Product Description:
Polyaluminum Ferric Chloride (PAFC) is an inorganic polymeric coagulant synthesized by combining aluminum salts (Al³⁺) and iron salts (Fe³⁺). It integrates the advantages of both aluminum-based coagulants (e.g., PAC) and iron-based coagulants (e.g., PFS), offering enhanced coagulation efficiency and adaptability.
PAFC is widely used in water and wastewater treatment due to its stable chemical structure, high charge density, and rapid formation of dense flocs. Its development addresses limitations of traditional coagulants, such as narrow pH tolerance and residual metal ions, making it a versatile solution for modern environmental challenges.
Features:
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
Drinking water treatment involves the removal of suspended solids, pathogens, and organic contaminants to ensure water safety.
Case Example
A plant in China successfully achieved 95% turbidity removal using PAFC at a concentration of 15 mg/L, meeting the standards set by GB5749-2022.
Industrial Wastewater Treatment
Industrial wastewater treatment applications vary, such as:
- Textile Dyeing: Degrades azo dyes and achieves over 85% COD removal.
- Petrochemical: Efficient in oil-water separation and heavy metal adsorption, with 80-95% Pb²⁺ removal.
- Paper/Pulp: Reduces lignin and suspended fibers, resulting in a 70% BOD reduction.
Municipal Wastewater Treatment
Municipal wastewater treatment processes tackle sewage and stormwater, aiming to combat eutrophication by removing phosphorus (60-80% reduction).
Sludge Conditioning
Sludge conditioning enhances dewatering efficiency, reducing sludge volume by 30-50% and cutting down disposal costs.
Niche Uses
Specialized uses of this treatment method include:
- Mining: Treating acid mine drainage by adjusting pH levels and precipitating metals.
- Food Processing: Clarifying wastewater with high organic loads, like dairy effluent.
Comparative Advantages
This treatment technology offers advantages compared to other methods:
- vs. PAC: Outperforms in low-temperature/high-turbidity water conditions.
- vs. PFS: Results in less residual color and reduced corrosion, without yellowing of water.
- vs. Alum: Requires lower dosage, settles faster, and operates effectively over a broader pH range.
Environmental & Safety Considerations
When handling this treatment technology, it is important to:
- Use appropriate Personal Protective Equipment (PPE) to prevent inhalation/contact.
- Store the treatment chemicals in corrosion-resistant containers, adhering to safety guidelines.
Regulatory Compliance and Research Trends
This treatment technology meets regulatory standards by organizations such as the EPA and the EU for coagulants in drinking water. Emerging research trends include the development of nano-PAFC hybrids and bio-polymer composites to target pollutants more effectively.
