A ballast water treatment apparatus and a ballast water treatment system having a ballast water treatment apparatus are provided. The ballast water treatment apparatus includes a ballast water transport line configured to transport ballast water between a first location and a second location, the transported ballast water being passed through at least one injector, and a plasma generation device configured to be fed with a feed gas optionally comprising oxygen, and configured to generate a feed gas plasma by a streamer type discharge in a discharge area to provide a treated gas at a treated-gas outlet. 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.

The mixing nozzle has a throat section, a diffuser section, a gas nozzle section, a first liquid suction port, a liquid nozzle section, a second liquid suction port, a baffle plate, and a jetting port. The first liquid suction port liquidly absorbs the solution in the water storage pool from a side of the gas nozzle section toward the gas nozzle tip. The liquid nozzle section extends to the downstream side of the gas nozzle section with intervening the first liquid suction port. The second liquid suction port liquidly absorbs the solution in the water storage pool from a side of the liquid nozzle section toward the liquid nozzle tip. The baffle plate is provided such that the mixed flow mixed in the diffuser section collides in front of a downstream end of the diffuser section, and divides and reverses the mixed flow.

A production apparatus for a liquid containing gas bubbles includes a casing, a pump unit, and a gas bubble-mixing unit. The casing is provided with a main flow channel for a liquid, the main flow channel having a liquid inflow port and a liquid outflow port. The pump unit is disposed in the main flow channel and pumps the liquid to the liquid outflow port from the liquid inflow port. The gas bubble-mixing unit includes a first choke portion that is disposed in the main flow channel and has an inner diameter decreased and a gas supply channel that supplies the first choke portion with a gas.

The invention relates to a method and a device for improving the biodegradability of an organic sludge. It comprises at least two treatment cycles each of a total duration of between around 8 s and around 20 s and each comprising a first step of producing a first hydrolysed sludge emulsion in a first, reduced zone, by injecting a gas into said reduced zone. a second step of abruptly expanding the emulsion in a second zone—the expansion zone—and a third step of recovering the emulsion via a third, restriction zone.

This invention is a mobile water and chemical delivery system that allows for the injection of a chemical in the path of the water line under high pressure. The system allows for mobile agricultural workers to move large quantities of clean water between job sites to use to deliver agricultural chemicals inline without having to carry large quantities of chemicals into the field. The chemicals are injected between the mobile water tank and the hoses that take the water from the tank to the application site. The purity of the mobile water source remains constant even if there is a change in the chemical.

A ballast water treatment apparatus and a ballast water treatment system having a ballast water treatment apparatus are provided.

The treated-gas outlet is in gaseous connection with the injector gas inlet.

The present device is a gas-liquid mixing device having a venturi structure A in which a throttle portion and a conical portion are provided in a main passage through which a liquid passes, including: a gas mixing passage for taking in gas from a tangential direction with respect to the main passage having a circular cross section; and a protruding portion provided on a downstream side of the gas mixing passage of an inner wall forming the main passage and extending in a central axis direction of the main passage. It is preferable that the protruding portion is provided on an inner wall forming the conical portion, and is formed such that a protruding height from the inner wall increases toward the downstream side.

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 beverage container may comprise a beverage container lid assembly comprising at least one concentrate well to hold a concentrate vessel, a concentrate vessel retainer for each concentrate well to secure the concentrate vessel in the concentrate well, a feed line for each concentrate well comprising a feed line needle to puncture the concentrate vessel in the at least one concentrate well, a Venturi mixer in fluid communication with each feed line, a mixing valve in fluid communication with each feed line, wherein fluid flows from the concentrate vessel to the Venturi mixer when the mixing valve is open and the concentrate vessel is punctured by the feed line needle. Methods of using the beverage container and beverage container lid assembly are also described.

A flue ozone distributor applied in a low-temperature oxidation denitrification technology and an arrangement manner thereof is disclosed. The flue ozone distributor comprises a distribution main pipe, multiple distribution branch pipes, Venturi distributors and delta wings. The distribution branch pipes are led out from the distribution main pipe as parallel branches. The Venturi distributors are arranged with an equal space on the distribution branch pipes. The delta wings are arranged on one diffusion segment side of the Venturi distributors. The flue ozone distributor is arranged in the flue. The technology is used in the field of denitrification for flue gas of an industrial boiler/kiln by a low-temperature ozone oxidation method. The ozone-injecting direction is consistent with a flow direction of the flue gas. A soot deposit congestion problem does not exist. A turbulent flow behavior of the flue gas and ozone is strengthened. The oxidation efficiency is improved.
