The reduction of TRO by temperature (°K) was found to fit a curvilinear relationship in distilled water (r 2 = 0.997) and a linear relationship in seawater (r 2 = 0.996). Based on the decay rate, flow rate, and the length of cooling water flowing through at a given temperature, the TRO level in the cooling water of a power plant could be estimated using the equation developed in this study. This predictive model would provide a benchmark for power plant operators to adjust the addition of chlorine to levels necessary to control bio-fouling of cooling water intake pipelines, but without irritating ambient marine organisms. © 2008 by MDPI. |
