FROM THE EDITOR
IS THE GLASS HALF
EMPTY OR HALF FULL?
The answer: the glass is always full. It is filled
half with water, and half with air. Similarly, as
individual players in the water industry might
not be sufficient to solving the most immediate
issues of this day and age, organisations
from the private, public, and academia
sector should come together to create a
comprehensive plan for the rocky years ahead.
Where one falls short in certain aspects,
others must step forward to fill in possible
shortcoming.
It goes without saying that 2022 has seen
significant highs and lows for the water
industry. From recording-breaking heatwaves
and extended droughts, to the emergence
of a new normal in a post-pandemic realm,
companies, utilities and governments around
the world have dipped their toes into the
uncharted waters of dealing with a rapidly
changing world. While we continue to navigate
this unpredictable realm, it has become
evident that working together towards a
common goal is the only way forward.
Take Veolia Water Technologies, for example:
in collaboration with Mölnlycke, a medical
products provider, the company has
formulated sustainable wastewater treatment
solutions for their recently inaugurated plant
in Kulim, Malaysia. By taking stock of the
demands in medical glove manufacturing
and keeping abreast of sustainable goals in
the country, Veolia was able to integrate a
treatment designed to further the company’s
green targets.
Similarly, Grundfos recently signed a
memorandum of understanding with
Singapore Polytechnic to develop water and
energy efficient solutions across various
industries. The former will utilise its experience
in smart technology to bring sustainable
savings, while the latter will draw relevant
networks between academia and industry.
Altogether, this partnership will enhance the
grid of sustainable models, allowing more
companies in Singapore to benefit from a
green transformation.
Elsewhere, India must juggle the needs of
rising manufacturing industry and ensure
its people have access to clean, unpolluted
water. Enter Energy Recovery, whose, as
their names suggests, have enabled the
country to reap the benefits of industrial
wastewater treatment at low cost. With this,
India is one step closer to reducing water
pollution and enhancing the quality of life of
her people.
Regardless of nation, regardless of
industry, everyone plays an important
role in securing the future of our water
resources. As ice caps are melting at an
unprecedented pace in the most extreme
corners of the globe, while lakes are
shrinking in others, the path towards a
more sustainable road is paved by all
parties involved. And here at Water &
Wastewater Asia, we will continue to bring
you provoking stories from all corners of
the industry, in hopes that it can inspire our
readers to take the charge forward towards
a better, greener future.
In the final issue of this year, let us reflect
on the progress we made this past year,
and look boldly into the future ahead. The
glass is, after all, always full.

Xylem Water Solutions Singapore
and Gross-Wen Technologies (GWT)
have announced a memorandum of
understanding (MoU) for a new joint
R&D project to deploy algae-based
wastewater treatment solutions in
Singapore. The project will focus
on the development of GWT’s
existing revolving algal biofilm
(RAB) technology, an algae-based
wastewater treatment solution that
promotes nutrient recovery while
reducing the carbon footprint of water
utilities.
The project will feature GWT’s algaebased
treatment of anaerobic digestor
(AD) effluent for carbon footprint
reduction and nutrient recovery. This
includes atmospheric CO2 capture
by algae, low-energy nitrogen and
phosphorus recovery, and reduced
nitrous oxide emissions from the
concentrated AD effluent. The algae
produced during the process will
be harvested and used to make
fertilisers, bioplastics and biofuels.
As part of the project, the R&D
team led by Luo Rongmo, senior
development engineer at Xylem
Singapore Technology Hub, and
Martin Gross, president and CEO of
GWT, was awarded up to S$247,000
to implement a small-scale RAB
system at Xylem’s Singapore
facility during the proof-of-concept
phase of the Carbon Zero Grand
Challenge. If successful, this will
be piloted in a full-scale system for
PUB, Singapore’s National Water
Agency.
Luo said: “We are pleased to
be partnering with Gross-Wen

NX FILTRATION TO BE PART OF ACCIONA-
LED INITIATIVE TO ELIMINATE EMERGING
POLLUTANTS FROM WATER SOURCES
NX Filtration, a provider of direct water
nanofiltration technology, has announced
its participation in the European innovation
project LIFE PRISTINE. The project’s
objective is to eliminate emerging
contaminants in the integral water cycle,
which is one measure to promote alternative
water resources in the face of water scarcity.
The LIFE PRISTINE project has a budget
of €4m and is coordinated by Acciona, the
Spanish sustainable infrastructure solutions
group. Other project partners include Eurecat,
Xylem Services, the Regional Entity for
Wastewater Sanitation and Treatment of the
Murcia Region (ESAMUR) and the water utility
provider Bilbao Bizkaia Water Consortium
(CABB). The project hopes to combine water
treatment processes, such as NX Filtration’s
hollow fibre nanofiltration membranes, with
artificial intelligence (AI)-based digital tools to
develop a solution that removes the emerging
pollutants.
The project was launched in light of various
forums being alerted to the urgent need to
take steps in protecting water resources.
Such an outcome can be achieved through
reducing water consumption, but also by
promoting alternative resources and reuse.
One key issue that has been raised in efforts
to encourage water reuse is the presence
of pollutants and microplastics in water
supplies. These substances of anthropogenic
origin are difficult to eliminate when using
existing treatment systems and they may end
up in seas and rivers, or even enter the food
chain. Their presence may create hazards.
There is thus an increasing emphasis on
regulating the use of these substances and
developing solutions to remove them from the
environment.
LIFE PRISTINE thus aims to eliminate up to
80% of emerging pollutants in the endto-end
water cycle, particularly per and
polyfluoroalkyl (PFAS) substances. These
are typically found in flame retardants,
pesticides, pharmaceutical and personal
care products, toxins microplastics and
genes of microorganisms that are resistant
to antibiotics. The project aims to strengthen
the existing legislation and promote the reuse
of water with the highest possible quality and
safety standards.
The PRISTINE solution involves the
processes of adsorption, nanofiltration and
advanced oxidation using virtual sensors,
process modelling and decision-making
support tools. The machine is said to be
capable of reducing emerging pollutants from
water sources and wastewater effluent. The
PRISTINE project is set to be demonstrated
in a representative operating environment:
namely, the secondary effluent of a treatment
plant in Murcia, Spain, and supporting
drinking water pre-treatment in the Bilbao
Bizkaia Advanced Water Treatment Centre
(CATABB).
WAVIN ACQUIRES DUTCH START-UP METROPOLDER
Wavin has acquired Dutch start-up
MetroPolder, against the backdrop of
increasingly extreme weather events and long
periods of drought that have been affecting
the liveability of cities around the world.
With the acquisition, Wavin is expected to
incorporate MetroPolder’s knowledge to
close the water cycle in cities and make cities
“future-proof”.
MetroPolder has developed a technology
to capture water on roofs and reuse it for
cooling, irrigation and recycling. The bluegreen
roofs are equipped with a buffer
system, an internet-connected valve and
an online dashboard. The valves sensors
and rain radars control the water level and
discharge real-time. This smart connection
enables dynamic water storage. The
technology has been implemented in projects
over several locations worldwide, including
the Netherlands, Guatemala, France the UK
and US.
Friso Klapwijk, CEO of MetroPolder said:
“Wavin sees rainwater as a resource, not a
problem. That’s where we found each other.
We want to make cities future-proof, by
applying smart water management. Think
of reusing rainwater for for cooling cities to
combat heat stress. We are pleased and
proud to be part of the Wavin family from now
on.”
Maarten Roef, CEO of Wavin, said: “The
green/blue roof solution of MetroPolder
is a proven successful, international,
application that puts Wavin as a company in
an even better position to make cities more
climate resilient. Supplemented with the
knowledge and expertise of MetroPolder,
we are convinced that we will succeed in
getting more and more cities to look at the
applications of water differently. Because the
opportunities are plentiful.”

PERISTALTIC PUMPS GAIN IMPROVED COVERAGE IN WIMES
Watson Marlow Fluid Technology Solutions
(WMFTS) has helped with a revision of the
Water Industry Mechanical & Electrical
Specifications (WIMES), opening up
peristaltic pumps to more potential
customers in the UK water industry.
Peristaltic pumps, such as WMFTS’ range
of Qdos chemical metering pumps for water
and wastewater treatment applications,
had not previously had the benefits of their
technology explained in the specifications.
The revised WIMES now contains
comprehensive dosing pump specifications,
with a number of the benefits of peristaltic
pumps now more apparent and explicitly
covered in the latest version.
WIMES is a collaborative project managed
by the Pump Centre, aimed at providing
common mechanical and electrical
specifications for the UK water industry.
Seventeen of the UK’s largest water
companies are involved in WIMES, which
enables them to procure equipment which
is fit for purpose and provides the lowest
lifecycle costs at a competitive purchase
price.
The intention of WIMES is that the
specifications should be unambiguous and
allow individual suppliers to compete on
an equal footing, so buyers can accurately
compare and contrast suppliers.
Dale Kavanagh, industrial sales & business
development manager at WMFTS UK, said:
“The specification has been rewritten so
there is more detail about peristaltic pumps,
and their benefits compared to other pump
types. It is a huge result and has helped
develop the business this year.
“For the last two years Watson Marlow have
been working hard to ensure that the latest
version of the specifications would have a
fairer balance, showing the advantages of
WMFTS Qdos 60 and
30 peristaltic pumps
are now included in
the Water Industry
Mechanical & Electrical
Specifications (WIMES)
peristaltic pump technology. This ongoing
work has resulted in large orders from several
water companies in England.
“Watson-Marlow were able to get a seat at the
table and collaborated with water regulators,
putting the case forward on why peristaltic
pumps are beneficial. The success was a
result of a lot of hard work, in particular from
sales skills training manager Bruce Quilter
and former UK industrial sales engineer Eddie
Smeaton.”
GREATER RELIABILITY
WMFTS’ Qdos range of peristaltic pumps can
handle flow rates from 0.1 to 2,000 megalitres
a minute at pressures up to 7 bar as well
as offering repeatable chemical metering
accuracy of ±1%.
With a Qdos pump, the flow remains the same
at any pressure, providing greater dosing
control and leading to measurable chemical
and energy savings — a key difference to
other equipment on the market. The low
maintenance design also means process
uptime is maximised with no-tools, and quick
and easy pumphead replacement in situ.
A reverse function enables the operator to
drain the line before maintenance and, once
in operation, there is an integral leak detector
to eliminate the risk of exposure to chemicals.
Integration of the Qdos pump range is easier
than traditional dosing pump types as they
eliminate the need for foot valves, strainers,
degassing valves and loading valves, along
with all the relevant joints, simplifying
maintenance and enabling dosing skid
manufacturers to reduce the size of their
skids.
Roger Marlow, principal consultant at the
Pump Centre, commented on the more
comprehensive dosing pump specification
in the updated WIMES: “Water managers
and engineers of large water infrastructure
projects are looking to alternative pumping
technologies for many reasons. The
landscape of chemical metering pump
manufacturing and innovation in the water
industry is changing and it is important for
WIMES documents to reflect that.
“It has been a very positive experience
working with Watson-Marlow and we will
continue the collaboration between all parties
in the future.”
Reflecting on the current landscape of
chemical dosing equipment, Kavanagh
said: “The scale of the rollout of new
equipment makes now an ideal time for
utilities to consider the whole-life benefit of
the chemical dosing equipment they select.
As such, it is believed that Qdos pumps an
ideal solution to meet companies’ water
management challenges.”

