Flocculation is a fundamental process in water and wastewater treatment, aimed at removing suspended solids that cloud the water and can carry impurities. At NINGBO INNO PHARMCHEM CO.,LTD., we provide Polyacrylamide (PAM), a highly effective chemical agent that significantly enhances this process. Understanding the science behind flocculation helps users appreciate the value and functionality of our products.

What is Flocculation?

Flocculation is a physical-chemical process where small, dispersed particles suspended in a liquid aggregate to form larger, heavier particles called flocs. In water treatment, these suspended solids are often destabilized by a preceding process called coagulation, which neutralizes their electrical charges. Flocculation then builds upon this destabilization by using chemical agents to physically link these particles together.

How Polyacrylamide Facilitates Flocculation:

Polyacrylamide, a synthetic, water-soluble polymer, is a highly efficient flocculant. Its effectiveness stems from its molecular structure and how it interacts with suspended particles:

  • High Molecular Weight: PAM molecules are very long, essentially acting like molecular bridges.
  • Adsorption and Bridging: Once added to water, PAM molecules adsorb onto the surface of the destabilized particles. Due to their length, a single PAM molecule can simultaneously adsorb onto multiple particles, effectively linking them together into a larger floc structure. This bridging mechanism is key to forming robust flocs.
  • Charge Interaction (for ionic PAM): Cationic PAM (CPAM) and Anionic PAM (APAM) also contribute through charge attraction. If particles are negatively charged, CPAM can bridge them via electrostatic attraction. Conversely, APAM can bind to positively charged particles.

The result is the formation of larger, denser flocs that settle much faster than the original dispersed particles. This significantly improves the efficiency of subsequent sedimentation or filtration steps, leading to clearer water.
