300-litre anaerobic digesters (biomethanizer)
Manufacturer: Dominion & Grimm Environnement
Model: Custom
Features
- Two 300-litre digesters with an effective working volume of 200 L
- Two 300-litre pre-treatment / storage digester feed tanks
- Automated 24-hour, continuous digester feed programming
- Agitation of the four tanks, connected to the automate, using impeller pumps
- Variable feed flow ranging from 5 L/min to 50 L/min
- Fully watertight and made of stainless steel
- Two-inch long inlet and outlet with valves for input and discharge of digestate
- Outlet for gas collection in a Tedlar bag and septum for GC-TCD analysis
- GCTCD biogas analysis (N2, O2, CO2, CH4) and FTIR (H2S)
- Double wall coil heating, ranging from 21 °C to 60 °C
- Possibility to test gas purification membranes at the exits of the two digesters
Examples of applications
- Pre-pilot phase process development on a continuous basis (fed-batch)
- Methane production mechanical parameter optimization (OLR, HRT)
- Methane production physical-chemical parameter optimization (pH, T°C, etc.)
- Long-term toxicity and inhibition tests relating to certain inputs / co-inputs
- Assessment of biogas production using pre-treated inputs (enzymatic/thermal/chemical)