SUCCESSFUL HANDOVER OF THE ANAEROBIC
BIODIGAT SB SYSTEM TO DEVELEY IN GERMANY
Develey Senf & Feinkost, an international
manufacturer of mustard, sauces and
dressings, commissioned Wehrle in March
2021 with the design and implementation
of a wastewater treatment plant with biogas
generation. Just one year later, in the summer
of 2022, the biological commissioning of the
industrial water treatment plant took place
at 100% capacity at the company’s largest
German production site in Dingolfing.
The Wehrle plant reduces the wastewater
pollution load in such a way that the discharge
values fixed by local authorities for indirect
discharge into the downstream municipal
sewage treatment plant are safely fulfilled.
The industrial wastewater treatment plant is
also an example for the synergetic integration
of modern environmental technology and
supports the customer’s overall sustainability
initiative by reducing production emissions.
Wehrle worked together with their customer
to develop an overall concept, including
sophisticated wastewater treatment and
reliable purification of the water during peak
loads in accordance with official requirements.
Furthermore, the integrated biogas generation
of the wastewater treatment plant together
with a modern combined heat and power
plant allows the direct conversion of the
generated biogas into electricity, which can
be used on site. The used technology is the
anaerobic high-performance BIODIGAT SB
process. With its three-phase separation
system incorporating highly efficient biogas
utilisation as well as heat pump technology
with maximised overall energy efficiencies, the
process meets all customer requirements.
The successful commissioning of the new
wastewater treatment plant was completed
almost on time, despite the difficult conditions
caused by the pandemic. The capacity was
reportedly at 100%, four weeks after inoculation
of the plant with biomass. The cleaning
result and the gas yield showed an increase
of approximately 20-30% compared to the
expected values. Intelligent control technology
enables continuous operation of the biology
and the combined heat and power plant 24/7.
Mr Reiter, technical director of Develey in
Dingolfing, was satisfied: “The robustness of
the biological process has clearly exceeded our
expectations. The high-performance system
reliably purifies our wastewater, which varies
greatly in quantity and quality, in continuous
operation. In fact, the biogas production is
so good that we are considering another
combined heat and power plant for electricity
generation.”
With this project, Wehrle claims that it has
expanded its references for anaerobic
wastewater treatment and showed its reliability
as partner in the field of environmental
technology. “We are proud to be part of this
innovative and future-oriented project as an
important system supplier and to be able to
support the customer in its long-standing
claim to sustainable operation with innovative
products, clever engineering, drive and on-time
implementation,” said Frank Natau, business
development, water processes at Wehrle.

SOFTWARE ASSET FOR WATER
INVESTMENT PLANNING LAUNCHES
The latest version of Probit’s asset
investment manager (AIM) software aims
to help water companies in England and
Wales save time and cost in planning
works to optimise geographical synergies.
AIM4 also makes web service interfacing
and more localised analysis available to
water companies and other organisations
managing large asset bases.
AIM4 is said to have set a precedent for
analysing water and wastewater assets
together. Historically, water companies
that manage both water and wastewater
infrastructure were unable to do so, as
software with the capacity to process such
vast numbers of assets was not available.
This meant work stream management
teams were not working collaboratively and
modelling was siloed.
Increasing demand for cost efficiencies
in investment programmes means asset
management challenges are being given
greater strategic importance and becoming
more complex. Ageing infrastructure,
climate change, increasing regulation, and a
growing population can all impact on asset
life.
IMPROVED FUNCTIONALITY
Reflecting on the advances of AIM4, Philip
Jonkergouw, managing director at Probit,
said: “The biggest improvements have
been to functionality, optimisation set-up
capability, and adaptability. AIM4’s greatest
strength lies in its ability to respond to the
unknown and develop accordingly.
“AIM4 has a high level of adaptability and
flexibility when clients are facing new
requirements, especially during water
utility price reviews or asset management
modelling transitions. As a result, it can
now be used to answer more and more
complicated questions for clients.”
Using the AIM software, asset intensive
organisations in water and other sectors
can model the complete lifecycle of assets,
anticipating changes and how they will
impact on services. This results in better
business decision-making that helps make
assets more resilient and reduces service
disruption and the risk of regulatory fines.
AIM4 also delivers improvements in
software functionality, such as the ability
to analyse risk per region and per asset
base. This allows users to examine factors
such as planning constraints, along with
the associated risks of not commencing
work at specific points in the future, at a
granular level.
In addition, AIM4 introduces the option of
web services, meaning AIM is no longer a
standalone piece of software with limited
client interaction. Third party systems
can now connect directly to AIM to enter,
extract, and link up data, creating an allround
tool.
AMP7 PLANNING
The regulatory asset management
period 2020-2025, AMP7, requires water
companies in England and Wales to
calculate investment needs and provide
evidence on expenditure over a five-year
period. By allowing asset managers to
explicitly model what happens to assets
under various conditions, certain questions
can be asked such as how assets will
deteriorate with how much risk and the
associated costs due to failures in the
network.
Reflecting on the growth of the AIM
software, Jonkergouw said: “Initially, AIM
was used for underground linear assets
such as sewer and water pipes, water
mains and trunk mains. Then, clients
wanted to do more types of modelling to
Probit’s asset investment manager (AIM) software is
helping water companies in England and Wales save
time and cost in planning works
include above-ground assets, such as
wastewater treatment plants and pump
stations.
“Now it can be used to synchronise works
across the whole water and wastewater
asset base, and potentially with other
sectors too. This is a perfect example of
the adaptability and flexibility of the AIM
software to meet new client requirements
and we hope to continue these strong
working relationships with AIM4 and
beyond.”
FUTURE OF AIM
AIM software also delivers digital
solutions and asset management across
other infrastructure intensive sectors
including power and transportation. The
next step is to bring other utilities into
the cross-sector optimisation work. For
example, synchronising gas works to
be done at the same location and at the
same time as planned roadworks.
“There has been ambition for this in the
past,” said Jonkergouw, “but until now
the tools, technology and processing
power were not available nor did the
sectors have the datasets needed. Now
that asset management streams have
the potential to come together in a single
optimisation investment framework in
AIM, this could start to drive cross-sector
collaboration and trials.”

RESEARCH FROM ABB SHOWS HOW
CITIES CAN TACKLE WATER STRESS
BY REDUCING CARBON EMISSIONS
AND COST OF WASTEWATER
TREATMENT FOR REUSE
ABB published the first in a series
of new reports for the energy and
wastewater sectors to highlight the
impact that technology can have
in enabling industrial customers to
reduce carbon emissions and manage
the energy transition for a more
sustainable future.
With the United Nations predicting a
40% water deficit by 2040, ABB has
conducted research to reveal how
better use of wastewater could relieve
pressure on water supplies.
When treated effectively, wastewater
can be returned to the water cycle for
reuse, proving a valuable but often
untapped resource in tackling water
scarcity. Importantly, it also lowers the
levels of untreated sewage pumped
into rivers and oceans, which have
hugely negative impacts on public
health, the environment and marine life.
“Global data shows that only half of
our wastewater is properly treated,”
said Brandon Spencer, president,
ABB Energy Industries. “Allowing
untreated wastewater back into
our water courses not only has a
disastrous effect on fisheries, animals,
marine biodiversity, and public health,
but it is also a terrible ‘waste’ of this
commodity. We need to be doing
more.”
Treating wastewater, however, requires
a lot of power, with the industry at large
consuming up to 3% of the world’s
total energy output and contributing
over 1.5% to global greenhouse gas
emissions.
Seeking to redress this balance, ABB
has conducted nine months of research
and modelling with an independent
economist, to demonstrate how greater
adoption and integration of process
automation technologies, can deliver
both carbon and cost savings to enable
more efficient treatment of wastewater.
The findings reveal that in wastewater
sites, utilities could reduce carbon
emissions by up to 2,000 tonnes per
annum, the equivalent volume of CO2
responsible for 30,000 tonnes of glacier
mass lost every year. With over 50,000
existing wastewater plants worldwide,
the opportunity, if scaled, is upwards of
100 million tonnes of CO2 saved.
Furthermore, in applying a robust
package of process control and digital
solutions, water companies could reap
annual operational savings of up to
US$1.2m (9.5%) per plant, opening
revenue streams to ensure higher
volumes of wastewater are treated and
less is discarded in our rivers and seas.
“ABB is committed to leading with
technology to preserve precious
resources such as water and energy,
and ultimately enable a low-carbon
society and a more sustainable world.
In 2021, we have reduced our own CO2
emissions by 39%, compared with the
baseline year of 2019, and as part of
our Sustainability Strategy 2030, we
are working with our customers with
the aim of reducing their annual CO2
emissions by at least 100 megatons by
2030,” said Spencer.
The global wastewater market, driven
by the need for more freshwater,
population increase, and stringent
environmental regulations, is projected
to grow from $300bn in 2022 to $490bn
by 2029.
The reports’ economic modelling
was undertaken by independent
economist Steve Lucas of Development
Economics in conjunction with ABB
Energy Industries and supported with
desktop research of academic and
industry sources. ABB will publish
further economic reports focused on
the offshore, power and chemicals
markets across 2022 and 2023.

KOOLL COMPANY, THE PHILIPPINES
Lars Enviro was contacted to design,
supply, and commission a fermented wash
(raw spent wash) biogas plant for the Kooll
Company, in Talisay City, The Philippines.
The company is one of the largest
producers of alcohol- and beverage-grade
liquid carbon dioxide, supplying to major oil
and beverage companies in the country with
a flow of 980m 3 /day at a COD of 120,000mg
per litre. The plant Lars constructed thus
generated about 34,500m 3 of biogas per
day, which was utilised as fuel in boiler.
With the plant, Lars enabled the reduction
of highly pollutant wastewater and the
ability to handle shock loads. With one
seeding and commissioning required,
there was no need for specialised culture
and nutrients for further operations, and
no need for chemicals once the plant had
stabilised
The plant was also capable of handling
a higher volume of wastewater and can
restart rapidly after a shutdown. The
biogas produced can be utilised in boilers,
canteens, furnaces, CBG, for electricity
generation. The treated wastewater, which
contains high nutrient, can be used as
organic compost to improve soil fertility,
reducing water demand and the economic
burden (inorganic fertilisers) of farmers.
THE NATIONAL DAIRY DEVELOPMENT
BOARD
The National Dairy Development Board was
set up by the Parliament of India. With its
main office located in Anand, Gujarat, with
regional offices throughout the country, the
board was created to finance, support and
support producer-owned and controlled
organisations. Its programmes and activities
seek to strengthen farmer cooperatives and
support national policies that are favourable to
the growth of such institutions.
The dairy industry is the most polluting food
industry in terms of water use during the
production of milk and milk products. The
wastewater contains dissolved sugars, proteins
and fats, which is organic and biodegradable.
Dairy wastewater is thus considered as
possessing high concentrations of organic
matter and BOD. It is estimated that dairy
industries generate 2.5-3 litres of wastewater
per litre of milk processed.
If left untreated, dairy wastewater will pollute
land and river systems. Hence, proper
treatment of dairy wastewater is necessary
before disposal in the environment, as per the
Maharashtra pollution control board (MPCB)
standards.
With experience in managing dairy waste from
companies such as Etika Dairy from Malaysia,
and Hatsun Agro Products from India, LARS
had supplied preliminary, anaerobic, aerobic
treatment, alongside tertiary treatment like
MGF and ACF. Lars provided a single point
solution to treat liquid waste water generated
from the plant, and treated water was used for
irrigation purposes.

