Short summary
One of the crucial aspects of developing a forward osmosis (FO) process is making a suitable membrane. In this work, an FO membrane was synthesized by making a polyamide selective layer on an electrospun nanofiber support layer. The prepared thin-film composite (TFC) membrane showed good performance in terms of water flux and salt rejection compared to the commercially available membranes. Also, it showed other good properties, namely porosity, hydrophilicity, and mechanical strength.
