Portable anaerobic bioreactor design and production trials

Biogas is a flammable gas mixture that can be produced by anaerobic digestion of organic wastes. It contains 50-65% methane gas, 35-50% carbon dioxide (CO2) and 100-1000 ppm hydrogen sulfide (H2S) in biogas. One the biggest disadvantages biogas production technologies cost purification convert to biomethane. In this study, portable, intermittent bioreactor 20 liter gasometer were designed. The purpose using ensure adsorption H2S CO2 gases raw coming out bioreactor, only power without requiring any external intervention. context, amount content batch with an effective volume 5 liters tested twice. Within scope production, sample was taken every five days from start reactor removal chemical oxygen demand compared initial situation. Each trial lasted 36 days. Then, second stage study started outlet directly connected tank. At stage, waste samples tested. While contents formed as result experiments 558 ± 55 55.4 2.9%, respectively, these values found 45 24.5%, gasometer. As result, it has been determined industrial-scale system adsorbs approximately 88% 55% extra unit. For further studies, changing increasing holding times water are recommended concentrations reduced.
