Product Dosage:

Product function:

Polyferric sulfate (PFS) is an inorganic polymer flocculant formed by inserting hydroxyl groups into the network structure of iron sulfate molecules. It can effectively remove suspended solids, organic matter, sulfides, nitrites, colloids, and metal ions from water. Polymeric sulfuric acid has functions such as deodorization, demulsification, and sludge dewatering, and also has a good removal effect on planktonic microorganisms. The effect of PFS in treating oily wastewater is much more significant than that of ferrous sulfate, and it has less corrosiveness to metal equipment, but it produces more sludge and the effluent is colored.

Product application:

1. Water treatment field

The application of polymeric ferric sulfate in the field of water treatment is the most extensive. It can be used for the treatment of industrial wastewater, domestic sewage, and drinking water. Through the coagulation effect of polymeric ferric sulfate, harmful substances such as suspended solids, organic matter, and heavy metal ions in water can be effectively removed, achieving the goal of purifying water quality. When using polymeric ferric sulfate for water treatment, attention should be paid to controlling the dosage and making appropriate adjustments according to different water quality conditions.

2. In the field of agriculture

Polymeric ferric sulfate also has a wide range of applications in the agricultural field. It can be used for irrigation water treatment, preventing the growth of algae and microorganisms, and promoting crop growth. In addition, polymeric ferric sulfate can also be used for soil improvement, by improving soil structure, increasing soil organic matter content, and enhancing soil fertility. When using polymeric ferric sulfate for agricultural applications, appropriate adjustments need to be made according to different soil and crop conditions.

3. Environmental protection field

Polymeric iron sulfate also plays an important role in the field of environmental protection. It can be used for air purification, flue gas desulfurization, waste gas treatment, etc. Through the adsorption and catalytic action of polymeric ferric sulfate, harmful substances in air and exhaust gas can be effectively removed, achieving the goal of purifying the environment. When using polymeric ferric sulfate for environmental applications, appropriate adjustments need to be made according to different environmental and pollutant conditions.

4. Chemical industry field

Polymeric ferric sulfate also has certain applications in the chemical industry. It can be used for catalyst preparation, dye synthesis, oil refining, etc. By catalyzing the polymerization of ferric sulfate, the rate and selectivity of chemical reactions can be increased, achieving the goal of optimizing production processes and improving product quality. When using polymeric ferric sulfate for chemical applications, appropriate adjustments need to be made according to different reactions and product conditions.

Product usage instructions:

1. Determination of usage amount: Before using polymeric ferric sulfate, it is necessary to conduct laboratory tests or on-site direct machine tests before determining the usage amount. Firstly, dissolve the polymerized ferric sulfate into a 3% solution, take a certain amount of wastewater, add it dropwise, and observe the changes in water. If the alum flowers settle quickly and the water quality is clear after shaking evenly, it indicates that the dosage is appropriate.

2. After determining the dosage, establish operating procedures, such as dissolving the medication in clean water to a 3-5% solution before use, and then determining how to measure and mix it.

3. The operator first familiarizes themselves with the MSDS of polymeric ferric sulfate, and then proceeds with step-by-step operations according to the operating procedures.

4. Note: The medicine must be mixed evenly and used on the same day of preparation, especially in summer or winter, to avoid deterioration or freezing. During the configuration process, slight sedimentation is normal.
