Abstract：

Effects of PEG400 concentration in the polysulfone (PSF) dope solution on the substrate morphology and performance of the thin-film composite (TFC) forward osmosis (FO) membranes were investigated. Thermodynamic and kinetic analysis showed that the phase inversion was faster at higher PEG400 concentration. The contact angle and porosity of the PSF substrate at various PEG400 concentrations were similar, but the reverse osmosis (RO) water permeability of the TFC FO membrane increased as the PEG400 increased. The structure parameter (S) decreased to 516 μm at PEG400 concentration of 8wt%, and then increased. The TFC FO membrane showed the highest FO water flux (Jv) at 8wt% PEG400 in both AL-FS mode (12.5 L/m2h) and AL-DS mode (23.8 L/m2h). This means that PSF-8 has the lowest internal concentration polarization (ICP).
