Fermentation test system GärOnA

Fermentation test system GärOnA 型號:Fermentation test system GärOnA
Automated lab fermentation system with online gas analysis
  • Anaerobic lab fermentation test system with integrated gas analysis

    Meaningful fermentation tests are necessary for an efficient biogas manufacturing. With the test results, you can describe the microbiological processes and the degradation characteristics of new substrates. The procedures for fermentation tests are specified, among others, in the VDI guideline 4630.

    Now, the batch and continuous fermentation tests can be carried out fully automatically with the system GärOnA.

    The pressure range in the fermentation vessels can be minimized. This has a positive effect on the solubility equilibrium of methane, carbondioxide and other gas components in the liquid phase.

    While the depressurization a biogas sample from a vessel is fed automatically to the gas chromatograph where it is analysed. It is possible to record the change of the methane formation or the time course of the methane formation rate.

    The fully automated lab fermentation system GärOnA allows very easy and exactly the investigation of anaerobic digestion process, combined with a wide information content.
