Reverse Osmosis Plants

Fluid Systems provide Reverse Osmosis Plants which are based on the reverse osmosis process to clean impure water. Reverse osmosis is the process of forcing a solvent from a region of high solute concentration through a membrane to a region of low solute concentration by applying a pressure in excess of the osmotic pressure. As Reverse Osmosis does not occur naturally, it must be created by applying pressure to the high solids water in order to force it through the membrane, with pressures from 8 - 14 bar for fresh and brackish water, and 40 - 70 bar for seawater, which has around 24 bar (350 psi) natural osmotic pressure which must be overcome. The membranes used for reverse osmosis have a dense polymer barrier layer in which separation takes place.
