  • Patent number: 5730882
    Abstract: Emulsified oil contained in oil-in-water emulsions is removed from waste water by mixing cationic polyacrylamide high polymers with the waste water, forming oil-containing aggregations and separating the aggregations from the demulsified water. The demulsified water can then be more effectively polished, typically by contact with adsorbent particles, and subsequently passed to environmentally acceptable disposal locations.
