USE OF CATIONIC COAGULANT AND ACRYLAMIDE POLYMER FLOCCULANTS FOR SEPARATING OIL FROM OILY WATER
摘要
Methods for treating oily wastewater comprising adding to the wastewater a cationic coagulant and an acrylamide copolymer flocculant. The acrylamide copolymer flocculant may comprise either an anionic acrylamide copolymer flocculant or a cationic acrylamide copolymer flocculant or both. The acrylamide flocculants may be present in an emulsion or mixture along with activated starch or maleamate derivatized starch. The method may be employed for example, to clarify SAGD and/or frac produce waters
