Application of membrane technology in industrial wastewater treatment and reuse
Membrane technology is applied in industrial wastewater treatment and reuse to recover valuable components from wastewater and reuse the permeate after removing impurities in relevant processes, saving resources and water while preventing environmental pollution. The earliest and most mature application is the use of reverse osmosis (RO) or electrodialysis (ED) technology to treat electroplating wastewater, such as wastewater containing nickel, chromium, copper, zinc, and other metals, recovering these metal ions and reusing the water for rinsing. Due to the high value of chromium and nickel reuse, many countries focus on the treatment of chromium-containing and nickel-containing wastewater. Another
