Abstract
An automated process for controlling the rate chlorine dioxide made from sodium chlorate-chloride and sulfuric acid is generated. The process automatically adjusts the rate of chlorine dioxide production to the needs of the system treated with chlorine dioxide by controlling the feed of one or more of the reactants by means of a multiple feed-back loop system which provides adequate oxidative treatment while avoiding overfeed or underfeed conditions.
