Summary: Surface-modified silver nanoparticles with different functional groups were synthesized and used as functional fillers in nanocomposite membranes for membrane bioreactors (MBRs). The modifications successfully immobilized the nanoparticles inside the membrane, reducing silver release. The modified nanoparticles exhibited enhanced antimicrobial activity and improved the antifouling properties of the membranes. This led to significant improvements in MBR performance, with increased flux, COD removal, and flux recovery.

Summary: The study characterized a community of purple phototrophic bacteria (PPB) enriched from municipal wastewater to assess their growth, tolerance, composition, and potential for resource recovery from NH4+-rich medium. The results showed that PPBs demonstrated remarkable tolerance to high concentrations of NH4+-N and acetate, with the potential for growth and protein accumulation even at elevated levels of these compounds. This suggests that PPBs have promising applications for resource recovery from NH4+-rich wastewater.

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.
