The invention relates to an apparatus for separating blood and at the same time an apparatus (1) for absorbing blood (19) and separating components such as blood plasma, as a sample liquid (2), having a feed device (13) for receiving the blood (2), a separating device (15) for separating blood components as the sample liquid (2), a channel (3) which takes up the sample liquid (2) preferably exclusively by capillary forces and a fill device for filling the channel (3) with sample liquid (2) in an inlet or feed region (18) of the channel (3), wherein the separating device (15), particularly a membrane, is domed, more particularly convexly shaped and projects with the apex of the convex shape into the filling device in the direction of filling.

An outside-in liquid purification system includes a housing and a cartridge. The housing defines an interior space and includes an inlet, an outlet, walls extending between a top side and a bottom side, and an unfiltered volume. The cartridge is disposed within the interior space and includes a top cap adjacent the top side of the housing configured to direct liquid that enters the interior space to the unfiltered volume and a filter having an annular shape and extending between the top cap and the bottom side of the housing such that no portion of the unfiltered volume is below the filter with the filter defining a hollow vertical column such that liquid flows from the unfiltered volume through the filter into the column and then downward out of the housing through the outlet.

A filter element for use in a filter disc, wherein a plurality of filter elements are arranged on a rotor shaft in a manner allowing liquid communication between the inside of the filter elements and the inside of the rotor shaft. The filter element has at least one passage in an edge structure for liquid communication between the inside of adjacent filter elements when the filter elements are assembled forming a filter disc. The passage has different passage area along the edge structure.

A flow distributor for a fluid flow entering a deceleration vessel from an inlet conduit comprises a plurality of spaced vanes arranged extending substantially parallel to each other across a width of the distributor and being angled from the upstream to the downstream end so as to form flow channels therebetween to direct flow outwardly away from a central portion of the distributor.

A filter element for use in a filter disc, wherein a plurality of filter elements are arranged on a rotor shaft in a manner allowing liquid communication between the inside of the filter elements and the inside of the rotor shaft. The filter element has at least one passage in an edge structure for liquid communication between the inside of adjacent filter elements when the filter elements are assembled forming a filter disc. The passage has different passage area along the edge structure.

A screen intake has a central body with two screens attached on either end. Each of the screens has an interior that communicates with a hollow of the body via flow modifiers. These flow modifiers include one or more pipes disposed in the interior of the screens and through passages in ends of the body. A flow control support device disposed within the body supports the body's sidewall and divides the hollow into at least two portionseach communicating with flow from one of the flow modifiers. The device can include one or more plates disposed adjacent one another within the internal hollow with a peripheral edge attached to an inside of the body's sidewall. At least one of the one or more plates can be solid, or one or more of the plates can define openings therein allowing passage of at least some fluid therethrough.

A filter device includes a housing with an end part and a side wall and containing an axially arranged array of filter elements, such as ceramic elements. An inlet in the end part supplies fluid to the filter elements and an outlet in the side wall is provided for transporting filtered fluid from the housing, the side wall of the filter device being provided with a cleaning duct for supplying cleaning fluid to the filter elements via the side wall. The cleaning duct 6 includes a distal channel portion 15 having a relatively small diameter D1 and a proximal portion 16 adjacent the side wall having a relatively large diameter D2. A number of partitions 36, 37 extend in the proximal portion from a position at or near the sidewall towards the distal channel portion 15 at an angle () to a center line 20 of the cleaning duct 6.

The passage has different passage area along the edge structure.

This invention relates to a modular purification system having a disposable sump assembly and an improved flow distribution plate. The system is readily adaptable to a variety of configurations without the need for repiping or replumbing of the installation, and lends itself to the use of multiple purification techniques.

A filter cartridge for the filtration of liquids, which filter cartridge is characterized in that at least one compression element is arranged between two pressure elements, each of which is pressed into a respective filter chamber section by the expansion movement.
