Abstract

1377424 Ultra-filtration INDUSTRIELE ONDERNEMING WAVIN NV 18 Jan 1972 [18 Jan 1971] 2423/72 Heading B1X [Also in Division F2] A device for purifying liquids, particularly water, by means of reversed osmosis comprises an assembly consisting of an auxiliary supporting plastics tube which is provided with openings in its wall and which, on its inner side, is provided with a fibrous permeable layer on the inner side of which is disposed a membrane, while the auxiliary supporting plastics tube on its outer side is supported by a main supporting tube which at least on its inner side has discharge channels extending in a longitudinal direction. The plastics tube may be PVC: the permeable layer paper, glass or nylon fibres on which a cellulose-acetate membrane is deposited; the main supporting tube may also be of plastics. The channels in the main supporting tube may be longitudinal or helical grooves. A group of such devices may be connected in parallel between header plates and several such groups may be connected in series.
