Plants based on reverse osmosis technology

The reverse osmosis desalination plant consists of high pressure pumps, a power transmission device, and a reverse osmosis membrane. Before the seawater passes through the reverse osmosis membranes, it is pressurized by high pressure pumps at a pressure of between 55 and 85 bar, depending on the salinity and temperature of the water.
Osmosis membranes allow water molecules to pass through a semipermeable membrane and prevent the passage of other solutes.

The pressure difference on both sides of the membrane ranges from 1.5 to 2 bar, depending on the amount of water in the pressure vessel, and thanks to the energy conversion devices, the energy produced by the concentration difference can be reused. The pressure concentration is directed to the ERD power device, which transfers the energy to the water supply section 2.
