Panasonic’s Photocatalytic Water Purification Creates Drinkable Water

By -

Clean drinking water issues affect the world, especially third world countries that don’t have the proper technology to purify water.  Panasonic has developed its own photocatalytic water purification technology.

This technology uses photocatalysts and UV rays from sunlight to detoxify polluted water at high speeds, creating safe and drinkable water.  The project was unveiled at Tokyo’s Eco-Product 2013 and aims to be used by small rural communities.  The Japanese company Panasonic, which developed the new technology, has found a way to bind titanium oxide to another particle, zeolite.  If the water is left still, it will cause the titanium oxide to bind to zeolite again, making it easy ot separate and recover the photocatalysts from the water so they can be used again later.

The initial step uses the synthesis of photcatalysts when they are exposed to ultraviolet light, to for reactive oxygen to purify harmful substances.  The next and final stage disperses photocatalytic materials as the particles become agitated and TiO2 is released from the zeolite into the liquid, which makes it easy to separate and recover the reaction instigators from the liquid.

Panasonic said it is working to lower costs and maintenance requirements with the water purification systems and aims to make this technology available right across India and other emerging nations.  Panasonic is working with a number of institutions in India to test the product and its capabilities.
