Numerical study on anaerobic digestion of fruit and vegetable waste: Biogas generation

Abstract

Abstract. The study provides experimental results and numerical results concerning anaerobic digestion of fruit and vegetable waste. Experiments were carried out by using batch floating drum type digester without mixing and temperature setting. The retention time was 30 days. Numerical results based on Monod type model with influence of temperature is introduced. Initial value problems were analyzed numerically, while kinetic parameters were analyzed by using trial error methods. The numerical results for the first five days seems appropriate in comparison with the experimental outcomes. However, numerical results shows that the model is inappropriate for 30 days of fermentation. This leads to the conclusion that Monod type model is not suitable for describe the mixture degradation of fruit and vegetable waste and horse dung.

Numerical Study of Anaerobic Digestion Processes and Biogas Generation from Fruit and Vegetable Waste

“…It is necessary to generate numerical values of the solution at the first three steps. The Runge-Kutta method was applied for that purpose [8] [11]. In particular, there are five parameters.…”
