A fluid injection system is a system that enables the automatic mixing and dispensing of select additives to desired output locations. The system may include at least one supply line, at least one pumping mechanism, at least one injection assembly, and a base controller. The at least one supply line carries the supply flow from a supply source for the mixing and the distribution of the selected additives to the desired output locations. The at least one pumping mechanism facilitates the injection of the additives to the supply flow being carried by the at least one supply line. The at least one injection assembly enables the introduction of the combined additives into the supply flow via the at least one pumping mechanism. Finally, the base controller monitors the injection of the right amounts of additives as well as the correct combination of the additives being injected into the supply flow.

An after treatment system (ATS) for a vehicle includes, fluidly connected in series, an inlet, a urea mixer and an outlet. The inlet is fluidly connected to an output of an engine of the vehicle and the outlet is fluidly connected to an outlet tube of the vehicle. The urea mixer is provided with a dosing module, an inner element and an outer element. The inner element is configured such that a first flow of exhaust gas flow flowing from the inlet into the urea mixer flows into an first volume defined by the inner element. The outer element is configured such that a second flow flows in a volume defined between inner element and outer element, wherein the first and second flows rejoin together in a mixing chamber fluidly connected to the volume and to the first volume downstream with respect inner and outer elements.

Provided is a ultrafine bubble generating apparatus capable, when generating nanobubbles in a liquid, of appropriately mixing a gas into a liquid ejected from a liquid ejector. The ultrafine bubble generating apparatus comprises a liquid ejector for ejecting a liquid, a gas mixer for pressurizing and mixing a gas into the liquid ejected from the liquid ejector, and an ultrafine bubble generator for generating nanobubbles in the liquid by passing the liquid with intermixed gas therethrough. Between the liquid ejector and the ultrafine bubble generator, the gas mixer pressurizes and mixes the gas into the liquid, which is flowing in a pressurized state toward the ultrafine bubble generator.

A system and method for creating an oxidation reduction potential (ORP) in water and for reducing the surface tension of the water for the microbiological decontamination of food animal carcasses. A method is also described for the microbiological decontamination of beef trimmings.

A mixing device for mixing exhaust gas from a combustion engine of a vehicle with a solution for lowering the content of nitrogen oxides in the exhaust gas includes a casing with an exhaust inlet, an exhaust outlet, and a corner region in which an exhaust gas flow is diverted toward the exhaust outlet. The corner region has an opening for a dosing unit. A flow guide is arranged within the casing. The flow guide is configured to divide a total of the exhaust gas flow into a first exhaust gas stream and a second exhaust gas stream. A gap for the second exhaust gas stream is formed between the flow guide and a side wall of the casing. In the side wall the opening for the dosing unit is located. An end region of the flow guide is arranged upstream of the opening for the dosing unit.

Provided is a liquid supply apparatus which is capable of directly taking in a liquid from a flow channel and appropriately mixing a gas into the liquid when generating-nanobubbles in the liquid using an ultrafine bubble generating apparatus. The liquid supply apparatus comprises a flow channel for a liquid supplied from a liquid supply source and an ultrafine bubble generating apparatus for generating nanobubbles in the liquid. The ultrafine bubble generating apparatus is provided with: a liquid ejector for ejecting the liquid taken in from the flow channel; a gas mixer for pressurizing and mixing a gas into the liquid ejected from the liquid ejector; and a nanobubble-generating nozzle for generating nanobubbles in the liquid by passing the liquid with intermixed gas therethrough. The pressure of the liquid in the flow channel flowing into the liquid ejector from the upstream-side of the liquid ejector is a positive pressure and, between the liquid ejector and the-nanobubble-generating nozzle, the gas mixer pressurizes and mixes the gas into the liquid, which is flowing in a pressurized state toward the nanobubble-generating nozzle.

A system for introducing bulk dry material into a fluid system includes a vessel, wherein the vessel is closed; an outlet wherein the outlet is located on a bottom of the vessel; a valve controlling the outlet; corner locking pins located on the outside of the vessel; a scale; and a controller. The system may include a conveyor; a hopper; a motor; and a shearing device.

A method and an installation for treating a main wastewater stream flowing in a closed conduit with a flow direction. The method includes the steps of: introducing a liquid into at least one pre-treatment stream; generating a gas stream containing ozone gas; introducing the gas stream into the at least one pre-treatment stream, each with a gas injector, resulting in at least one mixed-phase stream comprising ozone laden gas and liquid; passing the at least one mixed-phase stream through at least one static mixer, resulting in a predefined gas bubble size; and injecting the at least one mixed-phase stream in the main wastewater stream perpendicular to the flow direction.

A pressure washer includes a pump for pressurizing a primary fluid flow, the pump including a pump inlet for receiving fluid from a common fluid source and a pump outlet for supplying a pressurized primary fluid and a jet pump including a primary fluid inlet fluidly coupled to the pump outlet, a secondary fluid inlet configured to receive fluid from the common fluid source, and a fluid outlet. In a high pressure operating mode, all of the pressurized primary fluid flows through the jet pump and exits through the fluid outlet of the jet pump. In a high flow operating mode, all the pressurized primary fluid flows through the jet pump and entrains a secondary fluid supplied through the secondary fluid inlet from the common fluid source so that the secondary fluid also flows through the jet pump, resulting in a combined fluid flow of the primary fluid and the secondary fluid that exits through the fluid outlet of the jet pump.

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.
