FIELD: separation of stable water-oil emulsions. SUBSTANCE: method involves preliminary purification, ultrafiltration, adding of calcium hydroxide (its quantity being 4-50 g/l) into thus prepared concentrate. The process is followed by thermostatic control within 3-75 h at 20-95 C, utilization of thus prepared oil phase and regeneration of membrane agents. Said regeneration takes place with the help of aqueous phase being prepared and having pH 9.5-12.5. EFFECT: improves efficiency of the method. 1 tbl, 1 dwg
