Description

The biogas plant is used as an R&D facility for process development and process optimization of biogas production.

Fully automatic parallel operation of the two reactors enables direct comparison of process optimizations with a reference operation. By controlling the plant via a process control system with remote maintenance, continuous trial operation over several months can be guaranteed.

Research topics investigated so far have included increasing the efficiency of biogas production by using new substrate mixtures and pre-treatment methods, minimizing substrate losses, partial flow recirculation and nutrient recovery after fermentation residue separation, and developing process control concepts.
