Follow the biology behind wastewater treatment

Wastewater treatment depends on active microbial processes. Respirometry helps laboratories evaluate how sludge, biomass and treatment conditions behave under controlled aerobic or anaerobic conditions.

Gas Endeavour® III is used for wastewater analysis where gas production, gas consumption or oxygen uptake can reveal biological activity, substrate degradation and process performance over time.

Supported Wastewater workflows

Activated sludge activity

Evaluate the activity of aerated sludge through oxygen uptake and respiration based tests, including OUR and SOUR related workflows, and batch denitrification and Anammox activity tests.

Anaerobic respirometry

Study methanogenic activity in anaerobic cultures using SMA assays and biomethane production data.

Wastewater characterisation

Run batch assays such as BMP for anaerobic treatment studies or biochemical oxygen demand (BOD) related workflows for organic matter evaluation.

Process evaluation

Follow the biological and kinetic responses of wastewater treatment processes under controlled laboratory conditions, including the effect of toxic substrates.

Aerobic and anaerobic respirometry

Respirometry is used to study the biological activity of microorganisms by measuring gas production or gas consumption during a controlled test. In wastewater treatment, this can help laboratories understand activity, inhibition, degradation behaviour and process stability.

Aerobic respirometry

Aerobic respirometry is used when oxygen uptake or respiration activity is the main measurement. It is relevant for activated sludge activity, biochemical oxygen demand, organic matter removal, oxygen utilisation and process response studies.

Anaerobic respirometry

Anaerobic respirometry is used when methane production or total gas production is measured under oxygen free conditions. It is relevant for anaerobic sludge activity, BMP assays and studies where methane production reflects the biological conversion process.

Gas Endeavour® III

Gas Endeavour® III is our automated laboratory platform for low gas volume and flow measurement in batch and continuous biological processes. In wastewater treatment applications, it is used for respirometry, sludge activity testing and process evaluation under aerobic or anaerobic conditions.

The system helps laboratories follow gas production and gas consumption over time with less manual work. It supports structured data handling, remote access and automated measurement for wastewater research, method development and industrial process studies.

Common questions about wastewater respirometry

General FAQ

What is respirometry in wastewater treatment?

Respirometry measures gas production or gas consumption from biological activity under controlled conditions. In wastewater treatment, it is used to evaluate microbial activity, organic matter degradation, oxygen uptake and process behaviour.

How is Gas Endeavour® III used in wastewater analysis?

Gas Endeavour® III is used to monitor low gas volume and flow from wastewater and sludge related tests. It can support aerobic and anaerobic respirometry, BOD analysis, sludge activity analysis, BMP assays and process evaluation studies.

What is the difference between aerobic and anaerobic respirometry?

Aerobic respirometry studies biological activity when oxygen is present, often through oxygen uptake. Anaerobic respirometry studies biological activity without oxygen, often through methane or total gas production.

Can Gas Endeavour® III be used for activated sludge activity tests?

Yes. Gas Endeavour® III can be used in workflows where oxygen uptake or respiration activity is monitored to evaluate the metabolic activity of activated sludge.

Can Gas Endeavour® III be used for anaerobic sludge activity?

Yes. Gas Endeavour® III can be used for anaerobic sludge activity studies, including SMA assays and methane production based workflows.

Which wastewater workflows are relevant for Gas Endeavour® III?

Relevant workflows include aerobic and anaerobic respirometry, BMP assays, BOD related workflows, SMA assays, OUR, SOUR, SAA and other biological activity tests.

Which BPC instrument is used for BMP testing?

AMPTS® III is BPC’s main system for automated BMP testing. It is also used for SMA assays, residual gas potential analysis, inhibition studies and anaerobic biodegradability testing.
