Product Positioning

This product is an inorganic polymer composite polymer, which is based on polyaluminum chloride and complexed with polymeric iron, increasing the molecular structure, enhancing the electro-neutralization, bridging adsorption, and sedimentation performance, and is an ideal agent for treating source water with severe organic pollution as well as source water with low temperature and low turbidity or low temperature and high turbidity.

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
