Solutions for corrosion issuesCompact, effective and environmentally friendly.

Hydrogen sulfide is the result of oxygen-depleted degradation processes and is the main component of the unpleasant odour. It also attacks the fabric of the sewer and, over time, can destroy it. This is due the microbially induced corrosion (MIC) caused by hydrogen sulfide which attacks concrete and steel. Ventilating the sewer system can really put the brakes on this process while simultaneously reducing odour emissions.
