Introduction to Reverse Osmosis Seawater

Reverse osmosis seawater desalination is a process that uses a semi - permeable membrane to remove salts and other impurities from seawater, producing fresh water. This technology has become increasingly important in regions facing water scarcity, as it provides a reliable source of clean water. The reverse osmosis process works by applying pressure to seawater on one side of the membrane, forcing water molecules through while leaving behind salts, minerals, and other contaminants.
