Parameter Estimation in Anaerobic Digestion Processes of Fruit and Vegetable Waste
In this work, inverse problem of the anaerobic digestion processes of fruit and vegetable waste and sludge from
biogas plant is considered. The Lavenberg-Marquardt method was applied to solve this problem. A model based on the work
of Grau et al. (1975) was applied to simulate the processes. The laboratory experiment was carried out to obtain an
accumulated concentration of methane which then used to obtain the kinetic parameters from the proposed model. The
model was tested with the experimental data. This work was done with the aim to chose appropriate models to explain the
methane generation process from the fruit and vegetable waste.
