Faculty of Mechanical Engineering Theoretical and experimental Investigation to improve the Performance of passive solar stills

Abstract

Scarcity of water is found in major parts of the world which must be newlineovercome for the betterment of the society Life without pure water is newlineimpossible because of its need in each and every activity of the society At the newlinesame time major water bodies are getting polluted which reduces the newlineavailability of pure water Also the major water sources are too salty that they newlinecannot be used for drinking purposes Desalinating the saline water and newlinepollutant removal may reduce water scarcity Conventional desalination newlinetechniques possess many disadvantages hence utilization of solar energy for newlinepurification is the right choice newlineIn South India Kovilpatti where the research was carried out has newlinebore wells which are heavily loaded with salt They exceed the limit for newlinedrinking This work concentrates on constructing economically feasible solar newlinestills Two single and double basin double slope steel and glass solar stills newlinewere made with 063m2 and 081m2 basin area and two single basin single newlineslope steel still with 025m2 basin area were also fabricated newline newline
