Navigating the complexities of industrial water treatment often leads to the crucial decision of selecting the right coagulant. Among the most effective and widely adopted is Poly Aluminium Chloride (PAC). As a leading manufacturer and supplier of water treatment chemicals in China, understanding the nuances of PAC is key to optimizing your processes. This guide aims to assist procurement managers and R&D scientists in making informed choices when looking to buy PAC.

What is Poly Aluminium Chloride (PAC)?

Poly Aluminium Chloride is an inorganic polymer flocculant that has revolutionized water treatment. Its effectiveness stems from its highly charged polymeric structure, which efficiently destabilizes and aggregates suspended solids, colloidal matter, and dissolved organic impurities. Unlike traditional coagulants like aluminum sulfate (alum), PAC offers superior performance, particularly in challenging water conditions.

Understanding PAC Specifications: Al2O3 Content and Basicity

When evaluating PAC, two key specifications stand out: the Al2O3 content and the basicity. The Al2O3 content, often expressed as a percentage, indicates the concentration of aluminum oxide, a primary active component. A higher Al2O3 content generally signifies a more concentrated product. Basicity, on the other hand, refers to the ratio of hydroxyl groups to aluminum ions, reflecting the degree of polymerization. Higher basicity usually means a more efficient product with lower residual aluminum and less impact on water pH.

For industrial applications, understanding your specific water quality parameters—such as turbidity, pH, temperature, and the nature of contaminants—is vital for selecting the optimal PAC grade. For instance, if you are treating wastewater with heavy organic pollution or operating in low-temperature conditions, a PAC with specific basicity and Al2O3 content will yield better results.

Key Applications and Benefits

The versatility of PAC makes it indispensable across various industries:

  • Industrial Wastewater Treatment: Effectively removes pollutants, heavy metals, and suspended solids, helping facilities meet environmental discharge standards.
  • Drinking Water Purification: Ensures safe potable water by efficiently removing turbidity, color, and organic matter, making it a preferred choice for municipal water treatment plants.
  • Mine Water Treatment: Aids in purifying mine wastewater and improving water recycling, thereby reducing operational costs and environmental impact.
  • Paper and Pulp Industry: Used as a sizing agent and for treating process water and effluents.

The benefits of using PAC include faster floc formation, quicker settling times, reduced sludge volume, and a broader effective pH range compared to alum. This translates to improved plant capacity, lower chemical dosing, and reduced overall operating expenses. When looking to purchase PAC, considering these advantages is paramount.
