SmartBNR™ Process Control System

Empowers operators, reduces energy costs, and enhances system reliability
The SmartBNR™​ system features an automated storm water mode, aerated-anoxic TrueSND™ aeration control, automated SRT control, and automated process controls.

The SmartBNR system’s capabilities are unmatched. It offers precise control of simultaneous nitrification – denitrification nutrient removal in a single reactor, predictive aerator response to reactor conditions, integrated control strategy using both oxidation-reduction potential and dissolved oxygen, and automated sludge wasting to maintain optimum sludge age.



  • Automated controls for TrueSND biological treatment (Orbal®, VLR®, and VertiCel® Systems from Evoqua).
  • Stormflow management

 key benefits
