Summary: The study developed a novel electrocoagulation membrane reactor and systematically investigated key operational conditions to determine their synergistic influence on reactor performance. It was found that the reactor exhibited optimal antifouling behavior, with pH and current density affecting fouling mitigation. Increasing applied voltage led to a stronger repulsion force and looser fouling layer, ultimately decreasing flux decline. This study provides a simple and feasible strategy for fabricating a novel electrocoagulation membrane reactor to address membrane fouling issues.

Summary: This study investigates the use of diffusion coefficients as surrogate indicators for evaluating the electrostatic repulsive forces between natural organic matter (NOM) and ultrafiltration (UF) membrane surfaces. The results demonstrate a strong correlation between the reduction in diffusion coefficients and the heightened electrostatic repulsion when membranes rich in ionizable functional groups with strong negative charges are involved. This innovative approach contributes to proactive and predictive assessments of membrane performance and enhances the operational efficiency of water treatment facilities.

Summary: This study evaluated the electrochemical reduction and separation of model contaminants from water. The results showed that a carbon nanotube (CNT) membrane as a cathode could remove 90% to 95% of the contaminants tested. The process of removing hexavalent chromium ion (Cr(VI)) involved reduction to Cr(III) followed by adsorption onto the cathode, which could be efficiently regenerated. Preliminary findings also suggested that AC current could be a feasible approach for detoxification.

Summary: The development of acid resistant nanofiltration membranes (ARNFMs) with high metal rejection, high flux, and low molecule weight cut-off (MWCO) is a challenge. In this study, a novel post-treatment method using citric acid (CA) was used to enhance the separation performance of dually charged polyamine ARNFMs. The CA treatment effectively removed oligomers and reacted with redundant amino, imine, and hydroxyl groups. The treated membranes showed significantly improved flux, high MgCl2 rejection, and low MWCO. The CA treatment did not affect the acid stability of the membranes, and even protected them from the harmful effects of hydrochloric acid. This study demonstrates the potential application of CA-treated polyamine ARNFMs in acidic wastewater treatment.

Summary: In this study, La and Fe bimetallic supported zeolite was successfully synthesized for efficient defluoridation. The research found that under optimal conditions, the removal efficiency of fluoride ions reached 99.04%. Additionally, it was discovered that CO32- and HCO3- inhibited the defluorination effect of the zeolite. Dynamic adsorption column test showed that even after continuous adsorption for 9 hours, the La-Fe zeolite still maintained an adsorption efficiency of over 85%. Mechanism analysis revealed that the adsorption process involved both ion exchange and complexation, belonging to a physicochemical process.

Summary: The trade-off between micropollutant abatement and bromate formation is inevitable during the ozonation of bromide-containing water. To overcome this compromise, a novel adsorption enhanced membrane contact ozonation (AEMCO) process was developed, which accelerated the oxidation of micropollutants and reduced the formation of bromate. In the AEMCO process, the removal efficiency of ciprofloxacin was 97.15% while the yield of bromate was 0.7 μg/L, compared to 39.96% and 8.3 μg/L in the conventional MCO process. Additionally, a reformative Hatta number (Ha-CIP) was used to evaluate the relationship between interface adsorption and chemical reactions, guiding the adjustment of operating parameters. These findings provide a potent strategy to balance micropollutant abatement and bromate formation during the ozonation process.

Summary: In this study, electro-Fenton and membrane distillation were combined to remove salt and TOC from glyphosate wastewater. A membrane-based electrode was used to transfer vapor and oxygen bidirectionally and synthesize H2O2 electrochemically. The operating conditions of membrane distillation promoted Fenton reactions and greatly improved glyphosate removal. The deposition of Fe species on the membrane-based electrode enhanced its catalytic activity and adsorptive capacity, leading to a 6-fold increase in the apparent reaction rate constant of glyphosate. This novel process simultaneously removed organics and concentrated inorganics, reducing subsequent crystallization costs and producing high-quality crystal salts.

Summary: The conventional microbial electrolysis cell (MEC) shows low efficiency in removing nitrobenzene (NB) due to insufficient mass transfer. Electrochemical filtration (EF) was combined with MEC to form an EF-MEC system, which increased the NB removal rate by 6.5 times compared to conventional MEC. EF enhanced the convection mass transfer of NB, leading to its increased removal. The EF-MEC system relieved the toxic effects on anode biofilms, enriched electroactive microorganisms, and promoted NB removal.
