Ferric Polychloride

An inorganic polymer coagulant, which is produced from iron salts through hydrolysis, polymerization, and other reactions, widely used in water treatment, sewage treatment, and other fields.

1. Main Characteristics

- Hydrolysis generates various high-valent polymeric cations that can neutralize the negative charges of colloidal particles in water, forming flocculent precipitates (flocs), and rapidly adsorb suspended solids and colloids.

- Capable of removing phosphorus, heavy metals (such as arsenic, lead), organic matter, and color from water, with significant removal effects on COD and BOD.

2. Application Fields

2.1. Sewage Treatment:

- Industrial Wastewater: Treating electroplating, printing, dyeing, and papermaking wastewater (e.g., decolorization, heavy metal removal).

- Municipal Sewage: Phosphorus removal and turbidity reduction.

2.2. Drinking Water Purification:

- When meeting standards, it can be used as a coagulant for drinking water, but residual iron content must be controlled (≤0.3 mg/L).

2.3. Sludge Dewatering:

- Used as a conditioning agent to improve the filterability of sludge.
