Aluminum Chlorohydrate (ACH) / Aluminum Chloride Solution
CAS Number: 1327-41-9
Aluminum chlorohydrate solution is a high-basicity aluminum coagulant offering superior performance in drinking water and industrial water treatment applications. Its high charge density accelerates destabilization of colloidal particles at lower dosages than conventional coagulants. It is particularly effective in soft, low-turbidity source waters where standard PAC underperforms.
Technical Specifications
| density | 1.33–1.35 g/cm³ |
| basicity | 83–85% |
| appearance | Colorless to light yellow liquid |
| pH (1% solution) | 4.0–5.0 |
| Al₂O₃ content | 23–24% |
Applications
- Drinking water treatment in soft-water regions
- Low-turbidity source water clarification
- Industrial process water purification
- Swimming pool water treatment
- Textile and dyeing wastewater
Key Features
- High basicity for superior performance in soft waters
- Lower optimal dosage than conventional aluminum sulfate
- Minimal pH depression of treated water
