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.

A fluid mixing and delivery system, e.g., for use in chemical injection of irrigation systems or wash-down stations, has a main fluid conduit with an inlet and an outlet, a bypass conduit with an inlet and an outlet, a venturi, a chemical storage tank, and a static mixer. The bypass conduit inlet connects to the main fluid conduit downstream of the main fluid conduit inlet and the bypass section outlet connects to the main fluid conduit upstream of the main fluid conduit outlet. The venturi is located in-line with the bypass conduit between the bypass conduit inlet and the bypass conduit outlet. The chemical storage tank is fluidly connected to an individual supply line, which fluidly connects to the venturi. The static mixer is located in-line with the main fluid conduit between the bypass conduit outlet and the main fluid conduit outlet.

A method for depressurizing a pipe includes forming, by an ejector assembly, a seal between a first pipe and a second pipe fluidically coupled to the tee pipe fitting. The first pipe flows a first fluid at a first pressure, and the second pipe flows a second fluid at a second pressure lower than the first pressure. The ejector assembly includes a nozzle converging along a flow direction of the first fluid flowing in the first pipe, and a mixing chamber at an outlet of the nozzle, the mixing chamber comprising an outlet is in fluid communication with the second pipe. The method also includes flowing the first fluid from the first pipe into the ejector assembly through the nozzle so that the pressure of the first fluid decreases to a third pressure lower than the second pressure to draw the second fluid into the mixing chamber.

An aspect ratio flow metering device may comprise a concentrate inlet portion, one or more restricted flow portions of tubing fluidly connected to the concentrate inlet portion, and a metered concentrate outlet portion fluidly connected to the one or more restricted flow portion of tubing. The narrowest part of the one or more restricted flow portions of tubing may each have a length (R.sub.L): inner diameter (R.sub.ID) ratio of at least 10:1. The metered concentrate outlet portion may have an inner diameter (O.sub.ID) greater than R.sub.ID. The concentrate inlet portion may have an inner diameter (I.sub.ID) greater than R.sub.ID. The aspect ratio flow metering device may be structurally configured to limit flow of a concentrate into a hydrodynamic mixing apparatus. Also disclosed are methods for using the aspect ratio flow metering device to mix fluids.

Carbonation duct (1) for blending a gas and a beverage. The carbonation duct (1) includes a tubular structure (12) surrounding a compression structure (13), the compression structure (13) longitudinally positioned inside the tubular structure (12) and setting a pathway (14) for the flowing of the beverage along the carbonation duct (1). The compression structure (13) includes external diameters (P,C,G) sequentially defining a convergence path (8), a mixture path (19) and a slowdown path (20) along the carbonation duct (1), wherein, in the convergence path (8), the carbonation duct (1) includes a gas entry portion (9) for gas injection in the pathway (14), and the tubular structure (12) defines a turbilionating projection (10) establishing a carbonation duct (1) mixture diameter (F).

A dielectric assembly for generating ozone includes a positive electrode, a negative electrode, a dielectric for generating the ozone, and a knob adapted to extend outside of a housing into which the dielectric assembly is to be placed. A system is also provided for sanitizing and deodorizing water, food, surfaces and air including a microbiological reduction filter device having an input connected to a water supply, a venturi injector disposed within a housing and connected to an output of the microbiological reduction filter device which generates ozone and mixes the generated ozone with the water, and an electrode assembly comprising a plurality of electrodes, a dielectric for generating the ozone, and a knob extending outside of the housing. The dielectric in a first embodiment and the entire dielectric assembly in a second embodiment can be removed from the housing and replaced in its entirety by the knob.

A water container with an ozone diffuser is an apparatus that is used to diffuse ozone gas into water that is either flowing through the apparatus or is retained by the apparatus. The apparatus includes an aeration chamber, an ozone generator coupler, a distribution hub, a plurality of porous tubes, and a degassing unit. The ozone generator coupler allows the apparatus to connect with a pressurized supply of ozone gas. The aeration chamber is used to retain the water that is currently being aerated by the ozone gas. The distribution hub receives the ozone gas from the ozone generator coupler and distributes the ozone gas amongst the porous tubes. The ozone gas is then evenly inserted from the porous tubes into the water retained by the aeration chamber. The degassing unit is used to neutralize the excess ozone before exhausting the excess ozone into the apparatus's surroundings.

A connector for a fire suppression system includes a body, an inlet, an outlet, an inner volume, a venturi portion, and an air inlet. The inlet includes an inlet aperture configured to receive a fire suppressant agent. The outlet includes an outlet aperture configured to output aspirated fire suppressant agent. The inner volume of the body defines a fluid flow path between the inlet and the outlet. The venturi portion is positioned along the fluid flow path of the inner volume and is configured to produce a low pressure region within the inner volume of the body. The air inlet is configured to provide air to the low pressure region.

A tap apparatus including a container coupling portion including a liquid inlet portion, a body portion, and a plug valve portion. The body portion includes a liquid outlet portion, wherein the liquid outlet portion is in fluid communication with the liquid inlet portion of the container coupling portion. The plug valve portion is configured and arranged to be seated within the body portion, wherein the plug valve portion is configured and arranged to be moved relative to the body portion between an open position, in which a liquid is free to flow from the liquid inlet portion and out through the liquid outlet portion, and a closed position, in which liquid from the liquid inlet portion is prevented from flowing out through the liquid outlet portion. The body portion also includes a plurality of flow channels provided in an interior surface thereof.

A gas dissolving system using double mixers to generate a higher gas concentration in liquid is disclosed. The gas dissolving system includes two gas mixers, a degassing device, pressure valves, a pressure sensor, and a pump. Liquid flows through mixers to entrain gas therein, and it thus contains dissolved gas and undissolved gas. The liquid subsequently flows into the degassing device so that undissolved gas is released to the outside environment, and dissolved gas remains in the liquid. The liquid with dissolved gas combines with raw liquid and is diluted so that it becomes liquid with a desired gas concentration as the output. A high gas concentration of liquid is obtained after more cycles of fluid flow through the mixers to dissolve gas without combining raw liquid.
