Polyferric sulfate(PFS) is an efficient and multifunctional inorganic polymer flocculant with a chemical formula of strong electrical neutralization ability and adsorption bridging effect. After hydrolysis, it generates a multi-core complex that can quickly remove colloids, suspended solids, and organic matter from water, with a sedimentation rate better than traditional aluminum salts. It is suitable for the treatment of municipal sewage and industrial wastewater (such as papermaking, printing and dyeing, electroplating), especially adept at phosphorus removal, decolorization, and removal of heavy metals . The pH is widely applicable, with less residual iron ions, dense and low sludge volume, reducing subsequent treatment costs. Moreover, its dosage is low, and the cost is lower than similar products. It has both coagulation and oxidation functions. PFS has become one of the key agents in modern water treatment due to its high efficiency, safety, and strong adaptability.
PFS core product features
Efficient flocculation and rapid sedimentation
·Strong electrical neutralization ability: PFS hydrolyzes to produce multi nuclear hydroxyl complexes , which can quickly neutralize the negative charges on the surface of colloidal particles and disrupt the stability of wastewater.
·Adsorption bridging effect: The polymer chain structure can adsorb suspended solids to form alum flowers, greatly reducing processing time.
Widely applicable, multifunctional purification
·Phosphorus and nitrogen removal: insoluble precipitate is generated with phosphate, with a phosphorus removal rate of>90%, suitable for municipal wastewater, aquaculture wastewater, etc.
·Heavy metal removal: Strong chelating ability for heavy metals such as lead (Pb
2+), chromium (Cr
6+ ),etc., with a removal rate of up to 95%~99%.
·Decolorization and COD reduction: Especially suitable for high chromaticity wastewater such as printing and dyeing, papermaking, etc., with a decolorization rate of ≥ 85% for reactive dyes and dispersed dyes.
Environmental protection and safety, sludge reduction
·Non toxic residue: PFS has no risk of aluminum ion residue and meets the GB 14591-2016 standard.
·Sludge compaction: The generated flocs have high compaction, reducing disposal costs.
Strong economy and low overall cost
·Low dosage: Under the same effect, the dosage is only 1/3 to 1/2 of ordinary iron salts.

Municipal sewage treatment
Applicable scenarios: domestic sewage, urban sewage treatment plants, rainwater treatment
Main function:
Phosphorus removal (TP): reacts with phosphate to form insoluble precipitate, with a total phosphorus removal rate of over 90%, meeting the Class A standard (TP ≤ 0.5mg/L) of the "Pollutant Discharge Standards for Urban Wastewater Treatment Plants" (GB 18918-2002).
Removing suspended solids (SS): Quickly settling colloids and organic particles in wastewater to reduce turbidity.
Sludge dewatering: The generated flocs are dense, reducing the volume of sludge and lowering the cost of subsequent pressure filtration or centrifugal dewatering.
papermaking wastewater
PFS function:
Discoloration: Decompose lignin and dye molecules, with a color removal rate of 80% to 90%.
COD reduction: Through oxidation and flocculation, the COD removal rate can reach 50%~70%.
Fiber recycling: promotes the coagulation of small fibers and improves pulp recovery rate.
Printing and dyeing/textile wastewater
Function of FS:
Discoloration: By chelating Fe3+ with dye molecules, the color removal rate is 85%~95
COD removal: Degradation of organic matter, reducing COD by 40% to 60%.
Heavy metal adsorption: It has an adsorption effect on metal ions such as copper (Cu) and chromium (Cr) that may exist in wastewater
Food/pharmaceutical wastewater
PFS function:
Remove colloidal organic matter such as protein, starch, and oil, with a COD removal rate of 50% to 70%.
Discoloration: Improving the turbidity of wastewater.
Non toxic residue: meets the requirements of food grade water treatment
Electroplating/metallurgical wastewater
PFS function:
Heavy metal precipitation: forms insoluble hydroxides or complexes with heavy metal ions, with a removal rate of>95%.
Breaking ability: It can break the complex state between cyanide and metal, and improve the removal rate of heavy metals.
Mining/beneficiation wastewater
PFS function:
Neutralizing acidic water: PFS itself is weakly acidic, but can be used in conjunction with lime to adjust pH.
Settling suspended mineral particles, such as coal slurry and tailings sand, with SS removal rate>90%.
Removal of heavy metals: Strong adsorption capacity for As, Cd, etc
Petroleum/chemical wastewater
PFS function:
Emulsification and oil removal: Combining with oil droplets to form flocs, achieving oil-water separation.
Reduce COD: Through oxidation and flocculation, the COD removal rate is 40%~60%.
Combined with advanced oxidation: It can be used in conjunction with ozone (O3) or Fenton to improve the removal rate of recalcitrant organic compounds.
Other special applications
River/lake management: algae removal, turbidity reduction, and improvement of black and odorous water bodies.
Garbage leachate treatment: removal of COD, heavy metals, and chromaticity.
Circulating cooling water: inhibits pipeline corrosion and reduces scaling.
