Summary: This study investigated the effect of interfacial polymerization temperature on the properties of thin film nanocomposite (TFN) nanofiltration membrane containing surface-functionalized graphene oxide (GO). The membrane developed at 55 degrees C exhibited a more cross-linked and rougher polyamide layer, resulting in excellent Na2SO4 rejection. However, it also had higher protein adhesion due to the rougher surface. On the other hand, the TFN membrane developed at 0 degrees C had a thin and smooth polyamide layer, resulting in higher water flux and improved antifouling performance.

Summary: Polyamide (PA) membranes used in reverse osmosis and nanofiltration can be degraded by bromination under chlorinated bromide-containing water conditions. This study addresses the misconception that only hypobromous acid (HOBr) is responsible for membrane degradation, while other more reactive but less abundant brominating agents are often overlooked. The findings show that the rate of membrane degradation is strongly correlated with bromide, chloride, and hypochlorous acid concentrations.

Summary: The papermaking industry generates large amounts of wastewater and waste gas, and their treatment often involves the use of chemicals, lacks resource recovery, and consumes high amounts of energy. In this study, a chemical self-sufficiency zero liquid discharge (ZLD) system called NF-BMED-MC was designed to recover resources from papermaking wastewater and waste gas. This integrated system has shown great synergy by utilizing nanofiltration, bipolar membrane electrodialysis, and membrane contactor technologies. It enables the recovery of NaCl, generation of HCl/NaOH, and CO2 capture, while achieving efficient water recovery and resource purification without the need for additional chemicals. The study also demonstrates the potential of NF-BMED-MC as a sustainable alternative for the ZLD treatment of papermaking industry discharges.

Summary: Understanding the kinetics of interfacial polymerization (IP) reaction is crucial for tailoring the characteristics and performance of reverse osmosis (RO) membranes. In this study, the kinetic behavior and film characteristics of polyamide (PA) film formation by IP reaction between M-phenylenediamine (MPD) and trimesoyl chloride (TMC) were investigated using the absorbance spectroscopy (AS) method in real-time. The results showed that monomer concentration and reaction time significantly influenced the kinetics of the IP reaction. The study confirmed the potential of the AS method for predicting the characteristics and optimizing the conditions of IP to achieve customized RO and nanofiltration (NF) membranes.

Summary: Viruses in the effluent and on the membrane during UF processes pose hidden biosecurity risks to drinking water. Fe3+ coagulation combined with H2O2 creates an in situ membrane cleaning method, and MS2 bacteriophage was used to investigate virus removal in the presence of humic acid (HA). The study found that HA removed MS2 based on size exclusion, hydrophobicity, and electrostatic repulsion, while Fe3+ pretreatment eliminated MS2 by iron floc adsorption and size exclusion, and iron flocs-H2O2 cleaning completely eliminated MS2. The study provides a potentially useful and cost-saving membrane cleaning method for virus-containing water treatment.

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.
