Digester design and build
Digester sizing, construction, feed handling, temperature control and commissioning.
Organic matter is held in a sealed, oxygen free tank where bacteria break it down and release biogas, mostly methane and carbon dioxide. Temperature, retention time and feedstock mix control the yield, and a stable feed matters more than a large one because the bacterial culture takes time to adjust.
What this includes
- Digester sizing against daily feed and retention time
- Tank construction and gas holder
- Feed pre treatment and handling systems
- Temperature control and mixing
- Gas collection and safety systems
- Seeding, commissioning and yield stabilisation
- What you receiveOutput
- Digester built, seeded and producing stable gas
- When you need itTiming
- After feedstock is contracted.
Changing feedstock mix after commissioning. The bacterial culture is slow to adapt and yield can collapse for weeks.
