Abstract

1470273 Treatment of an aqueous effluent containing phenols and ammonium salts SOC POUR L'EQUIPMENT DES INDUSTRIES CHIMIQUES SPEICHIM 26 March 1975 [26 Nov 1974] 12733/75 Heading C1C A process for the treatment of an aqueous effluent containing phenols and ammonium salts, comprises adding sufficient caustic alkali to the said effluent to convert the ammonium salts derived from strong acids into ammonia, heating the resulting liquid mixture partially to evaporate same and remove, as vapour, ammonia and other volatile constituents, heating to evaporate the remaining liquid to produce vapour and a concentrate, scrubbing the vapour so obtained with a solution of caustic alkali and discharging the scrubbed vapour, removing inorganic salts and water from the concentrate to obtain an organic residue, and discharging the residue or incinerating the residue and discharging the products of its incineration.