IN CONVERSATION WITH
SUEZ EMBARKS
on 2027 goals
As the water industry is poised for significant
changes in climate, smart solutions, and more,
Agatha Wong speaks with Sabrina Soussan, chairman
and CEO of SUEZ, to find out more about the
company’s strategy in the years to come.
To begin with, can you share with us your
experience as CEO of SUEZ since your
appointment earlier this year?
Soussan: The first months have been filled
with much listening, interacting and getting
to know as many colleagues, from across 40
countries we operate in, as possible. I have
been particularly impressed by our Chinese
Team which has been working under very
difficult conditions due to lockdowns
imposed as countermeasures to COVID-19.
Over that period, we have also achieved a
number of significant milestones. We have
completed three acquisitions: hazardous
waste in France; EnviroServ, the leader in
waste treatment in Southern Africa; and
our former recycling and recovery (R&R)
assets in the UK. These moves highlight
the optimism and confidence of our
shareholders in SUEZ’s future. Once the
acquisitions are finalised, the SUEZ global
team would have grown from 35,000 to
44,000 employees and our annual revenue
risen from €7.5 to €9bn.
Can you comment on SUEZ’s new
strategy? What are some of the changes
that customers can expect from it moving
forward?
Soussan: Our plan is an ambitious one,
in line with the increasingly important
environmental challenges facing our world.
My ambition for SUEZ is that we become the
trusted partner of industrial companies and
local authorities for circular solutions in water
and waste. This strategy will progress SUEZ
towards its goals through three pillars: focus,
differentiation and enhanced value creation.
• We will focus on our core business: the
complete waste and water value chains,
including related services, and concentrate
our efforts on certain particularly buoyant
markets, such as Asia, the United
Kingdom, Italy, India, Australia, the Middle
East and Africa.
• We will differentiate by offering a unique
value proposition to our customers, built on
our proven infrastructure, on our expertise
with a recognised leadership in smart and
digital solutions, on end user experience,
and on innovation.
• We will offer enhanced value creation by
being more selective with our projects,
making digitalisation and service
excellence our drivers for competitiveness.
By 2027, this strategy will enable us to be
a benchmark in our industry, recognised
for our agility, capacity to create value, and
innovation.
SUEZ will invest an additional €860m
compared to the previous period to
address new environmental and energy
challenges. What do you think are the most
pressing issues in the industry, and how
will SUEZ continue to create differentiated
solutions to meet these needs?
Soussan: Our industry currently faces
historic challenges, characterised by
strong momentum for green transition from
governments, industries and customers.
SUEZ has been part of this evolution by taking
the lead in action and expanding its expertise.
We will continue to devote our efforts in
addressing environmental challenges
regionally in this fast-changing world. True
to our partnership culture, we will double
our investments, alongside our customers,
mobilising an additional €860m compared to
the previous period for the digitalisation of
water networks, decarbonisation and energy
efficiency, for example. We will also increase
our innovation capacity, with a 50% increase
in our R&D budget by 2027 to develop
differentiated solutions for preserving water
resources, combating pollutants, recycling,
producing green energy from waste; and
reducing our own carbon footprint, as well
as that of our customers. Digital technology
is also an important lever for improving
performance and agility and for developing
new solutions. We will continue to invest
in this area, with the goal of doubling our
revenues from these activities in five years.
18 WATER & WASTEWATER ASIA | NOVEMBER/DECEMBER 2022
IN CONVERSATION WITH
How will SUEZ work towards its strategic
objectives and maintain its position for the
future?
Soussan: As we grow strategically and
reposition ourselves to be a leading, fullservice
provider across the entire water
and waste value chains, we will have to be
selective with where we invest our resources
and which projects we undertake. Pursuing
strategic opportunities requires efficient
decisions and strong capital support. We
are fortunate to have a strong backing from
our consortium of shareholders, with ample
capital and strategic alignment.
Second, we will also need to maintain our
leadership in sustainable development.
By the end of 2022, SUEZ will unveil its
sustainable development roadmap, outlining
our contribution, ambitions, and quantified
targets for climate, nature conservation, and
social matters.
Third, we need to engage all stakeholders.
We have made a commitment for employees
to hold 10% of the capital within the next
five to seven years through an employee
shareholding plan. We are promoting diversity
and equal opportunity, and we are renewing
our social commitments through inclusion
initiatives, notably through our social inclusion
subsidiaries, such as Rebond in France.
SUEZ will also be focusing on both mature
and emerging markets. On that vein,
what are your goals for South East Asia in
particular? What unique opportunities for
growth and investment do you see in this
region?
Soussan: South East Asia is an important
region for SUEZ because of our historic
presence in this region and the rising demand
for environmental improvements and the
need to supply top class water and waste
services to the growing populations. As part
of our desire to focus our activities, we will
keep concentrating our efforts, notably in the
Philippines, Indonesia, Vietnam and Thailand,
as well as others. We have numerous projects
in these nations, managed by strong local
SUEZ’s plan for 2027

teams. Additionally, we provide them with
technical and financial support from our
worldwide SUEZ organisation. Our goal
is to expand further by working with our
partners and clients. By 2027, SUEZ aims at
generating approximately 40% of its revenue
in international markets.
Can you share with us more on the
new, simplified, and customer-focused
organisation that will be structured
around water and waste? How will this
organisation further benefit SUEZ’s
customers and deliver a more robust
commercial and operational experience?
Soussan: We plan to become a more
agile and customer-focused organisation
structured around our two core businesses,
water and waste. Globally, we will organise
our businesses as one “Water” and one
“Waste” division. Our new structure and
operating model will enable us to better
put the customer at the forefront of our
activities.
What are your hopes and visions for
SUEZ as it works towards its strategic
plans? What are you most excited about
for SUEZ’s journey in the next five years?
Soussan: I’m looking forward to seeing
this ambitious, yet realistic, strategic plan,
which is rooted in a purpose of making key
contributions to society, progressing step
by step. I’m convinced that SUEZ, through
its water and waste activities, has been
playing and will play a vital role everywhere
it operates in improving people’s quality of
life on a day-to-day basis.

IN CONVERSATION WITH
THE COLLECTIVE CALL
for sustainable action
Cooperation with government bodies, private
companies, and academic institutions will be vital
in ensuring the longevity of green strategies.
By Agatha Wong
The announcement of the Environmental
Sustainability & Energy Efficient Centre (ESEE)
by Singapore Polytechnic (SP) at the “Values-
Based Green Transition – For Singapore
Businesses” event brought together key
players ranging from government agencies,
private companies, trade associations and
chambers, demonstrating a united resolve in
supporting the green transition of companies
across various sectors.
Serving as a one-stop provider of services and
counsel for sustainable practices, companies
can expect the knowledge and expertise
of participating members as they tackle
common teething issues such as operational
costs and administrative process. Similarly,
companies like Grundfos will be tapping
into their portfolios to support firms across
various industries. The end result: a symbiotic
arrangement where all parties benefit mutually
from the expansion of greener strategies.
“The MOU with SP will allow us tap into higher
learning institutions, where Grundfos comes in
with vast knowledge and applications; as well
as experience in bringing about sustainability
solutions. SP will also provide us a platform
to also enter more ecosystems and connect
with more industries, policy makers and
higher-learning institutions, and get things off
the ground,” said Eric Lai, regional managing
director of Industry – APAC, and country
director for Singapore, at Grundfos.
On that front, Grundfos will be able to offer its
portfolio of services and products, designed
for water and energy efficiency, to a wider
audience. Humphrey Lau, former
group senior vice-president of global
industry business at Grundfos, shared
at the conference the six projects
which the company has planned,
drawing from the reduction of Grundfos’
carbon footprint by energy consumption
and the electricity bill as per prior
feasibility studies on solar panels and PV
installations. Bearing its past experience
and expertise, the ESEE will thus provide
Grundfos the context needed to support local
companies:
“In order to bring collaborations like this to
life, it is important to have a relevant context,
and that is why it is so important for us to
have collaboration with local institutions
like SP, else we’d be coming up with global
concepts that are too far away,” added Lau.
RACE TO 2030
The need for sustainable action has never
been clearer. As the 2030 deadline set out by
the United Nations Agenda for Sustainable
Development swiftly approaches, with the
organisation stating that the world is nowhere
near said goals, there is a strong call for more
to be done, and quickly. In that regard, it will
be vital for key players to help as many firms,
both large and small, as possible. On a local
level, this also means reaching out to small
and mid-sized enterprises (SMEs), which
form a critical part of Singapore business
landscape.
“Local companies have a big role to play,
because they are part of the larger industry

vice-president of global industry business at Grundfos
that consumes most of the electricity in
Singapore. For us, coming in as a global
company, it is important to engage at the
right-levels regarding using less to produce
more — both from the water and energy
aspect. Another aspect would be bringing
along digitalising technologies, having sensors

IN CONVERSATION WITH
in place; getting more shove in terms of the
consumption and demand requirements. To
regulate the energy and water consumption
on a needs-based system rather than the
previous time-based and experience-based
systems can allow us to get heart of the
issue, which is increasing sustainability and
using less for more,” said Lai.
While Singapore delivers a conducive
environment for the implementation of
sustainable initiatives, it is also necessary
for global companies such as Grundfos
to reach out to other countries around the
world. Crucially, there is also a protracted
call for enabling sustainable change in the
region. South East Asia, in particular, can
benefit from a fortification of their water
infrastructures alongside greener strategies,
killing two birds with one stone. In that
regard, the region presents a reservoir
of untapped potential and business
opportunities for water companies to lead
the change.
“For the region, we see a lot of potential to
cover the market, especially in South East
Asia. There are many cities and industry here
that can escalate their water reductions,
water efficiency and quality levels. Through
this network, we can also drive the trend in
terms of sustainability for the goodwill of
climate change. It can also bring about a
sustainable business model. This can really
fund and produce good not just for the
company, but for the environment in the long
run,” shared Lai.
Lau shared a similar sentiment: “Asia
represents an industrial hub, not just in
Singapore but across South East Asia, and
even Japan and Australia, China and India.
This will only in the coming years continue
to intensify in terms of water, energy, and
resource consumption. You can think of it
as a huge pilot plan where there is a need
for solutions. We see a huge opportunity
for Grundfos to co-develop solutions with
industry players in this part of the world.”
HAND-IN-HAND
As a global company, Grundfos has had a
front-row seat in witnessing the changes
necessary for the sustainable transformation
of the world’s industrial ecosystems. More
than that, as providers of solutions in water
and energy management, the company
has a keen awareness in the importance
of collaboration for fruitful changes to take
place.
The ESEE serves as an instance where multifaceted
cooperation across different sectors,
be it private or public, can work together
towards a common goal. This is testament to
the enormity of the climate challenge at hand,
where it is not sufficient for a single player
to contribute to the fight. For pronounced
change to take effect, it will be vital for
agencies and companies to come together in
a common goal.
With input across public
and private sectors, and
academic institutions,
the conference and
ESEE served as proof
of the need for greater
collaboration in enacting
sustainable change
Lau remarked: “There are issues and
challenges in this world which are so big that
not one company nor sector can handle by
themselves. The COVID pandemic had been
a great example showcasing how private
pharmaceutical companies can work hand-inhand
with governments to develop vaccines in
an unprecedented short amount of time.
“Climate change, I think, is another major
issue that not just one sector can work alone
on. I believe that Grundfos holds a small
number of keys and tools that can add onto
this larger equation, and we’d very much like
to invite everyone on the value chain to work
together with us.”
Quoting Dr Amy Khor, Senior Minister of
State for Sustainability and the Environment,
and Transport, who graced the event as the
guest-of-honour, and stressed the need to be
bold in the sustainability journey, Lai added
that the issue of sustainable transformation
no longer lies in the “why”, but rather the
“how”. Concrete measures demonstrating the
commitment and collaboration between all
parties will be vital to setting the path for the
sustainability agenda moving forward.
“The event demonstrates that there is a lot

