Summary: A high-efficiency alpha-alumina ultrafiltration membrane was fabricated through co-sintering a gel layer with a pre-sintered interlayer. The use of a pre-sintered interlayer with rigidity and low roughness facilitated the preparation of a defect-free and ultra-thin separation layer. The prepared alpha-alumina ultrafiltration membrane had a thickness of only 140 nm, pure water permeability of 230 L m-2h-1 bar-1, and an average pore size of approximately 7 nm. It exhibited high rejection rates (>99%) and permeabilities (60-212 L m-2h-1 bar-1) in the separation of polyvinyl alcohol wastewater and the removal of Congo red dye, respectively.

Summary: The use of nanomaterials in polymeric composite membranes has the potential to improve separation performance. However, the dispersion and stability of these nanomaterials have been major issues for commercial applications. In this study, zinc oxide powders were blended into polyvinyl chloride ultrafiltration membranes, resulting in improved membrane microstructure, separation performance, and bulk properties. The membranes with 0.05% weight MicNo (R) platelets had higher water flux and enhanced antifouling properties compared to pristine PVC and commercial ZnO-doped membranes.

Summary: This study proposes a novel heat-activated peroxydisulfate (heat/PDS) process for cleaning membrane fouling caused by humic acid (HA). The combination of heat and PDS can achieve almost 100% recovery of permeate flux by changing the HA structure and enhancing foulant detachment from membranes. The properties of treated membranes are characterized, and the results demonstrate the effective removal of reversible and irreversible foulants by heat/PDS cleaning. The heat/PDS method shows comparable performance to NaClO in membrane cleaning and provides high performance in removing fouling caused by different substances, suggesting its potential as an alternative for practical membrane cleaning.

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.
