Title (EN) SYSTEMS AND METHODS FOR PREVENTING AND REMOVING SCALE IN SANITIZING SYSTEMS
(FR) SYSTÈMES ET PROCÉDÉS POUR LA PRÉVENTION ET L'ÉLIMINATION DU TARTRE DANS DES SYSTÈMES DE DÉSINFECTION
Abstract:
(EN) Methods and systems for preventing scale formation in water sanitizing systems are provided, particularly for pools, industrial water, and potable water treatment. A scale prevention system includes a water line having a pH sensor and an acid injection port. A scale prevention system controller monitors the pH of the water line and acidifies the water to reduce, eliminate, and remove scale from the sanitizing system. The scale prevention controller has both functionality and safety interlocks, and can administer acid to the water line continuously or in bursts.
(FR) L'invention concerne des procédés et des systèmes pour la prévention de la formation de tartre dans des systèmes de désinfection de l'eau, en particulier pour le traitement des piscines, de l'eau industrielle et de l'eau potable. Un système de prévention du tartre comprend une conduite d'eau comportant un capteur de pH et un orifice d'injection d'acide. Un dispositif de commande de système de prévention du tartre surveille le pH de la conduite d'eau et acidifie l'eau pour réduire, éliminer et retirer le tartre du système de désinfection. Le dispositif de commande de prévention du tartre possède à la fois des verrouillages de fonctionnalité et de sécurité, et peut introduire de l'acide dans la conduite d'eau de façon continue ou par intermittence.