IN CONVERSATION WITH
“GOOD FOR BUSINESS,
GOOD FOR COMMUNITY”:
What corporate sustainability
could look like in South East Asia
As the need to fight climate change increases, companies have to re-consider
their corporate priorities to ensure sustainability across all areas of production
and their industries as a whole. By Kimberly Liew
(COP26) held in Glasgow last year revealed
that organisations should reduce emissions
to keep temperature rises within 1.5°C, to
prevent climate catastrophe. Companies thus
need to be strategic in their plans for water
sustainability. They need to innovate solutions
to these pre-existing issues, while also
ensuring their own practices are sustainable
themselves.
This includes where they source their water
supplies. Agnihotri stated that LANXESS
regularly assesses current and future water
stress to ensure the human and ecological
demand for water is sustainable. Over 90%
of their water withdrawal are in areas with
low water stress. They have also identified
four water risk sites and have initiated
measures to reduce water withdrawal.
For companies working in South East Asia,
water sustainability is an issue that needs
to be seriously considered. Despite being
home to 60% of the world’s population, the
region only has access to 36% of the world’s
water resources, making the per capita water
availability the lowest in the world.
These challenges are only furthered by
climate change causing extreme weather
fluctuations and rapid urbanisation. The
United Nations Climate Change Conference
LANXESS: SOLUTIONS AND STRATEGY
LANXESS, a specialty chemicals developer
with solutions in water purification, is one of
the many companies which has re-oriented
itself towards sustainability. In their efforts
to be more environmentally minded, the
company has to consider their every action
and its impact on the larger ecosystem.
“Our motto is ‘Good for business, good for
community’. This is based on the conviction
that with our products and our expertise in
the field of sustainable development, we can
make important contributions: supporting our
customers, protecting the environment and
improving the quality of life for all people. In
this way, we create sustainable value for all
stakeholders. And we remain a sustainable
company,” said Vinod Agnihotri, vicepresident
and head of materials protection
products business unit, Asia-Pacific,
LANXESS.
The company has also launched a global
water programme in 2020, designed to
promote sustainable water management
and continuously improve the ways
they use water. The programme has
three primary goals: ensure global
water management, foster local water
stewardship and to ensure the company
is connected to communities “beyond
the gates”. The company hopes to
achieve each goal through enacting
these methods, respectively: transparent
reporting on water management and use,
addressing issues in local water systems,
and safeguarding the drinking water
supply of the communities they operate
in. Ultimately, LANXESS’ global target is
to reduce annual water consumption by
2% despite organic growth, while reducing
water withdrawal from locally identified
water risk sites at an absolute of 15% until
2023.
22 WATER & WASTEWATER ASIA | NOVEMBER/DECEMBER 2022
IN CONVERSATION WITH
Water is not the only form of sustainability
LANXESS is committed to. Since 2021, the
company’s sustainability committee has
been deemed the “top decision-making
body”. Since the company’s re-structuring,
it has learnt that clear and specific goals
are the best way to enact sustainability. To
that end, it has implemented three pillars
to ensure climate neutrality: purchasing
sustainable raw materials, ensuring green
logistics, and expanding its range of climate
neutral products with the “Scopeblue” brand
label.
The company has also reportedly halved
their direct emissions, from 6.5 million
tonnes of carbon dioxide equivalents (CO2e)
to 3.2 million tonnes. This was achieved
through minimising emissions from their
production and external energy resources.
LANXESS is now hoping to eliminate their
indirect emissions in the upstream and
downstream value chain by 2050. The
company has also contributed to causes like
the OneMillionTrees movement in Singapore,
planting 50 trees across the Kranji-
Woodlands Nature Way to revive the streets
with lush greenery and reduce greenhouse
gases through carbon sequestration.
WATER COMPANIES, WATER
STEWARDSHIP AND COLLECTIVE
RESPONSIBILITY
Water companies play an important role
in resolving the water crisis in South East
Asia. “With population, pollution, and water
shortages growing unabatedly, collaboration
between the public sector and water
companies must be established to turn
water-scarce cities into high-tech hydro
hubs,” Agnihotri stated.
This schema has already been implemented
in Singapore for decades, through the Public
Utilities Board (PUB)’s role in implementing
and expanding the NEWater water filtration
system, which was used to reclaim
wastewater into clean and usable water
for Singaporeans. The project’s success is
evident from 40% of Singapore’s water supply
stemming from recycled sewage, which is
expected to rise to 55% by 2060. Agnihotri
thus encouraged water companies to work
closely with the public sector and provide
insight into technologies that can expedite the
process.
But this is only one part of the solution.
Agnihotri believes that water companies
should also work with other industries like
the chemical industry to create innovative
solutions for water treatments. He cited the
example of LANXESS’ Lewatit ion exchange
resins, which were used to treat and process
wastewater across various industries.
As he explained: “We have produced ion
exchange resins that can remove undesirable
substances from groundwater to turn it into
drinking water. The principle of ion exchange
has also found a wide variety of applications
in the household. When used in water filter
pitchers, Lewatit products remove water
hardness because many people much prefer
the taste of tea and coffee made with soft
drinking water.”

ion exchange resins at
Jhagadia site, India, used
for water treatment
Water sustainability cannot be achieved
through the efforts of water companies alone,
however. Water stewardship on the part of
companies outside the water industry is also
just as important. Agnihotri emphasised that
companies should understand their collective
responsibility “in water usage, catchment
context and shared risk in terms of water
governance”. It is only by understanding
and collaborating with others that share the
same knowledge that meaningful change
can take place.
THE FUTURE OF WATER
SUSTAINABILITY IN SOUTH EAST ASIA
Currently, the two most critical issues facing
the region are securing an adequate water
supply and ensuring water contamination
is addressed at its source. Most water
technologies are currently focused on
recycling wastewater and water recovery.
While these measures are effective, it
is likely not enough to guarantee water
security and sustainability.
One key issue in water security is preventing
and responding to future health crises,
in light of the COVID-19 pandemic and
its effects on water management. Water
services should thus begin considering
sustainability and long-term resilience as
part of their infrastructure.
For instance, Agnihotri suggested the
industry can empower water service
providers with digital innovations that
are increasingly available to manage
uncertainty and enhance the experiences
of service providers and their customers.
Green recovery strategies should also be
implemented, which includes investments
in water and sanitation that will deliver
accelerated economic growth, while also
being sustainable for people and the
planet.
“Water plays a significant role ecologically
and socially beyond its role as an economic
resource. Access to water and sanitary
facilities is a fundamental human right. Its
availability and quality are global challenges
that must be addressed at a local and
regional level. Similarly, we believe that the
sparing use of water is crucial. Scarce water
resources need to be handled consciously
and carefully and viewed as an investment
in the future,” concluded Agnihotri.

REDUCING
LEAKS IN
Jakarta’s water
networks
Jakarta’s water network
before the installation of
Cla-Val pipes
In 2005, Jakarta, the capital city of
Indonesia, was losing nearly 50% of
its produced water from leakages
in their water network. At the time,
management of the network had
been privatised into two separate
concessions, with one section
being managed by Palyja. Palyja,
a SUEZ company, is the water
distribution company responsible for
disseminating water in the western and
southern areas of central Jakarta.
The section of the network managed
by Palyja extended for over 3,000km
and consisted of mainly non-metallic
piping in sizes 25mm through
24 WATER & WASTEWATER ASIA | NOVEMBER/DECEMBER 2022
IN THE FIELD
1,200mm, with unit pressure of at most 15m.
At the end of many zones, the pressure
could typically be recorded as zero for most
of the day, as the traffic appeared to be
permanently grid-locked like most cities. The
systems ranged from newly built to old and
abandoned. Non-revenue water (NRW) was
recorded to be typically 75%.
An example of the Cla-Val pressure system
used in Jakarta
The 90-series control valve by Cla-Val
One key to permanent leakage control is
to not only reduce the leakage, but to also
maintain a low leakage level. The approach
developed for the water networks in Jakarta
was successful in identifying leaks, but not
controlling them. It became apparent that as
soon as a leak had been located and repaired,
another broke elsewhere.
According to Cla-Val, the benefits of lowering
pressure has been utilised across the world,
but these applications were typically with
higher pressures. What was less known
was the effectiveness of pressure control at
mitigating leakage rates with low pressures,
which was the main issue in Jakarta.
High leakage creates high flow, which in turn
increases head loss and reduces pressure.
When the leaks were repaired, the reverse
occurred. The resulting higher pressures
increased water loss through small leaks, as
well as the increase in new leaks. It became
clear that the solution to the problem was
pressure control. However, it was unknown if
a pressure control system could be effective
with pressures as low as 10m.

IN THE FIELD
FITS LIKE A GLOVE:
Veolia supports Mölnlycke’s
sustainable network
Tucked in the industrial heart of Kedah, Mölnlycke’s newest glove factory
will not only support regional demand for medical supplies,
but also the company’s sustainable goals.
At a glance, the plant is equipped with the following technologies:
• Process Water Treatment Plant
° Multimedia filtration
° UV sterilisation
° Hydrex chemical dosing
• Wastewater Treatment Plant
° Primary treatment/clarification – Multiflo Pack
° Biological treatment – AnoxKaldnes Moving Bed Biofilm Reactor (MBBR)
° Secondary treatment/solid separation –Idraflot Dissolved Air Flotation
° Sludge treatment – Sludge thickening and dewatering
• Hubgrade Digital Monitoring System
shared Olivier Estienne, country director for
Malaysia at Veolia Water Technologies.
Inaugurated in Sep 2022, the new Mölnlycke
plant in Kulim, Malaysia, will enable the
medical product manufacturer to expand
their glove manufacturing capacity by 60%,
allowing the company to meet current and
future demand for surgical gloves. Mölnlycke
also hopes to meet its goal for reducing water
consumption by up to 50%, using Veolia’s
digitalised systems 1 .
In partnership with Veolia Water Technologies
and Engie, Mölnlycke has also implemented
sustainable energy and water/wastewater
treatment facilities at the new plant, despite
the manufacturing process for surgical
gloves being a resource-intensive one. Jean-
Christophe Guillou, vice-president of global
Mölnlycke’s latest plant
in Kulim, Malaysia, spans
across 29,164m 2
operations for gloves at Mölnlycke, had
approached Veolia for the project.
Veolia’s solutions for the plant will enable
the company to achieve a circular economy
and reduce waste in their manufacturing
processes, as well as recycle and reuse
process water both on-site and/or via third
parties.
“What is difficult when it comes to wastewater
treatment for industrial use is understanding
what is being manufactured and what kind
of wastewater is generated. Our process
included visiting the existing team and the
facility, to see what was the best sustainable
design that Veolia could bring for the plant,”
“Sustainability at Veolia entails enabling our
customers to conserve resources. This can
be water, power, or chemical resources.
Glove manufacturing requires a lot of
chemicals, similar to wastewater treatment.
At each step of glove production, water is
needed, and wastewater is generated. The
idea was to find the best possible way to
segregate wastewater such that we didn’t
have to apply the full process to each
part of the stream. In this way, energy and
chemical consumption is reduced to what
is needed for treatment. If we start diluting
polluted water, for example, we’d need to
treat a higher volume of water. However,
if we treat only a small, concentrated
amount of water, we will only need to bring
in the chemicals needed for that volume,”
explained Estienne.
Another aspect of Veolia’s sustainable
model was embedded in Mölnlycke’s
26 WATER & WASTEWATER ASIA | NOVEMBER/DECEMBER 2022
IN THE FIELD
schema for the Kulim plant itself. As the site
will be built in stages, Veolia will match their
services to its corresponding phases. The
first stage saw Veolia helping Mölnlycke
comply with discharge standards, while
the second will aim at improving water
reuse and striving towards the goal of
zero water discharge. Altogether, these
implementations will support Mölnlycke
in their efforts towards reducing carbon
footprint.
A DIVE INTO THE KULIM PLANT
Water and wastewater treatment begins
in the Process Water Treatment Plant,
which includes multimedia filtration and
UV sterilisation. Within this process, raw
water from Syarikat Air Darul Aman (SADA)
is treated chemically before it flows into
the multimedia filter (MMF), at a flow rate
of 100m 3 /h with more than 2mg per litre of
chlorine. To comply with stringent bacterial
count requirements, UV disinfection is
deployed as the last treatment step prior to
consumption at the glove production line.
The objective of this stage is the reduction
of total suspended solids and bacteria
count.
Meanwhile, the wastewater treatment
plant has been distinguished into three
different stages and objectives. In the
primary treatment and clarification stage,
wastewater from the surgical glove
production line flows into the Multiflo
unit. Sedimentation begins here where
suspended solids and specific minerals
are blended with coagulants to form large,
easily settled flocs. These flocs accumulate
at the bottom of the equipment while
clarified water flows to the next phase for
further treatment. Here, total suspended
solids and zinc are reduced, and the
accumulated sludge in the bottom of
the tank is regularly removed either via a
suction draw-off or scraper mechanism.
After sedimentation, the clarified
wastewater flows into the biological
MBBR tank for biodegradation. In this
1
2
biological treatment stage, Veolia’s biofilm
carriers move freely by aeration, while
microorganisms feed on contaminants
and further purifies the water as part of its
biological activity. Ammonia, nitrogen, and
BOD/COD are removed as a result.
The wastewater stream is then preconditioned
with coagulant and flocculant.
This is where suspended solids are brought
to the surface of water via microbubbles as
part of the enhanced separation, through the
Idraflot dissolved air flotation. Floated sludge
is then scraped off from the water surface.
Thereafter, sludge from the Idraflot and
Multiflo is then chemically conditioned for
further thickening before being pumped into
the filter press for dewatering. The aim is to
achieve 20% dryness of dewatered sludge.
THE WIDER AGENDA
Mölnlycke’s wastewater treatment
processes forms part of a greater plan for
resource conservation in Malaysia. The
recent 12th Malaysia Plan highlighted the
government’s plans for comprehensive
water transformation, with integrated
wastewater treatment plants to be
constructed for the management and control
of effluent discharge in industrial areas, and
encouraging a circular economy in the water
sector.
“What the government wants is closely
aligned to what multinationals have set
as their KPIs; it is also similar to what the
people want. Reducing consumption and
addressing water scarcity constraints
are the most pressing factors — though
Malaysia receives a lot of rain, water is
distributed unequally across the country.
Klang and Kuantan, for example, face water
scarcity issues annually. Similarly, with more

