A system may include a nanobubble generator that uses a shearing force applied by a fluid received through a fluid inlet and a negative pressure applied to an outlet by a pump to provide a vacuum-assisted shear flow nanobubble generator system. In some implementations, the system may include a nanobubble generator including a porous component including a chamber coupled to receive a gas and including a surface having a plurality of gas-permeable openings. The nanobubble generator may include an inlet and an outlet on opposing sides of the porous component to direct the fluid across the openings. The system may include a pump to apply a negative pressure to the outlet of the nanobubble generator. The negative fluid pressure and the fluid flow across the openings cooperate to form nanobubbles at low injected gas pressures, increasing the efficiency of production of nanobubble solutions with pressure sensitive gasses, such as ozone.

A transportable system for generating aqueous ozone solution includes a wheeled frame and an aqueous ozone solution supply unit that is coupled to the wheeled frame. The aqueous ozone solution supply unit is configured to produce an aqueous ozone solution onsite by generating and injecting ozone into water received from an onsite water source. The transportable system further includes an outer enclosure configured to surround at least a portion of the wheeled frame and configured to contain the aqueous ozone solution supply unit. The outer enclosure is also configured to store one or more external components for the aqueous ozone solution supply unit and one or more cleaning accessories when the aqueous ozone solution supply unit is being transported via the wheeled frame.

A system, method, and apparatus for oxygenation of a source of water, to increase the dissolved oxygen content of water. Aspects of the present invention harnesses and directs the power of water flowing through the system to extract oxygen present in air, rather than relying on the injection of gas or using other mechanical means. The water oxygenator is formed as an elongate cylindrical tube having a water inlet at a first end, a water outlet at a second end, and an air inlet proximal to the first end. The elongate cylindrical tube has an outer sidewall defining a mixing chamber within an interior cavity of the water oxygenator. The mixing chamber includes a plurality of baffles that are disposed in a spaced apart relation along a longitudinal length of the interior cavity.

A vortex flow inducer has inducer body with an interior end, an outer end and a length extending there between, and a longitudinal axis extending between the interior and the outer ends. A flow passage extends between the interior and outer ends of the inducer body. The flow passage has an inlet at the outer end and an exit at the interior end. The flow passage is swept latterly toward a side of the inducer body in a direction from the outer end toward the interior end such that the exit is latterly offset from the longitudinal axis. The interior end of the inducer body has a concave curvature. The swept flow passage and the curved interior end induce a vortex flow in a fluid flowing through the flow passage as it exits the flow passage and into a flow passage of a conduit the that extends at an angle relative to the longitudinal axis of the inducer body.

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 ultra-fine bubble-containing liquid generating apparatus (UFB-containing liquid generating apparatus) includes a dissolving unit that generates a gas dissolving liquid and an ultra-fine bubble generating unit that generates ultra-fine bubbles in the gas dissolving liquid. Additionally, the UFB-containing liquid generating apparatus includes a temperature controlling unit that controls at least one of temperatures of the dissolving unit and the ultra-fine bubble generating unit such that the temperature of the ultra-fine bubble generating unit is equal to or lower than the temperature of the dissolving unit.

A manufacturing apparatus for a solidified matter of an ultra-fine bubble (UFB)-containing liquid includes: a UFB generating unit that generates the UFB-containing liquid; and a cooling unit that generates the solidified matter of the UFB-containing liquid by cooling the UFB-containing liquid. The cooling unit cools the ultra-fine bubble-containing liquid such that a first solidified portion and a second solidified portion at a lower ultra-fine bubble concentration than that of the first solidified portion are formed in the solidified matter.

Provided is a UFB generating apparatus capable of manufacturing an ozone UFB-contained liquid with high purity and quality.
