FIELD: cleaning oil from contaminants by crossing micro-filtration.
SUBSTANCE: proposed method includes circulation of oil above surface of reinforced membrane which is supported by tube provided with open pores and made from fiberglass plastic, carbon fiber reinforced plastic or organic plastic. Micro-filtration of oil is performed through fluropolymer membrane filled with kieselguhr or bentonite at size of pores from 0.1 to 0.5 mcm. Method is realized at rate of 2-3 m/s under pressure of 0.05-0.3 Mpa at temperature of 20-60°C.
EFFECT: enhanced efficiency of cleaning oil.
