Summary: This paper analyzes the impact of water flux on improving electricity generation and membrane impedance in OsMFCs. By measuring the electro-osmotic and osmotic water flux under electric fields and osmotic pressure, the relevance between water content and membrane resistance is studied. The transition from non-conductive to conductive zone within the membrane is identified as an important reason for the reduction in membrane impedance. Furthermore, the changes in membrane structure and resistance under the influence of membrane water content are also analyzed.

Summary: The study investigated the hydrodynamic characteristics of a three-phase fluidized bed reactor using a TiO2-ZnO/BAC composite catalyst for the UV-photodegradation of rhodamine 6G dye. The results indicated that a column inclination angle of 70 degrees and a gas flow rate of 0.019 ms(-1) were the optimal conditions for efficient removal of rhodamine 6G. The dominant limiting factor in the photodegradation process was found to be solid distribution.

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 paper presents an effective approach using Artificial Neural Network (ANN) to predict the Vacuum Membrane Distillation (VMD) process of sulfuric acid solution. Mathematical models were developed to explore the influence mechanisms of critical parameters on the transfer resistance in the VMD process. An ANN model was then developed from the experimental data and successfully simulated the effects of critical parameters on the VMD process performance, such as membrane flux and gained output ratio (GOR). The simulation results demonstrated the effectiveness of the developed ANN model in predicting the VMD process performance.

Summary: The presence of dyes in aquatic environments can harm aquatic life by inhibiting photosynthesis, decreasing dissolved oxygen levels, and altering the behavior and reproduction of aquatic organisms. Azo, phthalocyanine, and xanthene dyes are commonly used in industrial processes and frequently occur in water bodies. The toxic effects of dyes were discussed, with LC50 and EC50 values used for toxicity testing. Anaerobic membrane bioreactors (AnMBRs) have shown promise in removing dyes from water bodies, with hybrid AnMBRs and innovative designs being effective in achieving complete dye removal.

Summary: Anaerobic digestion (AD) is used to treat organic fraction of municipal solid waste (OFMSW). This study investigates the characteristics of biochar from digestate and its effects on AD performance. The biochar prepared at 700°C improves biogas production yields, shortens the lag time, and increases the chemical oxygen demand (COD) degradation rate. It also promotes acid conversion and enhances the biogas production performance. These findings suggest that biochar derived from digestate promotes biogas production and acid conversion in AD system.

Summary: This research investigated the decomposition of perfluorooctanoic acid (PFOA) using immobilized ZnO nanoparticles through electrophoretic deposition in photocatalysis and photoelectrocatalysis. ZnO nanoparticles show high potential for PFOA degradation due to their process performance, application under visible light exposure, and cost-effectiveness. The study found that the addition of peroxymonosulfate (PMS) could enhance PFOA photocatalytic decomposition over ZnO films, and both UV irradiation and visible light exposure were effective in initiating PFOA degradation. The research also demonstrated the excellent degradation performance of ZnO in photoelectrocatalysis, despite the potential ZnO corrosion caused by PMS.
