Abstract

Water is one of the essential resources in the world. Without water, the world cannot survive. Earth is covered by 71% water and 2.5 % coverd by freshwater. Out of 7 billion peoples, only 1.2 billion peoples are getting fresh water for drinking. The scarcity of water exerts strong effects around the world. The world is working to develop appropriate, cost-effective methods to provide high purified water for drinking purposes. Water contains suspended particles, micro-organisms, bacteria, organic and inorganic compounds as impurities. For purification, lots of methods are available which are widely used all around the world. This research is based on the research and development of water treatment plants which is cost- effective and provides safe drinking water for household purposes. Solar de-salination is one of the best energy efficient methods used for water treatment. In this process, solar energy is utilized to purify saline water. Minerals and salts were quickly removed as a brine solution and vapors condensed and collected to get the product. The energy requirement is low as compare to other methods. The construction of the plant was simple and cheap. This process removes 99.5 % of salts from the water. This research is successful in achieving the objectives and goals of getting potable water that meets the standards of WHO. This research also focuses on a large scale for water treatment as it is cost-effective and can reduce the shortage of freshwater around the world.
