Hi Natalia,

Biogas operation is always a challenge to one who don’t know critical parameters of operation. If we take very important parameters of operation, then it incorporates VFA, TA, TAN, VFA Profile, Biogas composition.

Out of above parameters, only biogas composition can be online monitored and others need to take samples and measure in lab.

Now, question comes where and when to take samples? So, it is good challenge and learning to monitor critical parameters and decide further operation philosophy.
