Singapore's first water treatment plant to use ceramic membrane technology

Ceramic membrane technology will enable CCKWW to increase its operating efficiency

The water treatment plant at Choa Chu Kang will be the first in Singapore to use ceramic membrane technology to increase its operating efficiency.

When it becomes operational in 2018, the ceramic membrane plant at Choa Chu Kang Water Works (CCKWW) will be one of the largest in the world using the technology for water treatment. It will have a daily capacity of 40 million gallons per day (mgd).

The technology will enable CCKWW, which will undergo the upgrading later this year, to be energy efficient with a much smaller footprint and have a lower life cycle cost compared with existing membrane systems.

National water agency PUB will partner PWN Technologies (PWNT) on the use of PWNT’s membrane technology to upgrade part of the water treatment system at CCKWW. UGL (Singapore) will design and build the plant using the membrane system from PWNT and membranes supplied by Japan’s Metawater.

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.”

Since its introduction in Japan in 1998, ceramic membrane technology has been deployed in more than 117 plants in the country.
