Abstract
An apparatus and method for removing hydrocarbon contaminants and heavy metal ion contaminants from wastewater stream comprising the introduction of iron ions into the stream. In one embodiment, the ions are introduced by applying an electrical current through a bed of iron particulates in the form of steel wool and iron nodules. In another embodiment, the iron salts are added to the waste stream and the iron ions are reduced to a more reactive lower valence state by electric current.
