Summary: This study investigated the removal of antibiotics and antibiotic resistance genes (ARGs) in an anaerobic membrane bioreactor (AnMBR) for high-strength antibiotic pharmaceutical wastewater. The results showed that the membrane biofilm had a positive effect on AnMBR treatment, improving the removal efficiency of chemical oxygen demand (COD) and levofloxacin (LEV) by 12% and 10%, respectively. The membrane biofilm also effectively reduced the dissemination of ARGs and class 1 integrator (intI1), with the ARGs abundance in the effluent of the medium fouling (MF) biofilm being significantly lower. The study indicated that AnMBR is effective for antibiotic wastewater treatment, with the membrane biofilm playing a crucial role in the removal of antibiotics and ARGs.

Summary: High-rate processes have been studied to recover organic matter from municipal wastewater. The use of high-rate membrane bioreactors (HR-MBRs) enables increased carbon recovery and high effluent quality, although controlling membrane fouling is challenging. To address severe fouling in HR-MBRs, a combination of granular scouring and frequent chemically enhanced backwashing was examined. The use of robust flat-sheet ceramic membranes allowed for the application of these cleaning strategies. resulting in a low fouling rate and high efficiency.

Summary: An anaerobic membrane bioreactor (AnMBR) was used to treat domestic sewage at 15 degrees C under different hydraulic retention time (HRT) conditions (6, 12, 16, and 24 h). The viability of microbial community in anaerobic digestion was assessed using Propidium monoazide (PMA)-PCR, which targeted microorganisms with intact cell membranes. The study found that a 6-hour HRT resulted in poor treatment performance, with low chemical oxygen demand removal efficiency and high mean trans-membrane pressure and flux. PMA-PCR combined with next-generation sequencing provided better identification of microbial changes compared to conventional 16S rRNA gene sequencing.

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: 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.

Summary: A transmembrane electro-chemisorption system with authigenic acid and base was developed for enhancing ammonia recovery from strong ammonia wastewater. The system efficiently transformed ammonium into free ammonia, which was then adsorbed and recovered through transmembrane chemisorption. This system yielded pure (NH4)2SO4 product and produced valuable byproducts of pure hydrogen and oxygen. Higher applied voltage resulted in better ammonia recovery.

Summary: To meet the huge demand for lithium resources, there is an urgent need to develop a new efficient technology for lithium recovery from salt-lake brines. In this study, a selective membrane capacitive deionization system is reported, which achieves high lithium recovery capacity and rate through the use of materials with efficient intercalated pseudo-capacitance and a high specific area porous carbon. The use of a modified thin-coated membrane allows for selective Li+ recovery, and adjusting the concentrations of Li+ and Mg2+ in the feed solution enables higher Li+/Mg2+ selectivity.
