Abstract: A system for conditioning a liquid such as water, includes a first holder of a medium for treating liquid, the medium in the first holder including an ion exchange material loaded with at least a first counter ion species, and a second holder of a medium for treating liquid, the medium in the second holder including an ion exchange material loaded with at least a second counter ion species of the same polarity as the first. The media in the first and second holders are configured to exchange at least one of the first and second counter ion species for ions in the liquid to a different extent. The system is arranged to lead a first fraction of the liquid to be treated through only the first of the first and second holders and a second fraction of the liquid to be treated through at least the second of the first and second holders.

Abstract: A container having a top wall, which has at least one top wall region that can be perforated to form a feed opening for feeding a liquid; a bottom wall, which has at least one bottom wall region that can be perforated to form an outlet opening; and at least one chamber, which is surrounded by chamber walls and in which a base product and an adjustment element are located. The adjustment element is arranged such that it can be moved from an idle position to a working position and, when in the working position, opens at least one chamber wall. A chamber wall has at least one opening, on or in which a component of the adjustment element is detachably fastened when in the idle position. The component of the adjustment element closes the opening in the chamber wall.

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.

Abstract: The invention relates to a filter cartridge (1) which comprises a firmly fixed lid (10) and has a long service life. Said lid (10) is embodied in such a way that the bottom (11) of the lid extends towards the peripheral wall (3) of the cartridge container to join the lateral wall (16) of the lid, by means of an inwardly curved edge section (14), the curved edge section (14) and the lateral wall (16) in the form of a strip joining in the forming region to form an inwardly tapered common wall section (15). In this way, the region fixing the lateral wall (16) to the peripheral wall (3) is subjected only to a tensile load, minimizing the risk of shear fracture, and the inner pressure in the region of the common wall section (15) presses the wall section against the peripheral wall (3), thus exerting an additional sealing force.

Abstract: The invention describes an apparatus for the filtration of liquids and an associated filter cartridge 100, wherein the quantitative flow through the filter cartridge can be reduced and set in a simple way. The apparatus is characterized in that at least one throttling device 200, 200? is arranged between the outlet opening 113 of the filter cartridge 100 and the outflow opening 17 of the receiving chamber 14.

Abstract: It is described a method of measurement of the volume VD of the flow-rate of electrically conductive liquids the conductivity of which is at least codetermined by at least one parameter p, wherein the liquid flows through a vessel having a predetermined shape, and wherein the respective filling volume Vo is determined by at least one measured value x, which is measured by an electrical conductivity measuring device comprising electrodes, wherein the vessel is filled in succession and then is emptied through its outlet, through which the filling heights h are constantly changing. At least one reference table comprising calibration measured values xR and filling volumes Vo belonging to them is constructed by means of calibration measurements using several liquid samples, which have different p-values and different filling heights h in the vessel.

Abstract: A device for treating water, particularly a filtration device, including a cartridge, which has a receptacle for receiving treatment agents for water, particularly for receiving filtration agents, and a connecting head disposed on the receptacle, wherein the connecting head at the outer surface thereof has at least one inlet opening and at least one outlet opening. The device further includes a connecting element, which has a holder for the connecting head with at least one inflow opening and an outflow opening, which are connected to the inlet and outlet openings of the connecting head in a sealing manner by means of sealing elements. The connecting head is tapered toward the free end, wherein the outer surface has at least one first curved outer surface section, which is inclined toward the longitudinal axis of the cartridge, and a second outer surface section opposite from the first outer surface section. The inlet and outlet openings are located in the first and/or the second outer surface sections.

Abstract: The invention describes an apparatus for the filtration of liquids and an associated filter cartridge 100, the correct seating of which is ensured and can be established by the user.
