A method for initiating cavitation within the fluid within a cavitation
chamber is provided. In the cavitation preparatory steps, a hydraulically
actuated piston is partially withdrawn and then the cavitation chamber is
isolated. Once the chamber is isolated, the hydraulic piston is further
withdrawn in order to form the desired cavities and then extended to
implode the cavities. At least one impeller, located within the
cavitation chamber, is rotated in order to stabilize the cavities.
