FLOCCULANT CONTROL STRATEGY
"WITH SMARTDIVER® DATA, DIFFERENTIAL CONTROL USING INTERFACE-MUD SEPARATION PROVIDES A MORE DATA-DRIVEN APPROACH TOWARDS FLOCCULANT DOSAGE."
DEFINITIVE FLOCCULANT DOSING -
USING INTERFACE & MUD LEVEL MEASUREMENTS
The distance between Interface and Mud Level—the Settling Zone—correlates directly with the effectiveness of Flocculants and Coagulants.
In the Settling Zone of a Thickener, solids settle under gravity, concentration increases with depth and settling rates progressively slow. Flocculants enhance particle aggregation in this zone, and the height of the zone indicates dosing efficiency.
Most underperforming Thickeners are overdosed, causing Interface and Mud Levels to merge. Standard response to process upsets—increasing Flocculant—provides short-term stability but creates long-term problems if unchecked.
Sample Trend Profile Data from the SmartDiver®
We can monitor how Flocculation is affecting the Settling Rate.
Contracting Zone (Interface approaching Mud) → Faster Settling → Reduce Flocculant
Expanding Zone (increasing separation) → Slower Settling → Increase Flocculant
Sample Data from a US based Site Trial of the SmartDiver®
In most operating conditions, flocculant dosage and interface level exhibit an inverse relationship.
Increasing Flocculant dosage causes the Interface to drop (faster settling)
Decreasing Flocculant dosage causes the interface to rise (slower settling)
