ABSTRACT:
A method to control a cooling water system based on the rate of consumption of fluorescent polymer is described and claimed. The method includes providing a cooling water system and a water treatment product including at least one fluorescent polymer and a fluorescent tracer. Measuring the fluorescence of the fluorescent polymer and calculating its rate of consumption provides a way of determining whether to adjust one or more operating parameters in the cooling water system.
