Product Description:
Polyferric Sulfate (PFS) , represented chemically as [Fe₂(OH)ₙ(SO₄)₃−n/₂]ₘ , is a type of inorganic polymeric coagulant that finds extensive use in water and wastewater treatment applications. The synthesis of PFS involves the controlled polymerization of ferric sulfate (Fe₂(SO₄)₃) under specific conditions, resulting in the formation of a high-molecular-weight compound with superior coagulation properties.
PFS has emerged as a popular choice in both industrial and municipal water treatment sectors due to its cost-effectiveness and environmentally friendly nature, serving as a viable substitute for traditional coagulants such as aluminum sulfate (alum) or ferric chloride. Its distinctive molecular structure, which incorporates hydroxyl and sulfate groups along with iron ions, enables efficient elimination of contaminants via mechanisms like charge neutralization, adsorption, and flocculation.
Features:
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.
Applications:
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.
