Abstract: A filter candle for treating water is provided, which is adapted to be connected to a filter head. The filter candle comprises a housing which is filled with an ion exchange material for softening the water to be treated. The filter candle has a head with one inlet and at least two outlets, and water that can be introduced into the filter head at a first outlet is more softened than water which can be introduced into the filter head at a second outlet.

Abstract: The invention relates to a system for the treatment of drinking water, comprising a softening system with an ion exchanger. This ion exchanger is regenerated using an alkali salt, in particular sodium chloride or potassium chloride. Downstream of the water softening system and upstream of an extraction point, an ion exchanger loaded with hydrogen is arranged followed by a mineralization material which releases calcium, magnesium, and/or silicon.

Abstract: In order to improve the lifespan of the semi-permeable membrane or the yield of the reverse osmosis system in the treatment of drinking water by means of reverse osmosis, the invention provides a device for treating drinking water with at least one reverse osmosis vessel which is divided into at least two chambers by at least one semi-permeable membrane, wherein a first chamber has an inlet for the water to be treated and an outlet for the concentrate, and the second chamber has an outlet for the treated water, wherein the device comprises at least one pressure vessel which is connected to the outlet for the treated water via a line, wherein the device is designed in such a way that, in an idle state, treated water flows out of the pressure vessel, through the semi-permeable membrane and into the first chamber.

Abstract: A backflushing filter having an inlet, an outlet, and a drain; a filter that divides a housing into an inlet chamber that is connected to the inlet and an outlet chamber that is connected to the outlet; a backflushing device having a suction element arranged so that it is able to rotate around the filter on the inlet side of the housing with at least one suction opening that is oriented in the suction direction toward the filter for filter-cleaning purposes; a backflushing duct connected to a suction opening and the drain; and a rotating device which drives the rotational movement of the suction element around the filter when a pressure drop occurs in the backflushing duct; wherein when the pressure drop in the backflushing duct occurs, the rotating device drives the rotational movement of the suction element by the suction direction of the suction opening that is inclined relative to the radial direction of the suction element.

Abstract: The disclosure relates to a water dispenser comprising a preferably cooled carbonator for dispensing carbonated water. The water dispenser comprises a thermoblock, in particular a boiler, for dispensing warm water. The carbonator is connectible to a pressurized CO2 gas container. The water dispenser comprises at least one dosing valve, in particular a switching valve, through which carbon dioxide can be fed into the thermoblock.

Abstract: A germ barrier is provided in the concentrate/wastewater drain from a water installation system towards the wastewater sewer in order to prevent backward contamination with germs, using a UV lamp or a chemical germ barrier that contains an alkaline material, in particular a material selected from the group consisting of carbonates, oxides, and peroxides, and combinations thereof.

Abstract: In order to make available water that is as germ-free as possible, the invention provides a water installation system (1) comprising an extraction point (38) and/or an outlet, wherein the water installation system has a direction of flow (D) towards the extraction point and/or towards the outlet, and comprises at least one chemical germ barrier (200) upstream of the extraction point and/or the outlet when viewed in the direction of flow, wherein the chemical germ barrier is selected in particular from the group consisting of at least one alkalinizing and/or oxidative material, silver, chlorine, and combinations thereof.

Abstract: A water filter comprises an ultrafilter or microfilter, in particular a membrane stack for ultrafiltration or microfiltration, which has a direction of flow (D) and contains an alkalinizing and/or oxidative material that is placed upstream of or within the membrane stack when viewed in the direction of flow.

Abstract: The disclosure relates to a stream regulator for the outlet of a water faucet or of a beverage dispenser, the stream regulator comprising an outer sleeve and a conical insert seated in the sleeve. An annular passage which provides the outlet is located between the insert and the sleeve. An expansion cavity which extends around the insert is located between an inlet and the annular passage.

Abstract: The disclosure relates to a filter head comprising a housing having one inlet and at least one outlet for being connected to an on-site water pipe. A filter candle having a filter candle inlet and at least one filter candle outlet can be installed in the filter head, and the filter head has means for setting a desired degree of softening by setting a blend ratio. The filter head comprises a flow meter and at least one conductivity measuring device, in particular a conductivity measuring cell, and the filter head has an interface for data transmission to an external unit and an integrated computing unit.

Abstract: A filter candle for treating water is provided, which is adapted to be connected to a filter head. The filter candle comprises a housing which is filled with an ion exchange material for softening the water to be treated. The filter candle has a head with one inlet and at least two outlets, and water that can be introduced into the filter head at a first outlet is more softened than water which can be introduced into the filter head at a second outlet.

Abstract: A system for sanitizing a drinking water-carrying device includes a filter candle that can be installed in a filter head. The filter head has one inlet and one outlet, and the system includes a sanitizing cartridge which can replace the filter candle. The sanitizing cartridge includes a sanitizing agent that can be flushed into the drinking water-carrying device via the filter head.

Abstract: A cartridge and a method for enriching drinking water with silicon are provided. A cross-linked silicic acid is used, which can be mixed with a cation exchanger that is preferably loaded with hydrogen and/or with alkalizing agents and/or with activated carbon. Silicon can be released into the water via the silicic acid.

Abstract: A turbine wheel meter for measuring the flow rate of a liquid, in particular water, is disclosed, with a measuring device, with an inlet and an outlet for the liquid to be measured, with a flow channel provided between the inlet and outlet, and with a turbine that has a turbine wheel with curved blades positioned in the flow channel, and wherein the turbine wheel cooperates with the measuring device to measure the flow rate of the liquid. A lower pressure loss and a high measurement sensitivity are achieved by embodying the turbine as a radial turbine with single-curved blades on the turbine wheel.
