Embodiments of a process for treating a fluid are provided. The process for treating a fluid includes supplying a first fluid to a circulating chamber and introducing a first gas to the first fluid. A portion of the first gas is dissolved in the first fluid and a portion of the first gas is held in a head space portion of the circulating chamber. The process further includes mixing a portion of the first fluid drawn out from the circulating chamber and a portion of the first gas drawn out from the head space portion to form a mixture. The process further includes spraying the mixture back into the circulating chamber by a two-fluid nozzle. In addition, the first gas is further dissolved into the first fluid to form a high conductivity fluid. The process further includes draining the high conductivity fluid from the circulating chamber.

The present invention discloses a system for introducing a gas into a contained media such as a pond or lake. Water is removed from the media, gas introduced, and then the water removed to the contained media.

A low energy apparatus to aerate liquid in a tank using pumped liquid flow over bubble aerators operating at low air pressure near the tank surface, with the flow of liquid and entrained bubbles then being directed through pipes at speeds sufficient to carry the bubbles to the bottom of the tank where the bubbles are released to rise to the top of the tank, infusing the liquid in the tank with air.

Provided is an ultrafine bubble generation device. A device 10 includes a rotary blower 31a, a rotary mixer 11, and a bubble shear filter 21. The rotary mixer 11 includes a hollow part 13 including a vertex X inside, an inflow hole 12 for introducing a fluid and a discharge hole 16. In an inner wall surface of the hollow part 13, a groove 14 having a spiral shape for the fluid introduced from the inflow hole 12 is provided, and the discharge hole 16 is provided away from the vertex X of the spiral shape on an axis of the spiral shape. The bubble shear filter 21 is provided with a hollow part inside, and includes an inflow hole 24 for introducing the fluid into the hollow part, and a discharge hole 26 for discharging the fluid. The hollow part is tubular, a plurality of plate-like thin plates 22 and 23 are arranged perpendicularly to a central axis of the hollow part such that the central axis passes through a center point of each circular plate, adjacent thin plates are provided with a plurality of openings and a plurality of pointed end portions, and a pointed end portion 25a and an opening 25b of the adjacent thin plates are arranged to face each other.

The present invention is directed to a fluid mixing system. In an embodiment, the fluid mixing system includes a first vessel; a second vessel disposed within the first vessel; a mixer disposed outside of the first vessel in fluid communication with the second vessel; and a media introduction port disposed outside of the first vessel in fluid communication with the mixer.

A system and method for mixing and dispensing two substances are provided. The system includes: a first substance a first container for containing a first substance, a second container for containing a second substance, a feeding tube, and a pumping system connected to the first container, the second container, and the feeding tube; wherein the system comprises at least three modes of operation: combining the first and second substances into one combined substance, mixing the combined substance, and dispensing the mixed substance; and wherein the pumping system is adapted to perform the at least three modes of operation and dispense the mixed substance to the feeding tube.

A system for producing homogenized oil field gel including a power unit, a control system, a feed tank, a hopper, and a piping assembly that includes inlet and outlet manifolds, centrifugal pumps, and metering devices for filling the feed tank and handling a discharge of oilfield gel. The system further includes a powder hydration component and liquid chemical equipment. The method for producing homogenized oil field gel includes a guar powder procedure including a controlled sequence for starting and stopping a venturi mixer in a hydration unit. The method for producing homogenized oil field gel further includes a liquefied gel concentrate procedure including a metering and chemical injection procedure for mixing a liquefied gel concentrate.

Initial liquid containing fine bubbles is produced by mixing water and air (step S11). Fine bubbles have diameters of less than 1 μm. The density of bubbles in the initial liquid is measured (step S13), and when the measured density is less than a target density (step S14), the initial liquid is heated and reduced in pressure so that the liquid is vaporized (step S15). As a volume of the liquid decreases, the density of fine bubbles increases, and high-density fine bubble-containing liquid is easily obtained. Alternatively, by increasing the density of fine bubbles in the initial liquid with using a filter that does not pass all fine bubbles, high-density fine bubble-containing liquid is easily acquired (step S15). When the density of bubbles in the initial liquid is greater than the target density, the initial liquid is diluted (step S16).
