Membranes are also suitable for treating industrial wastewater, which often contains substances that conventional sewage systems can't handle, such as mineral oils, salts or heavy metals. Industrial wastewater is thus often pretreated at company plants before it reaches the sewage system. As part of the EU sponsored Mewaprev (Metal Waste Prevention) project, Frank Walachowicz and his team of engineers at Siemens Corporate Technology in Berlin have developed a solution for wastewater from the electroplating industry. Electroplating involves the application of a thin layer of metal to a plastic or metal surface. It is used to enhance vehicle parts, cell phone housings and jewelry. "These companies' wastewater contains all kinds of metallic salts, particularly salts of copper, nickel, chromium and precious metals," says Walachowicz. Although the concentration of metals in such wastewater is sometimes as high as that found in ore deposits, the metal could, until recently, not be economically recycled.
