Summary: The discharged saline wastewater has a severe impact on the aquatic environment due to the limited treatment performance of many wastewater treatment techniques. Membrane bioreactor (MBR) processes, on the other hand, have shown potential in treating saline wastewater under different salinity levels depending on the adaptation of the microbial community. This study systematically reviews the application of MBR in the treatment of saline wastewater, focusing on microbial structure and treatment efficiencies. The concept of carbon dioxide capture and storage is also proposed for MBR-based saline wastewater treatment technologies to achieve zero emission targets in the circular economy.

Summary: This research evaluated the performance of a reactive electrochemical ceramic membrane (REM) in treating secondary effluent and investigated the fate of dissolved organic matter (DOM) at the molecular level. The study found that REM effectively removed DOM through adsorption, electrosorption, and oxidation processes, leading to the degradation of fluorescence components and the formation of stable finished water. The combination of fluorescence spectroscopy and FT-ICR MS provided insights into the behavior of DOM during electro-oxidation in the REM system. These findings are significant for understanding the potential of REM in different water sources and predicting the composition of DOM in finished water.

Summary: In this study, boron nitride (BN)-Co3O4 nanosheet cluster (NC) was fabricated to facilitate PMS activation for the rapid removal of ranitidine (RAN). The BN-Co3O4 NC showed highly efficient catalysis performance and could be applied in a wide pH range. The porous structure of BN-Co3O4 NC enhanced the catalytic performance by providing more channels for RAN and PMS molecules. PMS activation by BN-Co3O4 NC was mainly achieved through reduction via active radicals.

Summary: The photoelectrocatalytic (PEC) process is a promising technology for ammonia oxidation in water treatment, but limited in situ generation of oxidants, slow mass transfer, and nitrate/nitrite by-products hinder its further application. In this study, different transition metals (Ni, Fe, Mn, Co, Cu) were screened as graphite felt (GF) cathode modifiers, and the Ni-GF cathode showed the best electrocatalytic activity for H2O2 generation. The PEC system composed of Ni-GF cathode and optimized titania nanotubes (TNTs) photoanode efficiently converted ammonia to N2 without nitrate/nitrite by-products. The synergistic oxidation system demonstrated the simultaneous generation of oxidants on both anode and cathode, and reactive oxygen-based oxidants and chlorine-based oxidants played a leading role in ammonia oxidation.

Summary: Using membrane distillation with dopamine-functionalized PTFE membranes (DA@PTFE) can effectively reduce membrane fouling caused by natural organic matter in secondary effluent, thus increasing the water production rate and stability of the MD system. The DA@PTFE membranes demonstrated improved MD performance with increased flow rate and reduced flux decay compared to pristine PTFE membranes. Additionally, the DA@PTFE membranes exhibited high water quality permeate with high rejection rates of conductivity and dissolved organic carbon. This study highlights the potential of DA@PTFE membranes for real application in reclaimed water treatment.

Summary: Membrane-based nanoconfinement catalysis combined with advanced oxidation processes (AOPs) and membrane filtration can efficiently and rapidly remove organic pollutants. In this study, cobalt-ferrite-doped graphitic carbon nitride (CoFe2O4@g-C3N4) nanoconfined catalytic membranes were fabricated to activate peroxymonosulfate (PMS) for efficient water purification with the rapid degradation of pollutants. The CoFe2O4@g-C3N4 membrane/PMS system achieved a degradation first-order rate constant of 0.088 m s(-1) (5280 min(-1)), which is 10(4)-10(6) times higher than those of traditional AOP systems. The as-obtained CoFe2O4@g-C3N4 membrane expands a new pathway for membrane-based nanoconfinement catalysis and also provides a promising scheme for water treatment.

Summary: This study proposes a tandem system of dual-cathode HEF and UV radiation to overcome the conflict between the optimal potentials of the two targeted reduction reactions in the catalyst-integrated cathode-based heterogeneous electro-Fenton (HEF) process. In the dual-cathode HEF unit, efficient H2O2 production, OH formation, and Fe(iii) electroreduction are achieved by the air-diffusion cathode (ADC) and the FeOCl-functionalized graphite felt (FeOCl/GF) at different operating current densities. The underutilized H2O2 in the HEF effluent is then reactivated in the UV module to eliminate the risk of oxidant residues and improve decontamination efficiency. The proposed HEF/UV tandem strategy offers a promising scheme for distributed wastewater treatment with high process efficiency and a green chemistry concept free from reagents and residual oxidants.

By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
