Optimization of Trier wastewater treatment plant process

Client: Stadtwerke Trier, main sewage treatment plant, wastewater treatment plant
Project location: Trier, Germany
Solution applied: Xylem Vue Real-Time Decision Support application

The aim of the project was to support the operator in complying with the monitoring values and to reduce the energy required for the biological treatment stage.

The optimization system made suggestions for the selection of variables that allowed compliance with effluent values while consuming minimal power. The system received all the data in real-time, and the required aeration intensity and chemical levels were optimally controlled depending on the current and expected load of the WWTP.

Optimization of Trier wastewater treatment plant process

The WWTP in Trier, Germany’s oldest city, is designed for a population of 170,000. The utility also manages a second plant, serving about 17,000 residents and about 100 buildings in the municipal region with 500 km (310 miles) of sewer.

The client needed an innovative system to optimize their energy efficiency, increase operational safety and improve chemical use at its main WWTP.

Xylem Vue digital platform solution involved implementing a real-time assistance system for the WWTP. The results showed great success for the Trier WWTP.

Since implementing the Xylem Vue application they have been able to reduce the aeration system’s energy consumption by more than 20%, which corresponds to a savings of 4000 kWh/year.
