Unlike conventional filtration which can be maintenance-intensive, costly, and environmentally unfriendly, membrane-separation technology employs crossflow filtration where captured impurities on the membrane are constantly swept away by the concentrate stream. Thus the membrane surface is continuously cleaned, prolonging the life of the membrane and reducing maintenance costs.
In residential applications, RO membranes are used to purify varying qualities of saline water. In a common application, the appropriate RO membrane element is housed inside a pressure vessel that accepts inflowing, pressurized saline feedwater. Crossflow filtration across the membrane then divides the flow into two outflow streams: the cleansed permeate feed and the concentrate or reject stream.
Compatible with the Pentek RO-300, American Plumber WRO-3000, and the Culligan RO-3000.
