Combining batch and continuous experiments for ADM1 model calibration: application to anaerobic digestion of piggery wastewaters

Abstract : Modelling of anaerobic digestion processes is a key aspect to study and optimize the digesters and related waste streams. However, some parameters have to be calibrated according to the substrates characteristics for an adequate representation of the biogas production and effluent characteristics. This article presents a calibration procedure for the IWA Anaerobic Digestion Model n°1. After a selection of the most sensitive parameters, a calibration of the selected parameters was performed using simultaneously the results issued from a digester working continuously and results from batch trials made with the sludge issued from the digester and specific substrates additions. This method was successfully applied for the modelling of a digester fed with piggery wastewater.
