ABSTRACT:
Surfactants in an aqueous solution is recovered from polychlorinated biphenyls and other aromatic organic compounds contaminating the solution. An electrical current is passed through a surfactant-containing aqueous solution contaminated with a colloidal dispersion of organic compounds at a voltage sufficient to electrochemically breakup the dispersion without polymerizing the surfactant. The contaminating aromatic organic compounds are then separated from the surfactant-containing aqueous solution. The separated surfactant-containing aqueous solution may be recirculated to a waste treatment process for cleaning additional organic compounds from contaminated equipment.
