Summary: This study proposes a new method for fabricating loose nanofiltration (LNF) membranes by combining co-extrusion technology and chemical cross-linking. The prepared membranes exhibit small pore size, strong positive charge, high rejection of various dyes, and low salt rejection. They also show excellent stability during long-term filtration and good fouling reduction properties against bovine serum albumin (BSA) and lysozyme (LYZ). This research provides new perspectives for the design of useful LNF HFMs for the treatment of dye/salt wastewater mixtures.

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.
