Review on Water Desalination using Renewable Solar Energy

The availability of drinking water is the very important for all. Plenty of water sources are available on the earth but only 1% of the Earth's water is in a fresh, liquid state, and nearly all of this is polluted by both pathogens and toxic chemicals. Though there are many physical and chemical processes like reverse osmosis, electro dialysis, multi effect desalination to treat sea water, solar distillation is chosen due to its economic viability. Combining renewable solar energy and desalination would generate a sustainable source of fresh water as well as energy. This combination is highly valued as it limits and reduce air pollution emissions and greenhouse gases generated by the combustion of fossil fuels. So, we can say that solar distillation seems to be a promising method and find an alternate way to produce fresh water. Several solar stills deigns have been proposed and many have them found significant applications.
