise energy savings both onsite

and remotely. Additionally, electrical data

from the ERD motors can now be monitored

and analysed to detect minor anomalies

before they turn into major problems. This

enables better planned stops, more efficient

maintenance, and better OPEX overall.”

To accommodate large flow rates and

facilitate easy installation and optimal

manifold structure, several MPE 70 ERDs can

be mounted in parallel on a rail with a unique

adjustable bracket.

Until now, isobaric ERDs for large and

medium SWRO plants have been passive:

their rotating pressure exchangers have

been driven only by pressurised water flow.

While passive ERDs exchange pressure

efficiently, rotor spin controlled only by

water flow presents operators with several

problems. One is overspin, which occurs

when passive ERDs operate above their

maximum flow rates and can cause rotors

to break apart. Another is salinity increases

due to mixing: to prevent overspin,

operators of passive ERDs must avoid

overflushing, which would otherwise reduce

the salinity increase due to mixing. The

resultant higher feed flow salinity lifts the

plant’s energy consumption and reduces

membrane life.

“The MPE 70’s motor controls rotor rotation

to eliminate any risk of overspin,” explained

Michael Bjorn, head of Danfoss’s high

pressure pumps division. “For the first

time, ERDs in medium and large plants

can now operate at their maximum flow

rates with complete safety and reduce

salinity increases due to mixing even when

overflushing. Motorisation not only reduces

the need for ERD redundancy, which in

large plants can add up, but also improves

larger SWRO plants’ energy efficiency.

Furthermore, it has significant benefits

for plant reliability and maintenance. The

low-voltage motor can always initiate rotor

spin, so the days of biofouling stopping rotor

rotation are over. And if operators temporarily

need to shut down one train for maintenance,

BUILDING ON A TRACK RECORD

Danfoss has served the desalination industry

with high-pressure pump and ERD solutions

for decades. The MPE 70 now puts an

energy recovery solution proven in small

and medium-sized plants at the service of

owners and operators of the world’s biggest

desalination plants.

“As a thirsty world deals with climate

change and CO2 emissions, the focus

on reliable energy efficiency for SWRO

has never been greater,” said Bjorn. “We

believe the advantages of active ERDs are

a gamechanger for the large-scale plants

that already now provide many communities

worldwide with their drinking water, and will

be even more important in the future.”

ASIAWATER 2022 will bring together over 17,000

trade attendees and visiting industry professionals

from 65 countries, with over 1000 exhibiting

companies and brands

ASIAWATER 2022 will be accompanied by

free-to-attend conferences and seminars

featuring leading industry experts addressing

current issues and opportunities, latest

technologies and challenges within the water

and wastewater industry.

ASIAWATER MAKES

sustainable return

Digital features and insightful forums set the

tone of this year’s event

The 12th edition of ASIAWATER Expo &

Forum will return on 7–9 Dec 2022 at Kuala

Lumpur Convention Centre, Malaysia. The

event will be an international water and

wastewater event for Asia, showcasing the

latest in high-tech, low-cost products and

solutions from around the globe in the fields

of water resources management, sewerage,

industrial wastewater, purification, irrigation,

and many more.

ASIAWATER will provide a sea of trade

opportunities for players from every sector

in the water industry, connecting over

17,000 trade attendees and visiting industry

professionals from 65 countries, with over

1000 exhibiting companies and brands, from

all segments of the water and wastewater

industry.

The central theme for ASIAWATER 2022

will be “Embracing ESG Towards Water

Sustainability”, and the show will be touching

on the importance of implementing ESG by

the region’s water and wastewater services

industry in working towards providing us a

more sustainable, reliable and affordable

water services. Specifically, ASIAWATER

2022 shall look at the water industry not only

in South East Asia as a primary audience,

but also regionally in Asia-Pacific.

Digital features have also been added to

meet these sustainable goals. One such

feature is the reducing of the event’s carbon

footprint by reducing or eliminating the

printing of our event directory and replacing

them with a digital interactive version.

With this digital directory, WATERFEEDS,

trade visitors can easily access the event’s

agenda, exhibitors’ booth and their location,

as well as have the ability to connect with

exhibitors online. Moreover, trade visitors

can also download the digital version of the

event floor map as well as the show directory

booklet in digital format, providing all they

need at their fingertips.

Another new concept that will be

implemented for the first time at ASIAWATER

would be hybrid booths for exhibitors who

cannot participate in-person at the event.
