The Comparison of the Production in Developing Biogas System by using Vortex Reactor and Anaerobic Baffle Reactor

Abstract

The purpose of this research aims to generate Biogas system by using vortex model in a pilot plant. For this research, two different digester tanks have been installed to investigate the result of Biogas. The first digester tank (D1) applied the vortex model while the second digester tank (D2) does not apply. The design for both digester tanks also look different from one another, D1 has a circular shape, with two stage, and 250 liters in volume while D2 has a rectangular shape, only one stage, and 250 liters in volume. Fresh chicken manure and inoculums are the main ingredients for this experiment. These 2 ingredients need to be mixed well and weight 250 liters. The ratio are 25:75, 50:50, and 75:25 (Chicken manure : Inoculums). The Hydraulic retention times (HRT) is 10 days starting from the first day of each experiment. As a result, the ratio of 50:50 has shown the optimum outcome to producing biogas from this technique. D1 is able to generated biogas for 6.53 m³  with methane gas of 62.28%, and D2 is able to generated biogas for 22.32 m³ with methane gas of 61.2%.
