CLEARFLOW™ TECHNOLOGY OVERVIEW
Reduction of turbidity in the liquor from green, white and mud washing clarifiers improves the operation
of the Recaust Plant. Many pulp mills have increased the loading on their clarifiers in order to meet greater
demands for liquor in the digesters. In addition, hydrodynamic modeling shows that older technology for
feedwell and bustle pipe design is inadequate to sustain flows above critical levels where product clarity
decreases dramatically. As a result, low turbidity may not be achieved even when injecting polymer.
