A mechanistic mathematical model of the aerated stabilization basin process utilized in the pulp and paper industry is presented. The time variable model is calibrated for a paper mill wastewater treatment system and is used to develop and test a control scheme for the optimization of aeration intensity. The control scheme is shown to reduce aerator usage on an annual basis by seventeen to thirty percent compared to the case of no control. The aerator usage reduction percentage was found to be inversely related to the organic loading rate per aerator horsepower. Savings in aerator usage under the control scheme were equivalent to the existing practice of seasonal aeration control. However, modest improvements in effluent quality variability were observed under the control scheme.
