Removing Heavy Metals From Wastewater

1. Plating Waste Treatment - Cyanide Oxidation Cyanides are widely used in the electroplating industry. The cyanide wastewater flow is treated by an alkaline chlorination process for oxidation of cyanides to carbon dioxide and nitrogen. This treatment is prior to metals removal. Industries not using cyanide will not have this treatment stage.
