I. Introduction
Polymeric Ferric Sulfate (PFS), as a highly efficient inorganic polymer coagulant, is widely used in the field of water treatment. This paper aims to introduce the production process of polyferric sulfate in detail, including raw materials and ingredients preparation, reaction process and condition control, product separation and purification, crystallization and drying, product packaging and storage, quality testing and standards, production safety and environmental protection measures, process optimization and cost control.
Second, raw materials and ingredients preparation
1. Main materials: Industrial grade ferrous sulfate (FeSO₄), Oxidizer (e. g. Hydrogen peroxide H₂O₂, sodium hypochlorite NaClO, etc.), sulfuric acid (H₂SO₄).
2. Preparation of ingredients: accurately weigh various raw materials according to the formula requirements to ensure that the purity and quality of raw materials meet the production requirements.
Third, reaction process and condition control
1. Reaction principle: ferrous sulfate is oxidized to polyferric sulfate under the action of oxidizing agent.
2. Reaction conditions: Control reaction temperature, pH value, reaction time and dosage of oxidizer to ensure smooth reaction.
3. Mixing and mixing: The appropriate mixing method is used to ensure that the raw materials are mixed evenly and the reaction is sufficient.
Fourth, product separation and purification
1. Precipitation and filtration: After the end of the reaction, insoluble impurities are removed by precipitation and filtration operations.
2. Ion exchange or adsorption: The use of ion exchange resin or activated carbon and other materials to further remove ionic impurities in the solution.
Crystallization and drying of polyferric sulfate
1. Crystallization: Through the control of temperature, concentration and other conditions, the crystallization of polyferric sulfate.
2. Drying: The crystallized polyferric sulfate is dried to remove excess water.
6. Product packaging and storage
1. Packaging: Put the dried polyferric sulfate into a special bag or container to ensure that the product is not contaminated.
2. Storage: Store the product in a dry, cool and ventilated warehouse, away from direct sunlight and high temperature.
7. Quality testing and standards
1. Detection indicators: including appearance, iron content, basicity, pH value, insoluble content, etc.
2. Testing method: Testing according to national standards or industry standards.
3. Quality standards: Ensure that the product indicators meet the relevant standards to ensure product quality.
8. Production safety and environmental protection measures
1. Safety measures: strictly abide by safety production rules and regulations to ensure the normal operation of equipment; Operators should wear protective equipment to prevent chemical corrosion and injury.
2. Environmental protection measures: the use of advanced wastewater treatment equipment to ensure that wastewater discharge standards; The exhaust gas generated is discharged after treatment to reduce the impact on the environment.
9. Process optimization and cost control
1. Process optimization: Optimize the production process and improve production efficiency through continuous research and experiments; Improve equipment and technology to reduce energy and material consumption.
2. Cost control: strengthen raw material procurement management to reduce procurement costs; Reasonable arrangement of production plan, reduce production cost; Improve product quality and added value, and enhance market competitiveness.
10. Conclusion
The production process of polyferric sulfate and its related contents are introduced in detail in this paper. Through strict production management and quality control measures, the quality and stability of polyferric sulfate products can be ensured. At the same time, optimizing the production process and strengthening the cost control is an important way to improve the competitiveness of enterprises.
