Systems and methods for creating an oxidation reduction potential (ORP) in water for pathogenic control are described. The systems and methods generate an oxidation reduction potential that provides pathogenic control of the solution as well as pathogenic control of the surfaces with which the solution comes in immediate contact. The system also provides purified drinking water to a tap or an ice making machine.

An apparatus is provided having a heat generation device such as a boiler. A hypersonic energy harvester is provided having a first input and a second input. The first input and the second input are fluidly coupled to the heat generation device. A variable speed pump is fluidly coupled to supply liquid from the heat generation device to the hypersonic energy harvester. A deaerator is fluidly coupled to receive condensate from the hypersonic energy harvester.

An apparatus for dissolving gas into a liquid, comprising a housing with an inlet opening for the liquid and an outlet opening for the liquid, and a blade unit arranged inside the housing in a small cross section area between the inlet opening and the outlet opening, wherein a flow cross section for the liquid at the small cross section area is smaller than at the inlet opening, further comprising a gas inlet provided at an outside of the housing and at least one gas outlet provided in the housing on a surface of the blade unit, the at least one gas outlet being connected to the gas inlet by means of a channel, and to a method for producing such an apparatus and an use of such an apparatus.

This application relates to a fluid mixing device including a nozzle having a converging chamber, a chemical injection port, a diverging chamber, a nozzle throat, and an adjustable self-opening valve.

A gas mixer for mixing a first gas and a second gas, having a first, outer gas housing part, having an inlet for the first gas in a longitudinal axis and an inlet for the second gas in a transverse axis, a second, interior gas housing part set into the first gas housing part to form an annular space for a second gas, having a mixing space into which the first gas and the second gas are introduced for mixing. The first and second gas housing parts and the annular space are aligned along the longitudinal axis and the mixing space is aligned cylindrically along the longitudinal axis. A mixing device having a plurality of hollow rods is arranged in the mixing space. A hollow space of a hollow rod is in fluid communication on both sides with the annular space. The number of hollow rods extends transverse to the longitudinal axis and the transverse axis and at least one hollow rod has a plurality of openings for the second gas, so that the hollow space is in fluid communication with the cylindrical mixing space.

In a device for infusing a gas from a gas source into a liquid beverage, a beverage container defines an interior for holding the liquid beverage therein. A venturi mixing device has a liquid inlet port in fluid communication with the beverage container, a gas inlet port in fluid communication with the gas source and a discharge port. The venturi mixing device is configured to infuse the gas received from the gas source into liquid beverage received from the beverage container. A faucet is in fluid communication with the discharge port of the venturi mixing device and is configured to dispense the liquid beverage infused with the gas.

Initial liquid containing fine bubbles is produced by mixing water and air (step S11). Fine bubbles have diameters of less than 1 μm. The density of bubbles in the initial liquid is measured (step S13), and when the measured density is less than a target density (step S14), the initial liquid is heated and reduced in pressure so that the liquid is vaporized (step S15). As a volume of the liquid decreases, the density of fine bubbles increases, and high-density fine bubble-containing liquid is easily obtained. Alternatively, by increasing the density of fine bubbles in the initial liquid with using a filter that does not pass all fine bubbles, high-density fine bubble-containing liquid is easily acquired (step S15). When the density of bubbles in the initial liquid is greater than the target density, the initial liquid is diluted (step S16).

A fluid mixing apparatus includes mixing conduits that extend through a fluid plenum. The fluid plenum, which surrounds a first wall defining a main passage fluidly coupled to a low-pressure fluid source, is surrounded itself by a second wall defining a high-pressure plenum fluidly coupled to a high-pressure fluid source. An insulated tube disposed at the inlet of the first wall delivers a third fluid. The mixing conduits fluidly couple the high-pressure plenum to the main passage, where the high-pressure fluid is mixed with low-pressure fluid and the third fluid. Optionally, the fluid plenum may house a fourth fluid that is injected through injection holes in the mixing conduits. The fluid mixing apparatus may be used to mix one or more fuels with high- and low-pressure air in a gas turbine combustor. Alternately, the fluid mixing apparatus may mix a fluid with high- and low-pressure water streams.

A transportable system for creating an oxidation reduction potential (ORP) in water employs a pipe assembly for in-line mixing. The pipe assembly includes a first flow path for water to flow through. The first flow path includes one or more ozone intake ports that are fluidically coupled to one or more ozone output ports of an ozone supply unit. The pipe assembly further includes a second flow path fluidically coupled in parallel with the first flow path. The second flow path includes a control valve that selectively permits a portion of the water to flow through the second flow path to produce a negative pressure in the first flow path so that ozone is drawn into the first flow path through the one or more ozone intake ports and mixed into the water flowing through the first flow path.

A liquid aerating device is presented. The device includes a first inner channel through which air flows in a first direction, a second inner channel extending substantially parallel to the first inner channel, wherein liquid flows through the second inner channel in a second direction that is opposite of the first direction, and an aeration chamber. The aeration chamber is connected to the first inner channel and the second inner channel, and positioned such that the air flows into the first inner channel from the aeration chamber and the liquid flows out of the second inner channel into the aeration chamber.
