  • What methods are used in electroplating wastewater treatment?
  • To prevent the harmful effects generated by the existence of these chemicals, many conventional methods directly being applied for electroplating wastewater treatment such as chemical precipitation, ion-exchange , membrane filtration , adsorption .
  • Can adsorption process be used as single stage wastewater treatment?
  • Abstract—The wastewater treatment process was evaluated in an Electroplating unit that practiced chrome and bronze plating. With a view to recycle and reuse the wastewater, adsorption process was adopted as single stage treatment instead of the existing chemical methods.
  • Can electroplating be used to remove copper and chromium from wastewater?
  • In the present study an Electroplating unit employing chrome and bronze plating was selected for process evaluation, removal of copper and chromium from wastewater and exploring the scope of recycling. The chemical treatment was planned to be replaced by physico-chemical process like adsorption.
  • How does Batch adsorption of heavy metals remove from electroplating wastewater?
  • The batch adsorption process of heavy metals removal from electroplating wastewater is factored by contact time, dosage, temperature and pH. The heavy metals removal efficiency by the nano-adsorbents is in the order of PHB-CNTs > P-CNTs based on the high surface area and more functional groups of the former than the latter.
