Abstract

1509042 Treating waste water BENCKISERKNAPSACK GmbH 17 March 1975 [15 March 1974] 11026/75 Heading C1C Oils, solvents and paints are removed from waste water by adding an adsorbing agent comprising a modified polysaccharide having anionic or cationic properties together with a cationic or anionic flocculation agent. The adsorbing agent gives a floating mass containing the oil, solvent or paint, which is easily removed.
