Abstract
L'invention concerne des procédés en ligne ou hors ligne de nettoyage et de désinfection simultanés d'un système d'approvisionnement en eau industrielle. Le procédé consiste à ajouter à l'eau du système d'approvisionnement un composé sélectionné dans le groupe constitué par des sels alcalins de chlorite et de chlorate et leurs mélanges, et un acide; puis à laisser l'eau du système d'approvisionnement circuler pendant plusieurs heures. La réaction des sels alcalins de chlorite et de chlorate et de l'acide produit un dioxyde de chlore, in situ, dans l'eau du système d'approvisionnement. Le dioxyde de chlore tue les micro-organismes et l'acide agit pour éliminer les dépôts présents sur les surfaces de l'installation en contact avec l'eau. Un procédé de substitution consiste à utiliser un agent de chélation et un biocide. D'autres réactifs de nettoyage et de désinfection éventuels pouvant être ajoutés, si besoin est, comprennent des inhibiteurs de corrosion, des agents de chélation, des biocides, des tensioactifs et des réducteurs. Les procédés de nettoyage et de désinfection de l'invention fonctionnent dans divers systèmes d'approvisionnement en eau industrielle, dont des systèmes d'alimentation en eau de refroidissement ou en eau de chaudière.
