1.FILTERING WATER WITH NANOTECHNOLOGY

Last year, 2014, Nano Sun of Singapore’s Nanyang Technological University developed a multi-functional water filtration membrane. This latest water filter technology uses titanium dioxide nanotechnology instead of the usual polymer-based water filtration membranes.
A young startup at Singapore’s Nanyang Technological University (NTU) has developed a multi-functional water filtration membrane. Its inventors hope it will render current membranes in the water industry obsolete. Traditional polymer-based water filtration membranes tend to end up clogged up with what they have filtered out.

2. PHOTO-CATALYTIC WATER PURIFICATION TECHNOLOGY

To solve such drinking-water issues worldwide, Panasonic has developed its own photo catalytic water purification technology. This technology uses photo catalysts and the UV rays from sunlight to detoxify polluted water* at high speeds, creating safe and drinkable water.
When photo catalysts are exposed to ultraviolet light, formed reactive oxygen purifies the toxic substances. However, TiO2, a kind of photo catalyst, comes in extremely fine particles and is troublesome to collect once dispersed in water. Methods of binding TiO2 to larger matter have hence been used, but they in turn suffered a loss of surface active site. Panasonic developed a way of binding TiO2to another particle, zeolite, which enables photocatalysts to maintain their inherent surface active site. Click here for full news.
