Abstract

An improved method and apparatus for the removal of both suspended and dissolved contaminants be they heavy metals, organics, inorganics, hydrocarbons and others from various types of waste stream, wash water, ground water, leach waters, process waters and etc. is illustrated. The method combines passing the aqueous waste stream through an electromagnetic field, an ozone/oxygen venturi injector for oxidation and then through a horizontal flow and vertical fall with a horizontal plate maze unit of alternately electrically charged plates, anode and cathode. The plates will be charged, selectively: by either DC or AC Voltage and Current. There will be provisions for installation of a framework to mount and support a polar/bi-polar membrane, divider or separator as may be required to enhance special treatment of particular aqueous waste streams.
