A pilot-scale trickling filter has been constructed in order to collect experimental data on a fully characterized biofilm system for the selection, development, calibration and corroboration of mathematical models which describe such a system's dynamic behavior. The design of the unit was made such that it allows a full characterization of the relevant(More)
The " simulation benchmark " proposed by Spanjers et al. (1997) is a standardised procedure for the objective evaluation of control strategies for the activated sludge process. This paper describes the application of the benchmark on two biomass loading control strategies proposed in literature. During implementation, several assumptions about the original(More)
Oxygen transferred from the liquid phase into a biofilm can be used for aerobic degradation of organic matter and for nitrification. A second possible pathway for the removal of organic matter is denitrification in anoxic zones deeper in the biofilm. At high organic loading rates with insufficient oxygen supply to the biofilm, denitrification could be(More)
The process characteristics of a pilot-scale trickling filter system were quantified by means of a measurement campaign with the use of off-gas analysis. A load shift experiment was conducted in which the influent load to the trickling filter system was suddenly decreased. To model the biodegradation in the filters, the model developed by Rauch et al.(More)
In this paper, the practical implementation and validation of advanced control strategies, designed using model based techniques, at an industrial wastewater treatment plant is demonstrated. The plant under study is treating the wastewater of a large pharmaceutical production facility. The process characteristics of the wastewater treatment were quantified(More)
