Abstract: A liquid treatment device includes a container section defining a container for holding liquid to be treated. The container section includes at least part of a body, the body including at least one wall forming at least a bottom of the container. At least one first liquid-permeable window through the wall forming the bottom of the container is provided. The device also includes a liquid treatment section, including a cavity surrounded by a cavity side wall forming at least one second liquid-permeable window for treating liquid passing through it. The cavity side wall is sealingly joined to a liquid-impermeable wall section along the circumference of the cavity side wall and around a liquid path through the cavity and the first liquid-permeable windows at an end of the cavity side wall proximal to the at least one first liquid-permeable windows. The liquid-impermeable wall section is an inseparable part of the body.

Abstract: A method of manufacturing a cartridge for a fluid treatment system, wherein the cartridge includes a housing defining at least one chamber for a fluid treatment medium, includes providing a cartridge housing part including at least one wall defining at least one opening closable by a filter element. The filter element includes a porous body for at least mechanically filtering fluid flowing into the filter element through at least one first surface area of the filter element, through the porous body and out through at least one second surface area of the filter element. The filter element includes a rim, covering at least a peripheral face of the porous body so as to frame the first and second surface areas. The filter element is combined with the cartridge housing part so as to close at least one of the at least one openings by bonding the rim to the cartridge housing part.

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 method of manufacturing a cartridge (104; 204; 304; 404; 504; 604; 704; 804) for a fluid treatment system (101; 401), wherein the cartridge (104; 204; 304; 404; 504; 604; 704; 804) includes a housing defining at least one chamber for a fluid treatment medium, includes providing a cartridge housing part (212; 312; 512; 612; 712; 812) including at least one wall (217; 313; 517; 613; 713; 813) defining at least one opening (218; 318; 518; 618; 718; 818) closable by a filter element (219; 319; 519; 619; 719; 819). The filter element (219; 319; 519; 619; 719; 819) is provided.

Abstract: A device for treating a liquid, including a container for collecting the liquid to be treated, including a first fastening unit which has the property that the unit develops a force of attraction under the action of a magnet or has the property of a magnet, and a cartridge for treating the liquid and which can be detachably fastened to the container, including a second fastening unit which has the property that the unit develops a force of attraction under the action of a magnet or has the property of a magnet. The first fastening unit and the second fastening unit interact such that the cartridge can be detachably fastened to the container.

Abstract: A filter unit for treating water, having a first plate-shaped filter element and at least one second plate-shaped filter element. The first and second filter elements are mutually spaced from each other and define an intermediate space. Each of the first arid second filter elements extends, with reference to a Cartesian coordinate system, along a first spatial axis to a considerably lesser extent than along the two remaining spatial axes such that the element has a layer thickness (?). Flow can take place through the first and second filter elements along a path that corresponds to the layer thickness.
