The Valmet Polymer Concentration Measurement (Valmet PCM) is an optical inline polymer measurement for municipal and industrial wastewater treatment, as well as pulp & paper processes.
Real-time, continuous polymer concentration data creates new opportunities for process optimization, such as more accurate polymer dosage, savings in polymer usage, and faster reaction to process disturbances, among others.
Knowing the actual polymer levels allows facilities to reduce polymer consumption through accurate preparation and dosing. Steady polymer concentration improves flocculation, clarification, dewatering, and other key processes. Better performance saves energy and lowers sludge transport and incineration needs.
In paper & board processes, chemicals are added to improve the retention of fine particles and fillers during web formation. Accurate information about polymer concentration helps optimize wet-end retention and increase process efficiency.
Despite a compact probe design, the optics maximize measurement volume. With more optical channels to collect scattered and reflected light, the probe delivers six times more information compared to conventional solutions improving the performance.
To counter probe contamination common in wastewater applications, Valmet developed an automatic flushing system to keep the Valmet PCM probe clean and measurements stable. The integrated sensor probe flushing unit also includes support for a manual lab sampling valve.
Features:
- Stable polymer quality and optimal polymer concentration
- Improved sustainability through more efficient polymer use and lower energy consumption
- Reduce wastewater sludge transport and incineration
- Better wet-end retention for increased process efficiency
