Wholesale Polymeric Aluminium Ferric Chloride (PAFC) - Leading China Suppliers & Factory for Water Treatment Solutions Supplier, Factories
This product is a high-performance inorganic polymer composite, specifically formulated from polyaluminum chloride and polymeric iron. As a leading agent among China suppliers, it enhances molecular structure, electro-neutralization, bridging adsorption, and sedimentation capabilities. This makes it an ideal solution for treating source water with significant organic pollution, as well as for addressing challenging conditions such as low temperature and low turbidity or high turbidity. Our factory ensures top-quality production, providing effective water treatment solutions tailored to diverse environmental challenges
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 both aluminum ions (Al3+) and iron ions (Fe3+). Unlike regular PAC which relies solely on aluminum, PAFC leverages dual-charge adsorption – Al3+ neutralizes negatively charged colloids while Fe3+ captures fine particles via net capture – resulting in over 30% higher flocculation efficiency, denser flocs, and faster settling speeds.
Q
What pH range is PAFC effective in?
PAFC is effective across a broad pH range of 4–10, with the optimal performance between pH 6–9. This wide adaptability makes it suitable for treating high turbidity (≤ 10,000 NTU), high salinity, and high organic matter wastewater, covering over 90% of global water treatment scenarios.
Q
What types of wastewater can PAFC treat?
PAFC is widely applicable across multiple industries. It is used for municipal sewage (SS reduction, partial COD removal), printing and dyeing wastewater (decolorization), electroplating and chemical wastewater (heavy metal removal), paper mill and mining wastewater (white water recovery), and food processing wastewater (starch/protein suspended solids removal).
Q
What are the available packaging options for PAFC?
PAFC is available in both liquid and solid forms. Liquid PAFC is packaged in 200L plastic drums, 1000L IBC totes, or flexible liquid bags. Solid PAFC is available in 25kg woven bags (with inner plastic lining) or 1-ton jumbo bags. Custom printing with customer logos or English labels is also supported.
Q
What are the storage requirements and shelf life of PAFC?
Liquid PAFC should be stored sealed in a cool, well-ventilated place at temperatures ≤ 30°C, away from direct sunlight and fire sources, with a shelf life of 12 months (sealed). Solid PAFC should be stored in a dry warehouse with humidity ≤ 60%, protected from moisture, stacked no more than 2 layers high, and has a shelf life of 24 months (unopened).
Q
Does PAFC meet safety and heavy metal content standards?
Yes. PAFC strictly controls heavy metal content to meet safety standards. The mass fractions are: As ≤ 0.0005%, Cr ≤ 0.005%, Hg ≤ 0.00002%, Pb ≤ 0.002%, and Cd ≤ 0.0002%, for both liquid and solid forms. These specifications ensure the product is safe for use in municipal drinking water pretreatment and industrial wastewater applications.
