For procurement managers and R&D professionals in the chemical industry, selecting the right water treatment chemicals is paramount. Polyaluminium Chloride (PAC) stands out as a highly effective inorganic polymer coagulant, widely adopted for its superior performance in purifying water. Understanding the nuances of PAC is crucial for making informed purchasing decisions. As a leading manufacturer and supplier of industrial-grade PAC, we aim to provide clarity on this essential chemical.

What is Polyaluminium Chloride (PAC)?
Polyaluminium Chloride (PAC) is a chemical compound composed of aluminum, chlorine, hydrogen, and oxygen. It functions primarily as a coagulant in water treatment processes. Its effectiveness lies in its ability to neutralize the negative charges of colloidal particles suspended in water, causing them to destabilize and aggregate into larger flocs. These flocs can then be easily removed through sedimentation or filtration.

Why Choose PAC Over Traditional Coagulants?
While aluminum sulfate (alum) has been a long-standing option, PAC offers distinct advantages that make it a preferred choice for many industrial applications. PAC hydrolyzes more readily, leading to faster floc formation and more efficient contaminant removal. Crucially, PAC contains lower levels of aluminum, resulting in significantly reduced aluminum residuals and sludge waste compared to alum. This not only simplifies the treatment process but also lowers disposal costs, offering a more sustainable and economical solution. When you buy PAC from a reputable supplier, you are investing in enhanced efficiency and reduced environmental impact.

Key Considerations When Purchasing PAC
When looking to buy Polyaluminium Chloride, several factors should be considered to ensure you procure the most suitable product for your specific needs:

  • Basicity: The degree of basification indicates the polymer content. A higher basification generally correlates with higher polymer content, leading to a more efficient product for water clarification.
  • Al2O3 Content: Available in various concentrations (e.g., 28%-30%), this parameter dictates the active aluminum oxide content, influencing its coagulant strength.
  • Appearance: PAC is typically available as a yellow or light yellow powder, granules, or liquid. The physical form can influence ease of handling and application.
  • Purity and Grade: Ensure the product meets industrial-grade standards for your intended application, whether it's wastewater treatment, papermaking, or oil refining.

Usage and Storage Best Practices
To maximize the performance of PAC, proper usage and storage are essential. While direct addition to water bodies is possible, preparing a solution first often yields better results. Always conduct a jar test to determine the optimal dosage and pH range for your specific water quality. Maintain appropriate mixing and stirring to ensure full contact between PAC and suspended solids. Store PAC in a cool, dry, well-ventilated place, keeping containers sealed to prevent moisture absorption and agglomeration. By following these guidelines and partnering with a reliable manufacturer, you can ensure consistent and effective water treatment outcomes.
