The efficacy of Polyferric Sulfate (PFS) in water treatment is directly linked to its precise manufacturing and stringent quality control. As a leading Polyferric Sulfate manufacturer in China, NINGBO INNO PHARMCHEM CO.,LTD. places immense importance on both aspects to ensure our clients receive a product that consistently delivers superior performance. This article provides an in-depth look at the production processes and quality assurance measures that define our commitment to excellence.

Manufacturing Polyferric Sulfate: A Complex Process

The synthesis of Polyferric Sulfate is a sophisticated chemical process that typically involves the oxidation, hydrolysis, and polymerization of ferrous sulfate in a highly acidic solution. While various methods exist, including catalytic oxidation and the use of different oxidizing agents (like hydrogen peroxide or sodium chlorate), the goal remains consistent: to create a stable, high-molecular-weight polymer with optimal coagulation properties.

Key stages in our manufacturing process include:

  • Raw Material Selection: We begin with high-purity ferrous sulfate and sulfuric acid to ensure the foundational quality of our PFS.
  • Controlled Oxidation: Precise control over the oxidation of ferrous ions (Fe2+) to ferric ions (Fe3+) is crucial. This step is carefully managed to achieve the desired iron valence state.
  • Hydrolysis and Polymerization: Under specific conditions of pH and temperature, ferric ions undergo hydrolysis and polymerization to form the characteristic long-chain PFS molecules. This stage is critical for developing the high charge density and polymeric structure that grants PFS its superior coagulating abilities.
  • Drying and Packaging: After synthesis, the liquid PFS is typically dried using advanced methods like spray drying to produce a stable, easily handleable powder. The final product is then packaged to maintain its integrity and prevent moisture absorption.

Rigorous Quality Assurance: Our Commitment to Excellence

At NINGBO INNO PHARMCHEM CO.,LTD., quality assurance is integrated into every step of the manufacturing process. We adhere to strict protocols to guarantee the purity, consistency, and effectiveness of our Polyferric Sulfate (CAS No. 10028-22-5).

  • Chemical Analysis: Each batch undergoes comprehensive chemical analysis to verify key parameters such as total iron content, Fe2+ levels, basicity, pH value, insoluble substances, and the absence of harmful heavy metals (like Cd, Hg, Cr, As, Pb). We meet or exceed industry standards for all these specifications.
  • Performance Testing: Beyond chemical purity, we conduct performance tests to ensure the coagulant and flocculating capabilities of our PFS meet expectations in simulated water treatment conditions.
  • Lot Traceability: Every batch is meticulously documented, allowing for complete traceability from raw materials to the finished product.
  • Certifications: We proudly hold certifications such as SGS and CIQ, underscoring our commitment to international quality standards.
