  • the present invention relates to method and apparatus for creating cavitation process within liquid fluids by means of flow through an apparatus containing rotating and stationary elements, with a gap between them through which a flow of a liquid passes through.
  • the method according to this invention consists of bringing a liquid to be processed in between two planar, round elements, one stationary one rotary, having regular, concentric structure of alternate protrusion and channels, divided into arched segments by radial channels in both planar elements, complementary on both stationary and rotary elements, so they create labyrinth like arrangement, with some clearance in both radial and axial directions, between the protrusions and channels which create said labyrinth, putting into motion the rotary element, catching liquid adhering to the rotating surfaces, creating difference of velocity of liquid flow within the circular spaces of said labyrinth, and consequently, creating the pressure difference along the channels of said labyrinth, where the pressure decreases in the direction of rotation, and increasing the velocity of the rotating element up to the point when the liquid pressure falls beyond the vapor point thus creating cavitation bubbles, and causing the liquid to flow in self-sucking manner or in assisted manner, the last, by adding an action of an auxiliary pump and intensifying the process cavitation .by pressing
