This allows the most efficient way to absorb the bounty of ocean water. Saltwater desalination is a prospect because a large number of arid areas adjoin or are close to the ocean coast. Thus, the ocean and seawater are raw materials for industrial use. There are now around 30 methods of desalinating seawater. All methods of transforming salt water into fresh water require more energy. Typically, electricity accounts for about half of the cost of desalination, with the other half going to maintenance and equipment depreciation. So, the cost of desalinated water mainly depends on the cost of electricity. (FWR, 2011) However, where there is a lack of fresh water and the conditions for desalination exist, the cost factor takes a back seat. In some areas, desalination is far more environmentally beneficial than water supply. Desalination of salt water is growing quite rapidly. Thus, every two or three years, the total capacity of the installations
