1. Property & Specification
    Name: Solid Polymer Ferric Sulphate (SPFS)
    Molecular formula:  [Fe₂(OH)_n(SO₄)_3-n/2]m
    Appearance: Light yellow amorphous powder, hygroscopic, readily soluble in  water. 10%(W/W)aqueous solution is a transparent orange solution.

2. Use:
    As flocculant in purification of municipal water, industrial water, waste water, domestic sewage and sludge dewatering.

3. Features: (compared with other inorganic flocculant)
    1. High-efficiency inorganic polymer flocculant.
    2. Good coagulating property. Flocs formed are large and easily settable.
    3. SPFS is non-toxic. It can capture aluminum, chloride and heavy metal, and will not cause Fe contamination.
    4. Good effect in decolorizing, capturing oil, bacteria, algae, reducing COD, BOD and heavy metal.
    5. Low corrosion. Working pH range 4-11, with best performance at pH 6-9. pH and basicity of water almost do not change after treatment with SPFS.
    6. Suitable for purification of low-turbidity, low-algae, low-temperature, low-contaminated raw water. Particularly effective for high-turbidity raw water.
    7. Low dosage required, save 20%-50% of cost.

4. Package
    Plastic woven bag with PE liner. n.w. 25kg.
