ABSTRACT:
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.
