"By replacing a defective membrane filter in time, the plant operator can avoid damaging downstream water treatment processes. It would also mean that individual failed filters can now be replaced as and when it is required, compared to the conventional standard procedure of replacing multiple filters at regular intervals," Dr Yeo added.
The technology is funded by the Environment & Water Industry Programme Office's (EWI) Tech Pioneer Scheme, and supported by the Singapore National Research Foundation under its Environmental & Water Technologies Strategic Research Programme. EWI was set up in 2006 to spearhead the growth of Singapore's water industry. Through funding promising research projects, the EWI aims to foster leading-edge technologies and create a thriving and vibrant research community in Singapore.
"The Membrane Integrity Sensor, a key component of the Memshield system, has the potential to provide effective monitoring of low pressure membrane systems without increasing cost of operation for water treatment plants. We welcome individuals and organisations to step forward with more of such exciting R&D ideas that will benefit Singapore's water eco-system and potentially the global water industry," said Mr Harry Seah, Chief Technology Officer, PUB, Singapore's national water agency and Director of Technology Development, EWI.
To be showcased at the upcoming Singapore International Water Week held from 1-5 July at Sands Expo & Convention Center, Marina Bay Sands, Memshield is now being tested by PUB, at the Bedok Waterworks and Chestnut Avenue Waterworks.
Two other large water companies in France and Australia have also recently purchased the system for trial.
A typical water treatment plant which processes 200,000 cubic meters of water daily will require about 10 to 12 Memshield units, with each costi
