3.Main Functions and Applications (What are its

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.
Used in drinking water treatment, featuring low residual iron, dense and compact flocs, and fast settling.
Used for decolorization, phosphorus removal and turbidity reduction in dyeing, papermaking, electroplating and chemical wastewater.
Used for municipal sewage and sludge treatment to reduce COD, suspended solids and total phosphorus.
Superior to conventional aluminum and iron salts - wide applicable pH range, larger and denser flocs, faster settling, and no risk of aluminum residue.

4.A Benchmark-Level Industrial Masterpiece - A Meticulously Crafted "Efficient Flocculation" Coagulant!

Total iron content >= 11.0% (premium grade per GB/T 14591).

Optimal basicity 8.0–16.0% ensures superior coagulation performance. Low reducing substance and insoluble matter for clean treatment.

Wide applicable pH range, fast settling and low residual iron.

"What you see is what you get" - every lot ships with a complete certificate of analysis.
