Patent ID: 7708453

Claim:
A device for creating hydrodynamic cavitation in fluid, the device comprising: a first fluid passage having a longitudinal axis and defined by at least one wall having an inner surface; a second fluid passage disposed within the first fluid passage and defined by at least one wall having an inner surface, the at least one wall that defines the second fluid passage includes a first baffle extending outward therefrom, thereby defining a first orifice between the first baffle and the at least one wall that defines the first fluid passage, the first orifice configured to generate a first hydrodynamic cavitation field downstream therefrom, wherein the at least one wall that defines the second fluid passage includes one or more openings to permit fluid to flow from within the first fluid passage to within the second fluid passage or vice versa; a second baffle disposed within the second fluid passage and spaced from the inner surface of the at least one wall that defines the second fluid passage, thereby defining a second orifice between the second baffle and the at least one wall that defines the second fluid passage, the second orifice configured to generate a second hydrodynamic cavitation field downstream therefrom.
