Abstract
1382537 Purifying water CHEMISCHE WERKE KLUTHE KG 5 June 1973 [6 June 1972 2 Dec 1972] 26831/73 Heading C1C A composition for purifying waste waters by the precipitation or flocculation of impurities therein in a neutral medium, comprises an alkaline earth metal halide, iron (III) halide, an alkali metal aluminate and polyacrylamide. Among waste waters purified are aqueous cleansing solutions, lacquers on a water base, oil-in-water emulsions, and water-in-oil emulsions such as drilling oil emulsions, rinsing water from electrophoresis plants, cutting compound emulsions, cooling lubricant emulsions, communal sewage, waste water containing oils and fats of animal, vegetable and mineral origins and/or mixed organic-inorganic contaminants and/or surface active agents. Compressed air may be used to assist mixing and/or filtration.
