However, some parameters have to be calibrated according to the substrates characteristics for an adequate prediction of the biogas production and effluent characteristics. This article presents a calibration procedure for the IWA “Anaerobic Digestion Model n°1” applied to the modelling of a digester treating pig slurry. The most sensitive parameters were selected and calibrated combining the results from a continuous digester and from batch trials run with the sludge sampled from the digester and fed with specific substrates additions.
