Reliable foam control with precise dosing technology
Foam formation in the digestion tower can cause considerable disruption - from foam in gas pipes and blockages to increased cleaning effort and rising defoamer consumption. Digester gas production is also impaired, and in extreme cases there is a risk of overflow.
This is usually caused by surface-active substances such as fats and surfactants as well as filament-forming microorganisms. The resulting foam is transported upwards by gas buoyancy and enters gas pipes and fittings. There it leads to contamination, malfunctions and impairs the safe discharge of gas.
Challenges in foam control
- Foam in gas pipes and fittings leads to malfunctions.
- An uneven defoamer dosage reduces the effectiveness and causes the foam level to rise further.
- In extreme cases, the operational safety of the system is jeopardised.
The solution from sera
- Targeted dosing: sera dosing systems enable precise and needs-based addition of defoaming agents - for effective reduction and prevention of foam formation in the digestion tower.
- Modular design: Freely configurable assemblies and diaphragm pumps allow flexible adaptation to process requirements and media.
- Versatile use: The defoamer can be removed from small containers, IBCs or storage tanks - ideal for different sizes of operation.
- Compact design: Wall mounting or optional floor stand save space and facilitate integration into existing systems.
- High level of safety: Mounting panel with drip tray, splash guard and optional leakage probe ensures reliable operation and optimum personal protection.
- Simple commissioning: The proven plug & socket system minimises installation time and maintenance work.
The precise dosing technology from sera ensures stable, reliable foam control, minimises faults and thus guarantees safe, efficient and low-maintenance system operation - reliable, practical and sustainable.
