title: Monitoring of denitrification performance with combined nitrate and titrimetric measurements.
abstract: A sensor based on on-line measurement of nitrate and acid/base titration is proposed for anoxic activated sludge monitoring. The data probed from the preliminary experiments with denitrifying activated sludge samples using anoxic-titrimetric sensor are information-rich with high data frequency that can be used further in model-based data interpretation and parameter estimation of denitrification process. Moreover, the sensor was able to detect intermediate accumulation, which is an often-observed phenomenon during the denitrification process. It therefore offers the possibility for use in overall performance evaluation of biological nutrient removal plants.
