| Popis: | A surface-based kinetic model for the anaerobic digestion of potato waste was proposed. The model was calibrated and validated, and a local sensitivity analysis was performed to investigate the most sensitive parameters. The model consisted of a modified Anaerobic Digestion Model n.1 where the disintegration process was defined through a surface-based approach able to account for the influence of the particle size on the process development. Ad-hoc experiments were carried out to calibrate and validate the model at a laboratory scale. The calibration and validation procedures accounted for the methane production and organic acid concentrations observed during experimental tests. The quality of model fitting with lab-scale data was evaluated by the Modeling Efficiency, the Index of Agreement, and the Root Mean Square Error methods. Results confirmed the high accuracy of the model for the bio-methane and organic by-products prediction during the anaerobic conversion of potato waste. |
