Seawater reverse osmosis systems are a technological process used to make seawater suitable for drinking water or industrial use. These systems use the principle of osmosis to purify sea water from salt and other pollutants under high pressure.These systems generally consist of four main components: Pretreatment is a preliminary treatment to remove large particles and pollutants from seawater. This step may involve filtering the seawater, removing sediment and removing large particles such as sand and gravel.Reverse osmosis membranes This step involves passing seawater through a membrane layer under high pressure. These membranes pass through water molecules while holding back salt and other contaminants. In this way, cleaner and drinkable water is obtained. Pressurization system It is a system that provides high pressure to pump seawater into reverse osmosis membranes. This pressure helps water move past salt and other contaminants as it passes through the membranes. Final treatment It is done to improve the quality of the fresh water obtained. In this step, the pH level of the water can be regulated and the necessary minerals are added to make it compatible with the drinking water standard.Seawater reverse osmosis systems are frequently used in coastal areas, on ships and in island nations to provide drinking water.
