For procurement managers and R&D scientists in the chemical and water treatment sectors, selecting the appropriate Polyaluminium Chloride (PAC) is crucial for operational efficiency and cost-effectiveness. As a leading PAC manufacturer and supplier in China, we understand the nuances involved in choosing the right PAC product. This guide aims to demystify the selection process, focusing on key considerations for B2B buyers looking to purchase PAC.

Understanding PAC: The Basics

Polyaluminium Chloride (PAC) is a highly effective inorganic polymer coagulant used extensively in water purification. Its primary function is to destabilize colloidal particles in water, causing them to aggregate into larger flocs that can be easily removed through sedimentation or filtration. This process is vital for treating both potable and industrial wastewater.

Key Factors for PAC Selection

When you are looking to buy PAC, several critical factors should guide your decision:

  • Appearance and Purity: PAC is commonly available as white, light yellow, or yellow powder. White PAC generally indicates higher purity and is often preferred for drinking water applications, while yellow or light yellow variants are suitable for industrial wastewater. Always check the AL2O3 content, which indicates the product's efficacy.
  • Basicity: Basicity refers to the concentration of hydroxyl groups relative to aluminum ions. Higher basicity typically means lower aluminum content and improved performance in contaminant removal, leading to fewer aluminum residuals.
  • Applications: Different grades of PAC are optimized for specific applications. For instance, PAC with a high AL2O3 content and specific basicity is ideal for drinking water, while other formulations might be better suited for papermaking, textiles, or oil field wastewater. Understanding your specific treatment needs is paramount when you plan to purchase PAC.
  • CAS Number and Standards: Ensure the PAC you are sourcing complies with relevant national and international standards (e.g., GB15892-2009 for drinking water grade). The CAS number 1327-41-9 is standard for Polyaluminium Chloride.
