Poly Aluminium Chloride (PAC) has emerged as a cornerstone chemical in various industrial sectors, most notably in water treatment, but also extending into papermaking, cosmetics, and the oil and gas industry. Its effectiveness as a coagulant, flocculant, and demulsifier stems from its unique polymeric structure and high charge density. For procurement managers, R&D scientists, and formulation specialists, understanding PAC's characteristics and how to source it effectively is crucial. As a leading manufacturer and supplier, we aim to provide a comprehensive overview for potential buyers.

What is Poly Aluminium Chloride (PAC)?

PAC is an inorganic polymer coagulant with the general formula [Aln(OH)mCl(3n-m)]x. It is essentially a highly polymerized form of aluminum chloride, often produced through the reaction of aluminum hydroxide with hydrochloric acid. The degree of polymerization and the ratio of hydroxyl to aluminum ions (basicity) determine its specific properties and applications. PAC is typically available in powder or liquid form, commonly in yellow, beige, or white colors, with varying concentrations (e.g., 28%, 30% Al2O3 content).

Key Advantages of Using PAC:

  • Superior Coagulation Efficiency: PAC forms denser, faster-settling flocs compared to traditional coagulants like aluminum sulfate (alum). This leads to improved turbidity removal and overall water clarity.
  • Broad pH Applicability: PAC performs effectively across a wide pH range, minimizing the need for extensive pH adjustments and reducing associated chemical costs.
  • Reduced Sludge Production: One of PAC's most significant benefits is its ability to generate less sludge than conventional coagulants, lowering sludge handling, dewatering, and disposal expenses.
  • Cost-Effectiveness: Lower dosage requirements and reduced need for pH adjustment chemicals often make PAC a more economical choice in the long run, despite potentially higher initial unit costs than alum.
  • Performance in Cold Water: PAC maintains its efficacy in cold water conditions, a distinct advantage over alum, which can see its performance significantly diminish in low temperatures.
  • Versatile Applications: Beyond water treatment, PAC finds use in papermaking (retention aid, wastewater treatment), cosmetics (antiperspirants), and oil & gas (demulsification).

How to Buy Poly Aluminium Chloride Effectively

For businesses seeking to purchase PAC, especially in bulk quantities, several factors are important to consider:

  • Supplier Reputation and Quality Control: Partner with established manufacturers and suppliers who have stringent quality control measures in place. Look for suppliers that provide certificates of analysis (CoA) and adhere to international standards. As a leading China-based manufacturer, we pride ourselves on consistent quality and product reliability.
  • Product Specifications: Understand the specific grade of PAC required for your application. Key specifications include Al2O3 content, basicity, pH, water insolubles, and color. Discuss your application needs with potential suppliers to identify the most suitable product.
  • Pricing and Negotiation: Obtain quotes from multiple suppliers, comparing not just the unit price but also factoring in delivery costs, payment terms, and minimum order quantities (MOQ). For bulk purchases, negotiation is often possible.
  • Technical Support and Customization: A good supplier will offer technical support to help optimize PAC usage and may even offer customized formulations to meet unique operational challenges.
  • Logistics and Lead Times: Ensure the supplier has a robust logistics network to guarantee timely delivery, especially for critical industrial processes.
