Correlation of polymer concentration with the membrane performance of polyethersulfone membrane for humic acid removal

In this study, the effect of the polyethersulfone (PES) polymer concentration toward the membrane filtration performance was studied. Moreover, the synthesized membrane was characterized with porosity measurement followed by the determination of pure water flux as well as humid acid (HA) rejection....

Description
Summary:In this study, the effect of the polyethersulfone (PES) polymer concentration toward the membrane filtration performance was studied. Moreover, the synthesized membrane was characterized with porosity measurement followed by the determination of pure water flux as well as humid acid (HA) rejection. The results showed an increase in the percentage of HA rejection and flux recovery ratio (FRR) value and a decrease in membrane permeate flux was due to an increase in the concentration of polymers. Furthermore, the results showed that complete blocking was the dominant fouling mechanism in this study except for 12 wt% PES membrane. For the 12 wt% PES membrane, the mechanism was controlled by the standard blocking mechanism which was well predicted the flux decline of PES membrane. Indeed, 15 wt% PES membrane has been chosen as the best membrane in this study, since its shown outstanding performance in terms of both HA rejection and membrane permeate flux.
