Summary: This study evaluated the performance of commercial-grade CHA and T-type membranes, as well as NaA zeolite membrane, for the dehydration of ethanol. The CHA sample exhibited the highest water permeance and selectivity, while the NaA membrane had slightly lower performance and the T-type membrane had the lowest permeance and selectivity. Performance declined over time, particularly for the NaA membrane. The results of this study are important for the design of solvent dehydration systems.

Summary: This study investigates the influence of xylene activity on the vapor and liquid permeation/separation performance of b-oriented MFI zeolite membranes. The results showed that the permeance and separation factor increase with temperature, but decrease with increasing xylene activity. B-oriented MFI zeolite membranes exhibit better vapor permeation/separation performance compared to randomly oriented membranes, and show less negative effect of xylene activity on separation factor. However, both types of membranes show poor separation factor when operated in the pervaporation mode.

Summary: Membrane-based technology is attracting attention due to its low energy consumption, mild operating conditions, and high efficiency. Polymeric membranes are widely used for their low cost and reproducible preparation, but face issues like fouling and trade-off between permeability and selectivity. Inorganic membranes like zeolite membranes, with their hydrophilic nature, high stability, permeability, and selectivity, offer solutions to these problems. Their molecular-level pore size and adsorption property make them suitable for a variety of separation processes, although challenges like reproducibility, defects, and high manufacturing costs still hinder their industrial-scale application.

Summary: This study synthesized compact X-type zeolite membranes with excellent separation performance using the in-situ heating method in hetero-alkali-metal cation synthesis solutions. The hetero-alkali-metal cations distorted the crystal structure and regulated the rates of crystal nucleation and growth, leading to the formation of compact zeolite membranes. This method provides a new approach for designing defect-free membranes with high permselectivity.

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.
