Abstract
A model for the overall predenitrification process was constructed. The model is based on the kinetic model of IAWPRC but allows for temperature‐ and pH‐dependence of nitrifier growth rate, temperature‐dependence of selected kinetic parameters for heterotrophic bacteria, and a realistic representation of sludge thickening in the secondary clarifier. The latter predicts sludge blanket height and solids concentration profiles in the secondary clarifier under both steady‐state and dynamic conditions. The validity of the model was investigated using data from a pilot‐scale predenitrification plant.Keywords