the MBBR tank, where biofilm carriers remove
BOD, ammonia, and nitrogen
2 The Idraflot removes suspended solids, oils and
greases, and insoluble COD
industrial facilities being built in Kluang and
Penang, water resources are expected grow
tighter.
“The target, then, is to ensure that we do not
overuse water reserves. Veolia provides its
clients with access to the water they need by
preserving and replenishing them. With that,
we’re pushing wastewater reuse, which can
be applied across a variety of applications,
be it landscaping, flushing, or drinking.”
With the government leading the way forth,
and multinationals such as Mölnlycke
setting the tone for a greener future, the
Kulim plant was a success for all involved
across the board. Estienne also attributed
this to the planning team’s adherence to its
sustainability targets and its criterion-based
decision making hastened the construction
process. As the plant begins the first phase
of its operations, Veolia is keen on working
with the company further to get a stronger
grasp on what will be needed in the years
moving forward.
“Our on-site team will continue to work
with Mölnlycke to monitor and study their
wastewater streams over the coming years
— especially if there are changes to the
composition of the wastewater produced.
This way, we can provide solutions to
address Mölnlycke’s needs and achieve their
long-term sustainability targets.”

THE FUTURE FOR PUMPS,
IIoT and Industry 4.0
Elektra is an IoT-enabled
digital controller produced
by Seko which allows
operators to programme their
equipment, as well as access
live and historic dosing pump
data on demand from any
location via smartphone
Outside of the consumer sector, a branch
of IoT has emerged within industries,
including manufacturing, healthcare and
water treatment. Known as Industry 4.0 or
the Industrial Internet of Things (IIoT), the
integration of technology in physical devices
can help managers make improvements to
operational efficiency, energy consumption
and environmental impact.
This technology is changing what is possible
in traditional motor-driven, solenoid and
peristaltic pump applications, including liquid
transfer and chemical dosing in processes
as varied as swimming pool, wastewater and
cooling water treatment.
From flocculation and coagulation to pH
correction and other water-treatment
applications, operators seeking to improve
efficiency and sustainability are increasingly
specifying for web-enabled pump systems.
For example, the capacity for “live” document
sharing creates the potential for equipment
manufacturers to update digital installation
guides and operating manuals to reflect
changes in design or software, before
immediately uploading the latest revisions to
the cloud.
As the fourth industrial revolution approaches
its second decade, we are witnessing a swift
development that began within the consumer
market and is now progressing into the
manufacturing and industrial automation
sectors.
This technological growth, commonly
referred to as the Internet of Things (IoT), is
a meeting between smart device technology
and data generation, processing and
accessibility. Within the consumer sector,
this has resulted in the creation of the smart
home, where users benefit from the ability
to remotely control a multitude of household
appliances — from lighting and heating to
kitchen appliances, security devices and
entertainment systems — via computers,
smartphones and tablets.
And there is no sign of this boom slowing
any time soon, as Statistica estimates that
the worldwide installed base of internetconnected
devices will increase from 10
billion today to more than 25 billion by the end
of the decade 1 .
This allows potentially unlimited changes to
be made, saving on printing costs. Engineers
and operators can thus have access to upto-date
literature. In addition to accelerating
installation, set-up and commissioning,
managers can reduce associated time and
costs, while helping to ensure a smoother
user experience.
During equipment operation, IoT systems
receive information from pump sensors which
are constantly harvesting data on multiple
values — including cycle status, chemical
WATER & WASTEWATER ASIA | NOVEMBER/DECEMBER 2022 29
FOCUS
consumption and vibration monitoring. With
both historical and real-time data at their
fingertips 24/7, users can make informed
decisions relating to system performance and
perform adjustments to formulas, flow rate,
unit of measure and other parameters, as well
as altering pump operating modes such as
manual, batch and timed.
In addition to making efficiency
improvements, operators are able to budget
with greater accuracy and confidence while
streamlining stored chemical volume, which
is useful on small sites where space is at a
premium.
Moreover, web-connected pump systems
have the capacity to convert chemical
consumption volume into the equivalent
financial value, which allows projected
savings to be precisely calculated when
considering dosing adjustments. These
figures may also be presented to senior
management to justify programme changes
or to demonstrate performance improvement
in monetary terms.
Many pre-Industry 4.0 dosing pump systems
incorporate some form of a fault-logging
system, with the drawback being that these
are not always checked regularly, let alone
actioned. This is often a consequence of
the reactive “if it is not broken, do not fix
it” philosophy, where apart from minimal
maintenance, equipment may be left to run if
there are no visible issues and processes are
operational.
Now, IIoT-based systems enable users to
receive smartphone notifications as soon
as faults occur, meaning defects can be
quickly identified and remedial action can
be scheduled to take place outside normal
operating hours, when disruption can be
minimised. This yields an improvement in the
efficiency of equipment maintenance, repair
and upgrade planning, while avoiding costly,
inconvenient and unplanned downtime.
As well as overall system health, IIoT
technology allows for the performance and
status of specific pump components such
as bearings, couplings and belts to be
assessed. This means that the operator can
be alerted quickly should a part be due for
replacement, facilitating maintenance while
also driving aftermarket sales for suppliers.
Meanwhile, this component and system
data allows manufacturers themselves to
benefit from IIoT by monitoring trends, user
preferences and common problems, all to
refine equipment and continuously improve
their product offering.
It is not only the efficiency of equipment
and utilities that can be improved. For
businesses running across multiple sites in
different countries or even continents, IIoT
and the leveraging of real-time data means
operations management can be carried
out anywhere in the world and still be as
effective as they would be while standing in
front of the machine’s controller.
An example of how this technology could
be implemented can be seen in Elektra.
Elektra is an IoT-enabled digital controller
produced by Seko, a manufacturer of
chemical dosing systems for multiple
industry sectors, including the design,
production and supply of equipment
for processes such as potable water,
swimming pool water and cooling
tower water treatment. Elektra allows
operators of water treatment processes
to programme their equipment, as
well as access live and historic dosing
pump data on demand from any
location via smartphone. This allows
managers working remotely to analyse
pump performance and make instant
programming adjustments to save energy,
water and chemicals, while reducing the
environmental impact of their application.
The ability for one operator to remotely
manage pump systems across multiple
sites may also be useful for addressing the
water treatment sector’s well-reported lack
of skilled technical personnel caused by
retirements in an ageing workforce 2 .
This is especially true for water treatment
systems in smaller communities, where
lone, long-serving operators may possess
extensive knowledge of idiosyncratic
systems that may not be recorded or
documented. In those situations, a sudden
retirement, illness, or period of extended
leave has the potential to impair system
operations.
Additionally, wasted journeys by technicians
— who may travel a considerable distance to
assess a pump’s condition as part of routine
maintenance, only to find it in perfect working
order — can be minimised, as engineers need
only be deployed when required.
This is particularly timely post-COVID, where
the trend of remote working established
during the pandemic has seen many
operators continue to work at least partially
from home. The integration of IIoT is thus
starting to be seen as an expectation, rather
than a bonus.
The influence of IIoT on the pump industry
is positive and as technology advances, will
seemingly make life easier for operators.
However, as with most devices, connecting
pump systems to the internet immediately
makes them vulnerable to cyber-attacks,
where just one security breach can have a
potentially devastating impact on safety, cost
and reputation.
It is therefore vital that equipment
manufacturers employ robust processes
when designing secure products and back
them up with training and ongoing support for
operatives.
At a time when 5G is opening yet more
possibilities for high-speed, reliable IoT, the
global pump industry is primed to see where
technology will take Industry 4.0 in 2022 and
beyond.

WASTEWATER TREATMENT:
A deep dive into new technologies
A vulnerable climate and growing population
will call for stronger water infrastructure.
Precise
measurements
using data collection
and high sample
volumes displayed
on the Valmet Bridge
control unit.
Global warming and a changing
climate will continue to have disruptive
and unpredictable effects on both
our drinking water sources and
communities. Some places will
experience increased frequency and
intensity of rain, floods, and sewer
overflows while other areas will face
severe droughts, water scarcity and
increased fire risks.
Climate change brings severe consequences
or countries across the
globe, ranging from damage to water
supply and sewerage infrastructure,
to the degradation of catchments
and contamination of water supplies.
In Asia, climate models indicate that
rising temperatures will increase heavy
rainfall during the rainy seasons and
extend the dry durations during dry
seasons.
Equally concerning are storm surges
and high tides that could combine with
rising sea levels and land subsidence
to further increase flooding in many
regions and overwhelm the design
capacity of municipal stormwater
management systems. Stormwater
runoff, which often includes pollutants
like heavy metals, pesticides, and
nitrogen, can end up in rivers, streams
and bays.
“This contamination can be detrimental
to human health and the aquatic
ecosystem, and it will become more
expensive to clean water and bring it to
safe, acceptable drinking standards,”
cautioned Nalin Amunugama, general
manager of BOGE Kompressoren Asia
Pacific.
The global water consumption rate
has been increasing by 100% every
20 years, reported Business Wire.
The rising scarcity of potable water,

coupled with the growing population
and increasing water demand is a major
factor driving the demand. Asia-Pacific
currently accounts for the largest
share of the water and wastewater
treatment technologies market. The
high market growth is attributed
to rapid growth in population and
urbanisation, increased environmental
deterioration, increased demand
for water treatment technologies to
provide clean and potable water, and
the rise in the number of investments
in water infrastructure by public sector
organisations in the region.
The COVID-19 pandemic has also reinvigorated
the critical value of resilient,
sustainable and reliable water and
wastewater infrastructure. Municipalities
and industries around the world
are investing more in research and
chemicals that manufacturers use in
wastewater treatment. Using the data,
the operator can adjust mechanisms
and treatment processes to stay

