A gas-liquid separator includes: a gas-liquid separation tank; a gas-liquid introduction pipe configured to introduce a gas-liquid two-phase flow into the gas-liquid separation tank, the gas-liquid introduction pipe extending in the gas-liquid separation tank; a spray nozzle configured to spray pure water toward a liquid that has been collected on a bottom of the gas-liquid separation tank; a drain pipe communicating with a liquid discharge outlet provided in the bottom of the gas-liquid separation tank; and an exhaust pipe communicating with a gas discharge outlet provided in a side wall of the gas-liquid separation tank. The gas discharge outlet is located above a lower end of the gas-liquid introduction pipe.

A deaerator includes a tank, a spray unit, a steam supply unit, a bleed unit and a discharge pipe. The spray unit is disposed at an upper portion of the tank and configured to supply water to the tank. The steam supply unit is disposed inside the tank to supply steam to the tank. The bleed unit is disposed at the upper portion of the tank and adjacent to the spray unit. The bleed unit is configured to bleed air from an inside of the tank. The discharge pipe is configured to discharge water without air to an outside of the tank.

Methods and apparatuses are provided for deaeration of a liquid. Liquid may be impinged onto an inclined baffle and forced through a first plurality of apertures that direct the liquid in one or more directions away from one or more outlets of a reservoir. The liquid may be passed through a second plurality of apertures. Flowing the liquid as described promotes a circuitous route of travel and provides a residence time inside of the reservoir that promotes release of entrained air.

A surface foam diffuser and digester tank system prevents and/or suppresses the formation of foam during digestion. The system includes a first nozzle disposed above a top surface of the at least partially liquid contents, a splash plate positioned adjacent to the first nozzle outlet, and a second nozzle disposed below the top surface of the at least partially liquid contents for suppressing foaming in the large processing tanks. The system nozzles each have an inlet for receiving pressurized liquid and an outlet for ejecting a liquid stream into the tank, the depth of the second nozzle and the direction of the liquid stream there from being such that rotation of the top surface is facilitated. The spray of the first nozzle, as dispersed by the splash plate, reduces foam on at least a portion of the top surface, with the rotation of the top surface bringing each portion of the top surface to eventually fall within the reducing spray.

Devices, systems, and methods for high capacity degassing of dissolved gases and gas bubbles from fluid such as a dialysate are provided. The devices, systems, and methods can include a degassing vessel with at least two degassing chambers. The fluid can be degassed in a first degassing chamber and recirculated through a second recirculating degassing chamber to remove a desired amount of gas such as carbon dioxide.

Disclosed herein are advantageous phase separator devices, and related methods of fabrication and use thereof. The present disclosure provides improved phase separator devices for phase separation of feedstreams, and improved systems/methods for utilizing and fabricating the phase separator devices. More particularly, the present disclosure provides porous (e.g., three-dimensional gradient porous) phase separator devices for phase separation of fluid mixtures (e.g., to separate a two-phase fluid mixture) to a first fluid phase flow (e.g., to a liquid flow) and to a second fluid phase flow (e.g., to a gas flow). At least a portion of the phase separator devices of the present disclosure can be fabricated via machining, powder metallurgy (e.g., sintering), and/or produced utilizing additive manufacturing techniques.

The present invention relates to a nozzle for an air trapping device configured to remove air from a fluid, the nozzle comprising a body having an input opening configured to receive the fluid and an output opening configured to distribute the fluid along an edge of the output opening, wherein the edge comprises a control element configured to reduce surface tension of the fluid. The present invention further relates to an air trapping device configured to remove air from a fluid and comprising the nozzle.

A trihalomethane (THM) and volatile organic compound (VOC) removal system includes: a storage vessel; a fluid inlet on the storage vessel where fluid enters said storage vessel; a fluid outlet on the storage vessel where fluid exits said storage vessel; and a fluid fitting on said storage vessel. Fluid leaves the storage vessel via an inlet conduit attached to the fluid fitting and flows through a pump and passes through a venturi aspirator, and returns to the storage vessel through an outlet conduit attached to the storage vessel.

A gas-liquid separator includes a housing having a first housing portion defining a first housing volume and a second housing portion defining a second housing volume. The gas-liquid separator includes a plate positioned at least partially within the first housing volume. The gas-liquid separator includes a first impaction media positioned against the plate. The first impaction media extends in a first direction. The gas-liquid separator includes a second impaction media positioned against the plate. The second impaction media extends in a second direction, different than the first direction.

A device (100) for aeration of and separation of carbon dioxide from a fluid is disclosed. The device comprises at least a first and a second screen gear (101,102) said first and second screen gear (101,102) comprising several screen windows (203) in the form of openings. The shape and/or distribution of said screen windows (203) on said first and second screen gear (101,102), when said first and second screen gear (101,102) are connected, is such that at least 20%, preferably at least 25%, more preferably at least 30%, of the screen windows (203) of the first screen gear (101) are asymmetrically distributed in relation to the screen windows (203) of the second screen gear (102), asymmetrically distributed implying that the edges surrounding the screen windows of the first screen gear are not 100% overlapping the edges of the screen windows of the second screen gear when the first and second screen gear are connected and seen from above.
