Abstract: The present invention relates to a continuous bipolar electrochemically based reactor for the purpose of destroying free cyanide by direct and indirect oxidation and removing its strong complexes like ferrocyanide and ferricyanide by electrocoagulation. The designed reactor consists of four main sections, including electrooxidation, hydraulic mixing, electrocoagulation, and precipitation tank. The order of sections results in having a combination of reactions which separately remove cyanide and its compounds. The designed reactor shows a high flexibility in terms of handling highly variable kinds and concentrations of cyanide in the industrial wastewater effluents.
