A filter assembly that includes a water separator as part of the filter assembly. The water separator is arranged in the filter assembly and includes a filter element that is provided with a hydrophobic medium through which fuel/lubricant can pass through. The filter assembly also includes a water separator positioned downstream from the filter element. During the operation of the filter assembly, the water separator causes the water in the fuel to be separated and accumulate on the hydrophobic surface of the water separator and, due to the gravity, allows the water to flow downwards along the surface of the water separator into a water collection/sedimentation chamber where it can be evacuated from the filter through one or more passageways.

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 for a non-plumbed appliance is provided. The filter includes a filter housing having a sidewall extending along a longitudinal direction between a first end wall and a second end wall. A flow distribution channel is also defined by the sidewall of the filter housing, the flow distribution channel extending outwardly from the sidewall along the radial direction and along the longitudinal direction between the flow aperture and the first end wall of the filter housing. The flow distribution channel equalizes the pressure gradient on the outer surface of the filter media, resulting in an improved flow pattern, increased clogging resistance, and improved filter performance capacity.

A filter for a non-plumbed appliance is provided. The filter includes a filter housing defining a filter chamber. A filter inlet and a filter outlet are positioned along a bottom portion of the filter housing, and filter media is positioned within the filter chamber to remove contaminants from water flowing through the filter media. A divider wall is positioned within the filter chamber to direct the flow of water through a flow aperture at a top portion of the filter chamber, such that the filter chamber remains filled with water during operation. As a result, the filter media remains completely submerged, thereby improving filtration performance, reducing pressure drop, and more evenly depleting the filter media.

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.

The invention relates to an apparatus for separating blood, more particularly an apparatus (1) for absorbing blood (19) and separating blood components, e.g. blood plasma, as a sample liquid (2). Said apparatus (1) comprises a feeding device (13) for absorbing the blood (2), a device (15) for separating blood components as a sample liquid (2), a duct which preferably absorbs the sample liquid (2) exclusively by means of capillary forces, and a device for filling the duct (3) with sample liquid (2) in an inlet or feeding zone (18) of the duct (3). The separating device (15), in particular a membrane, is curved, especially convexly shaped, and the apex of said curved, especially convex shape projects into the filling device.

A filter unit is disclosed that increases solids loading capacity, decreases specific flowrate during filtration, and improves backwash effectiveness. A flow shaping plate and/or flow diverting member are used to reduce flow entrance effects during reverse, backwash flow through the filter unit.

An apparatus is provided for a powerplant. This powerplant apparatus includes a fluid filter assembly with a filter housing. The filter housing extends axially along an axis between a housing first end and a housing second end. The filter housing includes a mount and a sidewall. The mount is connected to the sidewall. The mount includes a flange, an attachment and a pilot. The flange projects radially out from the sidewall and the attachment to a flange distal outer end. The attachment extends axially between the flange and the pilot. The attachment is configured with an external threaded section. The pilot projects axially out from the attachment to the housing first end. The pilot includes a cylindrical external surface located radially inboard of the external threaded section. An axial length of the pilot is greater than an axial length of the attachment.

Liquid filter systems, flow spreaders and filter elements for improving flow are provided. A liquid filter system can comprise: a chamber having an inlet at its upper end and an outlet at its lower end; a filter element having a hollow interior volume, the filter element arranged in the chamber to filter the liquid flow by passage into the low interior volume to the chamber outlet; and a flow spreader having an inclined surface forming an apex, the flow spreader arranged at the upper end of the filter element to receive a columnar liquid flow from the inlet of the chamber at the apex of the inclined surface and to provide an annular liquid flow past the upper end of the filter element into an annular gap between the filter wall of the filter element and the lateral wall of the chamber.
