⏹︎ Product Features
Poly Ferric Chloride (PFC) is an acidic polymeric compound with the molecular formula [Fe₂(OH)ₙ(CLn)₃–N/2]ₘ, where n > 2 and m = f(n). In aqueous solutions, it contains a large number of polymeric iron complex ions such as [Fe₂(OH)₃]³⁺, [Fe(H₂O)₆]³⁺, and [Fe₃(OH)₃]⁶⁺. It is a coagulant that easily forms colloids and exhibits excellent coagulation performance. Its molecular structure consists of three-dimensional polymerized multinuclear complex ions.
PFC hydrolyzes rapidly in water, generating highly efficient multinuclear hydroxy iron complex cations, such as Fe[Fe(OH)₂]ₙ^(3+n)⁺. During raw water purification, it effectively neutralizes the surface charge of suspended particles and bridges the particles to enhance floc formation.
-
High Coagulation Efficiency
Contains multivalent iron ions that rapidly form flocs, effectively removing suspended solids, colloids, heavy metals, and other impurities from water.
-
Wide Applicable pH Range
Effective across a wide pH range (approximately 4–11), with optimal performance under acidic to mildly alkaline conditions.
-
Strong Decolorization and Phosphorus Removal Capability
It shows excellent performance in decolorizing and removing phosphorus from dyeing wastewater, industrial effluent, and domestic sewage.
-
Relatively High Corrosiveness
Due to the presence of free acids, corrosion resistance is required for storage and handling equipment.
-
Fast Settling and Low Sludge Volume
The dense flocs settle quickly, reducing the cost and volume of sludge treatment.
-
Good Solubility and Easy to Use
Available in liquid or powder form, it dissolves quickly and does not easily clog equipment.
⏹︎ Applications
-
Demulsifier for Waste Emulsions, Emulsified Liquids, and Oily Wastewater
Used to break emulsions and separate oil from water in waste emulsions, emulsified wastewater, and oily wastewater.
-
Drinking Water Treatment
Removes turbidity, color, iron, manganese, algae, and other impurities to improve water clarity and stability.
- Sludge Dewatering and Solid-Liquid Separation in Biological (Thickened) Sludge
Helps with sludge dewatering, increases the solid content of sludge cakes, and reduces the cost of downstream sludge treatment.
-
Municipal Wastewater Treatment
Used for phosphorus and organic matter removal in domestic sewage, effectively reducing COD and BOD levels.
-
Industrial Wastewater Treatment
Widely applied in coagulation, sedimentation, and decolorization processes for wastewater from industries such as papermaking, dyeing, slaughterhouses, breweries, chemical plants, steel, and coal industries.
-
Environmental Engineering
Used in projects such as river remediation and the treatment of eutrophic lakes.
