Equipment
/// Features:
- Six 7-litre digesters, with an effective working volume of 5 L
- Mechanical blade agitation at a fixed speed of ~ 40 RPM
- Fully watertight and made of stainless steel
- Two-inch long inlet and outlet with valves for input and discharge
- Outlet for gas collection in a Tedlar bag and septum for GC-TCD analysis
- GCTCD biogas analysis (N2, O2, CO2, CH4) and FTIR (H2S)
- Incubation in a temperature controlled or refrigerated bath ranging from 4 °C to 55 °C
/// Examples of applications:
- Maintenance of methanogen inoculum for the purpose of performing methane potential tests (BMP)
- Continuous laboratory-scale process development (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
