Effect of Various Parameters on Augmentation of Distillate Output of Solar Still: A Review

Abstract

A Simple device which is used to obtain fresh water from saline water with the use of solar desalination process is known as solar still. The simple solar still give an output of 2.5 to 5 litres per 1m2 area per day during bright sunshine hours. Hence various investigation has been done by scientists and researcher to improve the performance of solar still by inspecting various design parameters(water depth, condensing cover material, its thickness and inclination, type of solar still), climatic parameters(wind velocity, ambient temperature, solar radiation), operational parameters (salinity of water) which affect the production rate of solar still. In this review paper an attempt has been made to evaluate the effect of different design, climatic & operational parameters that affect the performance of solar still.
