SOLAR DESALINATION BY USING PHASE CHANGING

Civil Engineering

Water is the most important element for sustaining life on earth. There is an important need for clean, pure drinking water in many developing countries. There are many coastal locations where seawater is abundant but portable water is not available. Often Water sources are brackish which contain dissolved salts or contain harmful bacteria. So purification of water is very important. For this purpose, a plant which can convert brackish water into portable water by using solar energy has been proposed and analyzed. A solar still has been developed for purifying water. It is simple and effective method to get purified water in a cost effective manner. Solar still effectively eliminate all water borne pathogens, salts, and heavy metals. This benefits the users by reducing health problems associated with water-borne diseases. The TDS ,pH, Hardness and density of water samples are tested before and after the distillation. Solar desalination by using phase changing material this process utilizes minimum amount of energy to produce potable water and this process is completely ecofriendly it also utilizes minimum area for installation.
