Summary: This study developed a chlorine-resistant polyamide (PA) reverse osmosis (RO) membrane by introducing p-amino diphenylamine (p-ADA) onto the membrane surface. The modified membranes showed improved resistance to chlorine and the capability of regeneration. The introduction of p-ADA increased the resistance of NaCl transmembrane without sacrificing membrane permeance, and provided protection to the membrane from direct attack by free chlorine.

Summary: In this study, highly stable antifouling NF membranes with chlorine resistance were successfully fabricated by incorporating 2-aminophenol-4-sulfonamide (APSA) to form the polyamide-sulfonamide active layer. The results showed that APSA was successfully grafted on the membrane surface, resulting in a smooth membrane surface and decreased water contact angle. The PA-SA NF membranes exhibited high flux recovery rates for various contaminants and maintained stable rejection and water flux even after chlorination. This work provides a feasible strategy for the development of NF membranes with highly stable antifouling property and chlorine resistance.

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.
