Abstract

La présente invention concerne une technologie présentant deux voies de fourniture d'une source d'acide chloreux à utiliser lors de la désinfection ou du traitement d'hygiène/de purification requis du fait d'un environnement dans lequel un état d'hygiène intérieur ou extérieur s'est détérioré en un état médiocre, ou lorsqu'une fonction de désinfection, de stérilisation ou d'éradication de bactéries est requise durant le processus de stockage d'aliment ou de purification d'eau, élargissant ainsi le champ d'application par l'obtention sélectivement de sources de dioxyde de chlore en fonction des conditions sur site. La présente invention concerne un procédé de fourniture d'une source de dioxyde de chlore afin d'obtenir du dioxyde de chlore (ClO2) en utilisant un sel chlorite comme matériau de départ, le procédé étant appliqué afin d'obtenir une solution aqueuse de dioxyde de chlore (ClO2) par la sélection à partir : d'une application (voie 1) de sorte que le constituant A comprenant des silicates liquides et des sels chlorites et la composition B comprenant des acides organiques/inorganiques sont séparément stockés et, si nécessaire, les constituants A et B sont mélangés afin d'obtenir une solution aqueuse contenant du dioxyde de chlore (ClO2) ; ou l'application (voie 1) de sorte qu'une solution aqueuse de dioxyde de chlore pure (ClO2) ne contenant pas de sels métalliques est obtenue en permettant à un sel chlorite, qui est dilué avec de l'eau, de passer à travers une résine échangeuse de cations.
