Summary: Research and development towards sustainable chemistry involves the development of new materials and exploration of new fabrication methods. In this study, composite membranes made from biodegradable cellulose were fabricated using a simple and scalable process. The use of dimethylsulfoxide as impregnation liquid improved the membrane separation performance and lamination strength. The thickness of the barrier layer could be reduced to a few micrometers, and the membrane performance could be adjusted by varying the cellulose concentration and co-solvent fraction. The cellulose-cellulose composite membranes showed potential as a sustainable alternative material for various separations.

Summary: Emissions from the ceramic industry cause pollution to water bodies due to organic compounds, heavy metals, and chemicals. The effluent must be treated before discharge, and laws control the chemical oxygen demand. Membrane technologies offer advantages over conventional methods, with nanofiltration using ceramic membranes showing promise in reducing COD levels. Multi-stage filtration with various membrane combinations can effectively lower COD levels and increase operating time.

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.
