Abstract

1398112 Ultrafiltration CALGON CORP 16 June 1972 [16 June 1971] 14341/74 Divided out of 1398111 Heading B1X A method of treating a reverse osmosis of ultrafiltration system containing a permanent membrane to prevent fouling by interfering substances in contact therewith comprises depositing upon the memibrane a layer of a precoat composition comprising finely divided absorbent clay and activated carbon. The memibrane may be of cellulose acetate cast in a porous surface which may be tubular, fibreglass reinforced, spiral wound or flat. The system may be used for sewage treatment.
