Polyaluminium Ferric Chloride (PAFC)
PAFC is a composite coagulant combining the advantages of both aluminum and iron salts. It offers the rapid flocculation of aluminum with the dense settling and color removal of iron.
Specifications
| Parameter | Specification |
|---|---|
| Al2O3 Content | ≥ 26% |
| Fe2O3 Content | 2-5% |
| Basicity | 60-85% |
| Water Insoluble | ≤ 1.0% |
Advantages
- Wider pH range than pure aluminum coagulants
- Better color and COD removal
- Faster settling than PAC alone
- Lower dosage cost than using PAC + FeCl3 separately
