Abstract

L'invention appartient au domaine de désinfection de l'eau des contaminants bactériens par de l'oxygène excité et peut s'utiliser dans la décontamination de l'eau dans différents domaines. Selon l'invention, on décontamine l'eau au moyen d'un photosensibilisant et du rayonnement dans le spectre visible en présence de l'oxygène, le sensibilisant utilisé étant de type cationique dans une solution. On utilise en tant que sensibilisants des colorants cationiques. En tant que sources des formes actives de l'oxygène on utilise l'oxygène moléculaire ou l'oxygène contenu dans l'air. Le procédé proposé dans l'invention assure la désinfection efficace et complète des eaux contaminées par des bactéries.
