PUB selects PWNT ceramic membrane technology to upgrade Choa Chu Kang water works, Singapore

Posted on 30 October 2015

dws-pwn-pub-cctww-aerial-view2-770pxSingapore water utility PUB has selected CeraMac membrane technology of PWN Technologies to upgrade part of its water treatment plant Choa Chu Kang later this year.

This full-scale plant comes after a rigorous 18-month trial of PWNT’s CeraMac demonstration plant to validate the efficiency and reliability of its ceramic membranes in water treatment.

Singapore’s Choa Chu Kang water works (CCKWW) will become the first waterworks in Singapore to use ceramic membrane technology to increase the plant’s operating efficiency and reliability.

CeraMac technology was successfully introduced for the first time at the Andijk III water treatment plant, the Netherlands in May 2014.

 PWNT developed a special high pressure vessel that contains the ceramic membranes. The vessel cleans the membranes fully automatic.

Lower life cycle costs
Ceramic membrane technology is one of the latest technological breakthroughs in membrane technology. It is energy efficient, with a much smaller footprint. Its life cycle cost is also expected to be lower compared with existing membrane systems.

National water agency PUB will collaborate with PWN Technologies (PWNT) to employ the use of PWNT’s CeraMac membrane technology.

UGL (Singapore) Pte Ltd will design and build the CeraMac system at CCKWW, with the membrane system from PWN Technologies and membranes supplied by Japanese ceramic membrane specialist Metawater.

The new CeraMac plant at CCKWW will have a daily capacity of 40 million gallons per day (mgd) and will be operational in 2018. Upon completion, the plant at CCKWW will be one of the largest ceramic membrane plants for drinking water treatment in the world.

Satisfying test results
Mr Harry Seah, PUB’s Chief Technology Officer said, "PUB is always on the lookout for more innovative and cost-effective ways of treating and producing water. We have been studying and testing the merits of ceramic membrane technology for a few years now, and we are satisfied with the results. Both polymeric and ceramic membranes can now be considered in our other waterworks when they are due for upgrading."

Jonathan Clement, CEO of PWN Technologies said, "We are proud to be a partner for this seminal project which serves as a powerful statement of PUB’s commitment to innovation in water treatment. Being chosen is also a validation of PWN Technologies’ commitment to developing and implementing sustainable, cost-effective water treatment systems for greater water security."

UGL CEO Ross Taylor said, "UGL in partnership with PWNT are pleased to be a part of the upgrade of Choa Chu Kang Water Works in Singapore. UGL has a solide track record in the water industry in Singapore dating back to the late 1960’s and we look forward to working with PUB and PWNT on the successful delivery of this innovative project."

Proven technology
Ceramic membrane technology has already been validated in Japan, with more than 117 plants at present (and 137 plants worldwide) utilising ceramic membranes similar to those that will be installed at CCKWW.

The first of these membranes were first installed as early as in 1998. There have been more than 17 years of continuous operation with no known membrane breaks, replacements or membrane-related shutdowns.
