Recent progress of organic solvent nanofiltration membranes

Solvent separations present one of the largest opportunities for membrane technologies. Currently, industries use millions tons solvents manufacture drugs, oils and chemicals. Multiple purifications must be conducted in order to purify products from solvents. However, existing separation processes are energy-intensive. Organic solvent nanofiltration (OSN) or solvent-resistant has emerged as an energy-efficient alternative processes. We have summarized recent advances fabrication state-of-the-art polymeric membranes including integrally skinned asymmetric membranes, thin film composite nanocomposite this review. The performances OSN continue push boundary terms high permeances rejections various solutes. advancements been achieved through novel materials innovative methods. also discussed future outlook pointed out potential areas further research exploration.
