Aluminum Sulphate Forms
Aluminum Sulphate (Aluminum Sulfate), CAS 10043-01-3, is an inorganic coagulant widely used in drinking water, wastewater and industrial water treatment. HOO CHEMTEC supplies Aluminum Sulphate in flakes, powder and granules with stable quality and bulk export capacity.
| Form | Key Characteristics | Typical Applications |
| Flakes | Thin, irregular chips; dissolves at a moderate rate; easy to handle in bulk. | Ideal for large-scale water treatment plants where it is fed via hoppers or conveyors. |
| Powder | Fine, high-surface-area particles; dissolves very rapidly. | Perfect for quick reaction processes, lab use, or applications requiring fast integration into liquid systems. |
| Granules | Small, rounded particles; good flow properties with low dust; dissolves steadily. | Excellent for automated dosing systems, packaging, and situations where dust control and handling ease are priorities. |
What is Aluminum Sulphate Used for
Aluminum Sulphate is mainly used as a coagulant in water treatment. It is also used in several industrial processes, including papermaking and textile processing.
1. Water Treatment
Aluminum Sulphate is widely used as a coagulant for drinking water, wastewater and industrial water treatment. When added to water, it promotes the aggregation of suspended particles into larger flocs, making them easier to remove through sedimentation and filtration.
Typical applications include:
- Drinking water treatment
- Municipal wastewater treatment
- Industrial wastewater treatment
- Process water clarification
- Turbidity removal
2. Paper Manufacturing
Aluminum Sulphate is used in the paper industry as a processing and sizing chemical. It can help improve the interaction between paper fibers, sizing agents and other additives during production.
3. Textile Dyeing
Aluminum Sulphate can be used as a mordant in textile dyeing, helping dyes bind to fibers and improve color fixation.
4. Other Industrial Applications
Depending on grade and formulation, Aluminum Sulphate is also used in selected industrial processes, including leather processing, pigment-related applications and other chemical formulations.

FAQ of Aluminum Sulphate
Aluminium sulphate can be irritating and corrosive. Direct contact with skin, eyes, or inhalation of dust should be avoided. However, when used correctly by professionals in water treatment, it is an effective and approved coagulant. The treated water is safe as the aluminium precipitates and is removed.
It dissolves and hydrolyzes, making the water acidic. This process releases positive charges that neutralize impurities (like dirt and organic matter), causing them to clump together (flocculate) for easy removal. This is the core principle of its use in water purification.
Dosage varies significantly (from 5 to 150 mg/L) depending on raw water quality (turbidity, pH). A jar test is always recommended to determine the optimal, cost-effective dosage for your specific water source.
