Ensuring the safety and purity of drinking water is paramount for public health. NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing high-quality water treatment chemicals, and our Polymeric Ferric Sulfate (PFS) plays a crucial role in optimizing the purification of potable water. This article explores the specific applications and benefits of using high-purity PFS in drinking water treatment plants.

Drinking water sources, such as rivers, lakes, and reservoirs, often contain suspended solids, organic matter, color, and potentially harmful microorganisms or heavy metals. The purification process aims to remove these impurities to meet stringent health and aesthetic standards. PFS is an advanced inorganic polymer coagulant that excels in this process.

Mechanism of Action in Drinking Water:

When added to raw water, PFS works through a dual mechanism: charge neutralization and adsorption bridging. Its polynuclear iron species effectively neutralize the negative charges on colloidal particles and suspended solids, destabilizing them. Following destabilization, the long polymer chains of PFS adsorb onto these particles, forming large, dense, and fast-settling flocs. These flocs efficiently entrap impurities, facilitating their removal through sedimentation and filtration.

Key Benefits of Using High-Purity PFS for Potable Water:

  1. Superior Removal of Impurities: High-purity PFS is highly effective in removing turbidity, color, organic matter, and even certain trace contaminants like arsenic and heavy metals. This ensures that the treated water is clear, aesthetically pleasing, and safe for consumption. The efficacy of high purity PFS coagulant is well-documented in ensuring water clarity.
  2. Low Dosage Requirements: Due to its advanced molecular structure and high efficiency, PFS requires significantly lower dosages compared to traditional coagulants like alum or ferric chloride. This reduces chemical consumption and overall treatment costs, making it a cost-effective water treatment agent.
  3. Reduced Residual Aluminum or Iron: Compared to alum, PFS leaves significantly lower residual aluminum in the treated water, which is important as excessive aluminum can be a health concern. Similarly, it is formulated to minimize residual iron, preventing a metallic taste or color in the final product.
  4. Effective Performance Across Wide Conditions: PFS maintains its effectiveness over a broad pH range (4-11) and is resilient to variations in water temperature. This adaptability simplifies plant operations and ensures consistent water quality, regardless of source water fluctuations.
  5. Environmentally Friendly: As an eco-friendly water purification chemical, PFS does not introduce harmful heavy metals into the water and typically produces less sludge, easing disposal challenges and reducing the overall environmental impact.

Applications in Water Treatment Plants:

PFS is widely used in various stages of drinking water treatment, including pre-treatment and clarification. It effectively removes natural organic matter that can form disinfection byproducts, reduces the load on downstream filtration processes, and improves the overall efficiency of the water purification train.
