Influent fractionation and parameter calibration for ADM1: Lab-scale and full-scale experiments
Résumé
This paper presents two methods for the characterisation of input and calibration of an ADM1 model. The first, which is adapted for predictive studies, is named “anaerobic respirometry” and consists of a fractionation obtained by the numerical interpretation of methane production rate curves. These curves are obtained in batch experiments after a pulse of studied substrate in an anaerobic sludge. The second method is developed for full-scale application and complex substrates. The fractionation is initially based on balancing previously measured nitrogen, NH4-N and COD contents in influent, reactor and effluent, and combined with the online gas curve calibration procedure for further fine tuning of input fractionation and detection of kinetic parameters for calibration.
