Types of Poly Aluminum Chloride
| Feature | White PAC | Yellow PAC |
| Production | Spray drying from high-purity materials. | Mainly spray drying. |
| Key Characteristic | Leaves almost no residue. Prevents secondary pollution to water. | Best balance of performance and cost. Fast dissolution, efficient. |
| Best For | High-standard water: • Drinking water purification • Electronics industry wastewater • Food processing wastewater | General wastewater treatment: • Municipal sewage • Textile dyeing wastewater • Papermaking wastewater |
| Pros & Cons | Pros: Maximum purity, no impurity risk. Cons: Highest cost. | Pros: Good cost-performance, wide applicability. Cons: Not for high-purity standards |
Summary: Choose White PAC for purity-critical uses (e.g., drinking water). Choose Yellow PAC for cost-effective general wastewater treatment.
What is Poly Aluminum Chloride Used for?
- Drinking Water Purification: PAC is widely used as a coagulant in the purification of drinking water to remove impurities and clarify water, making it safe for consumption.
- Industrial Wastewater Treatment: It is effective for treating industrial wastewater from sectors like dyeing, papermaking, and tanning, helping to reduce pollutants and organic matter.
- Removal of Specific Contaminants: PAC is employed to remove specific harmful substances from water, including heavy metals, fluorides, and radioactive pollutants.
- Use in Industrial Processes: Beyond water treatment, PAC serves as a coagulant in the papermaking industry and is used in other applications like cement setting and casting processes.
- Municipal Sewage and Sludge Treatment: It is applied in the treatment of municipal sewage and sludge, aiding in the settlement of solids and improving overall water quality.
FAQ of Poly Aluminum Chloride
Yes, especially the high-purity White PAC grade is produced to meet standards for safe and effective use in drinking water purification processes.
HOO CHEMTEC supply PAC as a dry powder (in both white and yellow grades), which is stable, easy to transport, and can be dissolved to prepare a working solution as needed.
Always add the PAC powder slowly into water while stirring vigorously to prevent clumping. Prepare the solution at the recommended concentration just before use for best results.
PAC offers faster floc formation, better performance over a wider pH range, lower dosage requirements, and produces less sludge compared to traditional alum. It is a more efficient and cost-effective choice for modern water treatment.
Poly aluminium chloride is packaged in 25Kg/Bag, two layers bag, inner is plastic pp bag, outside is wooven bag
Keep it in a cool, dry, and well-ventilated area, in tightly sealed containers to prevent moisture absorption, and away from direct sunlight and incompatible chemicals.
