Experimental data are presented to show how imposed force fields can reduce flux decline during
the crossflow microfiltration of aqueous, mineral based suspensions. Both electric and ultrasonic
fields, employed individually or in combination, help prevent particle accumulation at the separating
surface. This allows fluid removal rates an order of magnitude higher than those obtained in
comparable tests without imposed force fields to be achieved. Such process intensification is
demonstrated to have the added benefits of lower overall power requirements, reduced pumping
requirements and smaller filtration areas.