Compressed air has an important role
in clean water supply and wastewater
treatment where different pressures
and degrees of purity are required. In
a collaboration with Belgium’s Waterlink,
BOGE equipped the Spaarbekken
Eckhoven reservoir with an aeration
system.
The plug-and-play container,
constructed at the BOGE facility in
the Netherlands, was fitted with two
frequency-regulated 22kW BOGE screw
compressors with a control range
of 1.47–4.58m³/min and a maximum
system pressure of five bar, placed at
an outdoor location. The compressed
air passes through the refrigerant dryer
to dry the air to a pressure dew of +3
degrees, and then through BOGE’s
Bluekat converter to provide oil-free
compressed air which is pumped into
the water through five-point aerators.
The aeration ensures good mixing,
leading to increased oxygen content,
reduced release of nutrients by the soil
and elimination of dead zones. This,
in turn, limits the possibility of floating
layer-forming cyanobacteria and
assures safe drinking water.
SUSTAINABLE WATER TREATMENT
Producing everyday goods generates

both the wastewater and waste from
the fishing industry. The approach
requires less energy than traditional
cleaning methods. The waste sludge
generated can also be reused to
produce biomethane instead of being
burned or sent to a landfill. Chemicals
and energy use are reduced, providing
a cost-effective and greener
wastewater treatment solution. The
emissions reduction of up to 9,000
tonnes is equivalent to the amount of
carbon dioxide that one million pine

KEEPING CLEAN WATER SAFE
The availability of safe and sufficient

In recent years, societal and

Stagnation is probably the most critical
factor in the propagation of opportunistic
pathogens. National and international
regulation bodies such as the World Health
Organization (WHO), the European Centre for
Disease Prevention and Control (ECDC), the
Health and Safety Executive (HSE) and the
ISSO, widely agree that the primary factor in
the deterioration of water quality in buildings
is directly attributable to stagnation. Recent
studies from microbiome research show that
just 12 hours of stagnation is sufficient to
cause an increase in bacterial numbers*.
During periods of stagnation, prolonged
contact of drinking water with the piping
system materials such as the pipe, valves,
and fittings can lead to a concentration of
nutrients via migration from the material
components into the water itself. A
combination of poor material quality — such
as material that does not conform to BS EN
16421* or WRAS regulations* — stagnation,
and unfavourable water quality can promote
a strong biofilm development*, in which
opportunistic pathogens — characteristically
called opportunistic premise plumbing
pathogens (OPPPs) in international
literature — can multiply. Stagnation creates
propagation advantages for these OPPPs, as
there is no dilution or removal of the nutrients
or planktonic micro-organisms entering the
water body. Nutrient discharge from materials
in contact with drinking water must thus be
reduced as much as technically possible. It
is thus the responsibility of the designer and
installer that all materials have been checked
and approved for their “microbial suitability”
for the water installation.
In addition, the effects of environmental
temperature should be considered. During
stagnation phases, the temperature of the
water will adapt to the temperature of the
ambient air surrounding it, even with standard
insulation of the pipes. This becomes a
problem when the surrounding ambient
temperatures are in the optimal propagation
range of the pathogens. Low temperatures
provide the pathogens with poor or no
growing conditions. Temperatures close to
the growth optimum allow for rapid growth.

Cold water circulation was first
realised in the main distribution
lines of cruise ships. In Germany,
numerous pilot projects have
delivered positive results in terms of
functionality and cost-effectiveness,
while achieving a mostly permanent
circulated temperature for cold
drinking water below 20°C.
For a cold water circulation
system to be implemented in
conventional plumbing installations,
an additional piping system must
be set up. This is not necessary in
installations that contain flowsplitters,
as the loop piping system
already available for the forced
flow water exchange can be used
for the water circulation. Existing
Kemper KHS systems can often be
switched from flushing technology
to cold water circulation with little
effort, as shown in Figure 1.
In contrast to conventional single
pipe cold water installations, flowsplitter
installations enable good
temperature control in all parts of
the pipe, right up to the connections
of the outlets.
Calculations with German insulation
standards taken into account show
that due to the small temperature
differences between the ambient air
and the cold water, the heat input
— and thus also the performance of
the required refrigeration unit — is
relatively low, only up to 3W/m pipe.
The KHS Coolflow cold water cooler
from Kemper, as shown in Figure 2,
removes the heat from the heated
cold water and dissipates it.
The pre-assembled compact unit with
integrated pump contains the required
components for cold water circulation
and cooling, in addition to being
diffusion-tightly insulated and preconfigured.
It can be connected to
existing cooling systems in buildings,
or connected to a KHS CoolFlow
Chiller, as depicted in Figure 3.
In hot water circulation, the
temperature differences between
the water temperature and the
ambient temperature are high. A
higher circulating flow rate is thus
required to maintain the required
temperatures. By contrast, the
temperature difference between cold
water temperature and the ambient
temperature is much lower. Volume
flows required for temperature control
in cold water circulation systems are
therefore rather low. For this reason,
the regulating valves required for
hydraulic balancing have a very low
kV value. In addition, the increasing
concentration of water constituents
must be counteracted by a targeted
water exchange during prolonged
circulation operation without water
withdrawal. Kemper has developed a
special valve in which the functions of
flushing, regulating and shut-off are
combined, as shown in Figure 4.
CONCLUSION
To reduce the ambient heat transfer to
cold water systems, passive thermal
decoupling measures should first
be used. Even with good thermal
decoupling measures, during
summer months with incoming water
temperatures above 20°C and room
air temperatures above 25°C, the
temperature of cold water is expected to
rise above 25°C. DVGW water information
90, BS 8558, HTM04-01 and other
international regulations agree that a safe
temperature for cold water is considered
to only be below 20°C. Passive measures
alone are not sufficient to achieve this.
An active process is therefore required
to ensure that a temperature limit for
cold water is met by the operator at
any time. Cold water circulation and
cooling combined with a flow-splitter
installation is recommended as an
optimal and cost-effective solution.
With products like the Kemper CoolFlow
system, a pre-determined temperature
of cold water of below 20 °C can be
mostly ensured at any time, right up
to each tapping point, even during
summer and without water losses, due
to temperature-based flushing. Together
with solutions for the circulation of the
hot water, water hygiene can be ensured
in both cold and hot water services.
Such solutions can be considered a
part of a proactive, preventive regime
that avoids hygienic deficiencies within
these water services. It is recommended
that planners and manufacturers
agree clearly with the client on which
temperature requirements for cold
drinking water should be met. On the
basis of this agreement, appropriate
passive and active measures have
to be planned and implemented in a
structural manner. If water installations
are built without active processes for
temperature monitoring and control, it
can be assumed that valid temperature
requirements from relevant regulations
can no longer be met in the future.

scarcity due to climate change, this social
impact cannot be overlooked.
Inaction on reducing NRW will only
compound to higher costs, and it is
imperative that governments prioritise
sustainable long-term NRW reduction plans.
Through Infrastructure Asia and the World
Bank Group’s regular capacity-building
programmes and identification of suitable
financing and technology solutions to
address regional NRW, we have identified a
three-enabler approach that governments
can adopt to guide their NRW programmes.
A FORWARD-LOOKING STRATEGY
Firstly, top-level management support is
crucial to set clear strategic targets and
advocate NRW reduction programmes
to all stakeholders. NRW reduction is a
long-term commitment, and a combined
effort from stakeholders at different levels
is needed.
Utility authorities should then establish
a dedicated and permanent team to
develop future-ready NRW reduction
roadmaps. This team will sustain progress
by prioritising implementation efforts
and deploying suitable investments. To
ensure the programme reaps maximum
benefits, this team should be entrusted to
monitor success and appropriately adjust
investments where necessary.
42 WATER & WASTEWATER ASIA | NOVEMBER/DECEMBER 2022
FOCUS
Given these responsibilities, the programme
needs a team that has the capabilities to
oversee the entire water infrastructure
lifecycle. Utility authorities should aim to
build capacity in the areas of law, regulatory
frameworks, project planning, technology and
technical capabilities. Regular collaboration
and investment co-sharing across public
utilities will also be beneficial in building these
capabilities.
SECURING THE RIGHT RESOURCES
Selecting the right mechanisms to resource
this strategy can also strengthen NRW
reduction outcomes and programme
management. Utility authorities should make
informed decisions on financing tools based
on project requirements, public-private
partnerships and risks. Facilitators like
Infrastructure Asia can intervene by bringing
together experts from relevant domains to
help bridge financing gaps.
Developmental financing is a useful
foundational tool to consider. Development
finance institutions (DFIs) such as the World
Bank Group and the Asian Development
Bank provide helpful mechanisms such
as equity participation, guarantees and
technical assistance to fund NRW reduction
programmes with high risk.
To further plug the financing gaps, utility
authorities with strong public-private
partnerships can explore private sector
financing to form a blended finance model.
By tapping on high liquid international private
capital such as the Climate Invest Two (CI2)
fund, utility authorities can appropriately fund
activities along the water infrastructure value
chain.
Another mechanism is performance-based
contracting (PBC), which incentivises private
companies to deliver NRW outcomes more
efficiently and innovatively by granting
contractors more flexibility in implementing
solutions. Through this option, contractors
are reimbursed based on their NRW
programme performance. This option was
utilised successfully in Ho Chi Minh City’s
NRW reduction efforts, with the city saving an
impressive 122 million litres of water daily.
EMBRACING BEST FIT TECHNOLOGIES
Utility authorities can also explore applying
technologies such as artificial intelligence (AI)
or machine learning to water production and
distribution. Utility authorities should evaluate
current processes and identify digitalisation
opportunities, as doing so can improve NRW
programme outcomes such as operational
efficiency, monitoring accuracy and cost
management.
There are many exciting potential
applications. For example, digital control
systems and AI can improve the productivity
of monitoring teams by identifying big leakage
points and prioritising pipe rehabilitation
efforts. Commercial losses can also be
reduced by using digital water meters and
online data monitoring services to monitor
meter performance and functionality more
closely. Finally, sensors could be used to
improve pressure management by modulating
water supply and ensuring maximum asset
lifetimes.
THE NRW SUCCESS OF MALANG CITY
To demonstrate the strength of this approach,
utility authorities can learn from Indonesia’s
Malang City. In exemplifying the three-enabler
approach, the East Javan city was able to
reduce NRW by 30%. This amounted to
savings of more than 70 million m 3 of water
and about $24m in revenue in 10 years,
improving citizens’ access to potable water.
Malang City’s utility authorities, known as
Perusahaan Darah Air Minum (PDAM) Tugu
Tirta, first received strong management
support to formulate a 10-year plan and
roadmap. The PDAM secured more than
5bn rupiah (US$4m) to begin the
transformation of the city’s water
infrastructure and facilities.
A team with relevant capabilities was also
created. With experience in deploying
infrastructure digital solutions, they worked
with private sector partners to set up virtual
distributed meter areas (DMA) in critical
zones. This allowed them to digitalise their
assets, enabling real-time monitoring of water
leakages to prioritise leak repair efforts with
minimal manpower.
Following its initial success, the PDAM
Tugu Tirta further optimised its operational
efficiency by setting up a 24/7 command
centre and deploying sensor technologies
to better manage water pressure
management and detect active leaks. On
top of contributing to a lower NRW rate,
these digital capabilities enabled the PDAM
to decrease overall commercial losses by
speeding up water leakage fixes to just one
day.
COMING TOGETHER
For many developing societies, water is
a crucial resource that needs to reach all
segments of society safely and sustainably.
Ideally, it should also deliver optimum results
for a country’s economy and infrastructure.
Reducing NRW is key to these outcomes.
Moving forward, it is important that utility
authorities around the world share knowledge
to address NRW and similar challenges.
Malang City’s has shown that there are many
valuable lessons to be shared with other
Asian cities, who can adapt them to solve
similar local issues. With that, Infrastructure
Asia and the World Bank Group will be
working closely together with more cities to
scale similar non-revenue water successes in
the region.

