Abstract (en)
A method for introducing gas into water in excess quantity relative to an equilibrum condition corresponding to the saturation of water with the gas on any predetermined temperature and pressure, in which the water is intensively moved and circulated to form an intensive vortex which resembles to the form of the funnel of a tornado and the free surface of this funnel is exposed to the gas. The, circulation is mainatained for a while, at least as every water particle has entered and left the vortex 100 times. An apparatus for carrying out the method comprises a balloon-like conatainer (1), with a tapering lower part (4) and an oblique and tangential inlet duct (13) somewhat below the plane where the container (1) has it largest diameter. A feedback circulation path including a pump (14) and a resonator (15) is provided between the lower end of the container (1) and the duct (13). The resonator (15) forces the water flowing therethrough to rotate in a plane normal to the direction of flow. The so injected water forms a vortex in the container above which gas, preferably oxygen or carbon-dioxide is present which will be taken up by the water. The water made by the method comprises a gas in excess quantity relative to the equilibrum condition in such a way that the gas contained therein is in a stable and bound state.
