Poly Aluminum Chloride

---

Poly Aluminium Chloride (PAC) is a widely used chemical in water treatment, typically represented by the molecular formula [Al₂(OH)_nCl_6-n]_m. Its main characteristics include strong alkalinity and high charge cation, which can effectively neutralize the negative charges on the surface of suspended solids in water, promoting coagulation and sedimentation. The advantage of PAC lies in its multi-core polymer structure, which provides strong bridging capabilities, rapidly forming flocs and accelerating the sedimentation process, thereby improving water treatment efficiency. Compared to traditional water treatment agents, PAC is about three times more effective than aluminum sulfate, with reduced dosage and simplified treatment equipment, significantly enhancing overall treatment capacity. This chemical not only excels in wastewater treatment but also demonstrates superior performance in many other fields, making it an indispensable material in environmental protection and industrial production.

Poly Aluminium Chloride, known as PAC in the international market, is also widely used globally. As an efficient water treatment agent, PAC's application in industrial water treatment is becoming increasingly common, effectively removing turbidity and microorganisms from water to ensure safety and cleanliness.

Wastewater Treatment Applications

---

Poly Aluminium Chloride (PAC) is particularly suitable for treating complex water quality environments such as textile dyeing wastewater, urban sewage, and industrial wastewater. PAC's high bridging ability and strong coagulation characteristics enable it to quickly remove suspended solids and colloidal particles from water, significantly improving water quality. Its specific advantages include rapid floc formation, accelerated sedimentation, reduced dosage, and enhanced overall treatment efficiency. Using PAC makes the water treatment process more efficient and economical, with a greatly reduced environmental impact. This makes PAC a popular choice in wastewater treatment, improving treatment effects and reducing operational costs. While the hazards of Poly Aluminium Chloride are relatively low, precautions should still be taken during use to avoid prolonged contact.

• Rapid floc formation
• Accelerated sedimentation process
• Reduced dosage

Therefore, using Poly Aluminium Chloride to treat wastewater not only effectively removes pollutants but also saves a significant amount of treatment costs, making it the best choice for both environmental and economic benefits.

For metal ions and organic pollutants in groundwater, PAC is also effective in removing color and turbidity from the water. Its high efficiency in removing metal ions and reducing organic content makes it particularly outstanding in groundwater treatment. By using PAC, pollutants in the water can be quickly and effectively removed, improving the color and turbidity of the water. This is especially significant for areas requiring high-quality industrial water. Additionally, PAC's application in groundwater treatment is not only a technical advancement but also a significant contribution to environmental protection. Poly Aluminium Chloride has a wide range of applications, particularly prominent in groundwater treatment.

• High-efficiency removal of metal ions
• Reduction of organic content
• Improvement of water color and turbidity

In summary, the application of PAC not only improves the efficiency of groundwater treatment but also contributes significantly to improving water quality and protecting the environment.

In casting processes, PAC can be used for treating foundry sand, improving the quality of the molds, and enhancing the surface smoothness of castings. Its high-efficiency coagulation and bridging properties allow for the rapid removal of impurities in foundry sand, improving mold stability and strength. The foundry sand treated with PAC can significantly enhance the surface quality of castings, reduce defect rates during production, and improve overall production efficiency. This is crucial for enterprises pursuing high-quality castings. Additionally, the application of PAC in the casting industry reduces the usage of chemicals during the production process, thereby lowering production costs and increasing economic benefits. Overall, the application of PAC in the casting industry offers significant advantages in improving product quality, reducing costs, and promoting environmental protection. The use of Poly Aluminium Chloride in the casting industry is becoming increasingly widespread, demonstrating its great potential as an efficient, economical, and environmentally friendly chemical.

• Improvement of mold quality
