For procurement managers and R&D scientists in the chemical and manufacturing sectors, selecting the correct water treatment chemicals is paramount. Polyaluminium Chloride (PAC) stands out as a highly effective coagulant, indispensable for tackling a wide array of industrial water purification challenges. Understanding the nuances between different PAC grades is crucial for optimizing treatment processes and achieving cost efficiencies. As a dedicated PAC manufacturer and supplier, we aim to illuminate the key considerations for buyers.

Understanding PAC's Core Functionality
Polyaluminium Chloride, commonly abbreviated as PAC, is an inorganic polymer coagulant. Its primary role is to destabilize and aggregate suspended solids, colloidal matter, and dissolved organic pollutants in water. This process, known as flocculation, leads to the formation of larger, settleable flocs that can be easily removed through sedimentation or filtration. The efficiency of PAC is often linked to its aluminum oxide (Al2O3) content and its basicity – a measure of the hydroxyl groups relative to aluminum ions.

Key Factors for Industrial Buyers
When looking to purchase PAC, several factors should be at the forefront of your decision-making process:

  • Grade and Purity: PAC is available in various grades, typically distinguished by color (e.g., yellow, white) and purity. Industrial-grade PAC, often yellow, is cost-effective and widely used for applications like wastewater treatment, paper production, and textile effluent management. High-purity, white PAC is generally reserved for drinking water or more sensitive applications where minimal impurities are critical. As a reputable PAC supplier, we offer industrial-grade yellow PAC that meets stringent quality standards for performance.
  • Al2O3 Content and Basicity: The percentage of aluminum oxide (Al2O3) directly influences PAC's coagulating power. Higher Al2O3 content generally indicates a more potent product. Basicity is also vital; higher basicity often correlates with increased polymer content and greater efficiency in contaminant removal, while potentially having lower aluminum residuals. Understanding the specific requirements of your wastewater or process water will guide the selection of the optimal Al2O3 content and basicity for your needs.
  • Application Specifics: While PAC is versatile, its optimal performance can vary depending on the target contaminant and industry. For instance, in industrial wastewater, PAC effectively removes heavy metals and oils. In the paper industry, it aids in water recycling and retention. For textile dyeing, it helps in decolorization and COD reduction. Knowing your specific application will help determine the most suitable PAC product.
  • Supplier Reliability and Pricing: As a leading PAC manufacturer in China, we understand the importance of consistent supply and competitive pricing for industrial procurement. Partnering with a reliable manufacturer ensures you receive quality products consistently, avoiding disruptions to your operations. We are committed to providing excellent value, making high-performance PAC accessible for your bulk purchase needs.

Optimizing Your PAC Purchase
To secure the best results and value, consider performing jar tests with different PAC products to determine the optimal dosage and grade for your specific water matrix. Always consult with your PAC supplier for technical data sheets and expert advice.
