Description

The GPBT60 bench allows the study of the methanization of liquid effluents in batches.

Anaerobic digestion is a process of degradation of organic matter in the absence of oxygen.

This degradation takes place thanks to the action of various bacteria and leads to the production of biogas.

The rugged design of this equipment makes it perfectly suited for use in a school setting.

Its anodized aluminum structure on wheels gives it a very high robustness as well as great flexibility of integration into your premises.

The manufacture of this equipment complies with the European Machine Directive.
