Summary: Hollow fiber membranes (HFMs) have desired properties such as high surface area and filtration efficiency, but are prone to breakage or damage during high-pressure cleaning. Using braid reinforcing as support, such as in braid hollow fiber membrane (BHFM), can improve mechanical strength and enable application under higher pressure conditions. This review explores fabrication parameters and methods for enhancing BHFM performance.

Summary: This study developed a new symmetric and ultrathin membrane by incorporating Schiff base network-1 (SNW-1) nanoparticles, as fillers, into the sulfonated poly ether ketone (SPEK) matrix to improve forward osmosis (FO) performance. The modified membrane loaded with 20 wt% SNW-1 (COF-20) exhibited significantly higher water flux and lower specific reverse solute flux compared to the unmodified SPEK (COF-0) membrane. The impressive FO performances of the nanocomposite SPEK membranes suggest that SNW-1 nanoparticles could be used as fillers for improving the SPEK membrane's performance in FO applications.

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.
