Polyaluminium Chloride (PAC) is a powerful and versatile coagulant widely used in water treatment. However, not all PAC products are created equal. They come in various grades, each tailored for specific applications and water conditions. As a leading manufacturer and supplier of Polyaluminium Chloride, we aim to guide you in selecting the most appropriate PAC grade to ensure optimal performance and cost-effectiveness in your water treatment processes.

Understanding PAC Grades and Specifications

PAC products are primarily differentiated by their physical form (e.g., spray-dried, roller-dried), color (e.g., yellow, white, light yellow), Alumina (Al2O3) content, and Basicity. These specifications dictate their suitability for different water treatment scenarios:

• Alumina (Al2O3) Content: This parameter indicates the concentration of aluminum oxide in the PAC, which is directly related to its coagulating power. Higher Al2O3 content generally means greater efficiency. Typical values range from 28% to 31%.
• Basicity (%): Basicity refers to the degree of hydrolysis of the aluminum chloride. It influences the charge neutralization capability and the formation of polymeric species. Higher basicity generally leads to more efficient coagulation and less residual aluminum. Values can range from 40% to over 90%.
• Water Insolubles (%): This specifies the amount of material in the PAC that does not dissolve in water. Lower water insolubles are preferred for applications requiring high purity and rapid dissolution.
• Color: While color can be an indicator, it's important to note that different colors (yellow, light brown, white) correspond to different production processes and purity levels. White PAC, for example, is often produced from purer raw materials and is preferred for potable water treatment.

Key PAC Grades and Their Applications

Based on these specifications, PAC can be broadly categorized:

• PAC-Spray Dried (Yellow/Light Yellow/Brown): These are commonly used for industrial wastewater treatment, sewage treatment, and in industries like paper making. They offer a good balance of performance and cost.
• PAC-Roller Dried (Light Brown): Similar to spray-dried PAC, these are suitable for general industrial water treatment.
• PAC-White (High Purity): White PAC is typically produced using purer raw materials and processes, resulting in lower water insolubles and often higher basicity. It is the preferred choice for drinking water purification and high-purity industrial water applications where minimal contamination is critical.

Selecting the Right PAC for Your Needs

When choosing a PAC grade, consider the following:

• Water Source Quality: The turbidity, pH, and contaminant profile of your raw water will dictate the required PAC dosage and type.
• Treatment Objective: Whether you are treating potable water, industrial wastewater, or process water will determine the purity and specific performance requirements.
• Cost-Effectiveness: Balance the performance benefits with the price. Our competitive PAC chemical prices ensure you get the best value.
