Challenges in data collection for load-based real time control with acoustic multifrequency backscattering sensors - experiences from the ENTfrachtEN project 1: Nivus GmbH, Deutschland; 2: Research Institute for Water Management and Climate Future at RWTH Aachen University; 3: Stadtentwässerung Cologne The new European Urban Wastewater Treatment Directive (UWWTD), effective from January 1, 2025, aims to reduce emissions into water bodies. A key challenge is limiting combined sewer system discharges to less than 2% of the annual collected wastewater. Total Suspended Solids (TSS) serve as a crucial parameter to assess pollution levels. The DBU-funded ENTfrachten project in Cologne explores load-based real-time control to reduce emissions. Eight PKM sensors were installed in the sewer system to measure TSS concentrations. However, sensors placed on the sewer bed provided unreliable data due to sediment buildup. In contrast, measurements during heavy rainfall at the CSOs showed good data quality, making them suitable for model validation and emission assessments. The initial project phase revealed that the current measurement concept is insufficient for full control implementation. A second phase is now underway to address data gaps by optimizing sensor placement and developing an improved control strategy to enhance wastewater management. | |
