P O R E X F I LT R AT I O N | CASE STUDY ELECTROPLATING ® POREX Tubular Membrane Filter (TMF™) Applied in Copper/Nickel Wastewater Treatment System for an Electroplating Industry Park Abstract Plating is a widely used process across many industries and is also one of Introduction the most fragmented of industries. Due to its historic development, the electroplating industry in China has several common characteristics: small in scale, low degree of specialization, inefficient production lines, and marginal economic return. In addition, many of these facilities are often located close to residential areas. This can create significant environmental problems as electroplating can produce toxic solid and liquid waste and air pollution in the proximity of the plant. Most of the electroplating factories in China are small in scale, and for some manufacturing facilities, plating is just an auxiliary workshop attached to a large factory. These characteristics often cause many disadvantages for these businesses such as: high monetary investment, large amount of wastewater effluent, difficult wastewater collection, repeated cycles in a Waste Water Treatment Plant (WWTP), plus high construction and operating cost for the WWTP. In recent years many local governments in China
