Abstract
Modeling External Carbon Addition in Combined N-P Activated Sludge Systems with an Extension of the IWA Activated Sludge ModelsThe aim of this study was to expand the IWA Activated Sludge Model No. 2d (ASM2d) to include the effect of adding a readily biodegradable exogenous substrate to anoxic zones of biological N/P removal systems, where it can be used as growth substrate by the Polyphosphate Accumulating Organisms (PAOs) but can not be used by PAOs in the anaerobic zone. The model change was to add a new biodegradable...Author(s)M. SwinarskiJ. MakiniaH.D. StenselK. CzerwionkaJ.
