Abstract
An advanced hydrodynamic cavitation device formed from a cylindrical tube having a flow through chamber. The chamber has a series of stages with each stage formed from at least three plates spaced annularly and extending radially inward at an oblique angle with respect to the longitudinal axis of the flow through chamber. Each plate has shear inducing side edges and a plurality of orifices with shear inducing edges. The orifices are arranged perpendicular to the plates and shaped to control the velocity of the fluid. An unrestricted passageway exists along the central axis of the flow through chamber to provide a constant flow for continuous flushing of suspended solids to prevent clogging. Additionally, the passageway will facilitate the insertion of a pressure cleaning tube without requiring that the device be disassembled.
