The quest for cleaner, safer water drives continuous innovation in water treatment chemistry. For decades, Aluminum Sulfate (alum) has been a staple coagulant. However, Polyaluminium Chloride (PAC) has emerged as a more advanced and often superior alternative. NINGBO INNO PHARMCHEM CO.,LTD., a leading manufacturer and supplier of water treatment chemicals, details the comparative advantages of PAC over traditional aluminum sulfate, explaining why many facilities are making the switch.

Both aluminum sulfate and Polyaluminium Chloride function as coagulants, working to destabilize and aggregate impurities in water. However, PAC represents a significant advancement in coagulant technology due to its polymeric structure and higher charge density.

Key Differences and Advantages of PAC

When comparing PAC to aluminum sulfate, several key differences stand out:

  • Efficiency and Dosage: PAC is generally more efficient, meaning a lower dosage is required to achieve comparable or better results in removing turbidity, color, and organic matter. This translates to reduced chemical consumption and lower overall treatment costs for facilities looking to buy PAC.
  • Floc Formation and Settling: PAC forms larger, denser, and faster-settling flocs compared to aluminum sulfate. This improved flocculation enhances the efficiency of sedimentation and filtration processes, leading to quicker treatment cycles and better water clarity.
  • Performance Across Conditions: PAC exhibits better performance over a wider range of pH and temperature conditions, particularly in cold water. Aluminum sulfate's effectiveness can be significantly reduced in low-temperature environments, often requiring pH adjustment.
  • Sludge Production: PAC treatment typically generates less sludge volume than aluminum sulfate. Reduced sludge means lower disposal costs and less maintenance for sedimentation and dewatering equipment.
  • Residual Aluminum Levels: When dosed correctly, PAC generally leaves lower residual aluminum levels in the treated water, which is a critical consideration for drinking water safety and compliance with health standards.
  • Corrosivity and Handling: PAC is often less corrosive than aluminum sulfate, making it easier and safer to handle, store, and transport.
