A Green Future For Scrap Iron
September 12, 2008
In a five-year project that progressed from benchtop to pilot to full-scale tests, engineers from Lehigh University in Bethlehem, Pa., and Tongji University in Shanghai showed that the biological treatment of industrial wastewater can be dramatically enhanced by pretreating the waste with non-oxidized iron. The group's full-scale test at a treatment facility in Shanghai's Taopu Industrial District was the largest in history to use iron in an environmental application.
