As a leading choice among China suppliers and factory manufacturers, this polymer composite ensures superior performance in water purification applications

Product Details

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:

🔬 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

What is PAFC and how does it differ from 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 a dual-charge adsorption mechanism — Al³⁺ neutralizes negatively charged colloids while Fe³⁺ captures fine particles through net capture. This synergy improves flocculation efficiency by over 30% compared to single-component flocculants.

What pH range is PAFC effective in?

PAFC is effective across a broad pH range of 4–10, with optimal performance between pH 6–9. This wide adaptability makes it suitable for treating high turbidity water (≤10,000 NTU), high-salinity water (such as seawater desalination pretreatment), and high organic matter wastewater (such as printing and dyeing or paper mill effluent), covering over 90% of global water treatment scenarios.

What industries and wastewater types is PAFC suitable for?

PAFC is widely used across municipal and industrial sectors, including: municipal sewage treatment (SS reduction, partial COD removal), printing and dyeing wastewater (decolorization, organic matter removal), electroplating and chemical wastewater (heavy metal removal such as Cr⁶⁺ and Cu²⁺), paper mill and mining wastewater (white water recovery, coal slurry clarification), and food processing wastewater (starch/protein suspended solids removal).

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 (lined with plastic inner bags) or 1-ton jumbo bags. Custom branding with customer logos or English labels is also available for bulk packaging orders.

What are the storage requirements and shelf life for PAFC?

Liquid PAFC should be stored sealed in a cool, well-ventilated location at temperatures ≤ 30°C, away from direct sunlight and heat sources — shelf life is 12 months (sealed). Solid PAFC must be kept in a dry warehouse with humidity ≤ 60%, protected from moisture, and stacked no more than 2 layers high — shelf life is 24 months (unopened).

What are the key technical specifications of PAFC?

Key specifications include: Al₂O₃ content ≥ 8.0% (liquid) / ≥ 28.0% (solid); Fe mass fraction 1.5–5.0%; basicity 20–85%; pH of 10g/L aqueous 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 international water treatment safety standards.
