For businesses involved in water treatment, selecting the appropriate coagulant is paramount to achieving efficient and cost-effective results. Poly Aluminium Chloride (PAC) has emerged as a leading solution, often surpassing traditional chemicals like aluminum sulfate. As a dedicated manufacturer and supplier based in China, we understand the critical factors that influence purchasing decisions for PAC. This guide aims to equip procurement managers and R&D scientists with the knowledge to buy the right PAC for their specific needs.

Understanding the Different Types of PAC

PAC is not a monolithic product; it varies in its properties based on manufacturing processes and intended applications. Generally, PAC is categorized by its appearance and basicity. The most common forms include:

  • Yellow PAC: This is the most widely used type for general industrial wastewater treatment. It offers excellent flocculation at a competitive price, making it a popular choice for large-scale applications. It's highly effective in removing suspended solids and turbidity in challenging industrial effluents.
  • White PAC: This form is typically characterized by higher purity and is preferred for more sensitive applications such as drinking water purification, food-grade processes, and certain high-purity industrial water systems. While its price may be higher, its superior performance and lower residual aluminum content are often worth the investment for specialized requirements.

Key Considerations When Purchasing PAC

When you decide to purchase PAC, several technical specifications and supplier attributes should be evaluated:

  • Al2O3 Content: A higher Al2O3 content generally indicates a more potent coagulant, requiring lower dosages. Ensure the product meets the specific concentration needed for your treatment goals.
  • Basicity: This refers to the concentration of hydroxyl groups relative to aluminum ions. Higher basicity often correlates with better performance in contaminant removal and less residual aluminum.
  • Solubility and Form: PAC is available in powder and liquid forms. Powdered PAC requires dissolution, while liquid PAC is ready to use. Consider your storage and dosing capabilities when making your choice.
  • Certifications: For critical applications like drinking water, look for PAC that meets international standards (e.g., NSF/ANSI 60, WQA) and comes with necessary quality assurance certifications.
  • Supplier Reliability: Partnering with a reputable supplier like us ensures consistent quality, timely delivery, and technical support. We pride ourselves on being a dependable source for PAC in China.

Applications Driving Demand for PAC

The versatility of PAC is evident in its widespread use across various sectors:

  • Industrial Water Treatment: From paper mills and textile dyeing to mining and oil refining, PAC is essential for treating complex industrial wastewaters.
  • Municipal Water & Wastewater: It plays a vital role in purifying drinking water sources and treating municipal sewage, contributing to public health and environmental protection.
  • Other Industries: PAC also finds applications in sectors like sugar refining, cosmetics, and even as a raw material in certain manufacturing processes.

Securing the Best Value: Manufacturer vs. Distributor
