In recent years, the interest of real-time control of wastewater treatment facilities has grown. The interest in this area has developed due to changes in legislation on pollutant discharges, technical improvements in sensors and instrumentation, and the need to improve the operation of existing treatment plants. In response to the need for real-time control, the U.S. Environmental Protection Agency has provided funding for research into this area. In order to develop a real-time control strategy for wastewater treatment facilities, a representative model first needs to be formulated. Earlier work has shown that stochastic models, based on deterministic relationships, can be developed to represent processes in a wastewater treatment facility. In particular, ARMA and ARTF stochastic models have proven to be effective. This thesis includes the development of stochastic models for one wastewater treatment facility.
