Foaming Wastewater Liquid Level Sensor


foaming-wastewater-level-measurementWhen a Colorado municipality needed reliable level measurement of their foaming aeration tanks, they turned to Flowline. Foam occurs in activated sludge processes and is a common operational problem for plant operators. It consumes reactor volume, decreases treatment efficiency and sticks to everything it contacts. Additionally the density, thickness and surface characteristics of foam are dynamic, and further complicating to reliable level measurement. For this reason, Flowline suggested the use of our pulse radar liquid level sensor that’s unaffected by foam and it’s variables. The pulse radar sensor is flange mounted above the aeration tank and provides continuous level data to the SCADA, which in turn, controls the treatment process. The sensor is unaffected by foam. Flowline is reliable level measurement.
