  • How much wastewater does electroplating produce a year?
  • Industrial electroplating process and surface treatment produce a large amount of wastewater. By the end of 2021, there were more than 10,000 electroplating plants and more than 5000 electroplating production lines in China, which discharged approximately 400 million tons of wastewater containing heavy metals every year (Qu et al., 2021).
  • What is electroplating wastewater?
  • Sci. Eng.774 012092DOI 10.1088/1757-899X/774/1/012092 Electroplating wastewater is a highly hazardous industrial wastewater with complex composition. For the treatment of electroplating wastewater, the traditional treatment methods include chemical treatment and membrane treatment.
  • How much money does China spend on electroplating wastewater?
  • It is about 45% of all industry wastewater being produced every year. 15 billion Chinese Yuan are being used to treat those electroplating wastewater. This is account for 1/3 of all the money being used for treating industry wastewater. From the data we can see that Chinese government and companies spend a lot of money on treating those wastewater.
  • What methods are used to treat electroplating industry wastewater?
  • This article examines and assesses new approaches such as coagulation and flocculation, chemical precipitation, ion exchange, membrane filtration, adsorption, electrochemical treatment, and advanced oxidation process (AOP) for treating the electroplating industry wastewater.
