Polyferric Sulfate (PFS), chemically represented as [Fe₂(OH)ₙ(SO₄)₃−n/₂]ₘ, is an inorganic polymeric coagulant widely used in water and wastewater treatment. It is synthesized through the polymerization of ferric sulfate (Fe₂(SO₄)₃) under controlled conditions, resulting in a high-molecular-weight compound with enhanced coagulation properties.
As a cost-effective and environmentally friendly alternative to traditional coagulants like aluminum sulfate (alum) or ferric chloride, PFS has gained prominence in industrial and municipal water treatment processes. Its unique structure, combining hydroxyl and sulfate groups with iron ions, enables efficient removal of contaminants through charge neutralization, adsorption, and flocculation mechanisms.
High Coagulation Efficiency
PFS demonstrates exceptional coagulation capabilities thanks to its highly charged polymeric species—such as [Fe₃(OH)₄]⁵⁺—that swiftly destabilize colloidal particles and organic substances in water.
Wide pH Adaptability
Unlike standard coagulants, PFS remains efficient over a wide pH range (4–10), reducing the necessity for pH adjustments in treatment systems.
Low Residual Iron Content
Compared to ferric chloride or alum, PFS produces denser and quicker-settling flocs, consequently minimizing residual iron levels in treated water.
Environmental Safety
Free from toxic components and devoid of harmful byproducts—such as aluminum residues associated with health concerns—PFS aligns with sustainable water treatment methodologies.
Cost-Effectiveness
Lower doses are needed when compared to traditional coagulants, resulting in reduced operational expenses.
Multifunctional Performance
Effective in the removal of 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.
