Design and function
3.3 Function
The device uses cavitation triggered by low-frequency ultrasound. Piezoelectric oscillating
systems are located on the underside of the oscillating tank. The ultrasound generates
strong pressure fluctuations in the sonication fluid. Cavitation bubbles are formed
at the pressure minima. At higher ambient pressure around the bubbles, they collapse
very quickly. This results in strong local microcurrents on the surfaces of the objects being
treated. This removes dirt from the surface of the objects. Dirt particles are removed
and fresh sonication fluid flows in.
