General model for biological nutrient removal activated‐sludge systems: model application

Abstract

The application of a general model for nitrification denitrification biological excess phosphorus removal (NDBEPR) activated‐sludge systems is demonstrated. Results of simulations show the model is capable of predicting sludge production and oxygen use for a range of system types and configurations, and of tracking changes in a number of parameters including soluble phosphorus and nitrate concentrations. Application of the model is demonstrated for aerobic and anoxic–aerobic systems and for a number of nutrient removal systems for both steady‐state and for dynamic conditions.
