ABSTRACT:
A method of removing waste oil from industrial oily waste water is disclosed. The method comprises the steps of adding to the oily waste water which includes oil, dispersed solids and emulsified water, an effective amount of a demulsifier which comprises a copolymer of a cationic monomer and a vinyl alkoxysilane; allowing the oil, emulsified water and dispersed solids to flocculate and separate into layers; and then removing the water layer from the treated waste water. The cationic monomer is selected from the group consisting diallyldimethylammonium halide, dimethylaminoethyl acrylate quaternary salt and dimethylaminoethyl methacrylate quaternary salt.
