Biogas production
Inside the methane reactor the active anaerobic sludge is kept in suspension by mechanical mixing. The settled sludge is continuously recycled from the sludge settler to the reactor. More recently, ultrafiltration has been used as an alternative for biomass separation.
Applications
Bio-effluents with low/moderate organic load: COD < 5 kg/m³
Advantages
- All advantages of anaerobic treatment
- Simple
- Stable operation
