Summary: This study investigates the use of nanofiltration for separating saccharides from phenolics and compares the permeation of different sugars in a plant hydrolysate with a model sugar solution. The results show that diafiltration mode provides suitable conditions for sugar diffusion and prevents deposition and fouling. The purification of phenolics occurs step by step, with initial purification from galactose and mannose, followed by purification from disaccharides. The purification factors achieved in diafiltration mode are higher than in concentration mode.

Summary: This study used NF270 nanofiltration membranes and SDS-stabilized hexadecane to investigate the membrane fouling mechanisms by highly saline oil-water emulsions. The research found that oil caused a sudden decrease in permeate flux only for more saline feeds, and over the longer term, the additional hydraulic resistance due to a layer of oil droplets on the membrane surface became the dominant fouling mechanism.

Summary: A thin-film nanocomposite (TFN) NF membrane with high rejection, improved water permeability, and antibacterial activity was developed for sulfate separation in concentrated seawater. The membrane was modified by N-doped graphene quantum dots, dopamine, and piperazine, which enhanced the nanostructure of the active polyamide layer. The TFN-NF membrane exhibited promising performance in high-salinity solution separation, making it a potential candidate for practical application.

Summary: This study utilized a validated CFD model to investigate the suppression of concentration polarization (CP) by patterned membranes during nanofiltration. Results showed that microstructured membranes had a significant effect on controlling CP evolution by disturbing the flow field near the microstructures. The concentration accumulation on the patterned surface was reduced by 10-12% compared to the flat membrane, and the cambered membrane performed better than the triangular membrane in terms of CP suppression.

Summary: Membranes offer a scalable and cost-effective approach to ion separations for lithium recovery. The impact of pH and feed salinity on nanofiltration's selectivity in salt-lake brines is uncertain. By analyzing experimental and computational data, we found that acid-pretreated feed solutions can enhance the Li+/Mg2+ selectivity of polyamide membranes by 13 times. The appropriate Cl-/SO42- molar ratios in feed solutions can improve predictions of ion rejection and Li+/Mg2+ separation factors by up to 80%.

Summary: This study compares the pervaporative concentration of dairy solutions with ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO). The results show that pervaporation exhibits almost complete retention of dairy solids and has a lower flux decline compared to other membrane processes. Unlike UF, NF, and RO, the mass transport in pervaporation is mainly determined by the membrane itself rather than external factors such as membrane fouling and concentration polarization.

Summary: This study presents a simple and versatile method to prepare novel polyamide nanofiltration membranes via a hydrogel-assisted interfacial polymerization process. The diffusion of piperazine was precisely controlled by adjusting the hydrogel composition and crosslinking degree, resulting in the formation of a thin film composite membrane with improved water permeance and Na2SO4 rejection due to the synergistic effect of decreased thickness and improved surface hydrophilicity.

Summary: The study found that Lewis acid AlCl3 is effective in catalyzing the conversion of sucrose to HMF, and combining it with different Bronsted acids or changing the Lewis acid/Bronsted acid ratio can shorten the time required to reach maximum HMF yield. In the green reaction media of GVL solvent, sucrose conversion resulted in comparable HMF yields to the DSMO-water system. The addition of NaCl and Na2SO4 had opposite effects on HMF production.

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.
