Design and Manufacture of a Biogas Measuring Device Produced by the Anaerobic Digestion of Organic Waste

Manufacture of Biogas Measuring Device

Abstract

The production of biogas through anaerobic digestion of organic waste has been recognized  as a promising source of renewable energy. Accurate measurement of biogas production is crucial for studying the effect of different parameters affecting the production of biogas. In depth theoretical study was carried out to design and manufacture a biogas measuring device that can measure a very small volume of gas (2-20 mL) at very low pressures (close to atmospheric pressure) with high accuracy (18.95± 0.16 mL) that met the laboratory work requirements. The device utilizes the principle of liquid displacement and buoyancy to measure the volume of biogas produced during anaerobic digestion. The device was calibrated using a known volume of gas and then tested it. The results showed that the device was able to accurately measure the biogas production rate. The device is easy to use, affordable and can be scaled up for use in larger anaerobic digestion systems. The successful design and manufacture of  this biogas measuring device will contribute to the efficient and effective operation of anaerobic digestion systems and the utilization of renewable biogas as a source of  energy.
