ABSTRACT:
A method for processing a fluidic mixture in a multi-stage hydrodynamic cavitation device is disclosed. The fluidic mixture is introduced to an inlet and passed through a flowpath having at least ten cavitation zones. The fluidic mixture is exposed to cavitation inducing features in each of the at least ten cavitation zones to induce cavitation bubbles, which bubbles are then collapsed between every two adjacent of the at least ten cavitation zones. The multi-stage hydrodynamic cavitation device for processing the fluidic mixture has a generally cylindrical housing with an inlet, an outlet, a flowpath therebetween, and a plurality of cavitation zones along the flowpath. Two or more of the cavitation zones along the flowpath comprise a disk multi-jet nozzle having a plurality of through channels disposed across the surface thereof, wherein each channel includes expansions and contractions of its cross-sectional area along its length.
