Summary: In this study, poly(citric acid)-grafted graphene oxide (PGO) was incorporated into single-layer hollow fiber (SLHF) and dual-layer hollow fiber (DLHF) membranes to improve their antifouling properties during water treatment. The optimized PGO loading of 0.7 wt% in SLHF membrane resulted in higher water permeability and bovine serum albumin rejection compared to the neat membrane. Similarly, introducing 0.7 wt% PGO only to the outer layer of DLHF membrane improved its antifouling properties and increased the rejection rate of bovine serum albumin to 97.7%.

Summary: In this study, PVDF-based anion-exchange membranes were designed to selectively separate nitrate from chloride. Experimental data showed that increasing the concentration of PVDF enhanced nitrate transport but also increased the membrane electrical resistance. The selectivity of nitrate was found to be independent of the membrane thickness and mainly driven by the increased affinity between the anion and the membrane.

Summary: This study focuses on the modification of a commercially available polyamide thin-film composite membrane with a zwitterionic material to enhance its fouling resistance. The modified membrane shows improved salt rejection and reduced permeability compared to the pristine membrane. Fouling tests demonstrate that the modified membrane has a lower fouling ratio and higher recovery ratio. The enhanced antifouling characteristics are attributed to the improved hydrophilicity resulting from the zwitterionic brushes and the salting-in effect.
