Reverse Osmosis (RO) is a separation process that uses pressure to force a solution though a membrance that retains the solute on one side and allows the pure solvent to pass to the other side. More formally, it is the process of forcing a solvent from a region of high solute concentration though a membrane to a region of low solute concentration by applying a presssure in excess of the osmotic pressure. This is the reverse of the normal osmosis process, which is the natural movement of solvent from an area of low solute concentration, through a membrane, to an area og high solute concentration when no external pressure is applied. The membrane here is semipermeable it allows the passage of solvent but not of solute. The membranes used for reverse osmosis have a dense barrier layer in the polymer matrix where most separation occurs. In most cases the membrane is designed to allow only water to pass through this dense layer while preventing the passsage of solutes ( such as salt ions). This process requires that a high pressure be exerted on the high concentration side of the membrance, usually 2-17 bar ( 30-250 psi) for fresh and brackish water, and 40-70 bar ( 600-1000 psi) for seawater, which has around 24 bar ( 350 pai ) natural osmotic pressure which must be overcome.
