  • Reverse osmosis (“RO”) membrane system incorporating function of flow channel spacer
    Patent number: 6632357
    Abstract: A permeable membrane system (10) for the separation of fluid components includes a laminated composition (12) having two sheets (14 and 16) formed from a polymer and positioned adjacent one another to form a fluid passage (18) therebetween. The outside surfaces (20 and 22) of the sheets (14 and 16) are permeable to allow fluid flow from the outside surface (20 and 22) to the fluid passage (18).
