The injector includes a liquid passage having an area constructed such as to increase a velocity of the passed-through water in a region of increased velocity, and an injector gas inlet provided in the region of increased velocity. The treated-gas outlet is in gaseous connection with the injector gas inlet.

A micro-bubble generator is provided between an input end and an output end of a water outlet device. The micro-bubble generator includes a water inlet member and a water outlet member. A gas inlet gap is remained between the water inlet member and the water outlet member, with the gas inlet gap being communicated to external air, such that the external air is allowed to enter the micro-bubble generator for gas-liquid mixing and generate minute and dense bubbles.

A micro-bubble spray head and a washing apparatus. The micro-bubble spray head includes an integrated spray tube and a micro-bubble bubbler fixed on the outlet end of the integrated spray tube; a throttling passage portion is formed in the integrated spray tube; a plurality of throttling passages parallel to each other and having a uniform cross section are formed in the throttling passage portion along a water stream direction, so that a plurality of water streams can be formed in the plurality of throttling passages parallel to each other and having the uniform cross section and are sprayed out from the outlets of the plurality of throttling passages parallel to each other and having the uniform cross section in an expansion manner, so as to form negative pressure near the outlets; a plurality of air inlets serving as air inlet passages are further provided on the integrated spray tube.

The instant invention includes a multiple-Venturi nozzle. The instant multiple-Venturi nozzle has a generally cylindrical body with a generally flat bottom surface and a generally flat distal outer surface and a generally arcuate vertical surface parallel to the bottom and outer surfaces. The instant multiple-Venturi nozzle further includes a plurality of chokes generally perpendicular to the bottom and outer surfaces, each of said chokes extending through the body and having a choke inlet and a choke outlet. The instant multiple-Venturi nozzle further includes a manifold extending from the outer surface partially into the body and a plurality of manifold channels connecting the manifold to each choke, each of said manifold channels being generally perpendicular to a corresponding choke, having a manifold outlet and a distal manifold inlet and being offset in a helical distribution from other manifold outlets corresponding to the same choke.

An apparatus for continuously generating and controlling the density of foam has a fluid in-flow manifold in communication with a source of liquid and comprising a pressure sensor. A plurality of branch lines are in fluid communication with the in-flow manifold a foam out-flow manifold. Each branch line has a flow control valve, a Venturi tube and in fluid communication with a throat of each Venturi tube an air induction control valve. The foam out-flow manifold has a pressure sensor. At least one in-flow control valve is disposed between the source and the in-flow manifold and at least one out-flow control valve is in communication with the out-flow manifold. The branch valves, air valves, the in-flow control valve and the out-flow control valve are operable to provide a chosen flow rate of the liquid and a selected foam product flow rate at a selected density of the foam product.

A transportable system for creating an ORP in water includes an ozone supply unit and a manifold housed in separate enclosures on a wheeled frame. The ozone supply unit feeds into the manifold which contains a plurality of fluid paths and has one or more ozone intake ports. The ozone intake ports are fluidically coupled to one or more ozone output ports of the ozone supply unit. The manifold includes flow switches configured to transmit control signals to one or more controllers of the ozone supply unit in response to sensing a flow of water through the fluid paths in order to cause the ozone supply unit to generate ozone. The manifold also includes fluid mixers that are fluidically coupled to the ozone intake ports and configured to introduce the ozone generated by the ozone supply unit into the water flowing through the fluid paths.

A fragrance dispensing system includes a first and a second container each having a main tube for the expulsion of a fragrance contained therein, and a dispensing device that provides a dispensing path towards an outlet section and that includes a mixing chamber and a first and second auxiliary tubes connected at one end to the mixing chamber. A containing case forms a seat containing the first and second containers, and a cap is configured to be applied on the containing case and houses the mixing chamber, an outlet section for the mixed fragrances and, at least partly, and the first and second auxiliary tubes, each of which has a free end separably connected to one of the main tubes when the cap is engaged to the case.

A system for meat processing may include: a conveyor configured to transport animal carcasses or portions of meat through a meat processing facility; and a spray system configured to spray each of the animal carcasses or portions of meat with aqueous ozone when each of the animal carcasses or portions of meat is transported to the spray system by the conveyor. The system may further include a second spray system configured to spray each of the animal carcasses or portions of meat with lactic acid or citric acid when each of the animal carcasses or portions of meat is transported to the second spray system by the conveyor.

A first solution is mixed and diluted with diluting liquid to make a first dilute solution, a second solution is mixed and diluted with diluting liquid to make a second dilute solution, and the first dilute solution and second dilute solution, both diluted with diluting liquid, are mixed in a sealed tank.

An aerator has a submersible mixing tube having a water inlet and an aerated water outlet. An aspirating tube penetrates the mixing tube between the water inlet and the aerated water outlet, the aspirating tube having an air outlet introducing air into the mixing tube and an air inlet drawing in air from atmosphere above a water surface. The mixing tube has an outboard motor lower unit engagement to engage a lower unit of an outboard motor in use such that a propeller thereof locates entirely within the mixing tube with a midsection of the outboard motor extending from the engagement. As such, the propeller of the outboard motor lower unit thrusts water past the air inlet thereby creating suction at the inlet to draw air via the mixing tube to mix with the water to expel a plume of aerated water.
