Water Treatment PolyFerric Sulfate for Industrial Use

Product Description:

Polyferric sulfate (PFS), commonly known as polymeric ferric sulfate, belongs to the category of iron-based inorganic polymer coagulants. In its solid state, PFS appears as light yellow powder or granules, while its liquid form manifests as a reddish-brown transparent solution when dissolved in water. This coagulant exhibits high water solubility and is characterized by the chemical formula [Fe2(OH)n(SO4)(6-n)/2]m, where n is less than 2 and m is greater than 10.

Here is a more detailed overview of PFS:

• Name: Polyferric sulfate (PFS)
• Common Name: Polymeric ferric sulfate
• Physical Form: Light yellow powder or granules (solid), Reddish-brown transparent solution (liquid)
• Chemical Formula: [Fe2(OH)n(SO4)(6-n)/2]m (where n < 2 and m > 10)
• Solubility: Highly water-soluble

Features:

High flocculation efficiency: Polymerized Ferric Sulfate (PFS) demonstrates exceptional adsorption properties, leading to rapid flocculation formation and the creation of large, dense flocs that settle swiftly. This results in rapid water clarification, exemplified in wastewater treatment by the significant reduction of water turbidity in a short timeframe.

Wide pH adaptability: PFS is efficient across a pH range of 4 to 11. It surpasses low-molecular iron salts and aluminum salts in its adaptability to low-temperature, low-turbidity water, as well as water with a pH between 5 and 9. Its performance remains unaffected by water temperature and pH fluctuations.

Strong charge neutralization ability: Featuring high-positive-charge iron(III) ions and polymeric species like Fe ₂ (OH) ₃ ³⁺ , Fe ₂ (OH) ₂ ⁴⁺ , and Fe ₃ (OH) ₆ ³⁺ , PFS enhances charge neutralization capabilities. The elevated cationic charge boosts surface activity, facilitating efficient neutralization of suspended particles' charges, thus forming larger aggregates for quicker sedimentation.

High cost-effectiveness: Compared to traditional inorganic coagulants such as aluminum salts and iron salts, PFS achieves superior treatment outcomes with lower dosage requirements. Its cost per ton of water treatment stands 30%-60% lower than that of traditional aluminum salts, leading to reduced treatment expenses.

Good settling performance: Following the reaction of PFS with water, the resulting flocs are sizable, compact, and settle rapidly. The settled sludge displays favorable dewaterability, decreasing sludge volume and streamlining subsequent sludge treatment processes.

Strong adaptability: PFS proves effective in the treatment of diverse water types, encompassing high-turbidity water, low-turbidity water, high-algal water, drinking water, and sewage.

Extended shelf life after dissolution: Unlike certain coagulants that lose efficacy shortly after dissolving, PFS remains stable in solution for extended durations, enabling better storage and utilization.

Self-indicating properties: Excessive dosage of PFS can be easily identified by its red coloration, assisting in the prevention of wastage and cost savings.
