A system for creating an oxidation reduction potential (ORP) in water employs a plurality of ozone supply units housed in separate enclosures. The ozone supply units feed into a manifold that 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 each ozone supply unit. The manifold includes a plurality of flow switches configured to transmit control signals to one or more controllers of each ozone supply unit in response to sensing a flow of water through the fluid paths in order to cause the ozone supply units to generate ozone. The manifold also includes a plurality of fluid mixers that are fluidically coupled to the ozone intake ports and configured to introduce the ozone generated by the ozone supply units into the water flowing through the fluid paths.

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 cavitator of a microbubble generator, the microbubble generator and a washing device. The cavitator has a cavitation inlet and a cavitation outlet, at least one Venturi channel extending from the cavitation inlet towards the cavitation outlet is defined in the cavitator, and in the water flow direction, each of the Venturi channels includes a tapered section, a venturi and a divergent section in sequence, an open area of the tapered section is decreased gradually in a direction from the cavitation inlet to the throat pipe, an open area of the divergent section is increased gradually in a direction from the throat pipe to the cavitation outlet, and the throat pipe has a diameter of 0.2 mm to 2.0 mm.

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.

A chemical dispenser for a chemical dispensing system is disclosed. The chemical dispenser includes an input selector valve having an opened position and a closed position and configured to be coupled to a diluent source, a diverter valve coupled to the input selector valve, and a plurality of eductors coupled to the diverter valve. The diverter valve includes a valve head having a diluent port, a valve seat having a plurality of eductor ports, wherein each eductor port is in communication with a respective one of the plurality of eductors, and a drive mechanism coupled to the valve head and configured to move the valve head relative to the valve seat. The valve head may include one or more pressure relief ports for equalizing the diluent pressure across the valve head. A chemical dispensing system including the chemical dispenser and a method of using the chemical dispenser are also disclosed.

A dispenser for dispensing a beverage from a beverage bottle, especially for dispensing wine from a wine bottle and facilitating the aeration of the dispensed wine while it is being poured to shorten the time normally devoted to breathing the wine. An open lesser end of the dispenser inserts into the neck of a wine bottle and preferably seals therein. A valve may be closed to temporarily preserve the wine in the bottle for later aeration while dispensing.

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.

A water treatment system includes a water passage, a magnet and a hydroxyl radical generator. Water flows through the water passage. The magnet is adjacent to the water passage and produces a magnetic field in the water passage, The hydroxyl radical generator generates hydroxyl radicals in the water in the water passage. A water treatment method includes the steps of providing a water passage, producing a magnetic field in the water passage, flowing water through the magnetic field and generating, while the water is in the magnetic field, hydroxyl radicals in the water. The water can be recirculated through the water passage a number of times.

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.
