ABSTRACT:
The invention utilizes multiple frequency megasonic generators driving multiple frequency harmonic transducers. Generator signals that increase cavitation efficiency and that have successive time periods with predominantly stable cavitation and predominantly transient cavitation further improve the performance of the cleaning, microbiological inactivation, sonochemistry or processing systems. Probes that monitor the megasonics and feedback the information to the generator provide consistency of process.
