Can Ferric Chloride Replace Polyferric Sulfate

Ferric trichloride and poly-ferric sulfate can be used as water treatment agents. They are all iron systems, which generate trivalent iron ions after dissolution. The reaction between trivalent iron ions and water generates ferric hydroxide colloids with the differential effect of absorbing ferric trichloride and poly-ferric sulfate. This colloidal material has the effect of adsorbing and agglomerating suspensions in water, thus achieving the effect of water purification. What are the differences between them?

Ferric trichloride, as a water treatment agent, can be used as water-purifying flocculant in the water inlet industry. It can remove heavy metals, phosphorus, etc. contained in sewage with very good removal effect. Ferric trichloride is also a good decolorant. However, its properties belong to traditional iron salt, which has certain corrosiveness. After treatment, the water quality is easy to change into the color of iron, and will affect the color of water quality to a certain extent. In addition, iron chloride is an anhydrous product, so if exposed to the air for a certain time, it will absorb a certain amount of water in the air, which will also lead to the color change of iron chloride. Therefore, appropriate measures are required during storage and transportation.

Polyferric sulfate is an inorganic material which uses ferric trivalent ions to pass through a broad molecule of hydroxy polymerization with high aggregation. The hydrolyzed product also contains polynuclear complex and other products with flocculating effect. Compared with other inorganic flocculants, the flocculate has the characteristics of large particle size, fast settling speed, easy stratification and clarification, wide range of applicable pH, etc. It has good removal effect for suspended matter, organic matter, sulfide and heavy metal in water, and has the characteristics of decoloration, heavy metal removal Functions such as deodorization, demulsification and sludge dewatering, especially COD removal, are much superior to other water purification products. This product is non-toxic and corrosive, and will not cause secondary pollution after use. When polyferric sulfate is used to treat sewage, the removal rate of phosphorus reaches above 95, with obvious effect.
