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 system and method for recycling gas in a backwash process is provided. The backwash process removes contaminants from a bed of filtration media. The method includes generating a mixed liquid-gas stream from the backwash process, withdrawing the mixed liquid-gas stream from the backwash process, separating the mixed liquid-gas stream into a liquid and a gas, and recycling at least a portion of the separated gas to the backwash process.

A method and system for separating multicomponent fluids into components having different buoyancies. A flow shaping member has a helical channel that imparts a helical motion to the fluid, and a separation chamber for separating the moving fluid into a helically moving heavier flow portion and a more buoyant portion along the central axis. A flow receiving member has a first collection horn with a mouth arranged to collect the higher buoyancy fluid and direct the fluid to an outlet. At least one other fluid passageway for carrying lower buoyancy fluid has an inlet surrounding of the collection horn, and directs the fluid to a separate outlet at an end of the separator. Additional collection horns can be arranged concentrically around the first collection horn to collect intermediate buoyancy flows. Cascaded fluid separators can concentrate the higher buoyancy fluid or the denser fluid.

An in-line continuous flow liquid-gas separator-pump includes a housing, a rotor, a plurality of tubular flow passages, and a plurality of gas flow passages. The rotor includes a rotor first end, a rotor second end, an outer surface, and an inner surface that defines an inner chamber in fluid communication with the purge gas outlet. The tubular flow passages are formed in the rotor and extend between the rotor first end and the rotor second end. Each tubular flow passage includes a fluid inlet that is disposed adjacent the rotor first end and in fluid communication with the liquid/gas inlet, and a fluid outlet that is disposed adjacent the rotor second end and is in fluid communication with the liquid outlet. The gas flow passages are formed in the rotor, and each provides fluid communication between one of the tubular flow passages and the inner chamber.

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.

An apparatus for gas and solids separation from down-hole fluids having an inner tube and an outer tube disposed about the inner tube. The annular region between the tubes contain a plurality of chambers, separated by fluid barriers. The chambers include an intake chamber to receive fluids from outside of the outer tube through an orifice, and processing chambers. Fluid communication between the intake and processing chambers is restricted to fluid flow through sets of tubes. Fluid communication between a lowermost processing chamber below the intake chamber and a lower processing chamber above the intake chamber is restricted to fluid flow through the inner tube. A block restricts fluid communication within the inner tube to other chambers above the intake chamber. Orifices in the inner tube of the processing chambers on either side of the block provide fluid communication across the block.

A fluid separator includes a body, an inlet, a first outlet and/or a second outlet. The first outlet may include a vortex finder that may have a convergent-divergent configuration. The second outlet may include or may be connected to a pressure relief valve. At least a portion of the pressure relief valve may be disposed in the vortex finder. The pressure relief valve may be disposed entirely outside of the vortex finder. The vortex finder may include a divergent section and a convergent section. In embodiments, the divergent section may be at least twice as long as the convergent section, a taper angle of the convergent section may be at least twice as large as a taper angle of the divergent section, and/or an axial length of a portion of the vortex finder extending into the body may be at least 1.5 times a diameter of the inlet.

A gas-containing liquid generating apparatus according to an aspect of the present invention includes a gas/liquid mixing module configured to mix a gas and a liquid to generate a gas-containing liquid, a first injection module configured to inject the gas-containing liquid supplied from the gas/liquid mixing module, and a second injection module configured to inject the gas-containing liquid supplied from the first injection module to generate bubbles in the gas-containing liquid, wherein the first injection module includes a containing portion configured to contain the gas-containing liquid, a cylindrical portion having a channel configured to inject the gas-containing liquid into the containing portion, and a protruding portion provided on an inner wall surface of the cylindrical portion so as to protrude into the channel.

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.
