Abstract:
A method of making a liquid enriched with a free gas, comprising:providing a closed conproviding a quantity a liquid to a preselected level;providing a quantity of a pressurized gas to the container establishing a preselected pressure in the container;enriching the liquid in the container with the gas in the container using a mixing device to form a liquid enriched with a gas bonded to the liquid, wherein the enriching comprises:drawing off gas from an upper portion of the container;drawing off liquid from a lower portion of the container;combining the gas and liquid drawn off, and providing the combined gas and liquid to the mixing device;mixing the gas and liquid in the mixing device, wherein the mixing comprises first mixing the gas and liquid in a centrifugal pump to produce a gas/liquid mixture and then further mixing the gas/liquid mixture in a cyclone swirling chamber; andoutputting from the mixing device to the container, a liquid enriched with a gas bonded to the liquid; andproviding an abrupt pressure drop to the liquid enriched with a gas bonded to the liquid, thereby freeing gas bonded in the liquid and forming a liquid enriched with a free gas.
