Abstract
An acoustic liquid processing device in the form of a vessel having an interior wall which surround a process liquid. An electrostatic film transducer is attached to the interior wall to substantially envelop a selected volume of the process liquid. The transducer's acoustic impedance is approximately equal to that of the process liquid. The transducer is energized to subject the process liquid to acoustic vibration.
