The invention relates to an ultrasonic treatment device (1) for treating at least one component (3) immersed in a liquid treatment medium (2) by means of cavitation induced by pressure waves, with a receiving trough (4) which holds a liquid treatment medium (2) and which contains the liquid treatment medium (2) delimiting inner side (5) and an outer side (6) arranged on the opposite side and into which the at least one component (3) can be immersed in the liquid treatment medium (2), with ultrasound generating means (7), which are operatively connected to a sound-radiating surface (8) are arranged, with electrical control means (9) for supplying and / or controlling the ultrasound generating means (7) for generating pressure waves propagating in the liquid treatment medium (2) in order to transmit the at least one into the liquid treatment medium (2 ) immersed component (3) by means of cavitation induced by the pressure waves and with a sensor element (10) for at least indirectly detecting the cavitation induced in the liquid treatment medium (2).
