Reliable low solids measurement in the centrate brings significant savings in Steinhäule
The wastewater treatment plant in Steinhäule on the Danube river treats around 40 million m3 of wastewater per year. The roughly one million m3 of sewage sludge produced is dewatered to such an extent that it can be thermally utilized in the plant’s two fluidized bed furnaces. Sludge dewatering has been considerably upgraded with the installation of a highly accurate Valmet Low Solids Measurement (Valmet LS).
Lack of reliable measurements. For example, the formation of gas bubbles proved to be problematic in the optical measurement with a camera.
Valmet LS provided the possibility to control the dewatering process more accurately through the continuous measurement of the solids content in the centrate. Online measurement allows also a direct response.
