Biobed® DUO

The Biobed® DUO design, Biothane's advanced two layer reactor system,has been developed to provide advantages for specific applications.

System features

Standard reactor heights of 25 m combined with a standard range of reactor diameters provide a range of reactor volumes up to 4000 m3.

Both reactor and conditioning tank are completely enclosed and pressurized to eliminate any emission or smell from the system

Mixing conditions in the sludge bed can be set by the operator independent of other system parameters
The sludge withdrawal piping grid is multipurpose designed for Nitrogen injection at the reactor floor to temporary boost mixing of the entire sludge bed.

The sludge withdrawal piping grid can be cleaned and flushed in – situ with the reactor feed pump to prevent blockage.
 

Anaerobic treatment advantages

  • COD loading rate 20-30 kg COD/m3.d
  • COD removal efficiencies 75-90%
  • Compact system using minimal space
  • Full control of emissions, no odour
  • Biogas production for energy recovery
  • Minimal surplus sludge production
  • Fully automated and operator friendly with the reactor feed pump to prevent blockage
