A Review on different Domestic Designs of Solar Stills

Abstract

The availability of safe, fresh and clean potable water is the major problem faced by most of the countries in the world. Many water purification technologies are developed out of which solar distillation or desalination is being most economical and sustainable technology under development. The solar stills provide a great relief to the remote areas where advanced purification technologies such as reverse osmosis, UV, electro dialysis cannot be used due to cost constraints. In last few decades there are number of solar still designs developed. This article reviews different solar still designs used at domestic level relative to each other. The solar stills are not commercialised or standardized due to their limited yields. However with the current research and improvements they can be successfully commercialised for future   domestic applications.
