Abstract :
Three methods are presented for estimating the biological oxygen demand (BOD) given measurements of dissolved oxygen (DO). The purpose of this paper is to provide a useful scheme for predicting BOD levels in aquatic ecosystems given time series input of DO. The Streeter-Phelps equations, which describe the basic relationship between DO and BOD in aquatic systems, are used as steady-state and transient estimators. Application of these methods to the control of an oil refinery waste treatment facility is discussed.
