Hydrodynamic cavitation system for the removal of unwanted, toxic, or contaminated organic and inorganic compounds
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.
