Greenhouse Gas Monitoring at Clarification Basins – the Fresenius Off-Gas System
Invisible Climate Killers in Focus: How Wastewater Treatment Plants Must Now Respond
They are indispensable for clean water, but are secretly among the largest sources of direct greenhouse gases: Modern wastewater treatment plants emit massive amounts of highly climate-damaging nitrous oxide and methane. With the new EU Wastewater Directive, comprehensive monitoring of these emissions is now mandatory. The Fresenius Off-Gas System offers operators a turnkey complete solution that determines exact emission rates directly at the basin – without cloud dependency, completely autonomous, and with 100% data sovereignty.
ECS vs. NDUV: The optimal technology for H2S analysis in biogas plants
Hydrogen sulfide is the enemy of every plant—but how can you tackle it most efficiently? Between cost-effective routine and state-of-the-art NDUV precision lies the future of your process optimization. A look behind the membranes and light guides shows: choosing the sensor is more than just a cost issue—it is the safety update for your entire plant.
Gas analysis in the cloud with the Cloud Connect Kit
Gas analysis systems generate valuable measurement data – but they often remain difficult to access.
The Cloud Connect Kit finally makes monitoring easy: real-time data, transparency in operation, and digital connection without IT effort.
Plug in. Connect. Keep track.
Read Now: How We Compensate for Cross-Sensitivities in our Measurement Technology
What if your measurement technology could detect and correct interferences on its own? Our intelligent cross-sensitivity compensation makes exactly that possible. It uses targeted wavelength analysis and mathematical correction methods to precisely separate superimposed signals.
The result: accurate, stable measurement values – even where other systems reach their limits. Discover in the white paper how Fresenius Umwelttechnik elevates gas analysis to a new level with this.
