Abstract

1535597 Purifying effluents CREUSOT-LOIRE 18 May 1976 [5 June 1975]20462/76 Heading C1C Effluents polluted with liquids and in the form of emulsions are treated by recycling the polluted effluent between a reservoir and a treatment apparatus in which in each cycle at least part of the effluent is subjected to an ultrafiltration treatment which removes unpolluted effluent and increases the concentration of pollutant in the polluted effluent, and at least part of the effluent is treated with a coalescent which causes coalescence of the particles of pollutant and removes the coalesced pollutant to reduce the concentration of pollutant in the polluted effluent. The method is used to separate oil-in-water emulsions. Apparatus for carrying out the method is described.
