State detection of a wastewater treatment plant
نویسندگان
چکیده
This paper describes a simple rule-based approach for the state detection in a biological waste water treatment plant. The plant shows bi-stable behaviour that makes its control a challenging and difficult task. The good operating point is difficult to reach and easy to lose. The approach combines the mathematical model of the plant and the available measurement information. After the state detection, the control system uses the model developed for the operation point in question and calculates the outlet substrate concentration. The approach is tested by simulations with the Chemostat -model where the kinetics follows Haldane-kinetics.

Adaptive data-derived anomaly detection in the activated sludge process of a large-scale wastewater treatment plant
This work examines real-time anomaly detection and isolation in a full-scale wastewater treatment application. The Viikinmäki plant is the largest municipal wastewater treatment facility in Finland. It is monitored with ample instrumentation, though their potential is not yet fully exploited. One reason that prevents the use of the instrumentation in plant control is the occasional insufficient...
