For procurement managers and R&D scientists in industries reliant on water treatment, understanding the specifications and pricing of Polyaluminum Chloride (PAC) is critical for making informed purchasing decisions. PAC is a versatile coagulant widely used for its efficiency in clarifying water. NINGBO INNO PHARMCHEM CO.,LTD., a prominent chemical manufacturer based in China, offers high-quality PAC and is committed to transparency regarding its product's characteristics and market pricing.

Decoding Polyaluminum Chloride (PAC) Specifications

The performance of PAC in water treatment is directly linked to its specific chemical composition. Key parameters that buyers should always inquire about include:

  • Aluminum Oxide (Al2O3) Content: This is a primary indicator of PAC's coagulating power. Higher Al2O3 content generally translates to higher efficacy in removing turbidity and suspended solids. For industrial grade PAC, you might typically find Al2O3 content ranging from 26-28% or 30%.
  • Basicity: Basicity, often expressed as a percentage, refers to the degree of hydrolysis of the aluminum ions. It influences the charge neutralization and bridging mechanisms during coagulation. Different water conditions may require PAC with varying basicity levels (e.g., 60-95%).
  • pH (1% Aqueous Solution): The pH value indicates the acidity of the PAC solution. This is important as it affects the overall pH of the treated water, potentially influencing the need for pH adjustment chemicals. A typical range for PAC is 3.5-5.0.
  • Water Insoluble Matter: This refers to the percentage of the product that does not dissolve in water. A lower percentage signifies a purer, more concentrated product, leading to better performance and less residue.
  • Heavy Metal Impurities: For drinking water grade PAC, strict limits are placed on heavy metals such as Iron (Fe), Arsenic (As), Lead (Pb), Cadmium (Cd), Mercury (Hg), and Chromium (Cr). Manufacturers must provide assay results for these.

When you search to buy PAC, always request a Certificate of Analysis (CoA) to verify these specifications. NINGBO INNO PHARMCHEM CO.,LTD. provides comprehensive CoAs for all our PAC products.

Factors Influencing PAC Pricing

The price of Polyaluminum Chloride is influenced by several factors, including raw material costs, production scale, product grade (industrial vs. drinking water), purity levels, and market demand. As a large-scale manufacturer, we leverage economies of scale to offer competitive PAC water treatment prices.

When comparing prices, consider the following:

  • Volume Discounts: Purchasing larger quantities, such as from 25,000-49,999 kg up to 75,000+ kg, typically secures more favorable pricing per unit, as seen in tiered pricing structures.
  • Product Grade: Drinking water grade PAC, due to stricter purity requirements and production processes, may command a higher price than industrial grade.
  • Packaging: While standard packaging (e.g., 25kg, 50kg, 1000kg bags) is common, custom packaging might incur additional costs.
  • Supplier Reputation: Reputable manufacturers with strong quality certifications and reliable supply chains often offer better long-term value, even if their initial price point is slightly higher.
