Abstract
1320429 Reverse osmosis process ISRAEL PRIME MINISTER'S OFFICE 26 Nov 1971 [10 Dec 1970] 54984/71 Heading B1X A reverse osmosis process for concentrating a feed solution comprises pumping the feed solution along one side (the high pressure side) of a permselective membrane or of each of a plurality of membranes, diverting part of the more concentrated solution so produced from the product stream and causing it to flow along the other (low pressure) side of the membrane in countercurrent to the flow along the high pressure side, withdrawing as product the undiverted portion of the more concentrated solution and separately withdrawing a diluted solution emerging from the low pressure side. In the apparatus shown, a stainless steel body portion 40 encloses self-supporting capillary membranes 46 with their ends potted in epoxy resin. A feed brine is introduced at 43 and the brine concentrate product is removed at 44. Part of the brine product stream is diverted into opening 45 to flow through the membrane capillaries to outlet 47. The process may be used in the production of highly concentrated solutions from reject brines of brackish water desalination plants (21-in Fig. 3 not shown) and in the concentration of rejected digester liquor from pulping processes including sulfite and sulfate processes. There is also reference to juice concentration and concentration of heat-sensitive materials.
