Polyferric sulfate (PFS)-Polyferric sulfate (PFS)--Shandong Sanfeng Group Co., Ltd.

Polyferric sulfate (PFS) is an inorganic polymer flocculating water purifying agent. It has extremely strong coagulation ability, a fast sedimentation rate, a wide applicable pH range, low corrosiveness, and excellent water purification effects. At the same time, it requires a small dosage, incurs low costs, and the treated water has good quality, is non-toxic, and does not cause aluminum pollution. Moreover, it has good effects in breaking oil, deodorizing, and decolorizing. Therefore, it is widely used in the purification treatment of urban sewage, industrial sewage, slaughterhouse sewage, printing and dyeing sewage, papermaking sewage, and oily sewage.

① It avoids environmental problems such as aluminum ion residues caused by aluminum - based flocculants. When choosing flocculants, considerations should be given to high efficiency, low consumption, safety, harmlessness, and no secondary pollution.

② It can be rapidly mixed with water in any proportion. In its aqueous solution, there are a large number of polymeric iron complex ions such as [Fe₂(OH)]³⁺ and [Fe(H₂O)]³⁺. These ions can adsorb onto the surfaces of colloidal particles and suspended solids, neutralize their surface charges, reduce their potential, and change the colloidal particles from mutual repulsion to mutual attraction, thus promoting the aggregation of colloidal particles.

③ It has strong flocculation ability, large flocs, a faster sedimentation rate than aluminum salts, and a high removal efficiency for SS, total phosphorus, COD, BOD, and color in water.

④ The water purification effect is excellent, the water quality is good, and it does not contain harmful substances such as aluminum, chlorine, and heavy metal ions. There is no transfer of iron ions in the aqueous phase, and it is non - toxic.

⑤ It has a wide applicable pH range of 4 - 11 for water bodies, with the optimal pH range being 6 - 9. After purification, the change range of the pH value and total alkalinity of the raw water is small.

⑥ It has a remarkable purification effect on slightly polluted, algae - containing, low - temperature and low - turbidity raw water, and an especially good purification effect on high - turbidity raw water.
