Abstract
A method and apparatus for reducing the concentration of haloorganic compounds in water-contaminated with haloorganic compounds is disclosed. The haloorganic compounds are extracted from the water and concentrated into certain water immiscible alkane hydrocarbon solvent. The solvent is separated from the water, is regenerated by ultraviolet radiation to degrade the haloorganics, and is recirculated to contact additional contaminated water. After extraction the water separated from the solvent may be subjected to conventional drinking water treatment, or passed to groundwater.
