Abstract: An apparatus and a method use permeate to flush a reverse osmosis filter membrane in the same flow direction as when fluid is being filtered through the membrane. The apparatus includes a housing having a membrane positioned therein. The membrane has an interior surface and an exterior surface. The housing has an inlet port located outward of the exterior surface of the membrane and first and second outlet ports. The first outlet port is located outward of the exterior surface of the membrane and the second outlet port is located inward of the interior surface of the membrane. A first pump is used to route pressurized, untreated fluid from a fluid source through the membrane to produce permeate. A second pump is used to route permeate to a desired function while also routing some permeate at low pressure to the housing to flush the membrane.

Abstract: An apparatus and a method for using permeate to flush a reverse osmosis filter membrane in the same flow direction as when fluid is being filtered through the membrane is disclosed. The apparatus includes a housing having a membrane positioned therein. The housing has an inlet side and an outlet side. The membrane has an interior surface and an exterior surface. The housing has an inlet port located outward of the exterior surface of the membrane, at the inlet side of the housing, and a first outlet port and a second outlet port both located at the outlet side of the housing. The first outlet port is located outward of the exterior surface of the membrane and the second outlet port is located inward of the interior surface of the membrane. A first pump is used to route pressurized, untreated fluid from a fluid source through the membrane to produce permeate. A storage tank holds permeate until needed.
