As part of phase 2, going gas to grid, the amount of gas required to run the whole plant at full capacity needed to be expanded. As part of this process we decided to build another concrete bio digester.
BS2 was designed and built by MT-Energie UK Ltd. The tank was filled up using the digestate liquid from the lagoon and was commissioned in April 2015, working at full capacity in June 2015. The dimensions and gas production of this tank are:
- 8 meters high
- 28 meters diameter
- 4500 m3 of digestate
- 15000 m3 of biogas per day
