Method of regulating one or more component values in monochloramine production using real-time electrochemical sensing

A system for automatically controlling an active oxidant concentration for a process of producing monochloramine that comprises applying metered amounts of an oxidant solution from a first supply location and an amine solution from a second supply location to a defined area, wherein the system comprises:

• an electrochemical measurement device associated with the oxidant solution at the first supply location prior to the defined area, the device comprising at least a first electrode, a second electrode and an output terminal, wherein the device is configured to generate a feedback signal via the output terminal, wherein the feedback signal is based on an amperometric measurement corresponding to a real-time concentration of active oxidant in the oxidant solution at the first supply location;
• and
• a controller configured to automatically regulate, in real-time and based at least in part on the feedback signal, the metered amount of oxidant solution provided from the first supply location to the defined area, wherein the automatic regulation corresponds to the measured real-time concentration of active oxidant as compared with respect to a target value corresponding to a desired molar ratio of the active oxidant and an active amine associated with the amine solution.
