Polyferric sulfate (PFS) liquid type

Polyferric sulfate is a cationic inorganic polymeric flocculant with multiple hydroxyl and polynuclear complexes. PFS can be rapidly mixed with water at any ratio. It has a larger molecular weight than general inorganic mixed coagulants. When used as a water treatment agent, it has strong adsorption, flocculation bridging, and coagulation precipitation properties. In addition, it forms large and fast flocs, the flocs are not easily broken, and it has good re-coagulation properties. The settled water filters quickly, and it has advantages such as a wide range of water pH values.

    Product Performance

    1. High Efficiency: Polyferric sulfate is a composite polymer with a large molecular structure and strong adsorption capacity. Its water purification effect is superior to all traditional inorganic water treatment agents;
    2. Rapid: After being added to raw water, it forms large flocs, which settle quickly, have high activity, and good filterability;
    3. Strong Adaptability: It is highly adaptable to various raw waters and has minimal impact on the pH value of water (pH 4-11). Regardless of the raw water turbidity or the concentration of wastewater pollutants, its purification effect is significant;
    4. Low Dosage: It has low corrosiveness to equipment and pipelines, is easy to operate, requires a small dosage, and has low and controllable purification costs. It is inherently red, so excessive dosage can be visually perceived, reducing waste.

    Packaging Method

    Tank truck transportation; storage requires the use of tons of barrels and corrosion-resistant storage tanks.

    Usage Method

    Liquid products need to be dissolved and diluted before use. Users can adjust the concentration of the agent through experiments based on different water qualities to determine the optimal dosage. The specific dosage should be based on flocculation tests and experiments.
