Abstract

The invention relates to a process and an apparatus for the separation of a dispersed phase in emulsion or in suspension in a continuous phase of a different density. The process comprises causing the emulsion to circulate in a coalescing enclosure (1) containing a filling (11) having an inherent volume of particles or fibers which is slight with respect to the useable volume of the enclosure, and causing the filling to move with respect to the emulsion in such a manner that the particles or fibers thereof sweep the enclosure with an average speed which is high with respect to the flow speed of the emulsion in the enclosure. The invention is particularly applicable for the separation of hydrocarbons or fatty bodies dispersed in an aqueous effluent.
