Poly Aluminum Ferric Chloride (PAFC) | Flocculation & Sludge Dewatering for Industrial Wastewater
Poly Aluminum Ferric Chloride | PAFC
High-efficiency aluminum–iron composite coagulant designed for stable coagulation, rapid flocculation, and reliable solid–liquid separation in drinking water and wastewater treatment systems.
What Is Poly Aluminum Ferric Chloride (PAFC)?
Poly Aluminum Ferric Chloride (PAFC) is a high-performance inorganic polymer coagulant developed by combining the hydrolysis mechanisms of aluminum salts and iron salts.
As a professional PAFC manufacturer and supplier, we provide aluminum–iron composite coagulants with a high degree of polymerization and stable ionic structure.
By integrating aluminum ions with ferric ions, PAFC forms dense, fast-settling flocs with strong adsorption capacity. Compared with conventional coagulants such as PAC, aluminum sulfate, and ferric chloride, PAFC delivers more stable coagulation performance, especially under low-temperature, low-turbidity, and fluctuating water quality conditions.
PAFC is widely used in drinking water purification, municipal sewage treatment, industrial wastewater treatment, and sludge conditioning processes.
Key Features of PAFC Coagulant High-Efficiency Aluminum–Iron Composite Structure
Combines the advantages of aluminum-based and iron-based coagulants to achieve rapid hydrolysis and strong floc formation.
Wide Water Quality Adaptability
Maintains stable performance in high-turbidity, low-turbidity, and low-temperature water conditions.
Low Residual Aluminum
Helps treated water meet drinking water and discharge standards.
Dense Flocs & Fast Settling
Produces compact flocs with good settling and filtration characteristics.
Lower Dosage, Higher Performance
Achieves equivalent or better treatment results with lower chemical consumption.

Main Applications of Poly Aluminum Ferric Chloride
PAFC is widely applied in municipal and rural drinking water plants to remove turbidity, suspended solids, color, and natural organic matter.
It performs reliably under low-temperature and low-turbidity conditions and helps maintain low residual aluminum levels.
Used in primary clarification and advanced treatment stages to improve suspended solids, COD, and phosphorus removal.
PAFC maintains stable operation under fluctuating influent flow and water quality.
Effective for complex industrial effluents including papermaking, textile & dyeing, chemical, metallurgical, and mining wastewater.
Shows strong tolerance to high organic load, color, salinity, and pH fluctuation.
Applied before mechanical dewatering processes to improve sludge floc strength, accelerate water release, and reduce sludge volume.
Less affected by cold water conditions compared with traditional aluminum salts, making it suitable for winter operation and northern regions.
Used as pretreatment to reduce suspended solids, protect downstream equipment, and improve overall system stability.
