Abstract:
1. A one-drum method to control a cooling water system by determining a rate of consumption of at least one fluorescent polymer in the water of the cooling water system, said method comprising the steps of: (1) calculating the rate of consumption of the fluorescent polymer in the water of the cooling water system at discrete intervals during a learning time period, said calculation comprising the steps of: where SIL is the Scale Index calculated for an interval of time during the learning time period, where TSIL is the Tower Scale Index calculated for an interval of time during learning time period, where FIE refers to the Fouling Index calculated during the evaluation time period, where SIE is the Scale Index for the Evaluation Time Period, where TSIE is Tower Scale Index for the Evaluation Period, (4) Comparing the rate of consumption of the fluorescent polymer during the evaluation time period to the previously determined, in step (2), average rate of consumption of fluorescent polymer during the learning time period for the water in the cooling water system in the following ways: (5) adjusting one or more operating parameters of said cooling water system in order to maintain a desired rate of consumption of the fluorescent polymer, including adjusting the amount of provided water treatment product.
