CHALLENGE INCREASING GAS YIELD IN ANAEROBIC DIGESTERS AND BIOGAS PLANTS
Stable bacteria.
Stable gas yield.
We optimize anaerobic processes
Unstable anaerobic processes can have numerous causes.
Due to the high downtime costs associated with sub-optimal operation and insufficient methanogenesis, it is important not to wait too long and hope that the fermenter will heal itself, when typical signs of impending faults occur. If the cause of the problems is not recognized or is difficult to identify, the biological activity may crash.
We understand these specific challenges and develop a customized package of measures for you. Our many years of practical experience in the field of anaerobic process optimization make us a reliable partner for your challenge.
Causes of insufficient biogas yield
- Deficiency symptoms due to insufficient or unavailable micro- and macro-nutrients
- Inhibition of or toxic effect on methanogenic bacteria due to
- Overdosing of trace elements not adapted to the process
- Poor buffering in the system
- Unbalanced C:N:P ratio
- Overfeeding with substances that are too easily degradable
- By-products of the anaerobic process
- Ammonia (NH3)
- Hydrogen sulphide (H2S)
STANDARDS
We focus on individual solutions.
Process optimzation
Practical experience shows that monitoring and analysis of the process are the decisive components for increasing methanogenesis and for optimized process control.
Our optimization concept for anaerobic digestors and biogas plants includes all phases of analysis, individual product selection and coordination as well as process support with ongoing analytical monitoring and documentation.
Rapid assistance with process faults
We offer an expert process and cause analysis and create a customized remediation concept to restore a stable process.
All necessary analyses are carried out in our in-house laboratory by our experts.
ProduCTS AND SYSTEMS
Efficient solutions to optimize methanogenesis:
EXPERTISE: TYPICAL SIGNS OF IMPENDING DISORDERS IN ANAEROBIC REACTORS
Changes in gas:
- Decreasing methane content (CH4) under 50%
- Rising hydrogen content (H2)
- Rising ammonia content (NH3)
- Rising hydrogen sulphide content (H2S)
- Rising carbon dioxide content (CO2) with intermittent occurrence
- Decreasing amount of gas
Changes in the fermenter mash
- Decrease in buffering capacity and consequent drop in pH
- Rising pH with increasing ammonia content
- Rising FOS/TAC value
- Foam formation
- Increased occurrence of floating layers
