UTILIZATION OF WASTEWATER OF THE ZINC-NICKEL PLATING PROCESS
Several bathes for electroplating contain amine-based compounds. For example, modern alkaline electrolytes for deposition a zinc-nickel alloy. Amine-based compounds form strong, well-soluble complexes with heavy metals, which greatly complicates the purification of wastewater. As a result of the work, the wastewater treatment technology has been developed, which includes the following stages: preliminary reagent treatment; electrochemical cleaning using copper-plated carbon fiber; subsequent reagent post-treatment.
