Abstract:
A method of controlling a cooling water system in which control is based on information from a control Matrix applicable to the system conditions leading to stress of said cooling water system comprising:(i) providing one or more fluorometers, analytical devices and a controller;(ii) programming said one or more fluorometers, analytical devices and a controller using planning information from a control Matrix for cooling water systems being treated with treatment programs selected from the group consisting of:(a) Stabilized Phosphate;(b) Zinc; and(c) All Organic;(iii) using said one or more fluorometers and analytical devices to determine the status of system conditions leading to stress;(iv) determining the pattern of changes in the status of system conditions leading to stress from step (iii) over time;(v) comparing the changes in the status of system conditions leading to stress in steps (iii) and (iv), with patterns listed in the control Matrix to determine what corrective action(s) is/are recommended; and(vi) using said controller to automatically implement what corrective action(s) is/are recommended.
