Summary: By introducing HACC into the interfacial polymerization (IP) process, positively charged NF membranes were prepared. The thickness of the separation layer decreased and the hydrophilicity increased by modulating the IP process, while the pore size remained unchanged. Moreover, the quaternary ammonium group in HACC enhanced the antibacterial properties of the NF membrane. The optimized NF-HACC-0.3 membrane not only significantly improved the separation factor, but also increased the flux by 2 times. This strategy provides a valuable idea and insight for the preparation and development of Mg2+/Li+ separation NF membranes.

Summary: In this study, a new high-performance nanofiltration (NF) membrane with positively and negatively charged groups was developed for efficient Li+/Mg2+ separation. The results showed that the membrane had similar surface and section structure, as well as surface pore size, compared to the original polyamide (PA) membrane. However, the addition of Fe3+ ions improved the Zeta potential of the membrane, indicating the presence of both positively and negatively charged groups on the surface. The membrane exhibited high rejection rates for Mg2+ (97.7%) and permeation rates for Li+ (-87.6%), resulting in a high Li+/Mg2+ separation factor. The fluxes of the three membranes were comparable. These findings suggest that the NF membrane with positively and negatively charged groups has great potential for application in the recovery of lithium from brine.

Summary: This study successfully applied bipolar membrane electrodialysis (BMED) to separate inorganic salts and reclaim inorganic acids and bases from landfill leachate reverse osmosis concentrate (LLRC). The performance of BMED was improved with optimized operating parameters, resulting in higher acid-base concentrations, desalination rate, and current efficiency with less energy consumption. The reclaimed acids contained 88 wt% HCl and 12 wt% HNO3, while the reclaimed bases were 52 wt% NaOH and 45 wt% KOH. The method showed remarkable economic feasibility with a net profit of $27.630 per 1 m3 LLRC treatment. This research offers a new strategy for the sustainable utilization of inorganic salts from LLRC.

Summary: A facile route of grafting short chain amino-rich monomers (SCA) onto polyamide (PA) nanofiltration (NF) membrane is proposed for efficient Li+/Mg2+ separation. The SCA grafted NF membrane (PA-g-SCA) shows a more uniform distribution of positively charged groups on the pristine PA layer, leading to high rejection of Mg2+ and high permeation of Li+, resulting in superior Li+/Mg2+ separation performance with a separation factor of 130 even in a high WMg2+/Li+ of 200:1.

Summary: A high-performance loose nanofiltration (LNF) membrane with high water permeance and high separation accuracy was fabricated by regulating the polymer chain entanglements through changing the size of nano-CaCO3 in the casting solution. The entanglements of the polymer chains were characterized by the solution viscosity, which increased with the decrease of nano-CaCO3 size and reduced when nano-CaCO3 disappeared. The high solution viscosity and rapid phase inversion resulted in the formation of LNF membranes with outstanding performance.

However, it is difficult to incorporate these techniques with spiral wound modules (SWMs) widely used in water and wastewater treatment. This study developed a prototype membrane system to accommodate angular vibrations with a modified SWM, and experimental results showed that applying angular vibrations can effectively control algal fouling in an SWM with lower energy consumption compared to traditional methods.
