Abstract: Distillation is one of the processes that can be used for water purification. This requires an energy input, as heat. Solar radiation can be the source of energy as heat for this purpose. In this processes, water is evaporated, thus separating water vapour from dissolved matter, which is further condensed as pure water. Solar distillation is a promising alternative that can partially support the human needs for fresh water with an environment-friendly energy source. At 3 cm water depth evaporation rate was higher and hence distillate yield was found more of about 11 liters in winter. Increased salt concentration would result decrease in distillate yield. The distillate yield in lower basin was found to be maximum as the additional thermal energy was provided. Water quality analysis was carried out, it revealed that the total dissolved solids and electrical conductivity was significantly reduced after distillation and it was within the limits of WHO and BIS standards.
