An experimental study of field assisted crossflow filtration has shown that electric and ultrasonic
fields, either in isolation or in combination, reduce membrane fouling. Particle liquid interfacial
phenomena are used to advantage with the imposed fields to remove fouling layers and enhance
flux rates. Synergistic effects were observed when the fields were applied simultaneously. Lower
crossflow velocities can be utilised which implies that pumping costs, heat transfer in recirculation
loops, and the degradation of shear sensitive streams can be reduced.
