Short summary

Thin film composite forward osmosis membranes were prepared on a polysulfone substrate (17 wt %) as a support layer, via an interfacial polymerization reaction, to form a polyamide selective layer. The effect of the reaction times was investigated. The best results were found to be at 5 min for m-phenylenediamine and 1 min for trimesoyl chloride reaction times, respectively. These results gave the best performance of forward osmosis membranes in terms of water flux and salt rejection.
