ABSTRACT:
A reverse osmosis element consists of a long tubular plastic base having a plurality of elongate parallel channels in its exterior surface. A monofilament strand is wrapped or extruded helically around the surface of the base, and a semipermeable membrane is formed, e.g. by casting or extrusion, around the wrapped tube. The tubes are mounted in a hollow cylindrical housing on a manifold; a passageway for purified water extends through the membrane, along the channels to the interior of each element, from the interior of each element through the manifold to a collection chamber, and to a purified water outlet.
