The effectiveness of Polyacrylamide (PAM) in addressing industrial water challenges, particularly in reducing Chemical Oxygen Demand (COD), hinges on selecting the correct type of polymer. NINGBO INNO PHARMCHEM CO.,LTD. guides industries through the nuances of anionic, cationic, and non-ionic PAM to ensure optimal performance. Choosing the right wastewater treatment chemicals is critical for achieving desired outcomes.

Anionic PAM, characterized by its negatively charged polymer chains, is highly effective in applications where the suspended solids in wastewater carry a positive charge or where flocculation of negatively charged particles is desired. Its strong performance in bridging and charge neutralization makes it an excellent choice for general flocculation and sedimentation processes, contributing significantly to reduce cod in wastewater treatment. The specific properties of anionic polyacrylamide viscosity also make it valuable for thickening applications.

Cationic PAM, with its positively charged polymer chains, is particularly adept at interacting with negatively charged suspended solids and colloidal particles commonly found in industrial effluents, including many types of sludge. This makes it the preferred choice for sludge dewatering, where its strong electrostatic attraction efficiently destabilizes and aggregates particles. The efficacy of cationic polyacrylamide sludge dewatering is well-established, leading to drier sludge cakes and more manageable waste.

Non-ionic PAM, which carries no net electrical charge, functions primarily through bridging mechanisms. It is often used in specific applications where charge interactions are less critical or where a neutral charge is preferred to avoid unwanted side effects. Its broad polyacrylamide water solubility ensures it can be applied across a range of conditions.
