What is claimed is: 1. A method for processing a fluidic mixture in a multi-stage hydrodynamic cavitation device, comprising the steps of: providing a flowpath through the hydrodynamic cavitation device; pumping the fluidic mixture through a multi-jet nozzle having a plurality of channels, wherein the multi-jet nozzle creates cavitation features in the fluidic mixture; passing the fluidic mixture over a plurality of spiral guides disposed in a working chamber, wherein the spiral guides create cavitation features in the fluidic mixture; conveying the fluidic mixture over a plurality of flow guides in a vortex chamber, wherein the flow guides and vortex chamber create cavitational features in the fluidic mixture; and introducing the fluidic mixture to an atomizing cone which has an increasing cross-sectional area, wherein the fluidic mixture loses all cavitational features. 2. The method of claim 1, wherein the working chamber is bounded by an outer wall of a guide cone and an inner wall of a convergent cone arranged coaxially along the flowpath with the guide cone such that the working chamber has a decreasing diameter along the flowpath. 3. The method of claim 2, wherein the spiral guides are arranged about the outer wall of the guide cone and have a decreasing pitch following the decreasing diameter toward a peak of the guide cone. 4. The method of claim 1, wherein the multi-jet nozzle includes four channels, said channels having abrupt contractions and expansions along the flowpath. 5. The method of claim 1, wherein the multi-jet nozzle includes four channels, said channels being venturi-type channel comprised of a conical inlet having a round profile, a cylindrical throat and a conical outlet. 6. The method of claim 1, further comprising the step of processing the fluidic mixture multiple times by multiple passage through the multi-stage hydrodynamic cavitation device or passage through multiple multi-stage hydrodynamic cavitation devices arranged in series. 7.

The multi-stage hydrodynamic cavitation device of claim 7, wherein the multi-jet nozzle has four channels and each channel has an abrupt contraction and an abrupt expansion along the flowpath. 9. The multi-stage hydrodynamic cavitation device of claim 7, wherein the multi-jet nozzle has four channels and each channel is a venturi-type channel comprised of a conical inlet having a round profile, a cylindrical throat and a conical outlet. 10. The multi-stage hydrodynamic cavitation device of claim 7, wherein the generally annular-conical shape of the working chamber is defined by an outer wall of a guide cone and an inner wall of a convergent cone arranged coaxially along the flowpath with the guide cone. 11. The multi-stage hydrodynamic cavitation device of claim 10, wherein the spiral guides are arranged about the outer wall of the guide cone and have a decreasing pitch following the decreasing diameter toward a peak of the guide cone. 12.
