Hello Imran,

Check-out a solar purifier called Waterward which uses glass panels where the water passes through a series of cascading trays, the sun shines through the glass into the water. The sun’s radiated heat rays are partially absorbed by the water and then more completely by the black specialist plastic panel of cells. The heat is then conducted to the water which vaporises and condenses on the underside surface of the glass and then runs down into the purified water collection channel.

Working at an ambient temperature between 35°C and 40°C, the water within the Waterward is heated to more than 85°C. This pasteurizing effect partially kills bacteria and pathogens dramatically reducing the risk of water borne diseases. Prolonged exposure to the sun’s ultra violet light simultaneously transmitted by the special glass cover completes the germ killing process Their website is http://www.sunsurewater.com/.

I do not own the company, nor work for it. I just liked the simplicity and effectiveness of the idea.

Regards,
