Recently, there is an increasing interest on organic solvent nanofiltration (OSN) for the separation and recovery of organic solvents due to the high energy consumption and the high cost involved in conventional organic solvent recovery processes. Conventional organic solvent recovery processes often involve, thermal phase separation processes such as distillation and deactivation which utilizes varying boiling points of organic solvents. Owing to such issues, pressure driven, membrane-based OSN process attracted significant attention as a low energy and low-cost alternative approach for the recovery of the organic solvents which utilizes the molecular size sieving effect via varying membrane pore sizes. However, the low solvent permeate flux, low stabilities of polymeric membranes under organic solvents and controlling the membrane properties suited for separation of various organic solvents/solutes has …
