Co-UDlabs webinar on Acoustic monitoring of suspended solids in natural and engineered systems

Eawag, a partner in the Co-UDlabs INFRAIA project, will hold — on Tuesday, May 16, 2023, from 13:00 -16:30 CEST — a webinar on the principles and applications of acoustic backscattering to monitor suspended solids in natural and engineered systems

Background: Water quality is becoming increasingly important in natural and sewer environments due to sediment-related issues like erosion, transport, and deposition. These problems affect engineered systems, and the environment by causing mechanical obstacles and pollutants attached to sediments. Total suspended solids (TSS) is a crucial parameter to monitor pollutant levels, but few techniques offer real-time data. Traditional methods involve lab measurements or optical backscatter sensors that require significant calibration and maintenance. However, acoustic turbidity monitoring, based on acoustic backscattering, offers a modern approach to TSS monitoring.

Target audience: the webinar is aimed at engineers, planners, and operators of wastewater systems, representatives of municipalities and authorities, as well as manufacturers of monitoring equipment, who would like to gain further insight into modern technologies for environmental monitoring.

Objectives: in this webinar we will discuss the latest developments in TSS monitoring using acoustic backscattering methods, including fundamental principles, particle characteristics, instrument calibration, signal analysis, and inversion methods. Practical experiences from monitoring suspended solids in rivers and wastewater systems will also be shared, as well as limitations of the technique and potential for further development.
