In the realm of chemical auxiliaries, Polyaluminium Chloride (PAC) stands out as a highly effective and versatile coagulant. For professionals in water treatment, paper manufacturing, and various other industries, understanding the nuances of PAC, particularly its CAS number 1327-41-9, and how to procure it efficiently, is crucial. As a leading manufacturer and supplier of PAC based in China, we are dedicated to providing comprehensive information and top-tier products to meet your operational needs.

What is Polyaluminium Chloride (PAC) and Why is it Important?

Polyaluminium Chloride (PAC) is classified as an inorganic macromolecule flocculant. It is synthesized through the polymerization of aluminum chloride and aluminum hydroxide, resulting in a complex inorganic polymer with a high positive charge. This structure makes it exceptionally effective at neutralizing negative charges present in water, such as those carried by suspended solids, colloidal particles, and dissolved organic matter. When added to water, PAC forms large, gelatinous flocs that entrap impurities, facilitating their removal through sedimentation or filtration.

The significance of PAC, identified by its CAS number 1327-41-9, lies in its superior performance compared to traditional inorganic coagulants like aluminum sulfate or ferric chloride. PAC offers:

  • Wider pH Range: It functions effectively within a broader pH range (5.0-9.0), providing greater operational flexibility.
  • Lower Dosage Requirements: Typically, less PAC is needed to achieve the same level of treatment, leading to cost savings.
  • Improved Floc Formation: Produces denser, stronger flocs that settle more quickly.
  • Reduced Alkalinity Consumption: It has less impact on water alkalinity compared to aluminum sulfate.

Key Applications and Where to Buy PAC

The applications of Polyaluminium Chloride are extensive:

  • Water Treatment: Both drinking water purification and industrial wastewater treatment benefit immensely from PAC's flocculating capabilities. It's used to remove turbidity, color, heavy metals, and organic pollutants.
  • Papermaking: PAC acts as a retention aid and sizing agent, improving paper formation and reducing effluent pollution.
  • Textile Industry: Used in dyeing processes and for treating textile wastewater.
  • Leather Tanning: Serves as a tanning agent or auxiliary.
