INTRODUCTION

Simulation tools were used to carry out an optimization study of the Ina Road water pollution control facility (WPCF) in Tucson, AZ, with the goal of improving operations and maximizing treatment capacity. As part of the study, the plant’s high-purity oxygen (HPO) activated sludge system was modeled. The model calibration exercise proved difficult, indicating a problem with either the data or the model. By using the model itself to pinpoint and solve the calibration issues, a previously unconfirmed HPO process problem at the plant was identified and quantified.
