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.

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.

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 ().

The invention relates to a method and corresponding plant for the hygienic operation of an ion exchanger, in particular, in water treatment, whereby the ion exchanger is regenerated by a regenerating agent solution during a regeneration phase. According to the invention, a simultaneous disinfection effect may be achieved, whereby chlorine dioxide is generated in situ in the regenerating agent solution and run through the ion exchanger.
