Summary: One important way to promote carbon reduction in the environmental industry is to promote resource recycling. Membrane separation technology has advantages in resource recovery and advanced treatment of industrial wastewater. However, traditional organic membranes face challenges such as poor organic solvent tolerance, lack of oxidation resistance, and membrane fouling control. The emerging graphene oxide (GO)-based membrane with improved characteristics shows great potential in industrial wastewater treatment.

Summary: Textile production is a major contributor to global freshwater consumption and wastewater generation. The use of thousands of chemicals in textile wet-processing poses environmental and health risks, particularly in countries like India. The high salt concentration and complexity of textile wastewater make it difficult to treat using current technologies. Therefore, there is a critical need for the development of efficient treatment technologies, as well as improved methods for evaluating water quality.

Summary: Dyes, solvents, heavy metals, and oils pose a significant threat to water supplies globally. Advanced research has led to the development of green-adsorptive membranes that offer simple operation, high separation efficiency, low energy consumption, eco-friendliness, and affordability for water treatment. Nanocellulose, with its exceptional properties such as large specific surface area, anti-fouling behavior, high aspect ratio, and biodegradability, has been extensively studied as an excellent biomaterial in membrane filtration. The modification of nanocellulose has also shown promise in enhancing the performance of filtration membranes for heavy metal removal, oily water separation, and dye extraction.