wastewater being the major contributor
to this problem. The industrial sector is
India’s largest non-agricultural consumer
of water and a 2019 study found that
industrial demand is growing faster than
any other sector. Thus, if left unchecked,
India’s manufacturing sector will continue to
compound India’s water problems.
The seriousness of these issues can clearly
be seen in one of India’s largest cities:
Chennai.
Energy recovery devices, including the PX Pressure Exchanger and Ultra PX, can reduce the
energy costs of UHPRO processes
UNESCO’s 2017 World Water Development
Report has declared that “[i]n a world where
demands for freshwater are ever growing, and
where limited water resources are increasingly
stressed by over-abstraction, pollution and
climate change, neglecting the opportunities
arising from improved wastewater
management is nothing less than unthinkable.”
Since that report five years ago, wastewater
management and treatment have only become
more critical. In fact, it could prove to be the
solution for countries like India seeking to
balance industrial growth with rising water
needs.
In 2014, India launched the “Make in India”
programme, with the goal of transforming the
country into a global manufacturing leader.
Before the pandemic, India’s manufacturing
sector accounted for about 17% of GDP.
Through efforts such as this and other
investments, India aims to increase industry’s
share of GDP to 25% by 2025.
Driving growth at this scale presents many
challenges, the chief among them being the
need for water.
India already grapples with challenges in
meeting water demand. The World Resources
Institute lists India as the 13th most water
stressed country in the world. The numbers
are stark: 600 million Indians face high to
extreme water stress, and about 200,000 die
every year from inadequate access to safe
water.
Current estimates find about 70% of surface
water in India is unfit for consumption, with
Despite sitting between three major rivers,
Chennai increasingly relies on desalination
and water piped in from distant areas to meet
local demand. This is because the majority
of local water is contaminated, often due
to inadequate or non-existent wastewater
treatment.
Currently, the vast majority of wastewater
goes untreated, with the goal is to implement
new solutions to improve the freshwater
supply and reduce pollution.
The chronic water shortage became a crisis
in 2019 when Chennai’s reservoirs ran dry
and city officials had to truck in 10 million
litres of water each day. This is hardly an ideal
situation for meeting the needs of everyday
citizens, nor is it supportive of ambitious
industrial growth targets.
However, there are new solutions available,
namely next-generation water treatment

technologies that can increase fresh water
supply while addressing pollution. Chennai
illustrated this through the adoption of
new regulations aimed at cleaning up
waterways and protecting groundwater
through greater use of minimal liquid
discharge or zero liquid discharge (MLZ/
ZLD) wastewater treatment.
MLD/ZLD technologies have advanced
significantly in recent years. However,
there has long been a major hurdle to
widespread adoption: the energy intensive
and costly nature of ultra-high pressure
reverse osmosis (UHPRO), which is at the
heart of many processes that meet MLD/
ZLD requirements.
New technologies like the Ultra PX are
changing this. The application of pressure
exchanger technologies can reduce the
energy needs of UHPRO processes, delivering
cost savings. For example, a lithium-ion
battery facility in China was able to reduce
energy consumption in the high-pressure and
ultra-high pressure treatment processes by
51% by utilising the Ultra PX and PX Pressure
Exchanger.
The same technology drove major decreases
in the cost of high-pressure reverse osmosis in
desalination, lowering the cost of freshwater in
water scarce regions around the world over the
last several decades. It can do the same for
wastewater. Higher water treatment standards,
starting with MLD or ZLD requirements for
industrial wastewater, can be not only an
affordable option, but also a game-changing
one. Indian cities like Nagpur have begun to reap
the benefits of industrial wastewater treatment:
a public-private partnership that embraced
industrial wastewater treatment for a power plant
reduced net freshwater extractions by the power
sector, freeing up freshwater resources for other
uses by around 47Mm 3 per annum.
Through greater adoption of these standards
and the technologies available to achieve them,
India can meet its economic ambitions, all
while reducing pollution, increasing access to
freshwater, and improving the quality of life of its
citizens.

GODIGITAL WATER:
The digital transformation of a
local water authority
By Lee Cher Hau, business consultant at YNY Technology
The water industry continues to face
challenges in serving its customers.
Some of these challenges relate to
droughts and floods which affect
many regions around the world and
represent the industry’s biggest
challenges.
But there are other pressing issues as
well, ranging from water scarcity, high
energy costs, water quality, water
cuts and more. Take a look at nonrevenue
water — water produced and
lost before it reaches the customer.
There can be significant losses
through leaks or apparent losses
through metering inaccuracies.
CAN WE ANTICIPATE, PREDICT

Now, imagine that these challenges
could be anticipated and mitigated
against with a range of viable
solutions. What would this present
to us? This is where Industry 4.0
comes in, with a promise of increased
visibility and performance, all driven
by data.
The revolution is here, and it is present
in the ways that some companies are

create and deliver products and services
and make improvements throughout
their enterprise and their supply chain.
Progressive companies are integrating

Industry 4.0 delivers this promise
through the creation and maintenance
of a robust and secure digital
command centre.
WHAT DOES A DIGITAL
COMMAND CENTRE DO?
Simply put, a command centre
provides a centralised command,
coordination and decision making hub
that supports day to day operations.
Centralisation helps the company to
perform numerous tasks quickly and
effectively.
Should circumstances shift, the
command centre is able to gather
insights and data to enable it to better
respond (predict and mitigate against)
small issues and major crises, using
a set of predefined objectives and
measures.
WHAT HAPPENS IN A DIGITAL
COMMAND CENTRE?
The command and control function
would involve management by
objectives and reliance on an incident
action plan. There would be a chain
of command, a common operating
picture developed, decisions
made and tasks assigned and the
prioritisation, deployment and tracking
of critical resources
Coordination and intelligence would
involve internal coordination between
executives, teams or departments
while external coordination may involve
local authorities or other bodies
Documentation management would
assist traceability and analysis and is
the basis for task assignment, incident
logging, response actions and creating
a timeline of activities.
A digital command centre can be
utilised in a number of settings and
across different sectors. It integrates
multiple systems to correlate and
contextualise data. A real-time
optimisation system could be used
to provide real-time monitoring of
KPIs in order to respond accurately
to various scenarios. It could even be
used for mobile applications, especially
in a maintenance environment. In a
manufacturing environment, it can be
used to ensure production compliance,
product traceability and job execution.

relationship between
water, energy, food
and materials
Water, energy, food and materials
are the basic building blocks for
human survival and progress. Since
the industrial revolution, these
raw materials have enabled mass
manufacturing, rapid urbanisation
and economic development. These
elements are closely linked to one
another and form a complex nexus
of relationships. For example, water
is used in the urban environment
for domestic, commercial, industrial
and urban farming activities. At the
same time, it is also used in energy
production, including a significant
amount in refineries. Often, how well
cities manage these resources has a
direct result on the city’s social and
economic well-being.
Fig 1 illustrates how each element is
involved with one another and how
the output generated from one can
be diverted into another. In many
cases, these four elements compete
for the same limited resources in
a city, including political attention,
policy priorities, land space and
budget allocations. Adding to the
complexity is the knowledge that
any decision made will affect the
climate and carbon emissions,
CLOSING THE WATER LOOP
Starting as a sustainability
solutions provider, Ecosoftt has
enabled buildings and industries
to become more water-secure by
conserving water and recycling
used water in a decentralised
manner. This is made possible
through its concept of managing
water “from source to source, at
source” and “fit-for-purpose reuse”.
In its basic form, water sources
are diversified and used water is
treated at its source and delivered
back for reuse to its most viable
extent.
For example, sewage and industrial
effluent can be recycled for
cleaning, irrigation, landscapes,
urban farming, toilet flushing,
cooling tower make-up and
industrial production uses. The
cost of treatment and safety factors
will be taken into consideration
when matching recycled water
for reuse applications. Heavy
capital investments within the long
pipeline of distribution can thus be
reduced or deferred, while the load
on municipal treatment plants is
reduced.

and food production plants.
SMART, CLOSED LOOP SUSTAINABLE
ESTATES FOR ENERGY, FOOD AND
MATERIAL
Ecosoftt is now extending this Water WISE
Buildings and Industries model to close multiple
resources loops, namely energy, food and
material within the built environment, as seen in
Fig 4.
Fig 2: Ecosoftt’s
Water WISE Buildings
and Industries.
CLOSING THE ENERGY LOOP
The inclusion of solar energy, along with other
renewable sources in the energy mix is now
commonplace. Initiatives are currently being
embarked on to develop hydrogen and other
cleaner sources of energy.
Besides finding more sustainable sources of
energy, there is potential to recycle energy by
tapping waste heat, which is plentiful in many
buildings and industries. For example, in many
factories, a lot of waste heat is generated
from cooling systems used. This waste heat
could be used to pre-heat water. There is also
potential in recovering energy from wastewater.
Improvements have been made to technologies
such as anaerobic processes, and they can
become commercially viable at smaller scales
in the future.
CLOSING THE FOOD LOOP
Buildings and industries are now capable of
becoming sites for smart urban farms and
locations for production of nutrients that can be
made from the waste they generate.
Fig 3: Ecosoftt’s
model for smart,
circular estates for
energy, food and
material
Fig 2 depicts Ecosoftt’s Water WISE Buildings
and Industries platform that aims to capture
every drop of water and used water to treat
and reuse. This is supported by a Smart
Water Management system that collects
critical data for monitoring, reporting and
decision making.
The solution can be scaled from a single
building to an estate, such as a residential,
industrial or mixed development estate. To
date, Ecosoftt’s solutions has been applied
in a range of residential, commercial and
industrial properties, including hotels,
office buildings, commercial laundries,
A smart urban farm like an urban hydroponics
farm can control for key crop growth factors,
including hydration, lighting, and nutrient
requirements. Using sensors to collect data,
operators can remotely control the facility’s
pumps, actuators, lights and other equipment
to make the appropriate changes to optimise
growth conditions.
Food waste management and reduction
represent another opportunity. The integration
of smart solutions enables audits and data

review to be conducted seamlessly.
Current technologies allow for the
accurate logging of food waste, based
on type and quantity. This allows
commercial kitchen operators to
access data for fine-tuning production
and tracking wasteful practices.
Any excess food waste can then be
converted to organic fertiliser for urban
farming, forming a symbiotic relation
between the two.
Fig 4: Ecosoftt’s
model for smart,
circular estates for
energy, food and
material.
CLOSING THE MATERIALS LOOP
Solid waste from buildings and
industries have conventionally been
left to municipal waste sorting stations,
incinerators or waste at energy
plants and landfills. None of these
are sustainable in supporting our
demand on natural resources.
Here, new technologies are offering
new ways to address this difficult
issue. Catalytic pyrolysis offers
a potential means to sustainably
reduce the accumulation of plastics
within landfills. Through this process,
recovery of valuable energy products
such as oil and gas can be achieved
as well. Recovered hydrocarbon gas
products can be recycled and put back
into the process, essentially creating
a net-zero energy system. A potential
drawback of using pyrolysis is the
need to pre-treat the plastic feed by
washing and shredding it, all of which
involves the additional consumption
of resources. However, with good
wastewater management solutions and
generation of energy on-site, these
drawbacks can be minimised.
Another option is having an on-site
incineration installation, allowing the
conversion of material inputs and
wastes into ash and heat. This reduces
the volume handled, allowing for more
efficient handling and management
of material waste as opposed to
conventional collection schemes.
CONCLUSION
These resource management
strategies demonstrate that there
is much room for us to move away
from the “once-through model” to a
more circular approach in buildings
and industries.
In many cases, the technologies are
already proven and viable, or will
become viable in the foreseeable
future. For other technologies,
there is scope for innovators and
facility owners to collaborate in
developing and test-bedding
initiatives. With the rising price of
resources and increasing attention
to environmental, social and
governance goals, there is now
considerable economic incentives
for players across the value chain
to embark on circular management
initiatives. We have been presented
with mankind’s greatest challenge,
as a result of our own doing. But
we are hopeful that we have the
ingenuity to solve this problem.
Charles Dickens’ famous
words may aptly describe the
circumstances that we are in: “It
was the worst of times, it was
the best of times, it was the age
of foolishness, it was the age of
wisdom.” May wisdom prevail and
the best of times continue.

