Summary: In this study, the effects of three types of dissolved organic matter (DOM) derived from fresh chicken manure (FDOM), immature compost (IDOM) and mature compost (MDOM) on the adsorption of Pb onto montmorillonite (MMT) were compared. The potential mechanism was revealed through characterization of mineral structure and calculation of interface force. The results showed that the presence of FDOM and IDOM decreased the adsorption capacity of Pb onto MMT, while the presence of MDOM increased it, due to the release or co-adsorption of DOM-Pb complexes. The study provided insight into the behavior of livestock manure and its compost as well as their interactions with heavy metals and soil minerals.

Summary: Accelerated glacier melt and runoff contribute labile dissolved organic matter (DOM) into downstream ecosystems, where it undergoes substantial processing and transformation before entering the ocean. Molecular and optical techniques reveal that glacial DOM is primarily composed of small microbial-derived biomolecules, which are processed downstream into more complex molecules. Lakes along the flow path enhance water residence time and facilitate DOM processing and production.

Summary: Antibiotic pollution from manured farmland soils is a major public concern. This study investigated the leaching behavior of sulfadiazine and florfenicol with manure-dissolved organic matter, and found that soil hydrological processes and heavy rainfall events accelerated the leaching of antibiotics. Manure-dissolved organic matter reduced the mass flux of sulfadiazine but facilitated the transport of florfenicol.

Summary: Catalytic membrane based oxidation-filtration processes (AOP-CM) provide an efficient water purification strategy by combining physical separation and chemical oxidation. However, the low efficiency of heterogeneous AOPs in catalytic membranes has hampered the application of AOP-CM. To improve the efficiency, an isoporous AlOx/La2CoMnO6-delta ceramic membrane (IAPCM) with nano-confinement characteristics was prepared. The well-designed pore structure of IAPCM resulted in excellent water permeance and size-exclusion performance. Addition of peroxymonosulfate (PMS) enabled ultrafast degradation of organic micropollutants in the IAPCM system. This work emphasizes the significance of pore structure design for high-performance AOP-CM processes.

Summary: In this study, different operation modes were introduced to the gravity-driven membrane (GDM) process without aeration, backwashing, and chemical cleanings, aiming to develop simple and economic flux regulating strategies. The intermittent GDM system achieved higher stable flux levels and self-sustained operation compared to the continuous GDM case, due to the synergetic effects of forming more permeable structures and reducing the concentrations of EPS and SMP within biocake layers. The optimized daily operation mode was 16 h on / 8 h off, considering the trade-off effects between membrane flux level and water production.

Summary: This study utilized FF-EEM for the nondestructive and in situ characterization of algae fouling in UF systems, as well as analyzing its mechanisms and reversibility. The results showed a linear correlation between phycocyanin fluorescence on the membrane surface and algal cell count, and a decrease in membrane fluorescence as fouling progressed. The plateau in membrane fluorescence indicated full coverage and deterioration of fouling reversibility. These findings highlight the promise of FF-EEM as a valuable tool for monitoring and evaluating cyanobacteria fouling in UF systems.

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.
