Connect plant data
Combine substrate, gas, pressure, storage, temperature and energy data consistently over time.
Wastewater & biogas plants
Plan gas formation. Coordinate storage and CHP.
Backes combines biological process dynamics, gas storage, pressure control, heat input and energy generation in a continuously reconciled plant model. This turns reactive operation into predictive process control.

Starting point
Biological processes respond with time delay.
Between substrate input and usable gas formation lie reactions distributed over time. Their duration and intensity change with composition, temperature, biological activity and the current operating state.
Classical operating strategies often react only after pressure, storage level or measured gas flow have already changed. As a result, gas production, storage, heat demand and energy use are often coordinated only after the fact.
System view
Digestion, storage, heat and power as one overall system.
The method links biological gas formation, gas network, storage, CHP and heat management. Decisions are therefore not only based on the current measured value, but also on the expected development of the overall system.
Model-based process control
A digital process model, continuously reconciled with the plant.
The digital process model represents the time-dependent gas-formation dynamics and is continuously reconciled with real measurements. Forecast and plant state therefore remain consistently linked.
Represent process dynamics
Account for delays and time-distributed reactions of the biological process in the model.
Forecast gas availability
Predict expected gas availability as well as possible storage and operating states.
Coordinate energy pathway
Derive coordinated setpoints for CHP, pressure control, heat and feed.
Process intelligence
Many signals. One reliable picture of the gas supply.
The analysis connects biological, hydraulic and energy-related variables. This makes relationships, forecast deviations and trade-offs between gas utilization, heat demand and operational safety more transparent.
- Gas-formation rate as a key planning variable
- Evaluate storage and pressure development predictively
- Align CHP operation with heat demand and gas supply
- Avoid flaring events and unfavorable part-load operation where possible
Operational value
More foresight for stable and efficient operation.
The specific value depends on plant configuration, data quality, storage size and operating strategy and is evaluated on a project-specific basis.
01Detect gas surpluses earlier
Expected gas formation becomes visible before pressure or storage level have already started to rise.
02Stabilize CHP operation
Power scheduling can be aligned more closely with expected gas supply and heat demand.
03Reduce flaring operation
Predictive measures can help avoid critical storage and pressure situations.
04Assess deviations faster
Comparing model and measurements makes changing process conditions more traceable.
Patent application filed
Patent application filed: controlling digestion and energy together.
A patent application has been filed with the German Patent and Trade Mark Office for the method for controlling and actuating a digestion plant with gas storage and energy utilization. The approach combines gas-formation forecasting, storage and pressure development, and energy use in a coordinated process control concept.
Safety remains independent.
Mechanical and electrical protective devices, overpressure and underpressure protection and plant-specific safety chains are not replaced by the model-based layer.
