FIELD: chemistry.
SUBSTANCE: invention relates to organic chemistry and can be used for purification of process and waste water from petroleum, oil products and other hydrocarbons, including fuel oil, gasoline, kerosene, oil, lubricant-coolant, solid suspended particles, including fine particles of sand, clay or from complex aqueous emulsion-suspension mixtures. A reagent for destabilizing an oil-water emulsion and suspension, containing sodium alkylamino-phosphonate, sodium aminomethylene phosphonate and water.
EFFECT: invention reduces residual content of impurities in purified water with simultaneous increase in the degree of demulsification of oil products.
