Abstract

1422725 Water purification SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 14 March 1973 [16 March 1972] 12179/73 Heading C1C In a process for water purification in which finely divided activated C is used, the C is regenerated by separating the C from the water as a concentrated suspension therein, processing this into granules which are regenerated (e.g. by heating in a stream of air and steam), the granules are then ground and the resultant finely divided activated C is recycled.
