Abstract
1297650 Membrane module for reverse osmosis AQUA-CHEM Inc 2 Dec 1969 [6 Dec 1968] 58892/69 Heading B1X A reverse osmosis apparatus 10, e.g. for desalination, comprises at least two tubular semi permeable membranes 34, e.g. of cellulose acetate, separated from adjacent membranes by either interposed tubular porous sheets 32, e.g. of paper or porous plastics or by one such continuous sheet. Grooves 16, 24 of an impermeable casing 12 and core 20 support the membranes and sheets. Each groove 24 is bounded by ridges located between adjacent membranes and channels 28 in the core 20 communicate with the porous sheets 32 via these ridges to provide a liquid flow path to the core for the pure liquid permeating through the membranes. Alternatively the channels 28 may be omitted and the core be made of porous material. The membranes may be cast onto the inside of the porous sheets or extruded therewith so that only one layer of porous sheet separates adjacent membranes. The outer casing may be strengthened by resin impregnated fibre glass strands 14. In use, Figs. 3, 4 (not shown) the apparatus has end caps which in the case of parallel flow have conduits connecting each membrane to a common feed inlet and a common concentrate outlet, or in the case of serial flow have conduits connecting adjacent membranes. The serial and parallel flow conduits may be combined.
