Yellow Powder Ferric Sulfate for Water Treatment

Product Description:

Polyferric Sulfate (PFS) , commonly referred to as polymeric ferric sulfate, is classified as an iron-based inorganic polymer coagulant. In its solid state, it appears as light yellow powder or granules, while its dissolved form results in a reddish-brown transparent solution.

This coagulant is characterized by its excellent water solubility and is denoted by the following chemical formula: [Fe2(OH)n(SO4)(6-n)/2]m , where n is less than 2 and m exceeds 10.

Here is a detailed summary of Polyferric sulfate (PFS):

Features:

High flocculation efficiency: PFS, as a polymer, possesses strong adsorption properties. Its fast flocculation formation rate results in large and dense flocs that settle quickly, enabling rapid water clarification. For instance, in wastewater treatment, it can significantly reduce the turbidity of water within a short period.

Wide pH adaptability: It is effective within a pH range of 4 to 11. Its adaptability to low-temperature, low-turbidity water and water with a pH between 5 and 9 is superior to that of low-molecular iron salts and aluminum salts, making it less affected by water temperature and pH fluctuations.

Strong charge neutralization ability: PFS contains high-positive-charge iron(III) ions and polymeric species such as Fe2(OH)3 3+, Fe2(OH)2 4+, and Fe3(OH)6 3+. These polymeric species enhance charge neutralization capabilities. The high cationic charge increases surface activity, enabling effective neutralization of suspended particles' charges, thereby forming larger aggregates for faster sedimentation.

High cost-effectiveness: Compared to traditional inorganic coagulants like aluminum salts and iron salts, PFS achieves better treatment results with lower dosage requirements. Its cost per ton of water treatment is 30%-60% lower than that of traditional aluminum salts, reducing treatment costs.

Good settling performance: The flocs formed after PFS reacts with water are large, dense, and settle quickly. The settled sludge exhibits good dewaterability, reducing sludge volume and facilitating subsequent sludge treatment.

Strong adaptability: It is effective for treating various types of water, including high-turbidity water, low-turbidity water, high-algal water, drinking water, and sewage.

Extended shelf life after dissolution: Unlike some coagulants that lose efficacy shortly after dissolving, PFS remains stable for extended periods in solution, allowing for better storage and use.

Self-indicating properties: Excessive dosage can be detected through its red color, which helps avoid waste and saves costs.

Applications:

PFS is extensively applied in the treatment of wastewater in various industries, including papermaking, dyeing, electroplating, food processing, pharmaceuticals, fertilizers, and pesticides. It plays a crucial role in effectively eliminating pollutants such as organic matter, suspended solids, heavy metal ions, phosphorus, and arsenic from wastewater. This results in a reduction of chemical oxygen demand (COD) and biochemical oxygen demand (BOD). Furthermore, PFS helps in mitigating membrane fouling during the pretreatment of dyeing wastewater in reverse osmosis systems.

PFS is instrumental in the purification of drinking water by removing algae, iron ions, color, odor, and organic matter present in raw water. This enhances the overall quality of water and ensures the safety of drinking water. Moreover, its non-toxic and harmless properties aid in preventing secondary pollution in water bodies and have no adverse effects on human health.

When used in conjunction with small doses of Polyacrylamide, PFS demonstrates exceptional performance in dewatering sludge. It enhances dewatering efficiency and reduces the moisture content of sludge effectively.

PFS can serve as a substitute for aluminum salts in wastewater treatment plants, aiding in the elimination of residual aluminum pollution from drinking water and facilitating the removal of phosphorus from domestic sewage.

Aside from the aforementioned uses, PFS finds applications in various other areas such as antimony removal from textile wastewater, arsenic removal, algae removal, iron reduction in phosphate-free conditions, and total aluminum removal. Its high efficiency in treating pollutants in municipal wastewater, slaughterhouse effluent, and meat processing effluent makes it a versatile solution in diverse environmental settings.
