Abstract: A system and method for a point of use filtration system with backwash is provided. The system includes a first filtration element, a tank, and a second filtration element positioned downstream from the tank. A first and second valve are each positioned downstream from the first filtration element. A first control line is coupled to a first control switch or a first permeate line and the first valve, and a second control line is coupled to the second control switch or a second permeate line and the second valve. When the point of use demands permeate water, the first and second pressure drops cause the first and second valves to open so water from the tank flows in a reverse direction to backwash the first filtration element and exit through the first and second valves to the drain, while water from the tank simultaneously flows through the second filtration element to the point of use.

Abstract: A water filtration system that includes a filter manifold having a rotatable cover is provided. A filter cartridge is provided that includes a sump having a filter head integrally secured to a first end and cap releasably secured to a second end. A locking mechanism extending from the cover locks into the filter manifold to position the cartridge in an “in-use” state. The filter cartridge further includes two offset cylindrical inlet and outlet members protruding from the filter head that are designed to engage corresponding inlet and outlets of the filter manifold through a horizontal engagement mechanism. A check valve is positioned within the filter manifold adjacent the inlet of the filter cartridge to control fluid flow through the water filtration system. The filter cartridge head includes fins upwardly extending therefrom that are configured to engage corresponding slots formed in a plurality of corrugated channels of the filter manifold.
