ABSTRACT:
An element for a reverse osmosis water purification cartridge consists of a long rigid plastic tube having peripheral V-shaped grooves along its length. A nylon monofilament is helically wrapped along the length of the element with wrap spacings of about 1/3-2/3 of the fiber diameter. The element is formed by placing liquid membrane-forming material on the wrapped tube; the membrane intrudes 1-2 mils between the adjacent wraps of monofilament.
