Selecting the right coagulant is a critical decision for any water treatment facility. While traditional coagulants like Aluminum Sulfate (Alum) and Ferric Chloride have been mainstays for years, Polymeric Ferric Sulfate (PFS) has emerged as a superior alternative, offering enhanced performance and economic advantages. NINGBO INNO PHARMCHEM CO.,LTD., a leading manufacturer and supplier of PFS in China, highlights the key differences that make PFS the preferred choice.

Traditional Coagulants: The Baseline

Traditional coagulants, such as Aluminum Sulfate and Ferric Chloride, work by destabilizing suspended particles through charge neutralization and forming hydroxide precipitates. However, they often have limitations:

  • Narrower Effective pH Range: Their performance can be significantly affected by fluctuations in water pH, often requiring extensive pH adjustment.
  • Higher Dosage Requirements: To achieve comparable results, larger quantities are typically needed, increasing chemical costs.
  • Formation of Finer Flocs: The flocs formed are often smaller and less dense, leading to slower settling times and potential carry-over of fine particles.
  • Potential for Residual Contaminants: For example, aluminum-based coagulants can leave residual aluminum in treated water, which is a concern for potability.

The Superiority of Polymeric Ferric Sulfate (PFS)

PFS, with its advanced polymeric structure, addresses many of the limitations of traditional coagulants:

  • Wider pH Applicability: PFS is effective over a much broader pH range (often 4-11), reducing the need for costly pH conditioning and ensuring consistent performance.
  • Lower Dosage for Higher Efficiency: The high charge density and molecular weight of PFS allow it to achieve superior removal of turbidity, COD, BOD, color, and heavy metals at significantly lower dosages. This translates to direct cost savings for our customers.
  • Faster and Denser Floc Formation: PFS creates larger, denser flocs that settle rapidly, improving sedimentation efficiency and reducing the load on downstream filtration processes.
  • Reduced Sludge Production: The efficient nature of PFS often leads to less sludge formation compared to traditional coagulants.
  • Minimal Residual Iron: While it is an iron-based coagulant, PFS generally leaves lower residual iron concentrations in treated water compared to monomeric iron salts when used appropriately.
