Summary: Pervaporation is a low-energy membrane separation technology commonly used for desalination, where the use of traditional polyvinyl alcohol (PVA) membranes can be limited by long cross-linking durations or high temperatures. By using a photo-crosslinkable polymer PVA-SBQ, high water fluxes and efficient desalination performance can be achieved.

Summary: Thin film composite (TFC) membranes with polyvinyl alcohol (PVA) selective layer and polyacrylonitrile membrane-support were developed using dynamic mode technique. The effects of various factors on the gel layer formation and pervaporation (PV) performance of TFC membranes were studied. The results showed that PVA concentration, filtration time, and transmembrane pressure (TMP) influenced the thickness of the selective layer and the pervaporation permeate flux. By optimizing the conditions, TFC membranes with high performance were successfully prepared.

Summary: In this study, a long alkyl chain-containing organosilica layer was utilized to modify silicalite-1 membranes, resulting in bi-layered BTESO/silicalite-1 composite membranes. After BTESO modification, the surface of the membranes became smoother, denser, and more hydrophobic. The modified membranes exhibited good separation performance in pervaporation, with increased ethanol flux and reduced water flux without sacrificing ethanol flux.

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.
