A filtration and selective fluidic recovery device comprises a housing having an inlet and an outlet. The housing has an opening extending from the inlet to the outlet and an internal support structure maintained in the opening. At least one planar filtration media is carried by the internal support structure where the media separates feedwater received at the inlet into at least a permeate and a concentrate that separately exit at the outlet.

A multi-effect membrane distillation system includes first and second membrane distillation effects. Each effect (stage) includes a feed channel, a gap, and a vapor-permeable membrane separating the feed channel from the gap. A liquid feed is fed into the feed channel of the first effect via a feed inlet, and the liquid feed is extracted from the first-stage feed channel via a first feed-transfer conduit that delivers the liquid feed to the second-stage feed channel. The feed is extracted from the second-stage feed channel via a second feed-transfer conduit. At least one permeate-extraction conduit is coupled with the first-stage and second-stage gaps and is configured to extract permeate (e.g., pure water) therefrom.

A gaseous component is extracted non-cryogenically from a feed gas containing condensable hydrocarbons. The feed gas is passed first through a module containing polymeric fibers useful for removing water vapor from the gas. The gas is then passed through a module containing polymeric fibers selected such that they remove some, but not all, of the carbon dioxide in the stream. The gas is then passed through a module containing polymeric fibers selected to remove at least some of the remaining carbon dioxide as well as heavy hydrocarbons, defined as C5 and heavier, from the stream. The invention is especially useful in processing raw methane taken from a well, and in producing methane which is relatively free of water vapor, carbon dioxide, and heavy hydrocarbons.

Embodiments relate generally to a filter, for example, for attachment onto a gas detector device or a gas sensor, and attempt to improve the efficiency and service life of the filter. Embodiments typically comprise a dustproof membrane and a waterproof membrane. Some embodiments may also comprise a splash-proof cap and/or features to reduce negative pressure on the filters.

A humidification and selective permeation module in which humidification of a gaseous feed stream and selective permeation of components in the gaseous feed stream using a facilitated-transport membrane occurs within the same unit operation is disclosed. A process for separation of components in a gaseous feed stream using the humidification and permeation module combines continuous humidification of the feed stream and selective permeation using the facilitated-transport membrane.

A water treatment system comprising a pressure vessel, vertically aligned separation elements within the vessel each having at least one porous UF or MF membrane, feed fluid passageways, a permeate fluid passageway, a concentrate removal port, and a biocontactor within the vessel that has biogrowth surfaces surrounding flow paths through the biocontactor. The flow paths have a median ratio of surface area to volume which exceeds 15 cm.sup.1. The pressure vessel also contains a pressure plate with holes which separates the vessel into two chambers, a first chamber containing membrane elements and a second chamber that contains the biocontactor. A sealing means contacting the pressure plate prevents fluid flow between the first chamber and second chamber except through the porous membranes.

An oxygenator apparatus for use in an extracorporeal circuit. The apparatus includes a housing and a membrane assembly disposed within the housing. The membrane assembly includes a first plurality of gas exchange elements disposed in a first zone and a second plurality of gas exchange elements disposed in a second zone. The second zone is arranged concentrically around the first zone. The first and second plurality of gas exchange elements are fluidly open along a body and fluidly separated along a distal end. The first zone is configured to be fluidly coupled to an oxygen source and the second zone is configured to be fluidly coupled to a negative pressure source. A blood flow path includes a generally radial flow through the first zone to add oxygen to the blood and the second zone to separate gaseous micro emboli from the blood through the plurality of gas exchange elements.

Disclosed are apparatus and methods for blood and other biological fluid purification using a membrane with cell containing vascular channel systems and filtration channel systems. Also disclosed are methods of making the apparatus as well as methods of making membranes.

The present invention relates to a gas exchange unit for use in extracorporeal membrane oxygenation (ECMO) or extracorporeal live support (ECLS) according to a method for producing such a gas exchange unit as well as a kit with a gas exchange unit and a humidifying and heating device.

The present invention is directed to a filter assembly for capturing environmental DNA (eDNA), a kit comprising the filter assembly, a method of capturing eDNA using the filter assembly, a method of analysing eDNA captured in the filter assembly, and a method of providing biodiversity data by analysing eDNA collected in the filter assembly.
