Polyferric Sulfate (PFS), with the chemical formula [Fe₂(OH)ₙ(SO₄)₃−n/₂]ₘ, serves as an inorganic polymeric coagulant widely utilized in water and wastewater treatment processes. It is produced by polymerizing ferric sulfate (Fe₂(SO₄)₃) under controlled conditions to create a high-molecular-weight compound known for its superior coagulation properties.
As an economical and environmentally friendly alternative to traditional coagulants such as aluminum sulfate (alum) or ferric chloride, PFS has become increasingly popular in both industrial and municipal water treatment applications.
The distinctive structure of PFS, combining hydroxyl and sulfate groups with iron ions, allows for efficient elimination of contaminants through mechanisms like charge neutralization, adsorption, and flocculation.
High Coagulation Efficiency
PFS exhibits superior coagulation performance due to its highly charged polymeric species (e.g., [Fe₃(OH)₄]⁵⁺), which rapidly destabilize colloidal particles and organic matter in water.
Wide pH Adaptability
Unlike conventional coagulants, PFS maintains effectiveness across a broad pH range (4–10), reducing the need for pH adjustment in treatment systems.
Low Residual Iron Content
PFS generates denser and faster-settling flocs compared to ferric chloride or alum, minimizing residual iron concentrations in treated water.
Environmental Safety
Non-toxic and free from harmful byproducts (e.g., aluminum residues linked to health concerns), PFS aligns with sustainable water treatment practices.
Cost-Effectiveness
Lower dosages are required compared to traditional coagulants, reducing operational costs.
Multifunctional Performance
Effective in removing turbidity, organic matter, phosphorus, heavy metals, and colorants.
Drinking Water Treatment
Removes suspended solids, algae, and organic contaminants to meet potable water standards.
Reduces disinfection byproduct precursors (e.g., trihalomethanes).
Industrial Wastewater Treatment
Textile/Printing Wastewater: Eliminates dyes and COD (Chemical Oxygen Demand).
Electroplating/Mining Wastewater: Precipitates heavy metals (e.g., Pb²⁺, Cu²⁺, Cr⁶⁺).
Paper/Pulp Wastewater: Controls lignin and colloidal impurities.
Municipal Sewage Treatment
Enhances sludge dewatering and reduces sludge volume.
Efficiently removes phosphorus to prevent eutrophication.
Stormwater and Agricultural Runoff Management
Treats non-point source pollution by adsorbing pesticides and nutrients.
Oil-Water Separation
Breaks oil emulsions in petrochemical or food processing effluents.
Advanced Treatment Processes
Used as a coagulant aid in membrane filtration or electrocoagulation systems.
