In wastewater treatment process of electroplating and circuit board manufacturing, ion exchange has excellent performance in collection of various impurity ion in heavy metal liquid waste, especially in absorption of metal with electric charge. Therefore, it not only can discharge and collect waste water, but also recycle metal ion in waste water.
