| REVERSE
OSMOSIS |
In simple terms, reverse osmosis is the process of pushing a solution through a filter that traps the solute on one side and allows
the pure solvent to be obtained from the other side. More formally, it 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.
The membrane here is semipermeable, meaning it allows the passage of solvent but not of solute.
The membranes used for reverse osmosis have no pores, the separation takes place in a dense polymer layer of only microscopic thickness.
In most cases the membrane is designed to only allow water to pass through. The water goes into solution in the polymer of which the
membrane is manufactured, and crosses it by diffusion. This process requires that a high pressure be exerted on the high concentration
side of the membrane, usually 5 MPa - 20 MPa (50 bar - 200 bar). |
