Solar water distillation

Abstract

In this research paper we studied water is the main source of sustaining living beings in earth. Nearly 70% of earth surface is covered with water. Water is available in different forms such as sea water, surface water, underground water, and atmospheric water. There is less amount of water only left on earth that is safe to drink without purification after 20-25 years. 99% of Earth water is in a solid state and other impure form and the remaining is in liquid form water on earth is contaminated with impurities and chemical substances. Therefore, it cannot be used for agriculture, industrial and human consumption. Due to water shortage has become one of the major global challenges, which is linked to population growth. Ground water and reservoirs are the available sources of fresh water to fulfil the needs of living beings. But these sources are not always useful due to dissolved impurities for this reason, purification of water supplies is extremely important. Everyone wants to find out the solution of above problem with the available sources of energy in order to achieve pure water Solar distillation is an effective method by which we can purify the water with the help of solar radiation. Distillation replicates the way nature makes rain. The sun's energy heats water to the point of evaporation. As the water evaporates, water vaporizes, condensing on the glass surface for collection. This process removes impurities such as salts and heavy metals as well as eliminates microbiological organisms. The end result is water cleaner than the purest rainwater. The Solar aqua still is a passive solar distiller that only needs sunshine to operate. There are no moving parts to wear out.
