Abstract
A fluid purification system is disclosed comprising a pressure vessel containing a plurality of spiral wrap membrane elements. The spiral wrap membrane elements are placed in parallel within the pressure vessel to purify an efficient amount of fluid for a given diameter fluid purification apparatus. The spiral wrap membrane elements have product fluid passageways of short length to insure a low pressure drop in the passageways.
Claims24
An apparatus for purifying fluids, comprising:
- a cylindrical housing means;
- a plurality of convoluted spiral wrap membrane elements contained in said housing and adapted to receive feed fluids under pressure, said elements acting to separate purified product fluids from said feed fluids, said feed fluids passing axially through said housing,
- said convoluted spiral wrap membrane elements having feed fluid passageway means and product fluid passageway means, wherein said product fluid passageway means are of short lengths so that only a low pressure drop occurs in the product fluid passageway,
- said convoluted spiral wrap membrane elements being arranged in parallel in a bundle within said housing to achieve efficient production of purified fluid for a given diameter housing.
