FIELD: water treatment.
SUBSTANCE: invention relates to water treatment, in particular to a method of regenerating detergent and degreasing solutions. Method includes settling with separation of oil from water phase with subsequent treatment of the latter with chemical reagent and filtration. Water phase at the stage of treatment with chemical reagent is exposed to cavitation during 2–3 minutes at temperature of 60–70 °C. Reagent used is magnesium sulphate.
EFFECT: technical result consists in improvement of efficiency and stability of cleaning alkaline detergent solutions containing oil, oil products and suspended substances.
