Abstract

A method for controlling treatment of an industrial water system is disclosed. The method comprises the steps of providing an apparatus for controlling delivery of at least one treatment chemical, the apparatus comprising at least one sensor and an electronic input/output device carrying out a protocol; measuring a parameter of the industrial water system using the at least one sensor; relaying the measured parameter to the electronic device; adjusting the protocol based on the measured parameter; delivering a concentrated treatment chemical into a stream of the industrial water system according to the adjusted protocol, the concentrated treatment chemical comprising an active ingredient, the active ingredient traced as necessary, the active ingredient having a concentration; repeating the measuring, the adjusting, and the delivering; and optionally repeating the steps for n-number of parameters, n-number of active ingredients, and/or n-number of concentrated treatment chemicals.
