To improve the fermentation process in the biogas digester, it is necessary to stir evenly on the material substrate, the agitator tool is placed inside the digester to assist the homogenization process of organic material with the aim of increasing the biomethane production process.

Indications of a decrease in the number of biogas products due to sedimentation or separation between liquid waste and solids. For this reason, an attempt was made to conduct a stirring system so that homogeneity occurred and could resemble the initial conditions, so that it was expected to extend the period of biogas production.

Speed of rotation of agitator Agitator Cri-Man TBX 316-0.75/4N stirring by setting the RPM on the motor drive, excessive rotation can damage microorganisms.
