Polymer Ferric Sulphate (PFS) is a high-performance inorganic polymer coagulant widely used in water and wastewater treatment. Known for its strong flocculation ability, fast sedimentation, and broad pH adaptability, PFS has become a preferred alternative to traditional coagulants such as alum and ferric chloride. This article provides a comprehensive overview of Polymer Ferric Sulphate, including its chemical properties, working mechanism, key applications, advantages, comparison with other coagulants, and practical usage guidelines.
Polymer Ferric Sulphate, commonly abbreviated as PFS, is an inorganic polymer coagulant synthesized through controlled hydrolysis and polymerization of ferric sulfate. It is primarily used for removing suspended solids, organic matter, heavy metals, and phosphorus from water.
Unlike traditional iron salts, Polymer Ferric Sulphate forms stable polymer chains with high positive charge density, making it extremely effective in destabilizing colloidal particles in water.
Polymer Ferric Sulphate consists mainly of polymerized ferric ions (Fe³⁺) combined with sulfate groups. Its molecular structure enables strong adsorption and bridging effects during coagulation.
| Property | Description |
|---|---|
| Appearance | Reddish-brown liquid or yellow powder |
| Fe³⁺ Content | ≥ 19% |
| pH Range | 4–11 |
| Solubility | Completely soluble in water |
| Stability | High stability, low corrosiveness |
The coagulation mechanism of Polymer Ferric Sulphate involves several synergistic processes:
These mechanisms allow PFS to form large, dense flocs that settle rapidly, improving clarification efficiency even under low temperatures or high turbidity conditions.
Polymer Ferric Sulphate is widely used across multiple industries due to its versatility and efficiency.

Compared with conventional coagulants, Polymer Ferric Sulphate offers significant advantages:
| Coagulant | Efficiency | Sludge Volume | pH Sensitivity |
|---|---|---|---|
| Polymer Ferric Sulphate | Very High | Low | Low |
| Ferric Chloride | Medium | High | High |
| Aluminum Sulfate (Alum) | Medium | High | High |
Recommended dosage typically ranges from 20–100 mg/L, depending on water quality. Jar testing is advised for optimal results.
