Zusammenfassung:A system for water treatment the system including at least one water treatment unit including at least one membrane and having a feed water inlet at a feed side of the at least one membrane and a permeate outlet at a permeate side of the at least one membrane and an intermittent cleaning control subsystem operative to provide intermittent cleaning of the at least one membrane by causing the permeate to pass through the at least one membrane from the permeate side to the feed side thereby dislodging foulants from the at least one membrane by at least one of at least one of narrowing and closing the permeate outlet thereby causing an increase in the pressure of the permeate at the permeate side of the at least one membrane and reducing the feed pressure by at least 5% without significantly increasing the permeate pressure.
