| abstract | 2103247 9222504 PCTABScor01 A method of treating waste water to remove contaminants therefrom comprises (a) treating the waste water with calcium carbonate under oxidising conditions and separating a precipitate containing Al and Fe hydroxides, therefrom; and (b) treating the partially neutralised waste water from step (a) with sodium carbonate and separating a precipitate containing further contaminants therefrom including at least one of Zn, Cu, Co, Ni, Cd, Al and Fe; and optionally also comprises (c) treating the liquid phase product of step (b) with one or more fatty acids or salts thereof to precipitate further contaminants therefrom, including at least one of Ca, Mg, and Mn, and (d) treating the liquid phase product of step (c) with one or more fatty acid amines to precipitate anionic contaminants therefrom including at least one of sulphate, phosphate and chloride ions. |
