Product Description:
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.
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.
