By homogeneously mixing a plurality of fluids, when mixing a gas with a liquid, it is possible to mix a large amount of gas into the liquid, so that large bubbles are not generated, and fine bubbles (in some cases, fine bubbles including microbubbles or ultra-fine bubbles) can be mixed into the liquid. A fluid mixing output apparatus of the present disclosure includes a housing and an internal structure accommodated in the housing. The housing is provided with a plurality of fluid supply ports for supplying at least a first fluid and a second fluid and a fluid outlet at its downstream end for outputting a plurality of fluids after mixing the plurality of fluids. The internal structure includes a first portion, a second portion, a third portion, and a fourth portion. The first portion includes a shaft portion and a vane spirally formed to generate a swirling flow in a fluid. The second portion is located downstream from the first portion, and includes a shaft portion and a plurality of protrusions protruding from an outer circumferential surface of the shaft portion. The third portion is located downstream from the second portion, and includes a shaft portion and a vane spirally formed to generate a swirling flow in a fluid. The fourth portion is located downstream from the third portion, and includes a shaft portion and a plurality of protrusions protruding from an outer circumferential surface of the shaft portion. One of the plurality of fluid supply ports of the housing is formed in a portion corresponding to the vane of the third portion, and the second fluid is supplied to the third portion and supplied to the fourth portion as a swirling flow while being mixed with the first fluid.

The invention relates to a method for rearing animals and in particular poultry or pigs that comprises supplying the animals with drinking water in order to water the animals, injecting oxygen and CO.sub.2 into the drinking water, before the drinking water reaches the animals, according to one of the following modes: two injections, one of CO.sub.2 and one of oxygen, are carried out simultaneously into the drinking water, or one injection, a mixture of oxygen and CO.sub.2, is carried out into the drinking water.

[Problem]

A preparation of forming bubbles of carbon dioxide gas which is put into a micro-bubble generator is realized, unlike a conventional tablet, as a tablet which can retain an ability to neutralize and remove completely chlorine contained in tap water from start of dissolution of the tablet inside the micro-bubble generator to the completion of dissolution thereof, thereby providing a method for producing micro-bubbles of carbon dioxide gas by using the tablet and a device thereof.

[Solution]

There is provided a method for producing carbon dioxide gas/micro-bubbles mixed water in which a carbonated bathing agent is a tablet which is 7 mm or more both in tablet diameter and tablet thickness, 15 kg or more in tablet hardness, 10 wt % or less in tablet friability and from 5.5 to 9.0 in pH immediately after dissolution of the tablet in hot water and the carbonated bathing agent contains at least one of the following body rendering agents and contains at least one of the following chlorine neutralizing compounds.

A method and apparatus for significantly extending the shelf life of an inert gas infused fluid. Air that has been subjected to a high electrical potential corona and then mixed with a fluid in a constant differential pressure venturi is delivered to an improved container apparatus wherein an inert gas is infused into the fluid such that the resultant stabilized fluid demonstrates significantly improved usable life. Alternatively, an additive may be combined to provide application specific characteristics. The combination of the method and apparatus, taken together, provide substantially increased shelf life of an inert gas infused fluid.

The invention provides methods and compositions for carbonation of cement mixes using pressurized carbon dioxide delivered to the mix.

The present invention relates to hydrogencarbonate water and a cleaning method using the hydrogencarbonate water. Provided are hydrogencarbonate water obtained by dissolving carbon dioxide in hydrogen water having a dissolved hydrogen concentration of 0.1 ppm to 2.0 ppm; and a cleaning method comprising cleaning a substrate by immersing the substrate in the hydrogencarbonate water, or spraying the hydrogencarbonate water to the substrate.

A method for forming a solution of ammonium carbamate is provided herein. The method includes, but is not limited to, providing a reactor comprising a solution of ammonia. The method further includes, but is not limited to, feeding carbon dioxide through the solution of ammonia to form a mixture. The method further includes, but is not limited to, combining a solution of sodium hydroxide and the mixture to form the ammonium carbamate.

A bag assembly for use with a heat exchanger includes a flexible bag having of one or more sheets of polymeric material, the bag having a first end that bounds a first compartment and an opposing second end that bounds a second compartment, a support structure being disposed between the first compartment and the second compartment so that the first compartment is separated and isolated from the second compartment. A first inlet port, a first outlet port, and a first drain port are coupled with the flexible bag so as to communicate with the first compartment. A second inlet port, a second outlet port, and a second drain port are coupled with the flexible bag so as to communicate with the second compartment.

A nanobubbler includes a porous ceramic material, a first inlet configured to inject a gas into the porous ceramic material, wherein the porous ceramic material is configured to emit nanobubbles into the chamber from the surface in response to the injection of the gas, a chamber positioned adjacent to a surface of the porous ceramic material, a second inlet configured to inject a liquid into the chamber so that the nanobubbles are dislodged from the surface of the porous ceramic material into the liquid, and an outlet configured to output from the chamber the liquid infused with the nanobubbles. The nanobubbles infused into the liquid have an average diameter of less than 500 nanometers.
