Patent number: 7338551Abstract: A device and method for generating micro bubbles in a liquid. The method includes the steps of: providing a flow-through channel containing at least two local constrictions of flow therein; passing the liquid at a velocity of at least at least 12 m/sec through a first local constriction of flow to create a first hydrodynamic cavitation field downstream from the first local constriction of flow; introducing a gas into the liquid in the first local constriction of flow, thereby creating gas-filled cavitation bubbles; collapsing the gas-filled cavitation bubbles formed in the first hydrodynamic cavitation field to dissolve the gas into the liquid, thereby forming a gas-saturated liquid; passing the gas-saturated liquid through a second local constriction of flow to create a second hydrodynamic cavitation field downstream from the second local constriction of flow; and extracting the dissolved gas from the gas-saturated liquid, thereby generating micro bubbles in the liquid.Type: GrantFiled: October 5, 2005Date of Patent: March 4, 2008Assignee: Five Star Technologies, Inc.Inventor: Oleg V.

Patent number: 7247244Abstract: Processes and devices associated with reducing the amount of organic substances in a fluid are described. In one example method, oxidizing agents may be introduced into a local constriction of flow in a flow-through chamber as the fluid is flowed therethrough. Cavitation bubbles which contain and/or are associated with the oxidizing agents may form. Collapse of the cavitation bubbles may produce pulses of ultraviolet light, thereby ionizing the oxidizing agents, producing hydroxyl radicals, and degrading and/or oxidizing the organic substances in the fluid. An example device may include a flow-through chamber including a local constriction of flow, a port configured to introduce oxidizing agents into the local constriction of flow, and may include an area configured to collapse the cavitation bubbles, thereby initiating events leading to degradation and/or oxidation of organic substances in a fluid flowed through the device.Type: GrantFiled: October 20, 2004Date of Patent: July 24, 2007Assignee: Five Star Technologies, Inc.Inventor: Oleg V.
