Reverse osmosis separation technology is used to remove dissolved impurities from water through the use of a semi-permeable membrane. RO technology involves the reversal of flow through a membrane from a high salinity, or concentrated solution to the high purity, or "permeate", stream on the opposite side of the membrane. Pressure is used as the driving force for the separation. The applied pressure (P) must be in excess of the osmotic pressure of the dissolved contaminants to allow flow across the membrane.
