Efficient sludge treatment and process control in real time
Reliable measurement of total solids for wastewater treatment plant Bändlegrund with Proline Teqwave MW 500
Due to increasing legal requirements, wastewater treatment plants are continuously required to review their processes and optimize them, if necessary. In this context, operators of the Bändlegrund wastewater treatment plant in Weil am Rhein, Germany saw potential for optimization in sludge management. The installation of the Proline Teqwave MW 500 in-line measuring device from Endress+Hauser made it possible to optimize multiple areas at the same time.
Bändlegrund wastewater treatment plant in Weil am Rhein, Germany, has existed since 1983 and currently has a capacity of 290,000 PE.
Proline Teqwave MW 500 measures the total solids in sewage sludge in real time using microwave transmission.
The result
-
Increased operational safety thanks to process stabilization
-
Reduced energy and polymer consumption due to optimized sludge treatment
-
Process control in real time
-
Minimized manual effort and optimized pump runtime performance
-
Increased digester gas yield
"For us, it was very important that we optimize process control in sludge management in light of the increasing legal requirements in operation. We achieved this thanks to Teqwave MW 500."

The customer requirement
One optimization approach was the removal of primary and secondary sludge from the hoppers of the primary clarifiers. This process was controlled by the runtime of the sludge removal pumps. Adjusting the runtime required the results of a manual sludge level measurement and experienced personnel. Another challenge is the solids-based polymer dosing when dewatering the slurries. The solid content was determined manually and the amount of polymer was added in proportion to volume.
Our solution
Teqwave MW 500 is an in-line measuring device that displays the total solids in sewage sludge in %TS in real time using microwave transmission. Thanks to direct measurement in the inlet to the thickener, the flow of sludge can be balanced and pump runtimes can be automated. During sludge dewatering, real-time solids measurement enables the amount of polymer to be dosed in the inlet of the chamber filter press optimally at all times, even in case of changes to the solids content.
