The invention relates to a process and a device for enriching water, in particular drinking water, with magnesium ions. In order to enable enrichment of water with magnesium ions in exchange for calcium ions and/or heavy metal ions during treatment of water, and in particular of drinking water, it is proposed according to the invention to pass the water through an ion exchanger which contains a weakly acidic ion exchange material, wherein at least a part of its ion exchange capacity is loaded with magnesium ions.

Device for enriching water with magnesium ions

A cartridge for treating drinking water, comprising two chambers, wherein one chamber is filled with a highly acidic ion-exchange material and another chamber is filled with a weakly acidic ion-exchange material, wherein one of the ion-exchange materials is loaded with alkali ions or alkaline earth ions.

A device for the electrodeionization of an aqueous electrolyte solution, comprises an electrodeionization module (), an ultrafiltration module () and a connection piece () which connects the electrodeionization module () and the ultrafiltration module () such as to be able to guide a diluate produced from the electrolyte solution during operation of the device in the electrodeionization module () from the electrodeionization module () to the ultrafiltration module (); wherein the connection piece () is devoid of an adjustable pressure-maintaining valve. Via the pressure drop occurring in the ultrafiltration modules (), these devices build up a counter pressure behind the electrodeionization module () which is sufficient to ensure the packing density of the ion exchanger in the electrodeionization module ().

Process and device for enriching water with magnesium ions

A process of producing ultrapure water includes passing a water stream through a plurality of treatment stages in which inorganic and organic species which are present in the water are separated from the water stream; and adding an aqueous hypobromite solution to the water stream in at least one of the stages.

Treatment of water with hypobromite solution

A process for controlled conversion of at least two gases which form ignitable and/or explosive mixtures with one another, in which the gases are absorbed either separately or together in a carrier liquid which is inert in relation to the gases; the carrier liquid with the absorbed gases is fed to a degasser which comprises a closed degassing vessel () which comprises at least one feed line for the gas-laden carrier liquid () and at least one gas outlet () at its upper end, and also one or more drains for the carrier liquid below the feed line for the carrier liquid and in each case connected to a drain pipe (), and in such a manner that the liquid flow rate in the degassing vessel () is less than 0.2 m/s, the gas mixture is removed from the carrier liquid in the degasser and, after leaving the degasser and optional drying, is reacted in a reaction zone; characterized in that the drain pipes () are designed as a closed riser line up to a height level between the exit cross section of the gas outlet from the degassing vessel () and the lowermost level of the reaction zone, and there is pressure equalization between gas outlet () and drain pipes () in this level region. Also described are suitable apparatus for performing the process and specific uses of the apparatus.

Conversion of explosive gas mixtures

A water-conditioning cartridge has a housing that encloses an ion exchanger and can be screwed via a screw thread onto a cartridge-connecting fitting. The cartridge is provided with a water inlet for admission of untreated water, especially from a water-supply system, and with a water outlet, which is connected or can be connected to a consuming component, especially a beverage machine. To ensure that the water-conditioning cartridge can be screwed onto only a particular cartridge-connecting fitting designed for this type of water-conditioning cartridge, the housing and the cartridge-connecting fitting are each provided with a plurality of annular coding ribs, which are disposed concentrically relative to the thread axis of the screw thread, and which engage with one another when the housing is screwed onto the cartridge-connecting fitting.
