Summary: This study introduces a highly effective FOTS-TiO2@SiO2 Nano fibrous membrane with super-amphiphobic properties for oil aerosol purification. The membrane is created by modifying the surface roughness of electrospun SiO2 membrane with TiO2 nanocones and then modifying the surface energy using FOTS. The membrane exhibits exceptional contact angles towards water and n-hexadecane, as well as low oil adhesion. It shows excellent oil aerosol separation performance with high filtration efficiency and low resistance, and it can be regenerated with higher efficiency compared to SiO2 membrane after multiple filtrations.

Summary: In this study, V2O5-WO3/TiO2@SiC catalytic membrane was prepared using TiO2 nanocones grown on SiC membrane as the support. The optimized VWTi(C-550)@SiC catalytic membrane exhibited superior NO removal efficiency (>90%) and stability during SO2 + H2O resistance and long-term tests. It also showed excellent dust filtration performance (>99.99% SiO2 particles interception rate). Moreover, the structure of nanocones effectively suppressed the fall of VWTi catalyst layer from the SiC surface during pulse-jet cleaning. Therefore, the optimized VWTi(C-550)@SiC catalytic membrane has great potential for simultaneous dust filtration and NH3-SCR denitration of medium-high temperature flue gas.

Summary: Due to the seriousness of offshore oil spills, research on oil-water separation has become increasingly important. In this study, a super-hydrophilic/underwater super-oleophobic membrane (BTA) was prepared by coating TiO2 nanoparticles on the surface of bacterial cellulose using poly-dopamine (PDA) and sodium alienate. The BTA membrane exhibited excellent underwater super-oleophobic property with a contact angle of approximately 153 degrees. It also demonstrated 99% separation efficiency and maintained excellent anti-pollution property after 20 cycles under ultraviolet light. The low cost, environmental friendliness, and good anti-fouling performance of BTA make it a promising solution for oily wastewater treatment.

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.
