Abstract
The invention relates to a process and apparatus for the capacitive demineralization of liquids containing ions in which, after introducing the liquid into a container, an electric field is applied to capacitor plates (8, 9), which leads to ions of the liquid being conducted through a filter wall (7). The ions conducted through are deposited on the capacitor plates (8, 9) as bilayers (15, 16). By introducing pulsed voltage peaks, microcrystalline structures which result from ionic compounds are precipitated and then removed from the apparatus (1).
Claims13
A process for a capacitive demineralization of liquids containing ions, the method which comprises:
- introducing a liquid into a container;
- conducting ions through a filter wall by applying an electric field to capacitive capacitor elements disposed within the filter wall;
- introducing, with a coil, pulsed voltage peaks into a supersaturated solution forming on the capacitive capacitor elements, for precipitating microcrystalline structures resulting from ionic compounds;
- and
- removing the microcrystalline structures.
An apparatus for a capacitive demineralization of a liquid containing ions, comprising:
- a container formed with an interior space for receiving a liquid containing ions;
- a filter container having a filter/diaphragm wall and defining with a treatment space, said filter container being disposed in the interior space of said container;
- a capacitor element configuration disposed within the filter container;
- and
- a generating device having a coil, said generating device generating voltage peaks to be introduced into the treatment space defined by said filter container.
