In the realm of water treatment, selecting the right coagulant is paramount for achieving efficient and cost-effective purification. NINGBO INNO PHARMCHEM CO.,LTD. often highlights the advantages of Polymeric Ferrous Sulfate (PFS) over traditional coagulants, such as ferric sulfate. Understanding these differences is key to optimizing water treatment processes.

While both Polymeric Ferrous Sulfate and Ferric Sulfate contain trivalent iron ions, their structures and functionalities differ significantly. Ferric sulfate is a low-molecular inorganic compound, whereas PFS is a macromolecule polymer. This structural difference dictates their performance in water treatment. PFS, as a high polymer, produces long chain-like colloids upon hydrolysis. These chains possess strong adsorption capabilities and a more pronounced sedimentation and trapping effect, making them superior for removing suspended particles and impurities.

The physicochemical properties also set PFS apart. While ferric sulfate might appear as a grayish-white powder or crystalline form, PFS is typically a yellow or reddish-brown amorphous powder or granular solid. More importantly, PFS demonstrates superior performance in various aspects of water treatment, including purification, precipitation, and sludge dewatering. Its ability to form larger, denser flocs leads to faster settling times, which is critical for efficient solid-liquid separation.

When considering operational parameters, PFS offers a wider pH range of applicability, typically from 4 to 11, compared to some traditional coagulants that may require more precise pH control. This broad applicability simplifies treatment processes and can reduce the need for extensive pH adjustment chemicals. Furthermore, studies often show that PFS requires a lower dosage to achieve effective results, contributing to cost savings for end-users. The reduction in iron ions post-treatment is also often lower with PFS, and it is generally considered innoxious.

For those seeking to improve their water purification processes, understanding these comparative advantages is crucial. NINGBO INNO PHARMCHEM CO.,LTD. champions Polymeric Ferrous Sulfate for its enhanced efficacy, broader operational window, and economic benefits, positioning it as a leading choice for modern water treatment challenges and a key player in the chemical flocculants in water market.
