Valmet's new dry cake measurement improves dewatered sludge quality in wastewater treatment
Valmet Corporation's trade press release on May 3, 2016 at 9:00 a.m. EET
The new Valmet Dry Solids Measurement (Valmet DS) is used to measure dry cake solids for dewatering control in waste water treatment, and it complements Valmet's wastewater control offering. Its safe, low-power microwave technology enables stable and accurate measurements, which can be utilized by the feedback control to optimize polymer dosage and centrifuge. This decreases energy consumption through better torque control.
"The Valmet Dry Solids Measurement helps our customers take their performance forward. Remarkable polymer and energy savings can be achieved through continuous and reliable solids measurement. By maximizing drying efficiency to a target dry cake solids content, additional savings can be achieved through reduced transportation costs and fuel consumption during incineration," says Jarmo Havana, Product Manager, Valmet.
With the help of the improved feedback control enabled by Valmet DS, the TZ Osbourne Wastewater Treatment Plant in Greensboro, North Carolina, USA has achieved a reduction in polymer of up to 25%. The Viinikanlahti wastewater treatment plant in Finland is also providing good results: "Valmet DS is a reliable online measurement. We can now really see how well the centrifuge is operating," says Sami Ilomäki, Operations Engineer at the Tampere Water plant.
Valmet DS is typically located in the downfall section of the dry cake with a screw conveying the sample to the microwave sensor chamber before it is returned to the process. The Industrial Internet functionalities allow full access to the measurement data, alarms and diagnostics that are all remotely accessible.
