Sewage treatment plant

Gas detection systems for wastewater treatment plants –
Safety in every phase of wastewater treatment

Wastewater treatment plants play a central role in environmental protection.

They clean our wastewater and ensure that harmful substances are not released into the environment. However, the process of mechanical, biological and chemical purification produces hazardous gases – often odorless, toxic or even explosive.

Typical hazardous substances in wastewater treatment plants:

  • Methane (CH₄): Formed during anaerobic digestion. Highly explosive.
  • Hydrogen sulphide (H₂S): Toxic even at low concentrations, with a characteristic “rotten egg” smell – odorless and life-threatening at high concentrations.
  • Carbon dioxide (CO₂): In closed rooms, it displaces oxygen – risk of suffocation.
  • Ammonia (NH₃): Irritant, toxic, produced, among other things, during the decomposition of nitrogenous compounds.
Why are gas detection systems indispensable?

  • Sewage treatment plants are often large, with accessible shafts, pumping stations and closed tanks – ideal places for gas accumulations. Without early detection, these gases can:
  • Endangering the health and lives of employees
  • Trigger explosions or fires
  • Damage system parts or cause downtimes
Our solution: Reliable gas detection technology for continuous use

As a specialist in gas detection systems, we offer robust, easy-to-maintain measuring and alarm systems that are precisely tailored to the requirements of wastewater treatment plants – stationary or mobile.

Our gas warning systems reliably detect dangerous concentrations – before it becomes critical.

We advise, plan, install and maintain – so that your system runs safely and your team is protected.
