FIELD: chemistry.
SUBSTANCE: group of inventions relates to biochemistry. A method and an apparatus for producing biogas from organic substances are disclosed. The method includes feeding a substrate into a container with two mixing mechanisms with impellers. A common area is created in the container for mixing the fermentation substrate. The average speed of the fermentation substrate and/or average viscosity of the fermentation substrate in the mixing area are determined. The measurement data are sent to a control unit and controlled quantitative values are varied by the control unit. The apparatus comprises a container, a feeding system, a sensor for monitoring the process and mixing mechanisms, a control unit and mixing mechanisms with impellers. The impellers enable to generate horizontal streams of the contents of the container.
EFFECT: larger amount of the converted fermentation substrate and the generated amount of methane gas.
