The Challenges
- Floc unstable when polymer dosing was reduced
- High polymer dosing required to hold stability
- Risk of floc breakdown at lower dosing
- Belt press operation became unstable
The Solution
One HydroFLOW® i120 unit was fitted to the sludge feed pipe and tested across stepwise dosing reductions on the belt press. The signal improves floc stability, so the dewatering process holds at reduced polymer dosing, with floc breaking down rapidly when the unit is switched off.
