Real-time optimized aeration

Our solution precisely adjusts aeration cycles:

Intelligent prediction of NH4 load (virtual sensor)
Accurate calculation of aerator operation based on load
Consideration of variable energy tariffs (off-peak/peak)

Objective:
Limit energy consumption without compromising performance.

Consumption reduction

Thanks to the modeling of a virtual NH4 sensor, Purecontrol precisely adjusts aeration times based on load and promotes the activation of aerators during the most advantageous tariff periods.
This significantly reduces energy costs.

Stable effluent quality

Purecontrol applies precise, dynamic aeration control, updated every minute. This technology ensures better stability of effluents, facilitating compliance with environmental standards.

100% advanced monitoring and operator alerts

Aeration control in wastewater treatment plants

By continuously analyzing relevant data (inflow rate, oxygen sensor, redox, recirculation, etc.), our algorithms reconstruct a virtual ammonium sensor and predict its evolution up to +24 hours.
Purecontrol sends control commands to the aerators based on the predicted ammonium load changes (1-minute time steps).

1
En heure de pointe, le taux bas de Nh4 assuré en période 1 permet de ne pas aérer systématiquement tout en restant conforme

2
During peak hours, the low NH4 level ensured in period 1 allows for avoiding continuous aeration while remaining compliant.

3
During off-peak hours, aeration is applied to minimize NH4 levels in anticipation of the upcoming peak hour.
