An apparatus for manufacturing water having a high concentration of dissolved ozone is characterized by being configured by connecting: a filtering device; a water tank connected to the filtering device; a pump connected to the water tank; a Venturi tube connected to the pump; a first gas dissolving pressure device connected to the Venturi tube; and a second gas dissolving pressure device connected to the first gas dissolving pressure device.

Carbonation apparatus is provided for carbonating a mixed input flow of pressurized and refrigerated carbon dioxide and water. A first cartridge is disposed within the carbonation chamber, defining a porous micromesh net in fluid communication with the input flow and a central cavity in fluid communication with the carbonation chamber output port. The micromesh net is configured to break up chains of water molecules passing through the net, to enhance bonding between the water and carbon dioxide molecules within the cartridge. The net also responds to the flow of water and carbon dioxide molecules impacting and passing through the net by generating a passive polarizing field that has a polarizing influence on the water molecules to further enhance. Beads may be provided within the cartridge for capturing and stabilizing carbon dioxide molecules to yet further enhance bonding between the water and the carbon dioxide molecules.

There is provided an inline saturator system and method for gas exchange with an aqueous-phase liquid. The system includes a pressure vessel, configured to receive a first liquid and a first gas from external sources and to discharge a second liquid and a second gas from the pressure vessel, and a gas infusion device situated within the pressure vessel. The gas infusion device is configured to receive the first liquid and first gas, to facilitate gas exchange therebetween, producing the second liquid and the second gas, and to discharge the second liquid and second gas into the pressure vessel. The system further includes a recirculation system configured to direct a portion of liquid within the pressure vessel back into the saturator device, where injection of the redirected liquid into the gas infusion device forces the first liquid into the gas infusion device for the gas exchange.

An aeration device pertaining to the technical field of sewage treatment includes a flow mixing chamber and an air inlet chamber. The flow mixing chamber has a liquid inlet opening, a liquid outlet opening, and an air inlet hole penetrating the chamber wall and located inside the air inlet chamber. The air inlet chamber has an air inlet opening and an interior space whose cross-sectional area is gradually reduced along the liquid flow direction in the flow mixing chamber. The cross-sectional area and number of the air inlet hole can be properly set in order for the mixed fluid produced by the aeration device to have relatively high-density small-diameter air bubbles that contribute to mixing the liquid flow and air flow sufficiently, dissolving oxygen rapidly and sufficiently into the liquid flow, increasing the oxygen dissolution rate of the mixed fluid, and enhancing aeration efficiency.

Various implementations include an aeration device. The aeration device includes a venturi tube and an outlet tube. The venturi tube has an outlet port and an air intake port. The outlet tube has a first end coupled to the outlet port of the venturi tube, a second end opposite and spaced apart from the first end, and an intermediate portion disposed between the first and second ends of the outlet tube. The intermediate portion is helically shaped and extends around a helical axis of the intermediate portion. The intermediate portion extends at least one rotation about the helical axis.

The apparatus includes: a producing unit that generates ultrafine bubbles in a liquid supplied from a liquid introducing unit to produce an ultrafine bubble-containing liquid containing the ultrafine bubbles, and delivers the ultrafine bubble-containing liquid; a liquid delivering unit that delivers the ultrafine bubble-containing liquid to an outside; a buffer tank that receives the liquid delivered from the producing unit and delivers the liquid to the liquid delivering unit; and a controller that controls the delivery of the ultrafine bubble-containing liquid from the buffer tank to the liquid delivering unit such that, if the producing unit stops operating, an ultrafine bubble-containing liquid accumulated in the buffer tank is delivered to the liquid delivering unit to enable the liquid delivering unit to deliver the ultrafine bubble-containing liquid to the outside.

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 system for producing a liquid with gas bubbles. The system has an eductor to mix a liquid stream and a gas stream to a form of a liquid-gas mixture and a mixing column with a stack of filling layers to reduce a size of gas bubbles within the liquid-gas mixture. The stack of filling layers has a plurality of porous layers separated alternately by plate layers and ring layers.

An ozone water generating device includes a housing, an ozone generator for generating ozone, and an ejector having a water inlet, a water outlet, and an air inlet. The ozone generator and the ejector are installed in the housing. An exit of the ozone generator is connected to the air inlet of the ejector. The ozone water generating device can directly output ozone water, and has a compact structure and is small in size.

A system and method for creating an oxidation reduction potential (ORP) in water and for reducing the surface tension of the water for the pathogenic cleansing and/or degreasing of hard surfaces and equipment. The hard surfaces to be cleansed and/or degreased may be plastic, glass, ceramic, porcelain and stainless steel. The equipment to be cleansed and/or degreased may be food service equipment such as ovens, ranges, fryers, grills, steam cookers, refrigerators, coolers, holding cabinets, cold food tables, work tables, beverage dispensing equipment, beer dispensers, shelving, food displays, dish washing equipment and grease traps.
