A separator for removing contamination from a fluid of a heat pump includes a housing having a hollow interior, a separation component mounted within the hollow interior, and at least one turbulence-generating element positioned within the hollow interior adjacent the separation component.

The present invention generally relates to systems and methods for the separation and removal of carbon dioxide from a liquid, for example, seawater. The systems include an extraction system that collects carbon dioxide from the seawater through a medium, and removes carbon dioxide from the medium; the extraction systems comprising a reactor and a membrane. Alternatively, the extraction system includes a reactor, a membrane and a catalyst.

A filtration system effective to filter bacteria, cysts, and viruses, and to alter the surface tension of water. The small scale filter includes a rigid or semi-rigid core having perforations formed therein, and surrounded by one or more layers of filter media formed into a pleat pack filter arrangement.

A system and methodology for the preservation of red blood cells is described in which red blood cells are oxygen or oxygen and carbon dioxide depleted, treated and are stored in an anaerobic environment to optimize preparation for transfusion. More particularly, a system and method for extended storage of red blood cells from collection to transfusion that optimizes red blood cells prior to transfusion is described.

A method of treating a switchable polarity material comprises introducing a first feed stream comprising a solvent and a non-polar form of the switchable polarity material to a first side of a gas diffusion membrane. A second feed stream comprising an acid gas is introduced to a second side of the gas diffusion membrane opposing the first side of the gas diffusion membrane. Molecules of the acid gas of the second feed stream are diffused across the gas diffusion membrane and into the first feed stream to form a product stream comprising a polar form of the switchable polarity material. A treatment system for a switchable polarity material, and a method of liquid treatment are also described.

Provided is a hollow fiber degassing module which includes a hollow fiber membrane bundle obtained by bundling a plurality of hollow fiber membranes in a cylindrical shape and a cylindrical body receiving the hollow fiber membrane bundle and extending in an axial direction and degasses a liquid by supplying the liquid to the outside of the hollow fiber membrane and depressurizing the inside of the hollow fiber membrane, in which a hollow fiber membrane packing ratio which is a ratio of a sum of an apparent cross-sectional area of the hollow fiber membrane with respect to an apparent cross-sectional area of the hollow fiber membrane bundle is in a range of 43% or less.

An apparatus for filtration has a feed of sludge, containing liquid, solids and gases fed into a tank, the tank containing at least one spinning separation filter comprising a filter cone set having a filter screen, and a barrier cone, arranged roughly in parallel, and defining a conical workspace between them, the conical workspace having a peripheral opening to the tank and a central opening communicating with the interiors of one or more hollow shafts supporting the barrier cone and the filter cone, the upper shaft supporting the barrier cone having an upper axial channel for the exit of gases, the lower shaft supporting the center of the filter cone having a lower axial channel for the exit of liquid or oil, motor means for producing rotation in said at least one spinning separation filter, and a filtrate liquid reservoir located underneath the filter cone for capturing the filtrate passing through the filter screen.

An aircraft fuel tank inerting system and a method of inerting an aircraft fuel tank. The aircraft fuel tank inerting system having an on-board inerting gas generation system arranged in fluid communication between a fuel tank vent system and an aircraft fuel tank.

In one example, a liquid-gas separator includes a composite membrane to pass a gas but not a liquid at a first pressure difference across the membrane and to block the gas passing back through the membrane at a second pressure difference smaller than the first pressure difference.

A method including acidifying a solution including dissolved inorganic carbon; vacuum stripping a first amount of a carbon dioxide gas from the acidified solution; stripping a second amount of the carbon dioxide gas from the acidified solution; and collecting the first amount and the second amount of the carbon dioxide gas. A system including; a first desorption unit including a first input connected to a dissolved inorganic carbon solution source to and a second input coupled to a vacuum source; and a second desorption unit including a first input coupled to the solution output from the first desorption unit and a second input coupled to a sweep gas source.
