The effects of crossflow velocity and concentration of pectin on the retentive microfiltration by a titania microfiltration membrane with pectinase physically immobilized on it by a dynamic formation method were investigated to examine the potential of these reactive membranes in applications involving solutions containing pectin. The permeability of the titania membrane with approximately 5 g/m 2 immobilized pectinase was significantly larger than the permeability of a control membrane without immobilized pectinase in pectin concentration experiments from 0.4 to 2.6% at crossflow velocities in the range 0.8−2.6 m/s. The permeability increased with crossflow velocity and decreased with pectin concentration.
