Water is an essential part of all living creature – human, Animals, plants etc. in olden days humans are depend on revers and ponds for fresh waters, but as industrialization goes on they are no more drinkable and fresh. So getting fresh water is a challenging job now a days in developing countries. As population is going on increasing, need for fresh water is keeps on increasing day by day. The available water on earth is limited to 79%, out of which only 2% water is directly available [1], from which only 0.36% is drinkable water [2]. Ocean is the main source of water but it contains highly salinity, so it need to first desalinate before use. There are many techniques to convert brackish water in to potable water [3].
Other methods for desalinations of Thermal Technologies like Multi Stage Flash (MSF), Vapour Compression (VC), Multi Effect Distillation (MED) and Membrane Technologies includes Microfiltration (MF), Ultrafiltration (UF), Nano filtration (NF) and Reverse Osmosis (RO) are costly and consumes conventional energy. Among them, MSF, MED and RO are commercially applied in large capacities in cities and always have high efficiencies based on electrical power consumption. However, these technologies are not suitable for remote villages, arid area and small islands [16].
Solar Distillation shows most attractive, simple and almost freely available technique among all other purification methods used at small scale use where solar energy is easily available. According to…
