Höchste Präzision – Verlässliche Daten

Der Airyx WGA020 Abwasser-Gas-Analysator ermöglicht eine hochpräzise Echtzeit‑Überwachung von N₂O, CH₄, CO₂ und O₂ in belüfteten Becken und berechnet automatisch Netto‑Emissionsraten für Prozess‑ und Klimaberichte.

Das System wurde für das langfristige Treibhausgas‑Monitoring in Kläranlagen entwickelt und entnimmt die Proben direkt oberhalb der Wasseroberfläche mittels schwimmender Haube. Der Analysator misst kontinuierlich N₂O, CH₄, CO₂ und O₂ und ermittelt die Netto‑Gasflüsse über einen integrierten Volumenstromsensor.

Eine Probenlufttrocknung, automatische Querempfindlichkeits‑Korrekturen sowie ein temperaturstabilisiertes Sensorgehäuse gewährleisten einen stabilen, driftarmen Betrieb auch bei wechselnden Umweltbedingungen.

Praxisgerechtes Design für Kläranlagen

Das robuste IP64‑Gehäuse ist für den dauerhaften Außeneinsatz ausgelegt. Es sind keine fest angeschlossenen Kalibriergasflaschen erforderlich – das reduziert Betriebsaufwand und Kosten.

Bedienung und Datenzugriff erfolgen über das Front‑Touchdisplay oder eine browserbasierte Weboberfläche via LAN. Optional ermöglicht eine LTE‑Anbindung den sicheren Fernzugriff für Monitoring und Service.

Häufig gestellte Fragen

Welche Gase misst der WGA020?

Der Abwasser-Gas-Analysator Airyx WGA020 ermöglicht gleichzeitige Messungen von N₂O, CH₄, CO₂ und O₂ für ein vollständiges Emissionsprofil von Abwasseranlagen.

Welches Messprinzip wird verwendet?

Der Analysator nutzt das NDIR‑Messprinzip für N₂O, CO₂ und CH₄, während O₂ über einen elektrochemischen Sensor erfasst wird.

Benötigt der Analysator Kalibriergasflaschen?

Es ist kein kontinuierliches Kalibriergas erforderlich; lediglich eine jährliche Sensorkalibrierung mit Standardgas ist notwendig.

Wird das System durch wechselnde Umgebungstemperaturen beeinflusst?

Der WGA020 arbeitet zuverlässig im Temperaturbereich von −10 °C bis +40 °C dank temperaturstabilisierter interner Komponenten.

Wie häufig ist eine Wartung erforderlich?

Die jährliche Wartung umfasst die Sensorkalibrierung, den Austausch des Scrubbers sowie die Reinigung der Probenahmehaube.

Kann das System mehr als eine Haube überwachen?

Ja, der Dual‑Hauben‑Betrieb ermöglicht die Überprüfung räumlicher Variabilität sowie quasi‑gleichzeitige Messungen.

Wie werden die Emissionen erfasst?

Eine schwimmende Probenahmehaube sammelt das Gas direkt oberhalb der Wasseroberfläche für eine stabile und repräsentative Probenahme.

Wie erfolgt der Datenzugriff?

Über das Touch‑Display, das Web‑Interface, Ethernet oder optional über ein LTE‑Modem für den VPN‑Fernzugriff.

Was die Beispieldaten zeigen

Beispieldaten veranschaulichen typische tägliche Muster von Treibhausgasemissionen in Belebungsbecken. CO₂ und N₂O zeigen ausgeprägte tageszeitliche Spitzen, die durch biologische Aktivität, Belüftungsintensität und Beckenbelastung bestimmt werden. Aufgrund des sehr hohen Treibhauspotenzials von N₂O führen bereits geringe Konzentrationsänderungen zu einer starken Klimawirkung. Der WGA020 löst diese Dynamiken in Echtzeit auf und unterstützt Betreiber dabei, Emissions‑Hotspots zu identifizieren, die Belüftung zu optimieren und Netto‑Emissionsflüsse für Berichterstattung und Prozesssteuerung zu quantifizieren.

Fazit

Zusammenfassend bietet der WGA020 zuverlässige Echtzeit‑Messungen von Treibhausgasen für moderne Abwasseranlagen. Die Kombination aus der Überwachung von N₂O, CH₄, CO₂ und O₂, dem robusten Außendesign sowie automatisierten Korrekturroutinen macht ihn zu einer verlässlichen Langzeitlösung für die operative Prozessoptimierung, die regulatorische Berichterstattung und wissenschaftliche Anwendungen.

Airyx WGA020 Wastewater Gas Analyser

High‑precision N₂O, CH₄ and CO₂ emission monitoring and O₂ control with the Airyx WGA020 wastewater gas analyser

Zur deutschen Produktseite wechseln

High precision – Reliable data

The Airyx WGA020 wastewater gas analyser provides high‑precision, real‑time monitoring of N₂O, CH₄, CO₂ and O₂ in aerated basins and automatically calculates net emission rates for process and climate reporting.

Designed for long‑term greenhouse‑gas monitoring in wastewater treatment plants, the system samples directly above the water surface using a floating hood. In addition, the analyser measures N₂O, CH₄, CO₂ and O₂ in real time and derives net fluxes through an integrated total‑flow sensor.

Moreover, sample‑air drying, automatic cross‑interference correction and a temperature‑stabilised sensor housing ensure stable, low‑drift performance under changing environmental conditions.

Field‑Ready Design for Wastewater Environments

Additionally, the rugged IP64 enclosure supports continuous outdoor operation. The system requires no permanently attached calibration gas bottles, which reduces operating effort and cost.

Instrument control and data access are available via the front‑panel touch display or browser‑based web interface over LAN. Furthermore, optional LTE connectivity enables secure remote access for monitoring and troubleshooting.

Frequently Asked Questions

Which gases does the WGA020 measure?

The Airyx WGA020 wastewater gas analyser provides simultaneous N₂O, CH₄, CO₂ and O₂ measurements for complete wastewater emission profiling

Which measurement principle is used?

The analyser uses NDIR to measure N₂O, CO₂ and CH₄, while O₂ is captured via an electrochemical sensor.

Does the analyser require calibration gas bottles?

No continuous calibration gas is needed; only annual sensor calibration with standard gas is required.

Is the system affected by variable ambient temperature?

The WGA020 operates reliably between −10°C and +40°C due to temperature‑stabilized internal components.

How often does maintenance occur?

Annual maintenance covers sensor calibration, scrubber replacement and cleaning of the sampling hood.

Can the system monitor more than one hood?

Yes; dual‑hood operation allows spatial variability checks and quasi‑simultaneous measurements.

How are emissions captured?

A floating sampling hood collects gas directly above the water surface for stable, representative sampling.

How is the data accessed?

Via the touch display, web interface, Ethernet or optional LTE modem for remote VPN access.

What the example data shows

Exemplary data illustrates typical daily patterns of greenhouse gas emissions in aerated wastewater basins. CO₂ and N₂O exhibit clear diurnal peaks driven by biological activity, aeration intensity and basin loading. Because N₂O has a very high global warming potential, even small concentration changes translate into strong climate impact. The WGA020 resolves these dynamics in real time, helping operators identify emission hotspots, optimize aeration and quantify net emission fluxes for reporting and process control.

Conclusion

In summary, the WGA020 provides reliable real‑time greenhouse‑gas measurements for modern wastewater facilities. Its combination of N₂O, CH₄, CO₂ and O₂ monitoring, robust outdoor design and automated correction routines makes it a reliable long-term solution for operational optimisation, regulatory reporting and research applications.
