Reverse Osmosis Desalination Process. The core process of desalination is the Reverse Osmosis Process. It consists of a High pressure pump followed by an Energy Recovery device and the Reverse Osmosis Membranes.
This process is called chemiosmosis because the chemical ions move from an area of higher concentration to an area of lower concentration across a semipermeable membrane, similar to the movement of water molecules by osmosis. Word origin: chem- (chemical) + osmosis.
