Polymeric Aluminium Ferric Chloride (PAFC) - Leading China Suppliers & Factory for Water Treatment Solutions
Core Performance
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 coagulant that combines the properties of both aluminum ions (Al³⁺) and iron ions (Fe³⁺). Unlike regular PAC which relies solely on aluminum, PAFC utilizes a synergistic dual-charge adsorption mechanism — achieving over 30% higher flocculation efficiency, faster settling velocities (≥ 25 m/h), and broader applicability across different water quality conditions.
Q
What pH range is PAFC effective in?
PAFC is effective across a wide pH range of 4–10, with an optimal working range of 6–9. This broad adaptability makes it suitable for treating over 90% of global water treatment scenarios, including high-turbidity, high-salinity, and high-organic-matter wastewater.
Q
What types of wastewater can PAFC treat?
PAFC is suitable for a wide range of wastewater types including municipal sewage (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 clarification), and food processing wastewater (starch/protein suspended solid removal).
Q
What are the available packaging options for PAFC?
PAFC is available in both liquid and solid forms. The liquid type comes in 200L plastic drums, 1000L IBC totes, or liquid bags. The solid type is packaged in 25kg woven bags (with inner plastic lining) or 1-ton jumbo bags. Custom branding and English labeling are available upon request.
Q
How should PAFC be stored to maintain its effectiveness?
Liquid PAFC should be stored in a sealed, cool, and well-ventilated environment at temperatures ≤ 30°C, away from direct sunlight and fire sources. Solid PAFC should be stored in a dry warehouse with humidity ≤ 60%, protected from moisture, and stacked no more than 2 layers high. Shelf life is 12 months for liquid (sealed) and 24 months for solid (unopened).
Q
Is PAFC safe for drinking water and food-related water treatment applications?
Yes. PAFC meets strict heavy metal content standards — including extremely low limits for arsenic (As ≤ 0.0005%), mercury (Hg ≤ 0.00002%), lead (Pb ≤ 0.002%), cadmium (Cd ≤ 0.0002%), and chromium (Cr ≤ 0.005%) — making it safe for use in municipal drinking water treatment and food processing wastewater applications.
