Experimental Investigation for Drinking Water Production through Double Slope Solar Still

Drinking water supply will become a great challenge for whole world in the new era, because pure drinking water is a primary component for life & good health and it is integral part of our life. It may cause of spreading of diseases, if it in-hygienic or contaminated or improperly handled and stored. A lot of research is going on for the development of sustainable and cost effective technology to produce the drinking water, which will be free from harmful impurities. Suspended solids can be removed easily but arsenic, lead, chromium and excess fluoride contents are few major problems in sustainable supply of drinking water. So to provide the pure drinking water to everyone is becoming a challenging task. For getting pure water, electro dialysis, reverse osmosis and solar distillation etc can be used. Although every technology need the energy input to operate the purification device but reverse osmosis and electro-dialysis are intensive energy techniques while solar distillation is an attractive process to produce drinking water using cost-free solar energy. In this paper the experimental investigation of the fabricated double slope solar still has been presented.
