Desulfurization
Keep sulfur levels reliably under control with our highly effective iron hydroxide
Why H₂S Is One of the Biggest Problems
in Biogas Plants
High sulfur levels are among the most common causes of engine malfunctions, high maintenance costs, and biological instability. H₂S is produced in almost every substrate—the key is how well you can control it. Without targeted desulfurization, you risk corrosion, process fluctuations, and unnecessary costs.
The Impact on Plant Operations
- Corrosion on Pipes and Equipment
- Malfunctions and damage to the CHP unit
- Turmoil in the biology lab
- Rising operating costs
- Lower efficiency
Even small amounts of H₂S are enough to cause damage—which is why consistent desulfurization is essential.
SulFEX or activated carbon—
which is the right solution for you?
Both solutions have their strengths—and often, combining them is the most efficient approach. We’ll help you choose the right strategy based on:
- Substrates
- System load
- Biological stability
- Previous sulfur levels
- Technology & engine manufacturer
