Compound Poly Aluminium Chloride
Core Features
1. Multi-effect synergy to address the "shortcomings" of single PAC
• Complete the pH adaptation range: The optimal pH for single PAC is 6-9, while CPAC can extend the applicable pH to 4-11 by adding iron salts (such as polyferric sulfate) or organic bases (such as polyacrylamide), adapting to highly acidic (such as mine wastewater) or highly alkaline (such as papermaking black liquor) scenarios;
• Enhanced Decolorization/Heavy Metal Removal: For printing and dyeing wastewater (containing dye pigments) or electroplating wastewater (containing Cr⁶⁺, Cu²⁺), CPAC can be compounded with activated carbon (adsorbing pigments) or sulfides (complexing heavy metals), with a high heavy metal removal rate;
• Reduce sludge production: Composite components (such as diatomite) can enhance the compactness of flocs, with the sludge volume reduced by 20%-30% compared to single PAC, thereby reducing the subsequent pressure filtration cost.

2. Adapt to complex water quality, covering over 90% of industrial scenarios
Through "Modularization compounding" design, CPAC can flexibly adjust the formula according to different wastewater characteristics, for example:
•High turbidity wastewater (such as coal washing and mining wastewater): Compound high polymerization degree PAC (Al₂O₃ ≥ 15%) + diatomite (enhanced filtration), turbidity removal rate ≥ 98%;
•High organic wastewater (such as printing and dyeing, food processing wastewater): Compound activated carbon (adsorbing COD) + polyacrylamide (coagulant aid), with a COD removal rate ≥ 50%;
•Heavy metal-containing wastewater (such as electroplating and chemical wastewater): compounded sodium sulfide (complexing heavy metals) + iron salt (netting and precipitation).
•High turbidity wastewater (such as coal washing and mining wastewater): Compound high polymerization degree PAC (Al₂O₃ ≥ 15%) + diatomite (enhanced filtration), turbidity removal rate ≥ 98%;
•High organic wastewater (such as printing and dyeing, food processing wastewater): Compound activated carbon (adsorbing COD) + polyacrylamide (coagulant aid), with a COD removal rate ≥ 50%;
•Heavy metal-containing wastewater (such as electroplating and chemical wastewater): compounded sodium sulfide (complexing heavy metals) + iron salt (netting and precipitation).

Precautions for Use
• Water quality testing first: Before use, it is necessary to test the pH, COD, and heavy metal content of wastewater, and adjust the CPAC formula based on the data (for example, acidic wastewater requires an increase in the proportion of iron salts);
• Storage Conditions: Liquid type should be stored sealed in a cool place (temperature ≤ 30°C), solid type should be stacked to prevent moisture (humidity ≤ 60%), and the shelf life of the liquid type is 12 months.
