Abstract: Membrane separation technology an d its applications in purifying and s eparating bioproducts were re-viewed.The pressure -driven membra ne processes discussed were microfiltration(MF ),ultrafiltration(UF),nanofiltration(NF),reverse osmosis(RO),which differ fromthe pore sizes.Their separation performances were characterizedbypermeatefluxandr ejection.Membraneseparationprocesses wereoftenoperatedinconcent ration and diafiltration modes and have bee n applied in the fractionation and pu rification of different proteins,s uch as whey protein,serumalbumin,egg whi te protein,Jojoba protein,recombi nant interleukin -2and some binary protein mixtures.

Key words: membrane separation, microfiltra tion, ultrafiltration, concentration, diafiltration
