Dynamic modelling of phosphorus in a nutrient-deficient COD removal system
n this paper a new model, tailor-made for nutrient deficient aerobic COD removal, is presented. The Activated Sludge Model No. 1 is chosen as a basis for model development. The original model is extended to include (1) phosphorus state variables; (2) phosphorus and nitrogen limited heterotrophic growth; (3) additional 'luxury' uptake of phosphorus and (4) a separate active biomass component to mod
