Within the process of biological deterioration in the biological tank or the digestion tank, biogas (methane, CO2) will be produced and be stored in gasometers. These gasometers are generally built in steel. Biogenic sulphuric acid is highly aggressive to steel. Additional stress is caused by the elevated temperature.

Typical problems encountered are:

  • Steel corrosion
  • Leakage and risk of pollution due to untight joints
