Beschreibung
Zusammenfassung:	The invention relates a method and a device for treating an aqueous solution, in which a pulsed electric field is generated in the aqueous solution between two electrodes. In accordance with the invention, at least one of the electrodes is covered with a layer of a dielectric material which, during operation of the device, completely separates this (these) electrodes(s) from the aqueous solution. This measure in accordance with the invention enables fields strengths to be used which are much higher than those permissible in the known devices. The use of an oxygen-containing gas and a bipolarly pulsed electric field leads to a further improvement of the method in accordance with the invention. L'invention a trait à un procédé et à un dispositif permettant de traiter une solution aqueuse dans laquelle un champ électrique impulsionnel est établi entre les bornes de deux électrodes. Selon cette invention, l'une au moins des électrodes est recouverte d'une couche d'un matériau diélectrique qui, pendant le fonctionnement du dispositif, isole totalement l'électrode ou les électrodes de la solution aqueuse. Cette disposition, prise en conformité avec l'invention, permet d'utiliser des intensités de champ bien plus élevées que ne le permettent les dispositifs connus. L'emploi d'un gaz porteur d'oxygène et d'un champ électrique à impulsions bipolaires se solde par un perfectionnement supplémentaire du procédé selon l'invention.
