Reverse osmosis
Reverse osmosis membrane separation process whereby a solvent is recovered from a solution. Permeability of the membrane is naturally very low since solutes are to be retained, and the normal osmotic pressure effect has to be overcome because the pressure required to cause the solvent to flow is high. To help the permeability, membranes are thin and it is necessary to support them well. They can be cast on porous tubes or as hollow fibers, and these forms are convenient for giving large areas as well as strong configurations. There is a constant flow across the membrane to prevent buildup of solid particles. The purified liquid is known as permeate and is almost always the desired product although proposals for using the concentrate, e.G., In fruit juices, have been investigated. See osmosis.
