| Abstract |
When granular activated carbon (GAC) contactors are utilized for disinfection byproduct (DBP) precursor control, multiple contactors can be used more efficiently when operated in parallel with staggered GAC replacement cycles, with the effluents of all contactors blended prior to disinfection. By doing so, individual contactors can be operated past a point at which the effluent exceeds a given treatment objective, because the treatment objective must only be maintained in the blended effluent of all contactors. The design of this study incorporated two main goals. The primary objectives were to evaluate the ability of the logistic function to model single contactor breakthrough curve data and to evaluate the success and limitations of predictive models used to determine the integral breakthrough curve, a relationship between single contactor run time and blended contactor water quality. The secondary objective of this study was to evaluate the applicability of these models and predictive methods in the context of the Information Collection Rule (ICR) GAC treatment study data analysis. |
