Summary: Ceramic membrane has sparked attention due to its cost-effectiveness. Microbial fuel cell-ceramic membrane bioreactor (MFC-CMBR) is considered an alternative technology for large-scale industrial applications. This study explores the electrochemical response and control of electricity utilization on ceramic membrane fouling in different types of MFCCMBRs. The experimental results show that coupling system with sludge acclimation and higher external resistance can effectively control membrane fouling. The coupling system improves the characteristics of sludge and alleviates membrane fouling.

Summary: The study on fouling dynamics of APAM towards AEM during ED reveals that monitoring the variation of the solution and membrane properties can help understand the fouling process. Deposition of APAM gradually hinders current transfer, leading to the formation of a gel layer and blockage of free volume, resulting in increased membrane resistance. Water splitting causes significant pH variation, altering the particle size of APAM and accelerating fouling formation.

Summary: Advancements in energy storage, photocatalysis, and sensors have generated large amounts of electrochemical impedance (EIS) data. Interpreting this data is challenging, but recent progress in machine learning (ML) models for EIS classification has been made. However, most models lack physical descriptor representation. In this study, variational autoencoders (VAE) were applied to EIS data analysis, achieving accurate classification, parameter prediction, and physical descriptor visualization.

Summary: Electrochemical impedance spectroscopy (EIS) is a valuable tool in membrane science and technology that provides information on the structure and functionality of the membrane. By studying multipore asymmetric membranes with conical pores, it was found that the ionic conduction properties can be modulated by adjusting the electrical interaction between charges on the pore surface and the nanoconfined ionic solution. The membrane's electrical response was found to be influenced by the amplitude and frequency of the external voltage signal, the electrolyte type and concentration, and the solution pH.

Summary: Previous studies have shown that vibration- or rotation-based techniques can effectively mitigate fouling during membrane filtration. However, it is difficult to incorporate these techniques with spiral wound modules (SWMs) widely used in water and wastewater treatment. This study developed a prototype membrane system to accommodate angular vibrations with a modified SWM, and experimental results showed that applying angular vibrations can effectively control algal fouling in an SWM with lower energy consumption compared to traditional methods.

Summary: Increasing temperatures worldwide pose a significant health risk, exacerbated by high humidity. Conventional air conditioners contribute heavily to carbon dioxide emissions, with dehumidification being a major factor. Membrane-based dehumidification system offers energy efficiency and non-toxic water vapor removal. This study demonstrates a membrane dehumidification system with polymeric hollow fibers coated with a green polyphenol coating, showing remarkable water vapor transport rate and selectivity. Long-term testing reveals minimal decline in vapor transport and a 4-5 times higher coefficient of performance (COP) compared to conventional dehumidifiers, making it a highly competitive, energy-saving device with reduced emissions and a smaller footprint.
