Emulsified oily wastewater treatment via fertilizer drawn forward osmosis using a corrugated thin film composite membrane

Abstract

Membrane fouling and draw solution recycle are two important challenges faced by forward osmosis (FO) process in treating wastewater. In this study, we innovatively designed a corrugated TFC FO membrane(#FO-C) by conducting interfacial polymerization (IP) on a commercial corrugated polyvinylidene fluoride (PVDF) substrate and utilized fertilizer as the draw solution to treat emulsified oily wastewater for mitigating membrane fouling and …
