Mise en œuvre de capteurs de turbidité en collecteurs d'assainissement

This paper presents possible objectives for turbidity monitoring in sewerage, and provides details on key issues for getting reliable and accurate turbidity measurements. It relies on the experience gathered during their field work by four French research teams. The topics considered here are the choice of a sensor, calibration procedures, the choice of a measuring site, different in situ implementation modes, sampling strategy, maintenance and uncertainty assessment. A brief description of a few case studies follow up this overview.
