Abstract

1,250,482. Reverse osmosis. MARSHALL SONS & CO. Ltd. 18 March, 1969 [19 March, 1968], No. 13190/68. Heading B1X. In a method of reverse osmosis a high pressure pump 1 draws feed solution from a tank 2 and pressurises it in a closed loop comprising a circulation pump 3, a reverse osmosis separation cell 4 and a delay line 5. The cell 4 includes a plurality of series-connected or series/parallel-connected tubular membranes, and desalinated water is collected therefrom via outlet 7. Delay line 5 is initially full of feed solution and serves to delay the reject brine issuing from 4 from being reissued, via 3, back to 4, the size of the delay line reservoir being considerably greater than the volume of the remainder of the loop so as to prolong the delay. A resilient plug of plastics material may be inserted into each tubular membrane; on reversal of the direction of flow in the closed loop the plug is swept along the membrane and cleans it surface.
