China Polymeric Aluminium Ferric Chloride (PAFC) - Premium Water Treatment Solution from China Suppliers and Factory Supplier, Factory
This innovative product is an inorganic polymer composite designed to optimize water treatment processes. Formulated with polyaluminum chloride and complexed with polymeric iron, it enhances the molecular structure for superior electro-neutralization, bridging adsorption, and sedimentation capabilities. Ideal for addressing source water with high levels of organic pollution, this product effectively manages both low and high turbidity conditions, even in cold temperatures. As a leading supplier in China, our factory is dedicated to providing high-quality water treatment solutions to meet 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 aluminum ions (Al³⁺) and iron ions (Fe³⁺). Unlike standard PAC which relies solely on aluminum, PAFC benefits from the synergistic effect of both ions — Al³⁺ handles electrical neutralization while Fe³⁺ enhances net capture of fine particles. This dual-action mechanism improves flocculation efficiency by over 30% compared to single-component flocculants.
Q
What pH range is suitable for PAFC application?
PAFC has a wide applicable pH range of 4–10, with optimal performance between pH 6–9. This broad adaptability makes it effective across diverse water treatment scenarios, including high turbidity (≤10,000 NTU), high salinity environments such as seawater desalination pretreatment, and high organic matter wastewater such as printing, dyeing, and paper mill effluents.
Q
What industries can benefit from using PAFC?
PAFC is suitable for a wide range of industries and applications, including municipal sewage treatment (SS and COD reduction), printing and dyeing wastewater (decolorization and organic removal), electroplating and chemical wastewater (heavy metal removal), paper mill and mining wastewater (white water recovery and coal slurry clarification), and food processing wastewater (starch and protein suspended solids removal). It covers over 90% of global water treatment scenarios.
Q
What packaging options are available for PAFC, and can custom labeling be arranged?
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 comes in 25kg woven bags (with inner plastic lining) or 1-ton jumbo bags. Custom branding, including customer logos and English labels, can be printed on the jumbo bags upon request.
Q
What are the storage requirements and shelf life of PAFC?
Liquid PAFC should be stored in a sealed container in a cool, well-ventilated location (temperature ≤ 30°C), away from direct sunlight and ignition sources. Its shelf life is 12 months when sealed. Solid PAFC must be stored in a dry warehouse with humidity ≤ 60%, protected from moisture and physical damage, and stacked no more than 2 layers high. Unopened solid PAFC has a shelf life of 24 months.
Q
Is PAFC safe for drinking water treatment and does it meet heavy metal standards?
Yes, PAFC is formulated to meet strict safety standards for water treatment applications. Its heavy metal content is tightly controlled — for example, As ≤ 0.0005%, Pb ≤ 0.002%, Hg ≤ 0.00002%, Cr ≤ 0.005%, and Cd ≤ 0.0002%. These values comply with standard water treatment chemical safety requirements, making PAFC suitable for use in both industrial wastewater treatment and municipal water purification processes.
