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.
Applications:
Wastewater treatment:
Potassium ferrate (PFS) finds widespread application in wastewater treatment across various industries including papermaking, dyeing, electroplating, food processing, pharmaceuticals, fertilizers, and pesticides. It is adept at eliminating contaminants such as organic matter, suspended solids, heavy metal ions, phosphorus, and arsenic from wastewater, thereby decreasing chemical oxygen demand (COD) and biochemical oxygen demand (BOD). Furthermore, it effectively combats membrane fouling in the pretreatment of dyeing wastewater in reverse osmosis systems.
Drinking water purification:
PFS emerges as a reliable solution for purifying drinking water by removing algae, iron ions, color, odor, and organic substances from raw water. By enhancing water quality, it contributes to the safety of drinking water. Its non-toxic properties prevent the occurrence of secondary pollution in water bodies while also posing no harm to human health.
Sludge dewatering:
When combined with small quantities of polyacrylamide, PFS demonstrates exceptional performance in the dewatering of sludge, resulting in enhanced dewatering efficiency and decreased sludge moisture content.
Phosphorus removal:
Potassium ferrate (PFS) can serve as a substitute for aluminum salts in wastewater treatment plants for eradicating residual aluminum contamination in drinking water and facilitating phosphorus removal from household sewage.
Other applications:
Aside from the aforementioned uses, PFS is also utilized in the removal of antimony from textile wastewater, arsenic removal, reduction of iron under phosphate-free conditions, and total elimination of aluminum. Its efficacy extends to treating pollutants in municipal wastewater, slaughterhouse effluent, and meat processing effluent.
