FIELD: decontamination and utilization of bearing oil products liquid wastes, lubricant-cooling liquids water emulsions. SUBSTANCE: method allows to separate waste lubricant-cooling liquids for fractions. In the case separated fractions quality allows to use them in production. To exercise the method waste lubricant-cooling liquids are heated to temperature of 40 - 45 C and are subjected to separation in field of centrifugal forces action. This causes formation of two phases - water and oil, that are separately subjected to additional separation. Water phase is in series added with alkaline, salts of aluminum and iron. Oil fraction is additionally separated by settling for fractions - industrial waste oil and water-oil concentration emulsion. EFFECT: improved separation of water and oil fractions. 1 dwg
