The Potential of Biogas from Apple Juice

Abstract

This study examines the biogas and energy generation potential from apple juice, optimum factors and inhibitors for the biogas generation process. Instead of apple waste apple juice used for the experiment by assuming apple juice and apple waste compositions are approximately equal. In this report consider about biogas generation amount, flow rate, other factors are affecting the biogas generation, and energy derives from biogas. Moreover, simulated the biogas potential, flow rate, pH & VFA etc.Then compared experimental results with simulated data. Small syringes used as reactors and gas holder. In this experiment considered the effect of the biogas potential with mixing effects and without mixing. According to the yield calculation data, identified 5% is given the maximum yield. According to the 5% sample simulated data, identify the optimum conditions and used simulated results to calculate the energy potential from biogas. pH, VFA, organic load are the main important factors affect to the biogas production. pH should be around 7 for better gas production.The temperature at 35 ± 1.0C was kept for better gas production. UASB is the best reactor for biogas generation because of the smallest volume. Average gas production from apple waste is 35ml/1 ml feed and CH4 production is approximately 60% of the total gas production. Finally calculated the energy potential from methane as 417.7kWh.
