Anaerobic Digester Data

A dataset containing the data from two separate studies: a pilot study spanning 2019-2020 and a full-scale study spanning 2021-2022. The studies are comprised of 1) data collected daily from an anaerobic digester facility and 2) carbon consumption rate (CCR) data taken every minute by bioelectric sensors and averaged daily. The sensors detect volatile (fatty) acids, thus providing a measurement of biological activity. The pilot study has two digesters and three CCR sensors, while the full-scale study has one digester and two CCR sensors. Diagrams of the two processes are provided. In the pilot study, microorganisms are fed daily, and fats, oils, and grease (FOG) values are higher than in the full-scale study. In the full-scale study, microorganisms are fed continuously, and the facility is more conservative with FOG. Higher amounts of FOG result in more biogas generation; however, too much FOG in the feed can cause system failure. The goal of this study is to evaluate the relationships between biogas and wastes, such as FOG and food waste (FW), in order to find the optimal levels of waste that provide maximum biogas production and prevent system imbalances.
