  • Does electrochemical advanced oxidation of metal plating wastewater remove heavy metals?
  • A kinetic model incorporating the key reactions occurring in the electrolysis process has been developed, which satisfactorily describes EDTA, Cu, Ni, and TOC removal. Overall, this study improves our understanding of the mechanism of removal of heavy metals from solution during the electrochemical advanced oxidation of metal plating wastewaters.
  • Can electro-coagulation remove heavy metals from electroplating wastewater?
  • The application of the electro-coagulation process proved to be an efficient treatment technology for the removal of metals from electroplating wastewater. Combination of lime and ferric chloride was more efficient for the precipitation of heavy metals from industrial electroplating wastewater than other chemical coagulants.
  • What is industrial electroplating rinsing wastewater?
  • A real industrial electroplating rinsing wastewater was collected and subjected to physical and chemical examination. The study showed that it can be categorized as high strength wastewater, at pH- 2, COD 1430 mg/l, and high level of metals above permissible limits, namely: 150, 30, 25, and 2.9 for Ni, Cu, Zn, and Fe mg/l respectively.
  • How is waste solution used in electroplating & electroless plating industries?
  • With the continuous development of the electroplating and electroless plating industries, a large amount of waste solution is generated every year, mainly including spent plating solution and plating pieces rinse wastewater. The discharge standard of waste solution is also continuously improved.
