Reverse Osmosis Desalination or seawater reverse osmosis, or simply "RO" or "ROD," is a process that removes large molecules and ions - typically from seawater or ocean water, by the application of pressure to the sea water (or ocean water) when it is on one side of a selective "membrane" or filter. There are many benefits of reverse osmosis desalination, including: Cleansing drinking water. The leading process for desalination in terms of installed capacity and yearly growth is reverse osmosis (RO) (Fritzmann and others, 2007). In April 2005, Western Australia's Water Corporation chose SUEZ to design, build and operate Perth's first seawater desalination plant using reverse osmosis technology, the largest such plant in the southern hemisphere at the time. In this process sea water is forced against semi-permeable membranes under pressure in a continuous flow condition. The end goal of a desalination process is the removal of the salts present in seawater which are concentrated at about 3 to 3.5 percent. Water desalination process by reverse osmosis. of Commerce, Wash., D.C., U.S.). Designed to convert seawater to drinking water, these desalination systems use high quality SWRO reverse osmosis seawater desalination membranes. The combination of economic and demographic growth in particular has led to over-abstraction of . Desalination is a process that takes away mineral components from saline water. The costs can be high The maintenance of desalination plants can be really expensive since the machines and the equipment they use cost between $3000 million to about $3 . Reverse osmosis desalination is a process that removes salt from water by creating a barrier between the water and the salt particles. However, reverse osmosis desalination uses huge amounts of energy to overcome the process of natural osmosis and annihilate large particles from seawater through a membrane. . Sea water desalination is a process that separates saline water into two major components, the low dissolved salts concentration water stream (fresh or potable water) and the . For seawater feeds the energy requirement is high at 12 kWh/m 3 if there is no energy recovery, and 4 kWh/m 3 if there is energy recovery [19].
