Purification

Sun cloth and wind purification tank

The Sun Cloth and Wind purification tank is a very simple and affordable way of treating water. A lot of people exposed to unclean water in Africa have limited monetary resources. Therefore people can take advantage of the Sun Cloth and Wind purification tank that makes efficient use of two free abundant resources in Africa which are sunlight and wind energy. The dark plastic container mounted on a roof stand is an efficient absorber of sunlight. The sun’s energy in conjunction with the dark container allows the heating of the water which kills dangerous contaminants in unclean water. The wind powered swirl allows the heated water to circulate in the tank allowing residue to be deposited in washable cloth pockets on the sides of the container. The Sun Wind Cloth purification tank produces at least 120 litres of water in 8 hours of sunlight.
