Abstract

1433666 Treating water ASAHI KASEI KOGYO KK 28 Feb 1974 [3 March 1973] 9138/74 Heading C1C [Also in Division B1] A fixed-bed solid-fluid contacting process comprises passing a fluid to be treated in one direction through a treatment zone packed with active solid particles, and regenerating the solid particles on depletion in activity by passing a fluid for activation through the treatment zone in a direction opposite to the flow direction of the fluid to be treated, wherein the solid particles are washed to remove contamination by removing a portion of the solid particles, during the passing of the fluid to be treated, through an outlet position upstream of the flow direction of the fluid to be treated into a washing zone which is separate from the treatment zone to wash the removed portion of solid particles and, after washing, recycling the washed solid particles into the treatment zone. In Example 4, benzoic acid is removed from an aqueous solution of a polymeric surfactant by passage through a bed of activated charcoal which is subsequently regenerated by caustic soda solution.
