Abstract
A method is taught for debubbling a liquid composition containing entrained gas bubbles that increases the effectiveness of ultrasonic debubbling apparatus employed. The method comprises the steps of immersing an ultrasonic horn in water, the horn being contained within a vessel and coupled to a pair of transducers; adjusting an RF generator connected to the pair of transducers to produce a signal at or near a parallel resonance frequency of the pair of transducers; fixing the RF generator at a constant voltage level; and flowing the liquid composition to be debubbled through the vessel with the RF generator operating at constant voltage level and at a variable operating power level that varies with the viscosity of the liquid composition.
