The quest for clean water relies heavily on advanced chemical treatments that can efficiently remove impurities. Polymeric Ferric Sulfate (PFS) has emerged as a highly effective inorganic polymer coagulant, prized for its robust performance in both industrial wastewater and drinking water purification. To truly appreciate its capabilities, it’s essential to understand the chemistry behind its operation. As a dedicated manufacturer and supplier, we at NINGBO INNO PHARMCHEM CO.,LTD. are keen to share insights into how PFS delivers superior water clarity.

The Science of Coagulation with PFS

PFS functions through a sophisticated process involving hydrolysis, charge neutralization, and bridging mechanisms. When introduced into water, the polymeric iron salt undergoes hydrolysis, releasing positively charged iron species. These species play a crucial role in destabilizing negatively charged colloidal particles suspended in the water.

The primary mechanisms by which PFS achieves purification include:

  • Charge Neutralization: The positively charged iron ions in PFS neutralize the negative surface charges of suspended particles and dissolved organic matter. This reduces electrostatic repulsion between particles, allowing them to aggregate.
  • Adsorption and Bridging: As a polymer, PFS possesses a large surface area and multiple active sites. It can adsorb onto the neutralized particles, forming bridges between them. This bridging action creates larger, heavier agglomerates known as flocs. The polymeric structure is particularly adept at this bridging, leading to more stable and robust flocs compared to simpler iron salts.
  • Sweep Flocculation: As hydrolysis progresses, insoluble ferric hydroxide precipitates can form. These precipitates act as a 'net,' sweeping through the water and trapping remaining suspended particles and dissolved pollutants as they settle.

Key Advantages Derived from its Mechanism

The effectiveness of these mechanisms translates into tangible benefits:

  • Fast Settling: The large, dense flocs formed by PFS settle rapidly, significantly reducing treatment time and improving the efficiency of sedimentation processes.
  • High Removal Efficiency: This dual action of charge neutralization and bridging ensures a high removal rate for turbidity, color, COD, BOD, and heavy metals.
  • Adaptability: PFS’s performance is less affected by variations in water temperature and pH, making it a versatile coagulant for diverse water sources. Its low corrosivity is also a significant advantage when considering equipment longevity.
