Filtering impurities and bacteria from waste water often requires the use of polymer or ceramic membranes - but these often come at a high cost and require frequent cleaning with expensive chemicals. <\/p>\n
Now, a team from the Nanyang Technological University (NTU) in Singapore has come up with a self-cleaning membrane that is more cost-efficient. <\/p>\n
Announced at a media briefing on Thursday, this membrane is made from a patented titanium dioxide nanotechnology - the brainchild of Assoc Prof Darren Sun, from NTU's School of Civil and Environmental Engineering. <\/p>\n
\"With more of the world's population moving into urban cities and generating more waste water, there is a real need for cost-effective technology,\" Prof Sun said. <\/p>\n
Polymer membranes, for instance, need to be replaced every two or three years, but the NTU-made membrane is expected to last twice as long. <\/p>\n
The nano particles in the membrane also react to sunlight, helping them clean off the debris collected without the need for washing with chemicals like sodium hydroxide. <\/p>\n
