  • System and method for recovering oil from a waste stream
    Publication number: 20050194323
    Abstract: The systems and methods recover oil from an emulsified waste stream. A coagulating agent and/or a flocculating agent, or both, are added to the emulsified waste stream to accelerate separation into an aqueous stream and a thickened emulsified stream. The coagulating agent can comprise alum. The flocculating agent can comprise a cationic polymer. Separation of the thickened emulsified stream into an oil-rich component, a second aqueous component, and a solid cake can be effected by mechanical separation in a centrifuge, filter, or press.
