Summary: Consumers are increasingly aware of the importance of incorporating functional and nutritional foods into their diet, leading to a higher demand for protein and peptide-rich food extracts. Soy protein and its derivatives are particularly emphasized in this trend. Ultrafiltration membranes are used for protein fractionation and concentration, but membrane fouling remains a key limitation caused by the accumulation of macromolecules near the membrane surface.

Summary: The study demonstrated that natural surfactants can enhance the hydrophilicity of algae interface and stability of algae-laden water, reducing algae aggregation. While SDS or LAS aggravated membrane fouling in the initial filtration process, it alleviated fouling later on due to a looser cake layer formation. Surfactants led to more pore blocking in the early stage, resulting in a significant decrease in total flux. Additionally, SDS or LAS reduced disinfection byproduct formation potential by degrading free available chlorine, but increased algal toxins concentration in ultrafiltration effluent, indicating a high impact on separation performance.

Summary: This study proposes a novel heat-activated peroxydisulfate (heat/PDS) process for cleaning membrane fouling caused by humic acid (HA). The combination of heat and PDS can achieve almost 100% recovery of permeate flux by changing the HA structure and enhancing foulant detachment from membranes. The properties of treated membranes are characterized, and the results demonstrate the effective removal of reversible and irreversible foulants by heat/PDS cleaning. The heat/PDS method shows comparable performance to NaClO in membrane cleaning and provides high performance in removing fouling caused by different substances, suggesting its potential as an alternative for practical membrane cleaning.

Summary: In this study, ferrate (Fe(VI)) and calcium sulfite (CaSO3) were combined to improve ultrafiltration (UF) performance in surface water treatment. The combination of Fe(VI) and CaSO3 generated various active species, effectively eliminating fluorescent components. Dissolved organic carbon and UV254 were significantly reduced with Fe(VI)/CaSO3 = 0.05/0.15 mM. After UF, the removal rate for these parameters were further improved. The UF stage also resulted in reduced fouling and improved membrane performance.

Summary: This study focused on the preparation, characterization, and sulfamethoxazole (SMX) removal performance of a SnO2-coated reactive electrochemical membrane (REM). The REM, fabricated by loading SnO2 on a reduced TiO2 nanotube arrays (RTNA)-based Ti membrane (TM), showed improved SMX removal efficiency in flow-through mode compared to batch mode. The presence of Sb as a dopant in SnO2 enhanced the electrocatalytic activity, leading to lower energy consumption compared to Bi-doped SnO2. The TM/RTNA/ATO demonstrated stability and durability in multi-cycle and accelerated lifetime tests, making it promising for water treatment applications.

Summary: The interfacial polymerization process between piperazine (PIP) and trimesoyl chloride (TMC) was effectively regulated using a weak-polar organic solvent of ethyl formate (EF) to fabricate polyamide (PA) nanofiltration (NF) membranes with high ion selectivity and water permeability. Molecular dynamics (MD) simulation revealed that EF involvement reduced interfacial tension and facilitated the diffusion of amine monomers into the organic phase, resulting in a PA film with higher crosslinking degree. The optimized PA NF membranes exhibited efficient rejection for divalent anions and cations, and high mono/divalent ion selectivity at sub-angstrom size.

Summary: Marine harmful algae bloom (HAB) poses a threat to desalination plants worldwide. This study proposes a new pretreatment technology using ferrous iron/peroxymonosulfate (Fe2+/PMS) for seawater reverse osmosis (SWRO) under HAB. Fe2+/PMS achieved improved flocculation and removal of algal cells, turbidity, and algal organics matters (AOMs). The seawater matrix enhanced the generation of high-valent iron (FeO2+), leading to improved coagulation efficiency. Fe2+/PMS also resulted in reduced membrane fouling and lower operational cost compared to conventional coagulation techniques. This technology shows promise for high-performance and low-cost pretreatment for seawater desalination plants under HAB conditions.

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.
