Compact Plants
Agricultural Biogas Plants
Due to the numerous economic and environmental benefits, many farmers establish a biogas plant
to have another attractive source of income. With many years of experience, we are able to realize
this additional financial pillar together with you and safeguard your farming business' existence for
the next generation.
bue Anlagentechnik GmbH provides you with all the freedom of energy.
Our compact plants are characterized by perfectly matched components that harmonize in an
optimum way with a finely tuned process biology. When designing our on-farm plants, we
consistently follow the provisions of the EEG (Renewable Energy Sources Act). In this way,
we can ensure a reliable technology, excellent operating comfort and efficient performance.
HydroStep Basic
Process:
Typical single-stage process - sequence of all phases of methanation in a fermenter.
Features:
Reduced design
Low investment costs
For uncomplicated substrate compositions
Expandable for fibrous renewable raw materials
Adjustable only to small loading rates
Large volumes due to long residence times
With optional secondary fermentation tank
HydroStep Classic
Process:
Two-stage process - outsourcing of hydrolysis and acidification to external chemical reactors before
methanation (AHS) with the flow method.
Features:
Simple design
High process stability
For all substrate compositions
Foreign substance separation before fermenter
Adjustable to high loading rates
Small volumes due to short residence times
Profitability after short running time
HydroStep Batch
Process:
Two-stage process - outsourcing of hydrolysis and acidification to 2 external chemical reactors
(AHS1 und AHS2) before methanation with the batch process.
Features:
Uncomplicated design
Higher process stability
For all substrate compositions
Foreign substance separation before fermenter
Adjustable to high loading rates
Small volumes due to short residence times
Compensation of costs after short running time
