At NINGBO INNO PHARMCHEM CO.,LTD., we are committed to providing high-quality chemical solutions that address critical water treatment needs. A cornerstone of our product line is Polyacrylamide (PAM), a highly effective flocculant whose scientific principles underpin many modern water purification strategies. Understanding how PAM works is key to appreciating its broad applicability and effectiveness.

Flocculation is a fundamental process in water treatment that aims to destabilize and aggregate small, dispersed particles into larger, settleable clumps known as flocs. These dispersed particles, which contribute to turbidity and the presence of suspended solids, are often too small and too light to be easily removed by simple settling or filtration. PAM, a synthetic polymer, acts as a bridge or a binder, facilitating this aggregation.

The efficacy of PAM as a flocculant stems from its molecular structure and chemical properties. PAM is a long-chain polymer, and depending on its formulation, it can carry positive (cationic), negative (anionic), or no charge (non-ionic). In water treatment, the process typically involves two main mechanisms for PAM's action:

  1. Charge Neutralization: Many suspended particles in water, especially organic matter and colloidal suspensions, carry a negative surface charge. Cationic PAM, with its positive charge, is attracted to these particles. When added to the water, the positive charges on the PAM molecules neutralize the negative charges on the suspended particles. This reduction in electrostatic repulsion causes the particles to approach each other and begin to aggregate.
  2. Bridging: PAM’s long molecular chains can adsorb onto multiple particles simultaneously. Once adsorbed, the extended polymer chain acts as a physical bridge, linking these particles together. This bridging action is particularly effective with higher molecular weight PAMs, creating larger and stronger flocs.

The specific type and molecular weight of PAM chosen depend on the nature of the contaminants in the water being treated. For example, cationic PAM is highly effective for treating industrial wastewater with high organic content and negatively charged suspended solids, while anionic PAM might be more suitable for certain mineral processing applications. The careful selection of the correct polyacrylamide product, coupled with precise dosage control, is essential for achieving optimal water clarification and solids removal.
