ABSTRACT:
A process for the purification of waste water containing grease and soil, especially the effluent from wool-soaking and wool-washing, which comprises mixing the waste water with a heavy solvent; separating the emulsion formed to obtain degreased water, a small quantity of water-solvent emulsion, and solvent charged with greasy matter and soil; clarifying this solvent to separate the soil; subjecting the clarified solvent to an azeotropic distillation in the presence of water, to form an emulsion from which the greasy matter can be recovered, and a head product from which the solvent can be regenerated, and apparatus therefor.
