The pilot testing research program was designed to evaluate the impact of transmembrane flux, backwash interval and in-line chemical addition on operational efficiency and planning costs for installation of a hollow-fiber microfiltration (MF) membrane system at the Cincinnati Water Works. Pilot testing results were recorded over a range of operational conditions to evaluate the rate of specific flux decline and determine the appropriate range of operating conditions for maximum process efficiency. The following objectives were identified for MF testing: determination of the flux range and backwash intervals that maximize production while minimizing fouling rate, for a range of seasonal temperatures and feed water qualities; evaluation of the estimated run length for different flux and operational conditions; and, evaluation of cleaning efficiency for the ability to restore specific flux to its original value via chemical cleaning. A cost analysis to evaluate the trade-offs of the different operational conditions was developed and is presented here to compare the costs associated with MF treatment under selected operational conditions. This research builds upon earlier work at the Cincinnati Water Works presenting the enhanced virus removal and total organic carbon removal by MF as a result of in-line addition of metal ion coagulant species. Includes 3 references, tables, figures.
