Introduction
A supersonic wave means a wave higher than audio frequency and generally stands for a frequency more than 16 KHz.
Once the supersonic wave is launched in solvent, expansion and contraction occur in the liquid by the vibration of molecules and, when the energy of the supersonic wave becomes larger, the cohesive power of the liquid is destroyed and millions of tiny cavities are created. This is called CAVITATION.
Powerful energy is created through the explosion of these cavities. By this powerful shock wave, cleaning from the surface of the object to deep inside is performed...
