Polymeric Ferric Sulfate CAS 125622-39-3

2.Physical and Chemical Properties

• Appearance: Reddish-brown liquid; yellow to reddish-brown solid
• Solubility: Highly soluble in water
• Density: Approximately 1.45 g/cm³ (liquid, 20 °C)
• pH (1% aqueous solution): 2.0 – 3.0
• Stability: Stable; strongly acidic and corrosive

3.Main Functions and Applications (What are its uses?)

• Water treatment (core application): As an inorganic polymeric coagulant, PFS is widely used for the coagulation treatment of drinking water, industrial wastewater and municipal sewage. Through charge neutralization and adsorption bridging, it rapidly flocculates and removes suspended solids, colloids, COD, color and phosphorus.
• Drinking water purification: Used in drinking water treatment, featuring low residual iron, dense and compact flocs, and fast settling.
• Industrial wastewater: Used for decolorization, phosphorus removal and turbidity reduction in dyeing, papermaking, electroplating and chemical wastewater.
• Municipal sewage: Used for municipal sewage and sludge treatment to reduce COD, suspended solids and total phosphorus.
• Advantages: Superior to conventional aluminum and iron salts - wide applicable pH range, larger and denser flocs, faster settling, and no risk of aluminum residue.
