A system for a live well fill pump fulfills the dual goals of keeping the intermittently operating fill pump primed and dissolving gasses in water sourced by the fill pump. A check valve in a water intake assembly cooperates with a check valve in a pump output assembly to keep the fill pump primed in between intermittent pumping operations. Water flowing out of the fill pump through the second check valve undergoes a pressure differential and turbulence. A gas delivery system directs the turbulent water through the output conduit or chamber to dissolve the gas in the water. The gas-saturated water is released through the water outlet into the container.

The invention relates to a diffusor for adding of gases into water, said diffusor comprising a perforated tube (1) and at least one supply tube (2), said the at least one supply tube (2) is at one end coupled to a source for supplying gas and at the other end in fluid communication with the perforated tube (1), the gas is supplied to the perforated tube (1) through at least one inner supply tube (4; 5; 15) extending from the supply tube (2) to the perforated tube (1). The invention is distinctive in that at the least one inner supply tube (4; 5; 15) is a non-perforating tube and has at least one outlet (4a, 5a, 15a) situated at a free end of the at least one inner supply tube (4, 5, 15), said gas is adapted to be distributed into the perforated tube (1) through the at least one outlet (4a, 5a, 15a).

A stabilized, gas-infused liquids containing ultra high concentrations of infused gas, produced by: generating a gas-infused liquid in a sealed vessel under a high pressure of at least 20 psi; stabilizing the gas-infused liquid by passing the liquid while still under the high pressure through a tubular flow path arrangement which compresses the infused gas into nano bubbles in the liquid; infusing an additional amount of the gas into the stabilized liquid by injecting the same, while still under high pressure, back into the sealed pressure vessel along with more of the gas; and again stabilizing the liquid by again passing liquid, while still under the high pressure, through the tubular flow path arrangement to thereby form the additional amount of infused gas into nano bubbles in the liquid.

The efficiency of water disinfection can be significantly increased by supplying the ozone in combination with oxygen to an inlet of a cavitation pump. The ozone and the oxygen are turned into ultra-fine bubbles via cavitation action within the pump, facilitating the dissolution of the oxygen and ozone within the water. The water mixed with the oxygen and the ozone is subsequently supplied to a line atomizer, where the dissolution of the ozone within the mixture is completed. The combined use of the cavitation pump and the line atomizer can lead to a substantially complete dissolution of the supplied ozone within water that needs to be disinfected, allowing to easily achieve the concentration of ozone necessary for water disinfection. Due to this efficiency, the system and method described are highly scalable and suitable for water purification at water purification plants of various sizes.

Oxygenated beverages are described herein and methods for production of same. In an embodiment, a beverage delivery system is described including a container and an oxygen-containing aqueous liquid wherein the dissolved oxygen content is from about 25 ppm to about 50 ppm, where the liquid and a gas comprising oxygen within the container provide a pressure force of about 20 PSI to about 35 PSI on the interior surfaces of the container, and wherein the nitrogen content is very low causing a force of less than 17 PSI on the interior surfaces of the container.

A system for performing a gas-liquid mass transfer includes a container bounding a compartment and having a top wall, a bottom wall, and an encircling sidewall extending therebetween. A tube has a first end and an opposing second end, the first end of the tube being disposed within the compartment of the container. A nozzle is disposed within the compartment of the container and has at least one outlet, the nozzle being coupled with the tube so that a gas can be passed through the tube and out the at least one outlet of the nozzle. The nozzle is sufficiently buoyant so that when a fluid is disposed within the compartment of the container, the nozzle floats on the fluid.

A hydro turbulator system includes a volute that has a top duct and a bottom duct that allow fluid to enter and exit the volute. An impeller system including a first impeller and a second impeller is positioned within the volute. The first impeller and the second impeller are axially aligned. A motor is operationally connected to the impeller system so that the first impeller and the second impeller rotate upon operation of the motor. Rotation of the first impeller and the second impeller creates successive zones of high pressure and low pressure to agitate and condition fluid within the volute.

A hollow expansion chamber of the present invention is configured to temporarily contain an expansion of bubbles during an aeration process for aerating a liquid, where a chamber body of the expansion chamber has a rounded shape. When moving circumferentially downward along the chamber body starting from a maximum inside diameter, the rounded shape of a bottom portion has a first integral transition that is a tangential transition to a first frustoconical shape. Continuing moving circumferentially downward, the first frustoconical shape has a second integral transition to a cylindrical extension. The cylindrical extension at a distal end has a bottom opening configured to fit within an opened bottleneck. The first frustoconical shape has a minimum angle of 15 degrees relative to a horizontal plane. The second integral transition is a radial second integral transition having an inside surface radius of at least 0.25 inches.

A method is provided for producing fine-bubble water by resonance foaming and vacuum cavitation, and a device for manufacturing each of ultra-fine-bubble water of hydrogen gas having a reducing radical function, ultra-fine-bubble water of air and oxygen gas having an oxidizing radical function, ozone ultra-fine-bubble water having a sterilization function enabled by ozone, and fine-bubble water of nitrogen/carbon dioxide gas for increasing the ability to preserve the freshness of raw agricultural products, livestock products, and marine products.
