Product Category: Water Treatment Chemicals / Mining Chemicals
Chemical Name: Aluminium Sulphate
Alternative Name: Alum
CAS Number: 10043-01-3
Chemical Formula: Al₂(SO₄)₃
Appearance: White to off-white powder
Product Overview
Aluminium Sulphate Powder is one of the most widely used inorganic coagulants in water and wastewater treatment.
When introduced into water, it assists with destabilising suspended and colloidal particles and promotes formation of floc, allowing contaminants to be removed more efficiently through clarification, sedimentation and filtration.
The powder format is suitable for chemical preparation and controlled dosing systems.
Typical Water-Treatment Grade Specification
| Property | Typical Specification |
| SKU | MCS-A10 |
| Appearance | White to off-white powder |
| Al₂O₃ Content | Approx. ≥17% |
| Iron – Fe | Typical low-iron grades ≤0.005% |
| Water Insoluble Matter | Typical ≤0.1% |
| pH – 1% Solution | Approx. 3.0–4.0 |
| CAS Number | 10043-01-3 |
| Formula | Al₂(SO₄)₃ |
Commercial water-treatment grades commonly use approximately 17% minimum Al₂O₃ as a reference specification, although manufacturer and application requirements can differ.
