A beverage aerator includes a housing, a pump-motor assembly, an uptake tube, and a spray nozzle. The housing is sized to removably seat on a neck of a decanting vessel. The pump-motor assembly is positioned within the housing, and has a pump inlet and a pump outlet. The uptake tube is fluidly coupled to the pump inlet upstream of the pump inlet. The uptake tube has a tube inlet end located below the housing. The spray nozzle is fluidly coupled to the pump outlet downstream of the pump outlet. The spray nozzle is located below the pump-motor assembly and oriented to have a laterally-outward discharge direction.

A mobile submersible mixer comprising a mobile platform, frame or chassis with a plurality of wheels, with one or more mixing jets or systems mounted thereon. The apparatus also may comprise an aeration system and real-time sampling system. The apparatus is introduced into a pit or tank, typically by rolling the mixer down a ramp into the pit or tank.

A mixing element in which spiral blade edge portions are disposed in a tube wall portion of a passage tube through which fluid flows and an opening section of the passage tube and the blade edge portions are joined to each other is provided. In an existing manufacturing method using a gas welding machine, when, for example, a mixing element having an inside diameter of 130 mm is to be manufactured, eight 90-degree rotation type spiral blades can be disposed at most. In a method for manufacturing the mixing element according to the present invention, it is possible to manufacture a mixing element including 10 or more blades by using a laser processor.

An aerator for adding oxygen to a body of water. A pair of tubes is mounted to a plate, in turn, connected to a pair of floats suspending the aerator in the body of water. A source of pressurized air directs air flow through the tubes forcing water flow into the tubes and out vertical risers whereat the oxygenated water then falls back onto the body of water.

An aeration system may have a submersible aerator that may be located on the bottom of a body of water and a floating aerator that may operate directly above the submersible aerator. The submersible aerator may create a laminar column of bubbles and may be powered by an air compressor. The floating aerator may use a motor driven propeller to agitate water on the water surface. A controller may determine when to operate the aerators, and may operate them separately or together in some instances. Some embodiments may have a controller that operates the aerators differently based on energy supply, which may vary in solar powered systems with a battery bank.

The present invention relates to a reaction device with air-lift type internal circulation which includes:a vertical cylindrical volume;a vertical element positioned within said volume in such a way as to form an interspace with the walls of said volume, having a cross-section which is circular and orthogonal to the vertical axis of the element and with a variable internal diameter along said axis, said element being denoted draft tube;at least one gas distributor positioned on the bottom of said device; said device being characterised in that:the ratio between the diameter of the internal vertical element and the internal diameter of the cylindrical volume ranges from 0.05 to 0.5, andthe ratio between the height of the vertical element and the height of the cylindrical volume is less than 0.5.

Equipment for massive dissolution of gases in liquids via the formation of thin liquid films and the exchange of gases with said films. The equipment provides movement of liquids over great distances via the upward movement of bubbles therein. The equipment can alter the direction of the flow of water, said aspect being useful for the recovery of liquid bodies. In addition to providing a high rate of dissolution of gases in liquids, the equipment is very energy-efficient and has a very large volumetric capacity, thereby being useful for the preservation and/or recovery of liquid bodies, being able, in certain applications, to operate in an energy-autonomous manner. The equipment can be used in situations where energy-efficient dissolution of gases in liquids is desired, such as the preservation and/or recovery of liquid bodies; processes for preserving and/or improving the productivity of aquaculture systems; wastewater treatment systems; and the fixation of gases.

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. Air supplied to the apparatus is injected into the liquid which results in an upward flow of air bubbles and entrained liquid. This action mixes and aerates the liquid. A method of using a submersible air-injection aerator is also disclosed.

The system and method for energy generation along with fluid treatment includes but not limited to aeration, filteration and heat transfer or temperature control. The system may comprise at least one first enclosed chamber. Further plurality of nozzles are configured to allow flow of the fluid into the at least one first enclosed chamber. The system further comprises plurality of second chambers connected to the at least one first enclosed chamber through a network of pipes. Further the system comprises an aerofoil turbine mounted in the plurality of second chambers, wherein the aerofoil turbine is configured to receive a second fluid (example: atmospheric air) via plurality of inlets ports positioned on periphery of the aerofoil turbine.
