ABSTRACT:
A reverse osmosis water purification module has an enclosed cylindrical housing in which at least twelve purification elements are mounted in a uniform, spaced parallel fashion. Each element consists of a long flat member having a thermoplastic sheet backing formed into a slightly curved cross section and having a semi-permeable membrane disposed thereon. The backing has three-dimensional porosity for purified water such that water passing through the membrane portion of the element travels along the backing member to an end. The ends of the module are mounted in a collection manifold which is sealed off from the remainder of the housing interior. A method of manufacturing the elements continuously is also provided wherein a continuous length of flexible backing material is fed sequentially through a heater, a forming die to impart a curved cross-section to the backing material, an extruder wherein membrane forming fluid is extruded around the periphery of the backing, a chill bath and a heating bath. After passing through the various process steps, the continuous length of material is cut into elements of desired lengths.
