Abstract
A method is provided for converting feedwater to fresh water utilizing existing water pressures and high flow rates. At least one reverse osmosis unit is disposed in a feedwater supply conduit. Feedwater is conveyed through the supply conduit and the reverse osmosis unit at a pressure that exceeds the osmotic pressure for solids dissolved in the feedwater. A first stream of fresh water is withdrawn from the reverse osmosis unit as permeate, and a second stream is withdrawn therefrom as effluent. The effluent is returned to, or continues to flow in, the supply conduit downstream of the reverse osmosis unit.
