Available Product Types
Procurement managers face different dosing equipment constraints. We provide three distinct physical forms to match your specific silo feeding and dissolution tank setups.
Aluminum Sulphate Flake
For municipal water plants with standard dissolution tanks requiring steady, predictable melting rates without bridging in hoppers.
- Optimal bulk density for standard transport
- Consistent dissolution curve
- Standard 16-17% Al₂O₃ specification
Aluminium Sulphate Granules
Facilities utilizing automated screw feeders require materials that flow freely. Granules prevent caking and reduce dust during manual or automated loading.
- Low dust generation for safer handling
- Excellent flowability for auto-dosing
- Stable storage characteristics in humid climates
Aluminum Sulphate Powder
Industrial processes requiring immediate chemical reaction and rapid dispersion, such as specialized paper sizing or specific chemical compounding.
- Maximum surface area for rapid reaction
- Non-iron grade available for color-sensitive uses
- Suitable for dry blending formulations
Common Water Treatment Challenges
Plant operators frequently encounter raw water fluctuations that disrupt clarification efficiency. Our Aluminum Sulphate provides a stable coagulation response to these variables.
High Turbidity Spikes
During heavy rainfall, raw water turbidity exceeds clarifier design limits, causing poor clarification efficiency and filter blinding.
Excessive Chemical Cost
Low-concentration coagulants require massive dosing volumes, increasing logistics costs and sludge disposal expenses.
Unstable Water Quality
Inconsistent raw material from suppliers leads to fluctuating pH levels and difficulty meeting strict effluent discharge parameters.
Slow Flocculation
Poorly formed, lightweight flocs settle too slowly, reducing the overall hydraulic capacity of the treatment plant.
What is Aluminum Sulphate？
Aluminum sulphate is an inorganic chemical compound commonly used as a coagulant in water treatment and as an industrial raw material. It appears as a white crystalline solid or powder and is highly soluble in water.
-
✓Effectively removes impurities and suspended particles in water treatment processes.

Frequently Asked Questions
Technical insights for procurement and plant engineering teams.
What Is Aluminum Sulphate (CAS 10043-01-3)?
What Is Aluminum Sulphate Used For?
1. Water Treatment: Coagulates suspended impurities into larger flocs for easier filtration.
2. Wastewater Treatment: Removes phosphorus and clarifies industrial effluent.
3. Paper Industry: Precipitates rosin size onto paper fibers, improving water resistance.
4. Agriculture: Lowers the pH of alkaline soils, creating better growing conditions for acid-loving crops.
Aluminum Sulphate vs Poly Aluminium Chloride (PAC)?
How To Choose The Right Grade of Aluminum Sulphate?
- Al₂O₃ Content: Standard industrial grade is 16-17%. Higher content means lower dosing volume.
- Iron Content: For drinking water or high-grade paper, choose "Non-Iron" grade (Fe ≤ 0.005%) to prevent yellowing. For wastewater, standard grade (Fe ≤ 0.5%) is sufficient and more economical.
- Form Type: Choose Flake for standard tanks, Granules for automated feeders (low dust), and Powder for rapid dry blending.
