A system for mixing and mixing processes and structures are disclosed. In addition a nozzle used for mixing is disclosed.

A submersible aerator apparatus is disclosed. The apparatus uses injected air to create both aeration and mixing of a liquid. The apparatus is submersible and may be lowered into a container holding a liquid with suspended and coagulated solids, such as fats, oil, and grease (FOG). Air supplied to the apparatus is injected into the liquid through a hose, which results in an upward flow of large air bubbles and entrained liquid. The upwardly moving large air bubbles are cleaved (i.e., broken apart) by a series of baffle plates that are generally perpendicular to the direction of flow of the air bubbles. This action mixes and aerates the liquid.

A discharge system includes a mixing vessel and a feedstock input in fluid communication with the mixing vessel. A solvent input is in fluid communication with the mixing vessel. A discharge output is in fluid communication with an outlet of the mixing vessel to discharge effluent. A method for generating turbulence on a liquid surface within a discharge system includes supplying a mixing vessel with feedstock fluid and solvent fluid to generate a liquid mixture and a gas pocket in the mixing vessel. The method includes supplying an impinging solvent fluid through a nozzle extending from a first end of the mixing vessel to generate a roiling surface at an interface between the gas pocket and the liquid mixture and permit uptake of gas from the gas pocket into the liquid mixture.

Ultrafine bubbles with a diameter of less than 1.0 m are generated in liquid by causing film boiling in liquid by means of a heater.

A device for bubbling a gas into a liquid is disclosed. The device comprises a first bubbling apparatus nested inside a second bubbling apparatus. The first bubbling apparatus comprises a gas inlet for receiving the gas and a plurality of first openings for releasing the gas. The second bubbling apparatus at least partially encloses the plurality of first openings of the first bubbling apparatus. The second bubbling apparatus receives the gas from the plurality of first openings. The second bubbling apparatus comprises a plurality of second openings for bubbling the gas into the liquid.

A water aeration system powers an air pump held in an encasement with a solar panel mounted directly or indirectly to the encasement or to the mounting pole supporting the encasement above a ground surface. An air conduit directs pumped air to one or more disc diffusers submerged in the body of water to be aerated. The disc diffuser(s) are supported by a floating platform that is suspended from a buoy or float so that the disc diffuser(s) are held at a desired depth below the water surface.

The present disclosure provides a system for producing carbon dioxide (CO.sub.2)-dissolved deionized water (DIW), the system comprising: a DIW source for providing DIW; a CO.sub.2 source for providing CO.sub.2; a pressurized tank, coupled to the DIW source and the CO.sub.2 source, the pressurized tank being arranged for generating CO.sub.2-dissolved DIW with a first concentration according to the DIW of the DIW source and the CO.sub.2 of the CO.sub.2 source; a mixer, coupled to the DIW source and the pressurized tank, the mixer being arranged for generating CO.sub.2-dissolved DIW with a second concentration according to the CO.sub.2-dissolved DIW with the first concentration and the DIW of the DIW source; and wherein the second concentration is lower than the first concentration.

A method for assembling a mixer-container intended for receiving a biopharmaceutical fluid includes providing a container with a mixing device including at least one shaft having an adjustable length, and at least one first bearing attached to a wall of the container, the shaft extending at least into the inner space from the first bearing; a rigid outer device that compresses the container; and a drive motor located outside the container, the first bearing of the container is placed so as to be spaced apart from the motor, and the length of the shaft is adjusted along the main axis by arranging the shaft opposite the motor to enable the motor to rotate the shaft.

A heating medium injector includes an injector structure defining a heating medium flow path and a product flow path. The heating medium flow path extends to a contact location along an axis of the injector, while the product flow path also extends to the contact location along the injector axis. The contact location comprises a location at which the heating medium flow path and product flow path merge within the injector. In a region along the injector axis, the product flow path is defined between a first flow surface and a second flow surface. The first flow surface comprises a surface of a boundary wall separating the heating medium flow path from the product flow path and the second flow surface comprises a surface of an opposing second boundary wall. The second flow surface is in substantial thermal communication with a second flow surface cooling structure.

An ozone water treatment system using low energy. The present invention includes: a water pipe through which raw water, to be treated, is transferred and supplied while having energy; a gas injector for dispersing and injecting, in a micro bubble form, ozone gas to the raw water supplied and transferred from the water pipe; a low-energy using-type gas-liquid contact reactor for promoting a contact reaction between the ozone gas and the raw water within ozone mixed water supplied and transferred from the gas injector; and a discharge pipe for continuously transferring and discharging treated water having been reaction-treated. Therefore, since energy use during the ozone gas injection and the contact reaction can be remarkably reduced, processing costs can be reduced.
