Domestic Water Purification Device Based On Photocatalysis Using Solar Light
|
In a large number of underdeveloped and developing countries, there is scarcity of safe drinking water. People are forced to drink contaminated water infested with disease causing bacteria, which causes many water born diseases. Various methods like chlorination, ozonation, boiling and irradiation by UV light are used to purify water. However these methods require chemicals, fuel, and electricity, which are not available in remote undeveloped areas. A “domestic water purification device” is designed on photocatalytic disinfection of water using non-toxic, reusable photocatalyst and solar light. The device does not require electricity, chemical and high pressure tap water.
APPLICATION The device is meant for purification of drinking water with respect to suspended particles, dissolved organics and bacteria. The device purifies water in batch mode. The device of 60 cm x 65 cm x 10 cm size can disinfect ~ 15 liters of drinking water daily using solar light.
