Description
Poly Ferric Sulfate (PFS) is a high-performance inorganic polymer coagulant, primarily used in water and wastewater treatment. It is produced by polymerizing ferric sulfate under controlled conditions, resulting in a compound with superior coagulation, adsorption, and precipitation capabilities. PFS forms strong, dense flocs and is particularly effective at removing suspended solids, turbidity, phosphate, heavy metals, and COD/BOD. Compared to traditional coagulants like ferric sulfate or aluminum sulfate, PFS offers faster settling, reduced sludge volume, and better performance across varying water qualities.
Specifications
| Grade Type | Description | Typical Fe Content (%) |
|---|---|---|
| Water Treatment Grade | Standard for industrial and municipal use | 19%–21% (liquid); ≥20% (solid) |
| Drinking Water Grade | High-purity, low heavy metal content for potable water | ≥20% |
| Low-pH Grade | Suitable for low-alkalinity or acidic raw water | ≥19% |
| Customized Grade | Tailored basicity, color, or iron content as required | As requested |
Applications
- Municipal Water Treatment: Used for turbidity, color, and pathogen reduction in drinking water.
- Wastewater Treatment: Efficient in removing suspended solids, phosphorus, heavy metals, and organics.
- Papermaking Industry: Enhances retention and improves water clarity in white water systems.
- Oil & Gas Industry: Aids in drilling wastewater and oilfield effluent clarification.
- Mining & Metallurgy: Applied in tailing pond treatment and metal-containing wastewater treatment.
Advantages
- Rapid floc formation and fast sedimentation
