Market Overview
Chile is the world’s largest copper producer and a major lithium supplier. Mining operations in Atacama and Antofagasta regions require efficient water management for tailings dewatering, acid mine drainage treatment, and brine processing.
Key Wastewater Challenges
| Parameter | Typical | Discharge Limit |
|---|---|---|
| COD | 500-5,000 mg/L | < 300 mg/L |
| TSS | 200-2,000 mg/L | < 50 mg/L |
| pH | 4-10 | 6-9 |
Recommended Treatment Chemicals
| Chemical | Role | Dosage | Removal |
|---|---|---|---|
| APAM | Flocculant | 20-100 g/t | TSS 95%+ |
| PFS | Coagulant | 30-200 mg/L | Cu removal 90%+ |
| Activated Carbon | Adsorbent | Solvent recovery | COD 60%+ |
