challenging waters such as high turbidity and
harmful algae blooms, in a compact footprint.”

In South East Asia, NSW has conducted
dozens of pilots with industrial partners,
which have led to over 100 installations,
according to the CCO. “We are working
with Maynilad Water in the Philippines to
improve the quality of drinking water in
metro Manila, cultivating relationships in
our focus regions whose water sources
present substantial treatment challenges,”
Hollen said. Another example, he added,
is a NSW partnership with electric power
generation company ACWA Power to
develop a pre-treatment solution for
seawater desalination in the Middle East,
which was piloted at the Barka desalination
plant in Oman.

In light of climate change and increasing
global water stresses, Hollen said that
these impacts are already threatening the
security of water supplies around the world,
whether through increased frequency
of algal blooms in warming climates
or heightened severity of droughts. In
response, authorities in some regions have
been implementing strict requirements
on the quality of discharged wastewater,
mandating zero liquid discharge (ZLD)
and reuse for certain applications in order
to safeguard water resources. “Looking
ahead, we see water scarcity escalating
while resource quality continues to decline,
making treatment all the more challenging,”
the CCO said.
To tackle this, Hollen said that the industry
must continue to innovate and prioritise
adaptive solutions to ensure water security.
At NSW, its ceramic membrane technology
is suited for difficult-to-treat waters across
a range of applications, including seawater
desalination, variable surface waters, and
challenging industrial wastewater. He said,
“We accomplish this through a combination

Additionally, the threat of micropollutants and
contaminants of emerging concerns, such as
per- and polyfluoroalkyl substances (PFAS) is
still present. In alignment of its goal to provide
product solutions that commit to protecting
the environment, NSW has complied with
applicable environmental regulations. “We
have conducted in-depth due diligence
on our supply chain and — based on our
production knowledge and declarations
collected from our suppliers — our products
do not contain any intentionally-added PFAS
chemicals,”
Hollen added.
With this enabling technology for water reuse
in both municipal and industrial applications,
NSW plays a role in resilient water supply.
“The robustness of our membrane provides
operational reliability, ensuring quality
water in the face of evolving challenges
presented by climatic shifts,” the CCO said,
“We strive to develop solutions that tackle
today’s concerns [and] are well-positioned to
address these future challenges.”
