In this study, we aimed to develop a forward osmosis (FO) thin film composite (TFC) membrane which could retain NH4+ from wastewater. The conventional TFC membrane has a microporous polymer support and a selective layer for salt rejection; however, the polyamide selective layer is known to not be ab...
