Fouling mechanisms of phenolic compounds in fruit juices during nanofiltration (NF) are complex and unclear.This study was to evaluate the effects of some operating parameters on fouling resistances during NF of phenolic compounds with two different membranes.Two commercial NF membranes,VNF1 and VNF2,were used in this study.Performances of six typical phenolic compounds in fruit juices,including gallic acid,protocatechuate,caffeic acid,chlorogenic acid,ferulic acid and rutin during NF process were investigated.Experiments were carried out under transmembrane pressures (TMPs) of 2,4,6,8 bar and concentrations of 1,2,4 g/L,respectively.
