Under the background of environmental protection, the development space of polyferric sulfate (PFS) industry continues to expand

​​ ​​Polymeric ferric sulfate (PFS), also known as polyiron sulfate and polyiron, has the chemical formula [Fe2(OH)n(SO4)3-n/2]m. It is an inorganic polymer coagulant with superior performance. Polyferric sulfate appears as a light yellow amorphous powdery solid, easily soluble in water, slightly soluble in ethanol, and insoluble in ethyl acetate and acetone. Polymeric ferric sulfate has the advantages of moisture absorption, fast settling speed, safety and reliability, and strong adsorption capacity. It is widely used in the field of industrial wastewater treatment.

The main preparation methods of polyferric sulfate include potassium (sodium) chlorate oxidation, hydrogen peroxide oxidation, catalytic oxidation, nitric acid oxidation, etc. The hydrogen peroxide oxidation method refers to using hydrogen peroxide as the oxidant, sulfuric acid, water, and ferrous sulfate as raw materials, and heating to high temperature to obtain polymerized ferric sulfate. This method has the advantages of short production cycle, high stability, convenient operation, and high purity of the finished product, but the production The cost is high and not suitable for large-scale production. Catalytic oxidation method is widely used in the industrial production of polyferric sulfate.

The main raw materials of polymeric ferric sulfate are ferrous sulfate and sulfuric acid. Ferrous sulfate, also known as green vitriol, has the chemical formula FeSO4 and is reducible, easily oxidized, and easily weathered. Suzhou Runjier Environmental Protection New Materials Co., Ltd., CNNC Huayuan Titanium Dioxide Co., Ltd., and Longbai Group Co., Ltd. are the main manufacturers of ferrous sulfate in my country. As an important industrial raw material, sulfuric acid has strong market demand. According to data from the National Bureau of Statistics, my country’s sulfuric acid production will reach 85.56 million tons in 2021, a year-on-year increase of 2.7%. Sufficient supply of raw materials lays the foundation for the development of the polyferric sulfate industry.

According to the “2023-2027 Polyferric Sulfate (PFS) Industry In-depth Market Research and Investment Strategy Suggestions Report released by the Industrial Research Center It shows that the main application field of polymeric ferric sulfate is industrial wastewater treatment. Industrial wastewater refers to the wastewater and waste liquid produced during industrial production, which can easily cause environmental pollution and harm human health. According to data from the National Bureau of Statistics, my country’s total industrial wastewater discharge reached 75.85 billion tons in 2021. Polyferric sulfate can treat papermaking wastewater, printing and dyeing wastewater, and electroplating wastewater. It has the advantages of low cost, good water purification effect, and good coagulation performance.

There are many polyferric sulfate manufacturers in my country, and the market competition is fierce. Harbin Welding Institute Huatong (Changzhou) Welding Co., Ltd., Hubei Xinkang Pharmaceutical Chemical Co., Ltd., Shandong Zibo Tianshui New Materials Co., Ltd., Hunan Yide Chemical Co., Ltd., etc. are the main manufacturers of polyferric sulfate in my country.

Industry analysts said that polymeric ferric sulfate has excellent performance and is widely used in the field of industrial wastewater treatment. As the concept of environmental protection continues to deepen, polymerization The market demand for iron sulfate will continue to rise. After years of experience accumulation, my country’s polyferric sulfate production technology has matured and product quality has been continuously improved. Overall, my country’s polyferric sulfate industry still has considerable room for development.
