Test facility for the generation of biogas

The facility was designed and errected in order to operate a biogas plant also on a smaller scale. In the process the disadvantages of the batch process in a laboratory are overcome. Thus a greater proximity to industrial conditions is achieved. Furthermore the automatic feeding as well as the continuous recording of process-relevant measuring data lead to a cost-effictive test operation.

Technical data

  • Volume of the storage tank
  • 150 liters (net)
  • Volume of the fermenter: 400 liters (net)
  • Speed of the  pitched blade impeller with two stirring planes: 40 to 160 rpm
  • Temperature mesophilic / thermophil
    (27 - 60 °C)
     
Digester/Hydrolyses tank

    Foreground: digester with bull’s eye
    Background: Hydrolysis tank

Measurement technology

  • Dual measurement of the pH-value
  • Dual redox measurement
  • Dual measurement of conductivity
  • Dual measurement of the concentration of ammonia
  • Dual measurement of the amount of biogas
  • Dual measurement of the biogas composition (oxygen, methane, carbon dioxide, hydrogen sulphide)
