Abstract

1,251,825. Reverse osmosis. AQUA-CHEM. Inc. 22 Oct., 1968 [25 Oct., 1967; 20 March, 1968], No. 50188/68. Heading B1X. A membrane structure suitable for reverse osmosis comprises a porous tube 11 of semi rigid material with an inner membrane coating 12 which is semi permeable. The tubes have an impermeable coating 14 at the ends. Tube 11 may be of paper or porous plastics. A reverse osmosis apparatus (Fig. 2) comprises a plurality of rigid tubes 16 each of which supports a membrane structure as above. The ends of tubes 16 are supported in bores 18 of header 20, each bore 18 terminating in an annular groove 22 which serves to collect product water for removal by tube 58. Water to be treated in channel 30 is prevented from reaching grooves 22 by O-ring seals 56.
