Performance Improvement of Solar Still with and without Use of PCM

Abstract

Water problems are same in worldwide. Mainly it is faces by rural area peoples. Mostly drinking water is available from wells and rivers. Because of high population and industrialisation this water might be contaminated with harmful substances such as bacteria and therefore unsafe drinking water. Purification of water by solar is most useful and economic and safe solution. Solar still are mostly useful in rural and tribal area to provide clean water. Solar water still easy to construct, output depend on type of model. And it is operated by unskilled person easily no hard maintenance required and no operational cost and are also clean and safe process and no any type of pollution spread by this process. In this experimentation work comparison is to be made between with and without use of phase change material. It is observed that use of latent storage in solar still will increase water output.
