In India the difficulty of drinking water is becoming increasingly, due to the two factors; firstly that the population of the India has increased fast and secondly the standard of living of human being has increased. Only 1% of earth’s water is in a fresh, liquid form, and nearly all of this is polluted by diseases and toxic compounds. For this cause, purification of water is very important for drinking.
Keeping these things in mind, we have manufactured an experimental model which will convert the dirty water into pure clean water using non-conventional sources of energy (i.e. solar energy).In this paper, we have got two comparative experimental data first simple distillation system means without using any phase change material and second same distillation system using phase change material like paraffin wax. This paper presents a practical study of heat transfer enhancement of paraffin wax existing in solar distiller a form of two packets. The Experiment was performed different depth level of water in solar still like 10 litters, 15 litters and 20 litters. The practical tests conducted in Thatipur, Gwalior (M.P.) winter season at November and December 2015. The result show that the experiment performs with and without using paraffin material, with using paraffin material is more effective. It has increased distiller amount as well as distillation time.
