PAFC—-polyaluminium ferric chloride
Today let’s talk about the new wastewater treatment chemical: PAFC. It’s full name is polyaluminium ferric chloride, an inorganic polymer coagulant, used in water treatment and purification.

Composition and Structure
PAFC is a composite of aluminum and iron salts, combining the advantages of both, improving coagulation performance through synergistic synergy. Its molecular formula is [Al₂(OH)ₙCl₆-ₙLₘ], where m represents the degree of polymerization and n represents the neutrality of the product.
Key Features
Highly Efficient Coagulation: It exhibits a high degree of electrical neutralization and bridging effects on colloids and particulates in water, effectively removing micro-toxic substances and heavy metal ions.
Wide Application: It is particularly suitable for treating high-turbidity water and low-temperature, low-turbidity water, without the need for additional alkaline additives or coagulants.
Safety: As an inorganic polymer, it is non-toxic and non-polluting, meeting environmental requirements.
Application Scenarios
Mainly used for drinking water purification, industrial wastewater (such as printing and dyeing wastewater and oily wastewater), municipal sewage, and special water treatment (such as removing pollutants such as cadmium and fluoride).
