Detailed explanation-1: -Desalination is considered as a drought-proof water source, since it does not depend on river flows, reservoir levels, or climate change. Desalination may be an option to alleviate scarcity in industry and for coastal cities.
Detailed explanation-2: -Desalination is the process of extracting salt from saline water to make it drinkable. There are two main types of desalination. In the first – called thermal desalination – heat is used. This produces water vapour that condenses on pipes into fresh water.
Detailed explanation-3: -The problem is that the desalination of water requires a lot of energy. Salt dissolves very easily in water, forming strong chemical bonds, and those bonds are difficult to break. Energy and the technology to desalinate water are both expensive, and this means that desalinating water can be pretty costly.
