The content detection of Polyferric Sulfate usually refers to the measurement of the content of its main component - iron ion. As polyferric sulfate is a complex inorganic polymer compound, its detection methods are diverse, covering chemical analysis and instrumental analysis.

The following are 15 core indicators commonly used in sewage treatment and their function descriptions, covering key parameters such as organic matter, nutrients, physical properties and microorganisms:

According to the existing technical documents and production process practice, the production process of polyaluminum ferric chloride (PAFC) is summarized as follows:

I. Mainstream production process classification

1. Acid dissolution one-step method

• Raw materials: aluminum ash, aluminum slag, bauxite, iron ore and other aluminum iron minerals
• process sequence:
• ① Raw material crushed to 40-60 mesh → ② mixed with hydrochloric acid/sulfuric acid (conditions: 80-100℃,3-5 atmospheres) → ③ added high alumina ash to adjust polymerization → ④ precipitation separation → ⑤ liquid or solid product (spray/drum drying)
• Features: low cost, fast reaction, but heavy metal impurities need to be strictly controlled

As an important inorganic polymer flocculant, polyferric sulfate has been widely used in the field of Water Treatment because of its advantages such as good flocculation effect, fast settling speed and wide application range.
