Abstract:
Avoiding sediment formation in wastewater pressure pipes is often in contrast to the wish of energy efficient pump operation. Characterization of particle behaviour depending transport mechanisms in sewer networks can help to define minimum hydraulic requirements to achieve reduced energy demand for pumping without risking blockages. For this, wastewater specific lab experiments to assess sedimentation and erosion characteristics have been developed. Once constructed, analysis on several wastewater samples can be performed within short periods of time. Different pumping stations with different inflow conditions with respect to location, pre-treatment technology (rake, cutting system, no treatment) and dry as well as wet weather conditions have been investigated regarding settling and erosion behaviour. The received data from the experimental procedures have been processed into sedimentation (settling rates) and erosion (erosion function) data to characterise the sewer conditions inside the sewer system. Thus for each investigated pumping station, specific settling rates and erosion functions have been developed. Ansprechpartner
