Abstract: A method of manufacturing porous fluid treatment elements includes forming a planar structure including a layer of thermally bonded particulate material. The fluid treatment elements are cut from the planar structure. Cutting a fluid treatment element from the planar structure includes moving a cutting tool part in an axial direction relative to the planar structure. The cutting tool part includes a cutting edge defining an edge of an orifice delimited by an inner tool surface extending from the cutting edge. At least a section of the inner tool surface is angled with respect to the axis of movement, such that a size of the orifice decreases in axial direction away from the cutting edge.

Abstract: A method of manufacturing a porous fluid treatment element, e.g. a filter element, includes forming a layered structure having at least two layers and subjecting the layered structure to at least a heat treatment. The step of forming a layered structure includes forming a first layer including particulate matter including at least a binder and applying a second layer including particulate matter including at least a binder directly onto the first layer on a first side thereof. The step of forming a layered structure further includes applying at least one of radiation and heat to at least the first side of the first layer prior to applying the second layer.

Abstract: A device for the treatment of water, in particular a filter device. The device has a cartridge which has a container for receiving treatment agents for water, particularly for receiving filter agents, and a connection head arranged on the container. In addition, a connection element is provided which has a recess for the connection head. At least one locking shaft is provided with which the connection head can be fixed in the connection element. The locking shaft is rotatably mounted and can be rotated from a locking position to an unlocking position and back again. A cartridge with a recess in the connection head is provided.

Abstract: The invention relates to a filter cartridge (1), in particular a suction filter cartridge, in which the inlet region (10) and the outlet opening (20) are arranged in the base region. The outlet opening (20) is connected to the inlet region (10) via a by-pass, which is located in a lower section of the outflow chamber (2a) or below the outflow chamber (2a).

Abstract: An apparatus for treating a liquid having a receptacle for collecting the liquid to be treated and a cartridge for treating the liquid, releasably attachable to the receptacle. The receptacle includes a first locking device and a drain opening for dispensing the liquid to be treated, and has a first axis (L1). The cartridge includes a second locking device and an inlet opening for leading the liquid to be treated into the cartridge. The cartridge has a second axis (L2). The first locking device is provided with a first shaped section and the second locking device is provided with a second shaped section, insertable into each other in an interlocking manner.

Abstract: A container for the filtration of liquid is described, which has a cup and a cover mounted on the cup. The cup is at least partly filled with a filter material and has at least one outlet window for the liquid. The cover has at least one inlet window and at least one outlet window for air, wherein at least the windows have lattice-like structures with lattice openings. The air outlet window has at least one recess extending inward from the plane of the window, which is provided at least partially with at least one lattice structure.
