Mar 14, 2019Values of water fluxes for support layers dropped significantly from 1750 to 0 (L/m 2 h) with a decrease in PSf concentration. A less significant tendency was found for complete TFC membranes, i.e., from 40 to 10 (L/m 2 h). This can be explained by the low porosity of the support structure with higher concentrations of polymer.
