Abstract: A hydrodynamic cavitation system features a first stator, a second stator, a third stator, and a rotor, each having a plurality of indentations. The hydrodynamic cavitation system further includes a drive shaft, a variable speed motor, and a pump, wherein the pump circulates fluid through the hydrodynamic cavitation system while the drive shaft actuates the rotor, generating hydrodynamic cavitation between each stator and the rotor. Each of the plurality of indentations provides different regions to optimize overall hydrodynamic cavitation volume, increasing cavitation locations, which can coalesce to become a macro cavitation site and cavitation cloud. The hydrodynamic cavitation system removes bacteria, pathogens, viruses, fungi, cyanobacteria as well as breaks chemical bonds, effectively treating contaminated water and other fluids.

Abstract: An advanced hydrodynamic cavitation system includes a housing, a first stator with angled ridges, a second stator that is circular with angled ridges, a rotor having rotor blades housed within the second stator, and a driveshaft, and is configured to work with a motor, a pump, and oxidizing agents such as hydrogen peroxide or ozone to form free radicals. Hydrodynamic cavitation occurs (1) on the leading edge of the rotor blades; (2) in the constriction between the rotor blades, depending on the design; (3) in the gap between the first stator and the rotor blades; and (4) in the gap between the second stator and the rotor blades. The four cavitation regions may coalesce to become a steady-state supercavitation cloud that removes unwanted, toxic or contaminated organic and inorganic compounds, specifically with the ability to treat and decontaminate sludge, wastewater, ballast water, drinking water, harmful algal blooms, and biomedical waste.
