  • How to treat electroplating wastewater?
  • There are several processes reported to treat electroplating wastewater such as chemical precipitation, adsorption, coagulation and flocculation, ion exchange, electrocoagulation, membrane filtration, advanced oxidation process and biorecovery. These methods provide the possibility to capture different toxic metals and remove organic pollutants.
  • 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.
  • Can electroplating wastewater be treated in developing countries?
  • The application of these treatment techniques is problematic to the developing countries as a high technique. The most applicable process for the treatment of electroplating wastewater is neutralization followed by sedimentation ( Abdel-Shafy et al. 2025 ).
  • Is electroplating wastewater harmful to the environment?
  • The electroplating wastewater is harmful to the environment [ 14, 15, 16, 17 ], as well as pose adverse effects on human health, which must be treated before being discharged [ 18, 19, 20, 21, 22 ]. Solid–liquid separation is an important step in electroplating wastewater treatment.
