In this study, a characterization protocol of sewage sludge in Algeria was carried out. Their objective was to study the process of anaerobic digestion for the production of biogas by analogy to experiments which have already been made in the literature on sludge have the same characteristic as our own product. Five models have been proposed to simulate the anaerobic digestion process; three for the production of biogas and two models for the degradation of organic matter. The performance of the proposed models have been validated with experimental data from the literature. The modeling of the volume of biogas produced was carried out by that of Gompertz and models proposed for different products. We observed a good agreement of the models proposed with the experimental data with a maximum value in r 2 = 0.9996 and minimum in ESM = 6.34 10 -4 . The modeling of the degradation of organic matter was carried out by the first order model (eq IV.19), and dimensionless models proposed. The latter gave a good agreement with the experimental data better than the model of the literature with a maximum value in r 2 = 0.9985 and minimum in ESM = 8.91 10 -4 .
