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. 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 works on the principle of photocatalytic disinfection of water over photocatalyst using solar light.
