ABSTRACT:
A reverse osmosis system including a reverse osmosis filter with a reverse osmosis membrane and having an inlet port coupled to a source of feed water under predetermined pressure via a feed water inlet conduit, a product water outlet port for filtered outlet product water, and a brine outlet port for brine. A pump coupled into the feed water inlet conduit between the source of feed water and the inlet port of the filter and driven by the feed water under pressure. The pump increases the pressure of the feed water so that the reverse osmosis filter receives feed water at an increased pressure.
