The basics of convection, mechanical, hydraulic and bubbling mixing used in methane fermentation technologies are discussed. The impact of the intensity of mechanical mixing on the quality and quantity of biogas as well as the course of the fermentation process was evaluated. The influence of the paddle agitator speed rate on quasi-continuous fermentation was investigated. Fermentation was carried out under mesophilic conditions with a hydraulic retention time of 21 days. A 10% increase in biogas production was observed with the increase of the speed of mixing from 60 to 70 min-1 without a significant change in the composition of biogas and other process parameters.
