A system and method are provided in at least one embodiment to process water to produce gas that can be separated into at least two gas flows using a water treatment system having a disk-pack rotating in it to cause out gassing from the water. In a further embodiment, the method and system use the gas released from the water to produce substantially fresh water from the processed salt water.

A system for separating a flow of matter is shown and described. The system includes one or more flow separation devices, one or more surgical instruments, and one or more suction sources. In some embodiments, the flow of matter comprises biological material. In some embodiments, the flow of matter comprises surgical waste.

A system and method for removing gas bubbles from fluid. An active filter apparatus forces the bubbles to the center of the filter, while a pump supplies fluid to the filter.

Provided are degasification devices and methods of degasifying a liquid. Methods of degasifying a liquid can include filling a liquid chamber with a liquid; increasing an internal volume of the liquid chamber to generate a vacuum within the liquid chamber; applying one or more pressure waves to the liquid in the liquid chamber to accelerate the formation of a plurality of gas bubbles which rise to the surface of the liquid and release gas within the plurality of gas bubbles into a space above the liquid in the liquid chamber; and decreasing the internal volume of the liquid chamber to force the gas through a vapor outlet of the liquid chamber, wherein a degassed liquid remains in the liquid chamber.

A method for removing gas from a froth by supplying at least a portion of the froth from a vessel into a housing, providing a flow of fluid through the housing, introducing the froth into the fluid such that at least a portion of the gas in the froth is removed from the froth and entrained in the fluid to form a mixture of fluid and entrained gas and subsequently delivering the mixture to the vessel and/or another location within a processing circuit.

Devices for the removal of gases and/or volatilizable contaminants from liquids are described. In one example device, a liquid fluid containing dissolved gases and/or volatilizable contaminants are passed through at least one local constriction in a flow-through chamber at a sufficient pressure and flow rate to create cavitation bubbles in the liquid flow. The dissolved gases and/or volatilizable contaminants migrate into the cavitation bubbles. The velocity of the liquid flow is then reduced, which allows for the cavitation bubbles in the liquid flow to coalesce. The velocity of the liquid flow can then be reduced further, resulting in additional coalescing of the cavitation bubbles. The cavitation bubbles that contain the gases and/or volatilizable contaminants can then be separated from the liquid flow. The separation generally leaves a liquid flow product that may have a concentration of one or more gases or volatilizable contaminants lower than the starting liquid flow.

An apparatus for reducing bubbles in liquid includes: a bubble elimination structure including a plurality of bubble breaking elements being used to reduce the bubbles in the liquid, an axial direction of each bubble breaking element being consistent with a liquid flow direction; and a spiral structure configured to generate a spiral movement of the liquid around the liquid flow direction to concentrate the bubbles in the liquid in the center of the liquid. The liquid flows through the spiral structure before flowing through the bubble elimination structure.

A fuel deoxygenation system has a deoxygenator, an ultrasound transducer, and a control. The ultrasonic transducer is operable to direct ultrasonic waves into a flow passage for a fuel connected to the deoxygenator. A gas turbine engine and a method are also disclosed.

An apparatus for removing a gas in an immersion ultrasonic process is provided. The apparatus, in the form of an immersion ultrasonic transducer holder apparatus, has a body with a first end, a second end, a plurality of sides, and a hollow interior cavity portion. A holder portion with an exterior end and an interior end is formed through the first end, and holds one or more immersion ultrasonic transducers. A sloped inner face having a base end with a knife-edged perimeter is adjacent the interior end of the holder portion. The sloped inner face has an upward sloped surface extending from the base end to an evacuation end. One or more evacuation ports are formed through the first end, and adjacent the evacuation end. When the apparatus is used in the immersion ultrasonic process, the knife-edged perimeter, sloped inner face, and evacuation ports facilitate removal of the gas.
