**Product Introduction** 

 Polymeric aluminum solution (ACH) is a highly concentrated solution of polyaluminum chloride. It features the highest aluminum content on the market at 23% Al2O3 (w/w) among all solution-based aluminum products. ACH also has the highest basicity at 83% compared to any other solution-based polyaluminum chloride. Basicity indicates the extent of acid neutralization and represents the level of polymeric aluminum in ACH. The high polymeric aluminum content in ACH offers a greater cationic charge than standard salts, such as alum or aluminum chloride, and even other polyaluminum products. Therefore, ACH provides enhanced performance while reducing overall dosage. Its high acid neutralization capability (basicity) means that the impact on water pH when using ACH can be considered negligible. Compared to traditional metal salts and low basicity polyaluminum chloride, ACH can effectively coagulate across a broader pH range (up to 9.5). 

 **Applications and Benefits:**

 1. **Urban and Industrial Water Treatment:**

Polymeric aluminum solution is commonly used as the primary coagulant in drinking water and industrial wastewater treatment plants, replacing other coagulants like alum, often eliminating or significantly reducing the need for pH adjustment chemicals, coagulants, and filter aids. ACH is frequently applied in environments with a pH greater than 7.5.  

 **Recognized Benefits of Using Polymeric Aluminum Solution:**   

- Improved turbidity removal   

- Enhanced color removal   

- Increased removal of TOC (Total Organic Carbon)   

- Reduced filtering turbidity   

- Improved filtration cycle   

- Over 50% reduction in sludge   

- Simplified operations, eliminating pH adjustment and secondary polymer electrolyte addition   

- Lower overall treatment costs 

 2. **Urban and Industrial Wastewater Treatment:**   

Polymeric aluminum can also be applied in wastewater treatment for:   

- Removal of TSS (Total Suspended Solids)   

- Metal removal   

- Phosphorus removal   

- Decrease in COD (Chemical Oxygen Demand) in industrial wastewater   

- Removal of BOD (Biochemical Oxygen Demand) and TOC in municipal wastewater 

 3. **Pulp and Paper Manufacturing Applications:**   

Polymeric aluminum solution can be utilized in various mechanical applications such as:   

- Sizing adhesives   

- Anionic trash removers   

- Retention and filtration aids   

- Resin barrier control additives   

- Papermaking sizing precipitant

 4. **Silicon Wafer Polishing Liquids** 

 5. **Raw Material for Antiperspirants:**   

Cosmetic-grade ACH is widely used as a raw material in antiperspirants.
