A new technology from Panasonic, now allows water purification using sunlight

Drinking clean and purified water is a luxury in many parts of the world. And, providing safe drinking water is a challenge in many ways. While there are several ways of purifying water, most of them prove expensive, and thus unfordable. But, the new technology from Panasonic is going to help produce clean water with very little effort. Using sunlight and photocatalysts, this new technology turns polluted water to clean water in no time. This certainly is a huge breakthrough getting potable water to those who need it.

Panasonic's new technology can purify water using sunlight  Read more: Panasonic's new technology can purify water using sunlight | Inhabitat - Sustainable Design Innovation, Eco Architecture, Green Building This system of water purification is fairly simple, and works by binding titanium dioxide (Ti02) – which reacts with uv-light – to zeolite. Earlier, scientists have attempted to harness titanium dioxide for this purpose in the past, but because it is such a fine particle it disperses too quickly in water. The zeolite helps to solve that problem. When the Ti02 and the zeolite and agitated, the Ti02 separates, giving it a super quick reaction rate. After the water calms again, the Ti02 and zeolite re-bind, which means, that they can be removed easily from the water for re-use.

Even though this new technique by Panasonic works on small scale, but it has the potential to be used in a variety of different applications. Nonetheless, this purification system could be a real solution for people who constantly have to live in and around dirty and impure water.
