PROCÉDÉ DE RÉGLAGE D'UNE OU PLUSIEURS VALEURS DE COMPOSANT DANS LA PRODUCTION DE MONOCHLORAMINE AU MOYEN D'UNE DÉTECTION ÉLECTROCHIMIQUE EN TEMPS RÉEL

摘要

System (100) and method of automatically controlling an active oxidant concentration (e.g. sodium hypochlorite) for a process of producing monochloramine comprising applying metered amounts of an oxidant solution and an amine solution to a defined area (114). An electrochemical measurement device is provided in association with the oxidant solution and prior to the defined area, comprising at least first and second electrodes and an output terminal. A predetermined voltage potential is applied across the first and second electrodes, wherein an obtained amperometric measurement corresponds to a real-time concentration of the active oxidant in the oxidant solution. A feedback signal is generated based on the obtained measurement via the output terminal to a controller (108), which automatically regulates, in real-time and based at least in part on the control signal, the metered amount of oxidant solution provided to the defined area.
