China Polymeric Aluminium Ferric Chloride (PAFC) from China Suppliers - Ideal Water Treatment Solution from Factory Manufacturer, Factory
Introducing our advanced inorganic polymer composite, designed specifically for effective water treatment solutions. As a leading supplier in China, we offer this unique product, which is formulated using polyaluminum chloride and complexed with polymeric iron. This innovative combination enhances the molecular structure, significantly improving electro-neutralization, bridging adsorption, and sedimentation performance. Our product is the ideal choice for treating source water with severe organic pollution, as well as water sources characterized by low temperature and varying turbidity levels. Trust our factory to provide high-quality, efficient solutions for your water treatment needs
PAFC deeply integrates the dual advantages of aluminum ions (Al³⁺) and iron ions (Fe³⁺), addresses the limitations of single flocculants, and its core performance is as follows:
1. Aluminum-iron synergy enhances flocculation efficiency by over 30%.
Double-charge adsorption: Al³⁺ adsorbs negatively charged colloids (such as clay and humic acid) through "electrical neutralization"; Fe³⁺ captures fine particles (such as organic matter and microorganisms) through "net capture", forming flocs that are denser and settle faster (settling velocity ≥ 25 m/h).
Wide pH Adaptability: Applicable pH range is 4-10 (optimal 6-9), resistant to high turbidity (≤10000 NTU), high salinity (e.g., seawater desalination pretreatment), and high organic matter (e.g., printing and dyeing/paper mill wastewater) water quality, covering over 90% of global water treatment scenarios.

Frequently Asked Questions
Q
What is PAFC and how does it differ from regular PAC (Polyaluminum Chloride)?
PAFC (Polyaluminum Ferric Chloride) is a composite flocculant that combines the properties of both aluminum ions (Al³⁺) and iron ions (Fe³⁺). Unlike standard PAC, which relies solely on aluminum-based coagulation, PAFC leverages a dual-charge adsorption mechanism — Al³⁺ neutralizes negatively charged colloids while Fe³⁺ captures fine particles through net capture. This synergy enhances flocculation efficiency by over 30% compared to single-component flocculants.
Q
What is the recommended pH range for using PAFC in water treatment?
PAFC is effective across a wide pH range of 4–10, with the optimal performance achieved between pH 6 and 9. This broad adaptability makes it suitable for treating high turbidity water (≤10,000 NTU), high-salinity water such as seawater desalination pretreatment, and high organic-load wastewater including printing, dyeing, and paper mill effluents — covering over 90% of global water treatment scenarios.
Q
What industries or applications is PAFC most suitable for?
PAFC is widely used across municipal and industrial water treatment sectors. Key applications include municipal sewage treatment (SS reduction, partial COD removal), printing and dyeing wastewater decolorization, electroplating and chemical wastewater treatment (removal of heavy metals such as Cr⁶⁺ and Cu²⁺), paper mill and mining wastewater clarification, and food processing wastewater treatment (removal of starch and protein suspended solids).
Q
What are the available packaging options for PAFC?
PAFC is available in both liquid and solid forms. The liquid type is packaged in 200L plastic drums, 1000L IBC totes, or flexible liquid bags. The solid type is supplied in 25kg woven bags (with inner plastic lining) or 1-ton jumbo bags. Custom branding with customer logos and English labels is available for the solid packaging upon request.
Q
How should PAFC be stored to maintain its quality and shelf life?
The liquid type should be stored in a sealed container in a cool, well-ventilated area at temperatures ≤30°C, away from direct sunlight and fire sources. The solid type should be stored in a dry warehouse with humidity ≤60%, protected from moisture and physical damage, and stacked no more than 2 layers high. The shelf life is 12 months for the liquid type (sealed) and 24 months for the solid type (unopened).
Q
What are the key technical specifications for PAFC in both liquid and solid forms?
The key specifications include: Al₂O₃ content ≥8.0% (liquid) / ≥28.0% (solid); Fe mass fraction 1.5–5.0% for both forms; Fe²⁺ mass fraction ≤0.2%; basicity 20–85%; insoluble substances ≤0.5%; pH of 10g/L solution 3.5–5.0. Heavy metal content is strictly controlled: As ≤0.0005%, Cr ≤0.005%, Hg ≤0.00002%, Pb ≤0.002%, and Cd ≤0.0002%, ensuring compliance with water treatment safety standards.
