Computer Model for Optimizing the Operation of a Wastewater Treatment System Dealing with Wet Weather Flows

摘要

The feasibility of using the Box-Jenkins Auto-Regressive Integrated Moving Average (ARIMA) Models as a tool to control discharges of untreated overflows of combined sewage (CSO's) was investigated. The models can describe the input/output relationships of a sewage system and the components of this system. Operations data were obtained from Kenosha, Wisconsin to test the ARIMA Models. The data included both dry weather and wet weather operations. The ARIMA Models were examined using an IBM-PC computer. From the preliminary examination, it is highly probable that the ARIMA Models will be of practical use in managing wet weather flows in sewage systems to minimize pollution.
