PWNT has been assigned to build a 180 MLD CeraMac® water treatment plant at Choa Chu Kang Waterworks (CCKWW) for PUB, Singapore’s National Water Agency. This plant will be operational in 2018 and will be one of the largest ceramic membrane plants for drinking water treatment in the world.
UGL (Singapore) Pte Ltd will design and build the plant, with the membrane system from PWNT and membranes supplied by Japanese ceramic membrane specialist METAWATER.
This full-scale plant comes after a rigorous 18-month trial of PWNT’s CeraMac® demonstration plant was conducted from September 2011 to validate the efficiency and reliability of its ceramic membranes in water treatment.
The results exceeded all expectations. The daily capacity grew from 1.2 million liters per day to 3 million liters per day because of the combination of CeraMac® with ozone.
The demo plant was made possible with a grant from the Technology Pioneer Scheme under the Environment & Water Industry Program Office (EWI).
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 solid 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.”
Ceramic membrane technology has already been validated in Japan, with more than 117 plants at present (137 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.
