Polymeric Aluminium Ferric Chloride (PAFC) - China Suppliers & Factory for Effective 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.

Applicable Scenarios
PAFC, with its "all-round" characteristics, is widely used in global municipal, industrial, and special water treatment scenarios:
- Municipal sewage: Reduce SS, remove part of COD
- Printing and dyeing wastewater: Decolorization, removal of organic matter
- Electroplating / Chemical Wastewater: Removal of Heavy Metals (Cr⁶⁺, Cu²⁺) and Complexing Agents
- Paper mill / mining wastewater: White water recovery, coal slurry water clarification
- Food processing wastewater: Removal of starch/protein suspended solids
