Improved Organic Solvent Nanofiltration (OSN)
By increasing the membrane-solvent affinity, solvent fluxes as well as solute retentions can be substantially increased. Ceramic membranes are stable in solvent environments. However, their strong polar surface strongly limits the number of applications in OSN.
The grafting by A-membranes tunes the membrane-solvent interaction to all kinds of solvent processes: solvent cleaning and recovery, catalyst recovery out of solvents, isolation of active pharmaceutical ingredients…
