A Review to Increase the Performance of Solar Still Make It Multi Layer Absorber

Abstract

Water is the basic need to sustaining life on the earth for human. With the passage of time due to technical usage and their waste disposal along with ignorance of human being caused water pollution, which led the world towards water scarcity. To resolve t his problem Solar Distillation is one of the best Techniques from available another techniques. But, due to its lower productivity it cannot be commercial in the market. So that Lots of work can be done to improve the solar still efficiency or productivity. With the help of past research work we can conclude that if we are using multi layer absorber type solar still than its productivity will going to be increased and reflective radiation losses are covered by this one.
