DETERMINATION OF MIXING QUALITY IN BIOGAS

2014-3-4  new challenge is to optimize the mixing systems in biogas digesters for less common substrates and higher organic loading rates. The quality of mixing directly aff ects the hydraulic retention time of the fed substrates in the digester, the homogeneity of the mixed suspension, the biogas yield and the total energy consumption of biogas plants. In practice, biogas plants consume about 5–10 % of
