The present invention relates to a microfiltration container (2), comprising a base (1) for a microfiltration container (2), said container being adapted to contain at least one microfilter (3) and create fluid passages which force a fluid, passing from a fluid inlet (4) to a fluid outlet (5), to pass through said microfilter (3); wherein said base (1) is a monolithic body, i.e., made in a single piece; wherein a microfilter seat (6) is obtained in said base (1) for accommodating and securing said at least one microfilter (3); wherein at least a first valve half-chamber (7) is obtained in said base (1), adapted to accommodate a first movable valve element (8) adapted to move from a valve opening position to a valve closing position; wherein said at least a first valve half-chamber (7) comprises at least a first abutment surface (9) for sealing said movable valve element (8); wherein said microfiltration container (2) comprises a container bell (28); wherein said container bell (28) comprises a cylindrical bell body (42) in which a first lower end thereof is sealingly connectable to said base (1) and in which an upper opposite end thereof is closed by a bell cap (43).

The present disclosure describes a flow-electrode capacitive deionization (FCDI) desalination system and method of use. An FCDI desalination system is described employing one or more FCDI cells equipped with two coaxially oriented membranes mounted within a column housing capped with two end caps, each end cap comprising two carbon slurry ports and one water port. The column is lined with a chargeable sleeve capable of receiving a positive or negative charge. The annular space between the chargeable sleeve and the outside surface of the outer concentric membrane creates a flow path for a first carbon slurry to pass therethrough. The space between the inside surface of the outer concentric membrane and the outer surface of the inner concentric membrane creates a flow path for the saline water to be treated. The space within the inner annular portion of the inner concentric membrane creates a flow path for a second carbon slurry and contains a chargeable rod or wire capable of receiving an opposite charge. The first and second opposed end caps on the column are outfitted to continue these independent flow paths. As the saline water travels through its flow path, its salt ions are removed through the coaxial membranes via the two carbon slurries.

A ceramic membrane filtration assembly comprising a membrane assembly extending from a first membrane assembly end to a second membrane assembly end, where the membrane assembly is defined by a membrane assembly length, the membrane assembly including at least one membrane. At least one of the membranes have channels therein, and at least one channel has channel ends. The filtration assembly further includes at least one sealing device coupled with the membrane assembly adjacent to at least one of the first and second membrane assembly ends, where the sealing device has an inner and outer perimeter. The sealing device has a sealing feature disposed along the outer perimeter, and the inner perimeter of the sealing device is sealed with a portion of the membrane assembly.

The filter device includes: a funnel having an inlet through which the liquid sample is introduced and an outlet having an opening area smaller than an opening area of the inlet; a filter container to which a tip portion which includes the outlet of the funnel is inserted and a filter that collects an object contained in the liquid sample; a rubber plug having a through-hole serving as a flow path for the liquid sample that has passed through the filter; and a filter fixing tool that abuts on the filter container to support the filter container and that presses the filter container against the rubber plug.

A humidifier having a housing that extends along an axial direction, the housing having a first inlet, a first outlet, a second inlet and a second outlet, and a membrane unit being arranged in the interior of the housing. The first inlet and the first outlet are in flow connection with each other by means of a first flow path, and the second inlet and the second outlet are in flow connection with each other by a second flow path. The membrane unit is cylindrical and has a plurality of hollow fiber membranes arranged side by side. The membrane unit is outwardly surrounded at least in part by a first chamber, and the first chamber is outwardly surrounded at least in part by a second chamber separate from the first chamber. The first chamber and the second chamber are in flow connection with each other via one or more throttle slots.

A self-contained filtration assembly with a self-contained filtration cassette therein. The cassette may be formed from one or more layers membranes and spacers (spacers, screens, or combinations thereof) all having the same general shape. The cassette may have a feed inlet path and a retentate outlet path extending through the layers of the cassette within the perimeter of the cassette, and a permeate outlet path between the cassette exterior and the interior of the cassette housing. The housing may have a generally circular or elliptical cross-section. A clamping assembly may hold together the components of the housing, and may be elongated in a direction along the flow path of the feedstream through the cassette. Various port-defining zones defined in the layers of the cassette may be sealed in a manner facilitating assembly of the cassette as well as isolation of the flow paths therein.
