<p>A method to control a cooling water system (+) comprising the steps of: a) adding a treatment product (21) to said system (1) comprising inert tracer and tagged treatment polymer in a set proportion; b) providing fluorometers (6, 4); c) using fluorometers (6, 4) measure the fluorescent signal of said inert tracer and the tagged treatment polymer; a) using these signals to determine the amount of said tagged treatment polymer present in said system; b) comparing the amount of said tagged treatment polymer present to the amount of tagged treatment polymer (9) being fed into the system to determine the consumption of said tagged treatment polymer; and c) using said consumption of said tagged treatment polymer to control the concentration cycles of said cooling water system (10, 8).</p> |
