Industrial used water treatment plant OK'ed for one-year demo

It will be the first plant of its kind in Singapore capable of treating 1M gallons of industrial used water per day, says PUB.

The demo plant could lead to more energy and cost savings in the treatment of industrial used water, added PUB, Singaporere's national water agency, which signed an agreement with Meiden Singapore (MSL) to establish the first Ceramic Membrane MBR Demonstration Plant in Singapore.

"MSL will also establish an R&D centre and assembly factory for ceramic membrane units in Singapore, as well as a facility for development, production and after-sales service in Asia. MSL will also be the regional Headquarter for water business in Asia," PUB said in a release.

"The demonstration plant will be sited at the Jurong Water Reclamation Plant in Singapore and construction is expected to complete by August 2013. The one year demonstration study will focus on process optimization. The plant will be capable of treating one million gallon (i.e. 4,550 cubic meters) of industrial used water per day," PUB said.

"The reclamation of high COD industrial used water has conventionally been considered difficult. This project aims to demonstrate the effectiveness of Meiden’s used water processing system by combining the use of the Upflow Anaerobic Sludge Blanket (UASB) technology and Meiden’s Ceramic Membrane MBR system in achieving energy savings and a consistent high-quality output of recycled water," it added.

"The use of UASB, a biological process, can remove COD efficiently while the Ceramic Membrane MBR, which has a longer lifespan than conventional membranes, can produce a stable water supply for recycling purposes. Together, they can potentially result in more energy and cost savings in the treatment of industrial used water," PUB explained further.
