Abstract

1438427 Treating waste water DEUTSCHE GOLD-UND SILBER-SCHEIDEANSTALT 24 June 1974 [9 July 1973] 27853/74 Heading: C1C A process for treating waste water containing organic, water-insoluble substances in emulsified form to form an aqueous phase and a phase which contains the organic impurities and which is of a substantially pasty to solid consistency comprises adding to the waste water at least one water-soluble salt of a C 1-8 fatty acid with a polyvalent metal and/or halide or sulphate of sodium, magnesium, aluminium or iron in solid or dissolved form as an emulsionbreaking agent, in combination with an adsorption agent suitable for transforming the fraction which is not soluble in water into a state suitable for filtration the emulsion-breaking agent and the adsorption agent being used together with an organic, water-soluble, macromolecular flocculant and after the emulsion has been broken, the solid fraction which can be filtered is separated from the liquid phase. In the examples an emulsion of a drilling oil in water is treated with a mixture of AlCl 3 , CaO hydrophobized precipitated silica, Milori blue and kieselguhr and a flocculant which may be a polyamine polyethylene, polyacrylamide or polyacrylate.
