In the critical field of water treatment, selecting the appropriate coagulant is paramount for achieving effective purification and meeting environmental standards. Two commonly discussed iron-based coagulants are Ferric Sulfate and Polyferric Sulfate (PFS). While both contain trivalent iron ions, their molecular structures and resulting properties lead to significant differences in performance, especially in wastewater treatment. As NINGBO INNO PHARMCHEM CO.,LTD., we aim to provide clarity on these distinctions to help you make informed purchasing decisions.

Understanding the Basics: Ferric Sulfate vs. Polyferric Sulfate

Ferric sulfate, with a lower molecular weight and a simpler inorganic structure, has traditionally found uses in medicine and industrial fertilizers. While it can be used in water treatment, its effectiveness in removing suspended solids and complex pollutants is often limited compared to its polymeric counterpart.

Polyferric Sulfate, on the other hand, is a high-molecular-weight polymer. Its unique macromolecular structure allows it to form long, chain-like colloids upon hydrolysis. These long chains possess strong adsorption forces and an effective net-trapping effect, making them significantly more efficient at capturing and settling out impurities from wastewater. This enhanced capability makes PFS the preferred choice for many industrial applications.

Physicochemical Property Differences

The differences extend to their physical properties. Ferric sulfate typically appears as a grayish-white powder with a melting point around 175°C. In contrast, Polyferric Sulfate is often a yellow or reddish-brown amorphous powder or granular solid, with a higher melting point of approximately 190°C and a higher relative density. These variations in density, pH value, and total iron content underscore their distinct chemical behaviors.

Performance in Water Treatment

The primary advantage of Polyferric Sulfate lies in its superior coagulation effect across various types of wastewater. Its strong adsorption and sedimentation capabilities are particularly beneficial for removing suspended solids (SS), chemical oxygen demand (COD), and improving phosphorus and sulfur removal. For industrial sectors seeking reliable wastewater treatment solutions, our Polyferric Sulfate offers demonstrably better results than traditional ferric sulfate.
