Abstract:
A reactor for the treatment of wastewater solutions containing cyanide and/or dissolved organic material, comprising a container for holding a reservoir of wastewater solution having an entrance and an exit, and a plasma torch for directing a jet of plasma energy into the container from an outlet provided in the torch, characterized in that said reactor includes an open-ended tube positioned within said container such that said open-ended tube is submerged, in use, within said reservoir of wastewater solution, the plasma torch being positioned adjacent to an entrance of the open-ended tube, so that said jet of plasma energy from said torch is directed into said open-ended tube, said plasma torch and said entrance of said open-ended tube defining a gap allowing wastewater solution to enter said open-ended tube through said entrance, and thereby enabling recirculation of wastewater from said container through the inside of said open-ended tube, wherein said container comprises head space above the wastewater solution to promote separation of entrained gases from the wastewater solution.
