Fluence Corporation

- Monitor and Control Wastewater Process



Wastewater characteristics change continuously, depending on rainfall, industrial processes, and even the time of day. Over-aerating is a common, expensive problem that results in excessive energy costs and unnecessary wear and tear on your equipment.

The SmartAerator is a system of controls, sensors, and variable frequency drives that:

  • Constantly samples wastewater oxygen levels and other process parameters
  • Regulates aeration intensity based on wastewater characteristics
  • Eliminates over-aerating
  • Conserves power
  • Provides immediate energy savings

Intelligent Energy Savings

Auto-optimization through artificial intelligence (AI) learning provides maximum energy savings through a precisely tuned adaptive control scheme found only with the SmartAerator. This AI uses historical process information from the plant being monitored, rather than a generic algorithm. Fluence’s extensive knowledge of the hydrodynamic Tornado aerator and system performance lets us optimize the ideal operating range of aeration performance for your specific application, which sets the SmartAerator apart from a conventional control product.

The SmartAerator provides annual energy savings of up to 50% for wastewater treatment facilities. Projects that will realize significant energy savings are those that require high-horsepower aerators, as well as those with multiple aerators.

Monitor Process PerformanceEquipment status anytime, from virtually anywhere.

The SmartAerator comes with a dashboard for tracking and reporting aerator performance. Plant operators can monitor the aeration process remotely. Wastewater analytics can be transmitted easily to SCADA systems and mobile devices.
