EISENMANN technology

Standard biogas EISENMANN equipment consists of the main horizontal digesterthe thermal and disintegration degree and post digester. The facilities are fully automated and equipped with process control systems that measure, control and regulate.

Main horizontal digester
The first level of fermentation is insulated steel tubular reactor with a horizontal shaft mixer and separator layers of sand and sludge.
Solids are supplied to the digester to supply separately, liquids fermentation substrates by a pump. Here substrates digest in a stable temperature between 30 and 55 ° C. During this process is 60-70% of normal yield of gas emited. 

Advantage of a horizontal digester:
- constantly stirring  prevents the sedimentation or slippage of substrates
- sand and gravel, which is collected at the bottom of the digester can be easily exported
- wall heating provides maximum surface area for heat transfer and uniform temperature distribution

Thermal disintegration
After the fermentation in the horizontal digestor the substrate pass through the thermal disintegration, which increases the yield of gas. The substrate is here heated to 70 ° C.
Operation of the biogas is becoming more economical and efficient.

Post digester
After the thermal disintegration is substrate kept in an additional digester (vertical digester with paddle), for further digestion in the second fermentation level.
