What is required in the Reverse Osmosis Desalination process?

In the Reverse Osmosis Desalination process, seawater is forced through a semi-permeable membrane. This membrane allows water molecules to pass through while blocking the majority of dissolved salts and contaminants. The pressure applied to seawater enables the separation of fresh water from the saline water, effectively purifying it for use. This method is efficient and widely used for desalination because it consumes less energy compared to thermal processes that rely on boiling.

The process utilizes the principles of osmotic pressure, where the natural tendency of water to move from an area of low solute concentration to an area of high solute concentration is reversed by applying pressure. As a result, this method yields fresh water that can be collected and stored for various applications, particularly in areas where freshwater resources are scarce.
