Polyaluminum Ferric Chloride Mining Applications

Synergistic Coagulation Mechanism:
Combines the rapid flocculation of aluminum salts with the strong adsorption and dense flocs of iron salts, improving sedimentation speed and effluent clarity.

Broad pH Adaptability:
Effective across pH 4–10, reducing the need for pH adjustment in most water types.

Low Residual Aluminum/Iron:
Minimizes secondary pollution risks, crucial for drinking water safety and compliance with regulations (e.g., WHO guidelines for residual Al <0.2 mg/L).

High Efficiency in Turbidity and Color Removal:
Removes colloidal particles, organic matter, and dyes effectively, achieving >90% turbidity reduction in optimal conditions.

Temperature Resilience:
Performs well in low-temperature (≤5°C) or high-salinity water, unlike conventional coagulants that may fail under such conditions.

Reduced Corrosivity:
Less corrosive to equipment compared to FeCl₃, lowering maintenance costs.

Cost-Effectiveness:
Lower dosage requirements (typically 10–50 mg/L) translate to operational savings.

Applications:

Drinking Water Treatment
Removes suspended solids, pathogens, and organic contaminants.

Case Example: A plant in China achieved 95% turbidity removal using PAFC at 15 mg/L, meeting GB5749-2022 standards.

Industrial Wastewater
Textile Dyeing: Degrades azo dyes; achieves >85% COD removal.

Petrochemical: Efficient in oil-water separation and heavy metal adsorption (e.g., 80–95% Pb²⁺ removal).

Paper/Pulp: Reduces lignin and suspended fibers, lowering BOD by 70%.

Municipal Wastewater
Treats sewage and stormwater, removing phosphorus (60–80% reduction) to combat eutrophication.

Sludge Conditioning
Enhances dewatering efficiency, reducing sludge volume by 30–50% and lowering disposal costs.

Niche Uses
Mining: Treats acid mine drainage (AMD) by neutralizing pH and precipitating metals.
Food Processing: Clarifies wastewater with high organic loads (e.g., dairy effluent).

Comparative Advantages
vs. PAC: Better performance in low-temperature/high-turbidity water.
vs. PFS: Less residual color (no yellowing of water) and lower corrosion.
vs. Alum: Lower dosage, faster settling, and broader pH range.

Environmental & Safety Considerations
Handling: Use PPE to avoid inhalation/contact; store in corrosion-resistant containers.
Regulatory Compliance: Meets EPA and EU standards for coagulants in drinking water.
Research Trends: Nano-PAFC hybrids and bio-polymer composites for enhanced pollutant targeting.
