Nature

• Physical properties:
  • State: Fine powder.
  • Color: Light yellow.
  • Solubility: Easily soluble in water, forming a clear or slightly cloudy solution.
  • Desiccant: PAC powder is highly hygroscopic and needs to be kept sealed and dry.
• Chemical properties:
  • Main ingredient: Polyaluminium chloride compound.
  • Al₂O₃ content: Fluctuates around 28% – 31%.
  • Basicity: About 40% – 85%.
  • pH (1% solution): About 3,5 – 5,0.
  • Stability: When exposed to strong alkaline solutions, PAC can be further hydrolyzed and form aluminum hydroxide precipitates, reducing treatment efficiency.

Application of China PAC

• Water treatment: Remove impurities and bacteria in river, lake and well water to provide standard domestic water.
• Industrial wastewater treatmentEffective in coagulating and settling pollutants in wastewater from paper mills, dyeing factories, and food processing plants, helping wastewater meet standards before being discharged into the environment.
• Aquaculture: Improve pond water quality, reduce organic matter and pathogenic bacteria content, create a good living environment for shrimp and fish.
• Paper productionUsed as a settling agent, helps remove impurities during the production process, improving the quality of finished paper.

Chinese PAC User Manual

1. Solution preparation: Dissolve PAC in clean water to create a 5-10% solution.
2. Dosage:
   • Water treatment: Depending on the turbidity of the raw water, use 1-10g PAC/m³ of water.
   • Wastewater treatment: Depending on the suspended matter content and wastewater properties, use 20-200g PAC/m³ of water.
3. The Franchising Process:
   • Add the mixed PAC solution to the water source to be treated, stir well to disperse the chemicals, let it sit for the coagulation and sedimentation process to take place, then remove the sediment and collect clear water.

Safety in use and storage

• Wear full protective gear such as gloves, goggles, and chemical-resistant clothing when working with PAC.
• Avoid direct contact of chemicals with skin and eyes. If this occurs, rinse immediately with clean water and seek medical attention if necessary.
• Use PAC at the recommended dosage to ensure effectiveness and safety.
• Store PAC in a cool, dry place, away from direct sunlight and high temperatures; close the packaging after use to avoid moisture absorption as PAC has strong hygroscopic properties.

FAQ – Frequently Asked Questions about China PAC

• Can Chinese PAC completely replace alum in water treatment?
  • Yes, Chinese PAC can replace alum (Al2(SO4)3) in water treatment, even with superior efficiency. Due to its high aluminum content (28-31% Al₂O₃), PAC has stronger coagulation ability, faster settling speed and larger flocculation than alum. In addition, when using PAC, the amount of sludge is less, helping to save costs on sludge treatment and pH neutralization chemicals.
• What is the difference between powder PAC and liquid PAC?
  • PACs come in two common forms:
    • Powder form: Contains higher Al₂O₃ content (28-31%), suitable for large-scale water treatment systems or high performance requirements.
    • Liquid: Usually has lower Al₂O₃ content (10-18%), is easy to use and suitable for small scale water treatment systems or those requiring tighter dosing control.
  • Powder form has the advantage of performance and longer shelf life, while liquid form is easier to mix and more convenient to use.
• Does Chinese PAC affect aquatic ecosystems when discharged?
  • PAC, when used in the correct dosage, will not have a negative impact on the aquatic ecosystem. However, if used excessively or handled improperly, excess aluminum can accumulate in the water, affecting microorganisms and aquatic organisms. Therefore, it is necessary to control the amount of PAC used and ensure that the sedimentation process is fully completed before discharging into the environment.
• Can Chinese PAC be used in the treatment of industrial wastewater containing heavy metals?
  • Yes, PAC is capable of precipitating and removing a wide range of heavy metals such as iron, manganese, lead and copper from industrial wastewater. When combined with coagulants such as anionic or cationic polymers, the heavy metal removal efficiency can be significantly enhanced. However, field trials are needed to determine the optimal dosage for each type of wastewater.
• What quality standards should I check when purchasing Chinese PAC?
  • When choosing to buy Chinese PAC, the following criteria should be considered to ensure product quality:
    • Al₂O₃ content: Should be 28-31% for powder form and 10-18% for liquid form.
    • pH (1% solution): Fluctuates from 3.5 – 5.0 to ensure good coagulation performance.
    • Solubility: Completely soluble in water, no residue or insoluble matter.
    • Heavy metal content: Check indicators such as Pb, As, Hg to ensure they do not exceed the allowable levels.
    • Quality certification: PAC meets ISO, NSF or other water treatment related certifications.
  • In addition, it should be requested MSDS (Material Safety Data Sheet) , and COA (Certificate of Analysis) from suppliers to verify product origin and quality.
