WAKEMAN, R.J. and TARLETON, E.S., 1993. Utilising particle-liquid interfacial phenomena to augment crossflow microfiltration. Proceedings of the 1993 IChemE Research Event, January, Birmingham, pp. 537-539.
Results from an experimental study of field assisted crossflow microfiltration are presented. Both
electric and ultrasonic fields, either in isolation or in combination, can reduce membrane fouling by
utilising particle-liquid interfacial phenomena. Synergistic effects were observed when the fields
were applied simultaneously. Lower crossflow velocities can be utilised when force fields are
employed, implying that pumping costs, heat transfer in recirculation loops, and the degradation of
shear sensitive streams can be substantially reduced.
