Advanced rotational hydrodynamic cavitation system for the irreversible removal of bacteria, pathogens, viruses, and chemical bonds
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.
