Filtration membranes are better but so far can't withstand the harsh conditions and high chemical concentrations found in pulping wastewater.  Georgia Institute of Technology researchers have found a method to engineer membranes made from graphene oxide, a chemically resistant material based on carbon, so they can work effectively in industrial applications. The researchers are Sankar Nair, Zhongzhen Wang, and Chen Ma from the School of Chemical and Biomolecular Engineering, Meisha Shofner and Scott Sinquefield from the Renewable Bioproducts Institute, and Chunyan Xu with the School of Civil and Environmental Engineering.
