Our biogas and organic fertilizer analytic
For continuous gas production, regular control of input materials (renewable raw materials, animal excrements, etc.) is essential. Even fluctuations in dry matter of 2 - 3 percent have a considerable effect on the digester load. The comparison of the expected gas yield, which is shown in our certificates, with the actual gas production enables you to make a realistic yield assessment.
During ongoing biogas process, changes should only be made slowly. In addition to gas yield and temperature control, regular examination of the fermentation substrate for the most important process parameters is strongly advised (pH, nitrogen, FOS, TAC, redox potential). This is the only way to detect process disturbances at an early stage.
You will find a large part of our analyses in the above headings and boxes. If you still cannot find the analysis you are looking for, please call us - we will be happy to advise you.
