6 days ago · The TS concentration in the reactor was 8%. According to the previous study, the dry weight ratio of the alfalfa and cow dung for the CD+AM group was set as 1:2 (8 g alfalfa:16 g cow dung) . The fermenters were purged with N 2 for 1 min to remove the oxygen in the system before the beginning of the experiments. The temperature of the fermenter
Biogas has long been used as a household cooking fuel in many tropical counties, and it has the potential to be a significant energy source beyond household cooking fuel. In this study, we describe the use of low electrical energy input in an anaerobic digestion process using a microbial electrochemical cell (MEC) to promote methane content in biogas at 18, 28, and 37 °C. Although the maximum
Feb 7, 2023 · Biogas production is an environmental-friendly biotechnology that minimizes environmental pollution by making use of wastes streams of various types. A biogas reactor (BGR) otherwise known as anaerobic digester is an industrial/environmental technology that employs anaerobic treatment (fermentation) of these wastes to produce biogas, leaving a slurry (digestate) that can serve as biofertilizer
