Metso Develops Density Transmitter for Total Solids MeasurementJuly 20, 2006
Microwave-based device measures biosolids for wastewater treatment process.
NORCROSS, GA, /BUSINESS WIRE/ -- kajaaniTS from Metso Automation, developed from third-generation microwave density transmitters, combines cost efficiency with the extreme accuracy associated with microwave technology to measure wastewater biosolids (sludge).
Microwave technology has been used to measure density in process industries for well over a decade. By using microwave technology, the kajaaniTS transmitter meets the needs of wastewater treatment plants, with no compromises in accuracy. The kajaaniTS can be used on low to high solids measurement, including primary sludge, dewatering, and dewatered cake applications.
One wastewater reclamation facility in Michigan, treating 28 million gallons per day, half from industrial users, is using the kajaaniTS transmitter in an "activated sludge" wastewater process. The facility has six primary settling tanks and seven secondary clarifiers, as well as four belt-filter presses for handling solids. Since adding the kajaaniTS transmitter to their primary sludge application, they have benefited from pumping optimization.
Benefits of total solids measurement:
- Lower polymer consumption
- Fewer laboratory analysis
- Reduced handling charges by controlling solid content
- More efficient use of digesting
- Pumping optimization in primary sludge
When applied to the wastewater treatment process, microwave technology offers significant advantages over other types of total solids measurements.
- Single-point calibration
- Maintenance-free operation
- Ceramic sensors that resist product buildup
The interface between the kajaaniTS transmitter and the plant control systems are ensured. kajaaniTS is available with mA+HART, Profibus PA, or Foundation Fieldbus connectivity. DTM descriptions provide connectivity with FDT-based configuration and operation monitoring systems.
