Portable Respirometer SN6
Biological diagnosis in the field: the first step towards AI control
The SN6 is a portable respirometer for on-site assessment of biomass condition (autotrophic and heterotrophic bacteria) and discharge control. It is the diagnostic tool to find out a plant’s improvement potential before implementing online control with SN8 + AI. It includes oxygen, temperature, pH and Redox probes.
Tests and Parameters
By means of the SN-6 respirometer, the following tests are performed, which provide the following parameters automatically:
- TEST OUR (Global Respirometry): OUR, SOUR.
- AUR TEST (Nitrification rate): AUR, SAUR.
- TOX TEST (Toxicity): % Inhibition
- DENITRIFICATION TEST: NUR
- COD TEST (COD fractionation) : biodegradable COD and rapidly biodegradable COD
These results are used to estimate the improvement potential before implementing SICAIR or SICTOX: how much aeration is wasted, how much nitrification capacity remains and how the biomass responds to discharges.
Applications
- TOXICITY. Discharge detection.
- Diagnosis prior to AI aeration control (SICAIR).
- NITRIFICATION and DENITRIFICATION optimisation.
- Plants with DILUTION effects.
Why respirometry + AI
The activated sludge process is slow: any decision takes days to show its effect. That is why it is key to detect problems as early as possible and get it right from the start.
Physical or chemical measurements are not enough: you need direct information from the biomass and how the wastewater affects it. That is exactly what the SN6 measures. And our proprietary machine learning models learn from that respirometry to anticipate each plant’s behaviour, instead of reacting once the problem has already arrived.
SN6 advantages
