Sludge Dewatering Equipment: VOLUTE™ Dewatering Press
Operational issues: complicated sludge, instable sludge quality (pH, SS), use of two types of polymer (coagulant and flocculant)
| Polymer type | Sludge Concentration % | Sludge Volume l/hr | Polymer dosage kg/SS/hr | Dryness % | Dewatered sludge volume kg/hr |
| Coagulant + flocculant | 2,13 | 150 | 3,5 + 0,7 | 15 | 21,3 |
| YESfloc® COEX88 | 0,08 | 19 | 16,8 |
- Replaced two products by one
- Improved storage and operation
- Reduced total polymer dosage by 88%