UPCOMING SWA ACTIVITIES
Sg-IL Connects: Sustainable Water
Resources for the Future
Co-organised with Foreign Trade Administration,
Embassy of Israel, Singapore
9 Nov 2022, Webex
Sustainable development of water resources involves reducing
the usage of water and recycling of wastewater for different
purposes such as cleaning, manufacturing, and agricultural
irrigation in such a way that water demands of future generations
are not hampered. It also means water supply will remain
consistent, despite climate change impacts, such as a lack of
rainfall and drought, or too much rain and being flood resilient.
The Singapore Water Association and the Israel Trade &
Economic Mission in Singapore invites interested parties to join
the "Sustainable Water" tech exchange webinar, where one will
learn about the two ecosystems, and be exposed to the latest
water reduction, recycling and reuse technologies from both
Singapore and Israel.

TSURUMI’S AVANT MQC
slices away inefficient
wastewater treatment
The AVANT MQC achieves smoother wastewater processes without primary treatment
Choppers pumps deliver smooth and
reliable wastewater treatment.
In wastewater treatment facilities, solid
waste frequently accumulates inside the
collection tanks, where they may clog
impellers and the pipelines. The clogging
of the pump becomes a major problem that
can cause overflowing and jeopardise the
effectiveness of the entire system.
Bar screens and filtering grids might not
be an effective option for all applications
as they require continuous monitoring and
periodic removal of accumulated solid
wastes. During cleaning, the system might
require a shutdown with a specialised
technician, increasing operating expenses.
Moreover, the varied properties of waste,
which range from fibrous long solids
and plastic, renders pumps with grinder
mechanism and low free passage size
unsuitable. Furthermore, the grinder
hydraulics have limited flow rates and can
often take a long time to empty the tank to
the safety threshold.
Tsurumi’s AVANT MQC series consists of
chopper hydraulics designed to handle
wastewater without primary treatment. The
system’s main component is a steel knife
with a sharp edge that skims the channel
impeller’s blades to cut solid objects of
any size and composition. This prevents
both the impeller from clogging and the
accumulation of residue in the pipe, ensuring
the system runs smoothly and reliably.
The blades provided on the open channel
impeller are constructed out of hard cast iron,
which, at between 450 and 500HB, is more
durable than grey cast iron. The material is
comprised of several different components:
chromium, molybdenum, nickel, manganese,
copper, etc. AISI 431 stainless steel, which
has a carbon content of less than 0.22%
and a hardness of around 300HB, is used
for the knife, making it strong against shear
forces. Furthermore, the design of the cutting
mechanism allows easy replacement of the
blade for severely fouled wastewater handling.
As the chopper pumps are equipped with
MQ motors, IE3 standard motor efficiency
is achieved to reduce power consumption.
Furthermore, as with all of the MQ-series, dry
installation of chopper pump is possible with
the option of DRY version MQ motors. DRY
MQ motors are cooled with a mixture of water
and glycol that circulates in a special closedcircuit
inside a special design of the doublelayer
stainless steel jacket. An axial impeller
is also provided in the coolant chamber
for effective re-circulation of the coolant,
ensuring continuous heat exchange between
the motor and the external environment. Even
in a partially submerged or dry installation in
a high-temperature environment, continuous
operation in the S1 service class is guaranteed.
MQC Chopper pumps can be used for a
wide range of applications, from municipal
wastewater treatment plants and sewerage
pumping systems, to livestock farms and meat
processing industries. It can also be installed
in pulp and paper mill lifting systems, and in
wastewater pumping systems for textiles and
tanning industries.

YOKOGAWA
RELEASES NEW
The OpreX Magnetic Flowmeter CA Series,
as released by Yokogawa Electric Corporation.
magnetic flowmeter series
The Yokogawa Electric Corporation has
announced the release of the OpreX Magnetic
Flowmeter CA Series. This new product series
succeeds the ADMAG CA Series and is being
released as part of the OpreX Field
Instruments family. The products in this new
series are all capacitance-type magnetic
flowmeters that are capable of measuring
the flow of conductive fluids through a
measurement tube without the fluids coming
into contact with the device’s electrodes.
In addition to this non-wet electrode
construction, this series features new
functions that improve user-friendliness,
maintainability, and operational efficiency.
The new series is now available in most
major markets, such as Japan, South East
Asia, North and South America, Oceania,
the Middle East and Africa. It will also be
launched in Europe and China after qualifying
for CE marking and obtaining the relevant
certification for explosion-proof standards.
DEVELOPMENT BACKGROUND
In plants, inspection is required for
each instrument to maintain stable
operation and product quality, so the
efficiency of such inspections is an
ongoing issue for production sites. As
magnetic flowmeters have no structural
components that hinder the flow of
fluids and cause a loss in fluid pressure,
they are used in plants to measure
fluids with conductive properties. Large
chemical plants and other such facilities
can have hundreds of these instruments,
so it is important that the inspection
and replacement, as well as the
collection of the data from each of these
devices can be carried out efficiently.
In response to these needs, Yokogawa
has revamped the ADMAG CA line-up
of flowmeters and developed the OpreX
Magnetic Flowmeter CA Series. The
new series is equipped with features
to improve operational efficiency and
maintainability for release in a range
of regions. This will help reduce the
person-hours required for customer
instrument inspections and contribute to
improved plant operational efficiency.
FEATURES OF THE OPREX MAGNETIC
FLOWMETER CA SERIES
Capacitance-type magnetic flowmeters
utilise electrodes that are mounted
outside a ceramic measurement tube to
measure the electromotive force generated
by fluids passing through the tube,
reportedly minimising all direct contact
between the electrodes and the fluid. This
ensures a stable flow measurement of
fluids containing minerals that generate
electrical noise when they collide with an
electrode. Fluids used include latex for its
insulation properties, as well as fluids that
have low conductivity, such as deionised
water and mizuame, also known as millet
jelly. In addition to non-wet electrode
construction, the newly released OpreX
Magnetic Flowmeter CA Series has new
features such as support for Highway
Addressable Remote Transducer (HART)
communications protocol, a nine-language
user interface, device soundness analysis
functions to improve maintainability, and
easily replaceable measurement tubes to
suit a variety of purposes.

THE SMART RTU
dedicated to the
water industry
The Sofrel YDRIX
RTU, made by
Lacroix Environment
The Sofrel YDRIX is a remote terminal
unit (RTU) designed for water network
monitoring and automation in water
applications. The product is the
creation of Lacroix Environment, a
French-based technological company
specialising in creating smart products
for managing water and energy
networks.
The use of integrated input or output
(6DI/2AI and 4DO) and communication
interfaces (RS232/RS485, ethernet
and modem) make the product easier
to integrate into water applications.
The RTU’s compactness makes it
compatible for the following water
applications: pumping stations,
drilling stations, lifting stations and
water tanks. When needed, the
product’s modular architecture allows
users to add expansion modules
to fill requirements for wastewater
and drinking water treatment plant
applications.
The YDRIX RTU is also embedded
with water libraries, such as pumping
and lifting stations, to quicken
deployment and accelerate time to
market. The product natively integrates
a telecommunication modem to
allow usage on 2G, 3G or 4G telco
networks. This integrated modem
facilitates the deployment of the
system by having a single product to
deploy, instead of having an RTU with
an external modem. Maintenance
is also simplified through having a
single product to maintain and update.
YDRIX RTU is also compatible
with Sofrel dataloggers and allows
direct communication between both
products. This provides complete
dataloggers and RTU systems to
users.
COMMUNICATION WITH ALL
STANDARD SCADA SYSTEMS
YDRIX integrates a native
implementation of standards protocols.
This allows for inter-operability with the
transmission control protocol (TCP)/
internet protocol (IP) networks, as
well as to operator supervisors, by
using the standard DNP3 and IEC
60870-5-104 communication protocols
over TCP/IP networks. Integration
into existing networks is thus more
straightforward.
The product can also reportedly
interface directly to any supervisory
control and data acquisition
(SCADA) system, such as WinCC or
Wonderware, meaning that the RTU
can fit into a pre-existing telemetry and
SCADA network.
SECURE COMMUNICATION AND
INTEGRATED CYBERSECURITY
YDRIX RTUs are “full IP”, meaning
they can communicate via their 2G,
3G or 4G modems or their ethernet
links to the SCADA central station.
These multiple systems allow for
redundancy among the communication
media. In the event of failure on the
main telecommunications network, the
Sofrel YDRIX automatically switches
to secondary support and returns
to normal when the initial network
becomes operational again. Operators
can thus rely on this system to prevent
the loss of information and recover
network data in real time.
The Sofrel YDRIX can secure the
overall system with user management
implementation. This allows operators
to grant authorised access to the
product solely to approved users. The
user management system also allows
operators to provide different access
permissions, such as read-only,
configuration and administration.
The product is also embedded with
a VPN client. With this VPN client, it
can connect to a VPN server using,
for instance, Open-VPN protocols.
This connection allows for the data
exchanged between the two structures
to be fully encrypted, ensuring
infrastructure security.

cover the last metre between COOL-
FIT 2.0 and the cooling unit.
The COOL-FIT 2.0 Push System
now bridges the gap by extending
the product range with smaller
dimensions. Designed for
temperatures between 5-60°C,
it includes sizes from d16 to d32.
Based on the iFIT range from GF
Piping Systems, the COOL-FIT 2.0
Push System offers a plug-and-play
installation through mechanical
connections, bendable pipes, and
modular adapter technology.
The COOL-FIT 2.0
Push System offers
a plug-and-play
installation thanks
to mechanical
connections,
bendable pipes, and
modular adapter
technology
The COOL-FIT 2.0 from GF Piping
Systems was said to have changed
how people planned, installed and
operated cooling applications. The
pre-insulated plastic piping system
is corrosion- and condensationfree
and can be installed in cooling
applications in commercial and
residential construction, data centres,
or process cooling. With the addition
of the COOL-FIT 2.0 Push System,
it has become a complete solution:
additional dimensions cover the last
metre between the main pipeline and
fancoil or air handling unit, leading to
higher energy efficiency and a more
reliable operation.
Air conditioning (AC) technology is
becoming increasingly important.
The new COOL-FIT 2.0 Push System bridges
the gap between the main pipeline and the
cooling unit by extending the COOL-FIT range
with smaller piping dimensions
The number of air conditioning units
in buildings is estimated to reach 5-6
billion by 2050, due to climate change
and rising population numbers. At the
same time, high-tech industries rely on
AC for process cooling applications,
such as data centres or manufacturing.
As a result, the need to reduce CO2
and greenhouse gas emissions is
greater than ever.
GF Piping Systems aimed to address
this challenge by developing a
pre-insulated three-in-one piping
system for chilled water, including
pipes, fittings, valves, and tools.
This complete system has seen use
in comfort cooling and a range of
commercial and industrial applications.
Customers have previously relied on
pressed and welded metal systems or
post-insulated polyethylene pipes to
Made of lightweight materials,
COOL-FIT 2.0 is a corrosion- and
maintenance-free alternative to
metal piping systems. Furthermore,
these material properties mean that
the system can operate for 25 years
without interruption. Its three-in-one
design, consisting of pipe, insulation,
and robust jacket, combined with
efficient and easy jointing technology,
can result in a 50% faster installation
time than post-insulated metal pipes.
Due to pre-insulation and the use of
plastic, COOL-FIT 2.0 also minimises
pressure losses and has low thermal
conductivity, making the system 30%
more energy-efficient.
“We have already shown that plastic
piping systems are a long-lasting,
easy-to-install, and high-performing
solution for a wide range of cooling
applications,” said Kevin Blumberg,
senior business development
manager cooling at GF Piping
Systems. “Introducing the COOL-
FIT 2.0 Push System is an important
step forward; we can now bridge
the gap to the cooling unit for our
customers. COOL-FIT is a complete
solution for confident and safe
insulation that makes commercial
and industrial cooling more energyefficient.”
