Reliable solids measurements for centrifuge control
Vaasa Water’s Pått wastewater treatment plant wanted their new centrifuge to operate fully automatically, which requires several continuous measurements. With a Valmet TS and Valmet DS the plant can control the polymer dosing and measure the dry content. The whole project paid for itself in about 1.5 years through the considerable savings in the reprocessing costs of the dried sludge.
