An aerating system for treating a waste lagoon or some type of wastewater that captures and recirculates air that has been previously pumped into the lagoon via a skirt. The system also utilizes an oxygen source to pump oxygen into the waste lagoon or wastewater that can also be recirculated. A manifold of the system is designed to have intakes for both the recirculated air and for the oxygen source.

A mixing device includes a mixing section that mixes a first liquid-phase fluid with one kind or two or more kinds among a solid, a gas, and a second liquid-phase fluid different from the first liquid-phase fluid, in which the mixing section includes a supply hole for a fluid, a discharge hole for the fluid, a flow path that makes the supply hole and the discharge hole communicate with each other, and pins that protrude from the mixing section such that a fluid that includes materials to be mixed is supplied from the supply hole to the flow path, mixed by passing through the flow path with contact with the pins, and discharged from the discharge hole.

A wine aerating device for adding oxygen containing gas into wine, the device comprising a gas cylinder containing pressurised gas which contains more than 21% oxygen by volume when measured at atmospheric conditions, a tube with a first end in fluid communication with the gas cylinder to a membrane which is in fluid communication with a second end of the tube, wherein the membrane is insertable through the neck of a wine bottle so that, in use, oxygen gas diffuses via the membrane into the wine, wherein the said membrane has a pore size of 0.1 m to 10 m, preferably 1 m to 10 m.

Gaseous nanobubbles are created and infused into the blood stream to therapeutic effect such as oxygenation. The nanobubbles may be created inside or outside of the patient, either during infusion or prior to infusion. CO2 is extracted from the blood to improve oxygen.

A nutrient system includes at least one nutrient feed line for introducing at least one nutrient into a water inlet or supply to form a circulation stream: an eductor injector for introducing a powder comprising at least one dry nutrient into the circulation stream; an ultrasonic cavitation reactor for applying at least one frequency to the circulation stream; and a nanobubble generator module for introducing nanobubbles of at least one gas into the circulation stream. The system may also include a cooling/ultraviolet disinfection module for cooling and disinfecting the circulation stream. The system may be used to obtain a nutrient composition for a plant growing environment.

A system for performing a gas-liquid mass transfer includes a container bounding a compartment and having a top wall, a bottom wall, and an encircling sidewall extending therebetween. A first opening is formed on the container so as to communicate with the compartment. A liquid is disposed within the compartment and having a top surface disposed below the first opening. A gas is blown through the first opening so that the gas passes over at least a portion of the top surface of the liquid, the gas producing turbulence on the top surface of the liquid that is sufficient to produce a mass transfer between the gas and the liquid. A mixing element is disposed within the compartment.

Disclosed are a system and a method for dissolving water-soluble gas such as oxygen into water, employing microporous membrane.

A method for producing stabilized, gas-infused liquids containing ultra high concentrations of infused gas, includes steps of: generating a gas-infused liquid in a sealed vessel under a high pressure of at least 20 psi; stabilizing the gas-infused liquid by passing the liquid while still under the high pressure through a tubular flow path arrangement which compresses the infused gas into nano bubbles in the liquid; infusing an additional amount of the gas into the stabilized liquid by injecting the same, while still under high pressure, back into the sealed pressure vessel along with more of the gas; and again stabilizing the liquid by again passing liquid, while still under the high pressure, through the tubular flow path arrangement to thereby form the additional amount of infused gas into nano bubbles in the liquid.

[Summary]

This invention is about Nano Bubble and Hydroxyl Radical Generator and has the following detail features; Air inlet part; Inlet pipe for inflowing liquid connected to the above air inlet part; Pump connected to the above inlet pipe; Drive motor connected to the above pump; Rotating blade connected to drive axis of the above drive motor; Fixed blade connected to inside wall of the above pump, and arranged between the above rotating blade; The above rotating blade, the fixed blade or cylindrical blade surfaces of both blades are slanted in a direction.

Therefore, this invention proposes Nano Bubble and Hydroxyl Radical Generator which increases dissolving rate of gas by accelerating finization and mix of air and liquid through inducing turbulence of air and liquid by way of constructing slant on surfaces of each blade.
