PAFC is an inorganic polymeric coagulant created through the combination of aluminum salts (Al³⁺) and iron salts (Fe³⁺). It brings together the benefits of aluminum-based coagulants like PAC and iron-based coagulants such as PFS, resulting in improved coagulation efficiency and versatility.
One of the key reasons for the widespread use of PAFC in water and wastewater treatment is its stable chemical structure, high charge density, and quick formation of dense flocs. These qualities enable PAFC to overcome the limitations associated with traditional coagulants, such as narrow pH tolerance and the presence of residual metal ions.
PAFC's development represents a significant step forward in addressing modern environmental challenges, making it a flexible and effective solution for various treatment needs.
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.
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.
