Summary: A tight polyethersulfone (PES) -based ultrafiltration (UF) membrane was fabricated to separate dye and salt in textile wastewater using a polyion complex assisted phase inversion method. The resulting membrane had a nonporous skin layer comprising of polyion complex and enriched sulfonated polysulfone (SPSF), which resulted in a smaller effective pore radius compared to the reference membrane prepared without using polyion complex assisted phase inversion.

Summary: Extracorporeal membrane oxygenation (ECMO) is a crucial therapy for patients with severe cardiopulmonary failure, but the membrane oxygenator faces challenges in balancing anticoagulation and hemorrhage risks, affecting its lifespan and patient safety. This study successfully introduces poly (1-vinyl-2-pyrrolidone) (PVP) and poly (acrylic acid) (PAA) into polyethersulfone (PES) membranes, resulting in modified membranes with favorable hemocompatibility and improved CO2 and O2 permeabilities. The modified membranes demonstrate better oxygenation and CO2 removal performances in an ECMO-simulated gas-liquid contactor circulation device. The simple, low-cost, and easily industrialized membrane modification methods in this study have practical guiding significance for future membrane research and oxygenator 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.
