A mixing apparatus includes an inner container and an outer container which define mixing fluid passageways between them. The inner container is received in the outer container with at least two different orientations. Each orientation forms a different set of passageways each including a mixing chamber and a riser passage, where the passageways lead from the inner container to the mixing chamber. The different orientations create different designs of the passageways, to give different mixing functionality.

Aspects of the present disclosure provide various apparatus and methods. In some embodiments, an apparatus is provided for mixing a gas with a liquid. The apparatus may include a pipe having two ends. The pipe may provide a main fluid path and may have an interior surface having a first groove. The apparatus may also include a helical vane disposed inside the pipe. The vane may have a first projecting tongue that engages the first groove. The apparatus may also include a gas injection port on the pipe adapted to inject gas into the fluid path upstream of the helical vane. In some embodiments, the helical vane may be a 3D printed component.

A bubble generator includes an ejector including a flow passage, a water supplier that supplies water into the flow passage, an air supplier that supplies air into the flow passage, a cleaner supplier that supplies a cleaner into the flow passage, and a bubble discharger that discharges bubbles generated by mixing the water, the air, and the cleaner; a water supply device that supplies water to the flow passage via the water supplier, and a cleaner supply device that supplies the cleaner to the flow passage via the cleaner supplier. The cleaner supplier is formed on a lower surface of the flow passage.

An apparatus for increasing gas components in a fluid uses a controller connected to a network and client device for remote control of fluid flow rates, magnet field intensity, and pressure of fluid based on preset parameters. Conductive wire coiled around a magnet fluid treatment device generates a bidirectional magnetic flux to magnetically treat fluid in the conduit at an entry pressure. A variable frequency generator energizes the wire creating magnetic flux lines to pass through the fluid flow conduit. A gas injector receives fluid at the gas injector entry pressure and lowers the gas injector entry pressure of the fluid to a gas injector discharge pressure. A treatment chamber receives the fluid at a treatment chamber entry pressure and lowers the treatment chamber entry pressure to a treatment chamber discharge pressure. The apparatus causes absorption of increased gas component into the fluid by from 10% to at least 500%.

A valve for dispensing a liquid includes a housing, an internal liquid passage extending through the housing, a valve seat, a valve member movable between a closed position engaging the valve seat and an open position disengaging the valve seat, and a control member controlling movement of the valve member, which is movable between a first position in which it engages the valve member in its closed position, a second position in which the valve member is in its open position but still engaging the control member and a third position in which the valve member is in its open position and out of engagement with the control member. At least one air passage connects the outside of the valve with the internal liquid passage. The at least one air passage is closed in the first and second positions of the control member and is opened in the third position.

Systems and methods for dissolving ozone gas in a liquid. An embodiment can comprise a tank having an upper region, a lower region, and a discharge outlet, all disposed in a specified geometry. A pump can be coupled with a liquid inlet in order to receive a liquid therefrom and to deliver the liquid via a pipe to the upper region of the tank. The pump can be coupled with the lower region of the tank in order to receive the liquid from the tank and to recirculate the liquid to the upper region of the tank. The apparatus can include an ozone inlet to receive ozone into the tank. The ozone inlet can comprise a venturi inlet disposed on the pipe downstream of the pump. The liquid can be released from the tank and depressurized, thereby providing for the ozone to emerge from the liquid as gas bubbles. The released liquid can be selected for a two-stage gas and aqueous cleaning process.

A gas infusion waste water treatment facility having an apparatus for increasing gas components in a fluid uses a controller connected to a network and client device for remote control of fluid flow rates, magnet field intensity, and pressure of fluid based on preset parameters. Conductive wire coiled around a magnet fluid treatment device generates a bidirectional magnetic flux to magnetically treat fluid in the conduit at an entry pressure. The facility creates absorption of increased gas concentration containing an oxygen atom into the fluid from 10% to at least 500%.
