Description

What is PAC 30%?

Polyaluminium Chloride (PAC) is an inorganic polymer coagulant with the general chemical formula [Al₂(OH)nCl₆−n]m, where n and m vary depending on the product grade. PAC 30% is a high-concentration grade containing a minimum of 30% Al₂O₃, delivering exceptional coagulation efficiency at lower dosages than conventional coagulants.

PAC 30% is typically available in powder or granular form, ranging in color from white to yellow depending on the purity and application. The powder dissolves rapidly in water, forming a clear, slightly acidic solution.

Key Applications

1. Municipal Drinking Water Treatment

PAC 30% is extensively used in water treatment plants to clarify drinking water, effectively removing turbidity, color, algae, and suspended solids.

2. Industrial Wastewater Treatment

Industries such as textiles, paper, food processing, and petrochemicals use PAC 30% to treat effluents by removing BOD, COD, and heavy metals.

3. Sludge Dewatering

PAC enhances sludge settling and dewatering, reducing sludge volume and disposal costs.

4. Swimming Pools and Cooling Towers

PAC 30% is used to maintain water clarity and hygiene by removing microscopic particles and bio-organic materials.

Benefits of Using PAC 30%

• High coagulation efficiency at lower dosages

• Faster sedimentation and improved water clarity

• Reduces pH adjustment needs compared to alum

• Produces less sludge, lowering disposal costs

• Stable shelf life and easy handling in powder form

Safety and Handling

While PAC 30% is relatively safe to handle, it should be stored in a cool, dry place, away from moisture. Always wear gloves, eye protection, and dust masks when handling the dry product. Avoid direct skin or eye contact, and refer to the product’s Safety Data Sheet (SDS) for complete safety guidance.

Conclusion

Polyaluminium Chloride 30% (PAC 30%) is a powerful and versatile coagulant that delivers superior results in water and wastewater treatment applications. With its high active content, excellent performance, and cost efficiency, PAC 30% is the preferred choice for municipalities and industries seeking reliable water clarification, reduced sludge, and environmental compliance.
