Cationic Polyacrylamide (CPAM): Visual Flocculation Results and Comparison
Cationic Polyacrylamide quickly neutralizes particles to form dense flocs. Results show rapid sedimentation and high supernatant clarity, drastically improving the overall wastewater treatment performance.

Cationic vs. Anionic Polyacrylamide (PAM) Selection Guide
| Selection Dimension | Cationic Polyacrylamide | Anionic Polyacrylamide |
| 1. Sludge/Water Type | Organic sludge or Municipal sludge (e.g., domestic sewage, food processing, fermentation industry wastewater). | Inorganic sludge or High-turbidity wastewater (e.g., sand washing, metallurgy, mining, coal washing, ceramic factory wastewater). |
| 2. Colloidal Charge | Suspended particles carry a negative charge (most organic matter and bacteria are negatively charged). | Suspended particles carry a positive charge (mainly metal oxides and inorganic particles). |
| 3. Main Mechanism | Primarily Charge Neutralization (compressing the double layer), supplemented by bridging. | Primarily Adsorption Bridging (long chains wrapping around particles). |
| 4. Applicable Process | Suitable for Sludge Dewatering (plate and frame, belt press, centrifuge), and flocculation in primary/secondary clarifiers. | Suitable for Solid-Liquid Separation and Thickening/Sedimentation (e.g., thickeners, sedimentation tanks), typically used in the pretreatment stage. |
| 5. pH Applicability | Suitable for neutral or weakly alkaline environments. Prone to failure in strong acids or bases. | Suitable for alkaline environments. Not suitable for highly acidic water (pH < 4), as it may dissolve poorly or fail. |
| 6. Floc Characteristics | Flocs are compact and strong, resistant to shear, suitable for mechanical dewatering. | Flocs are large and coarse, settle quickly, but are easily broken under shear. |
| 7. Economic Consideration | Typically higher cost, as treating organic sludge is more difficult and requires specific molecular configurations. | Relatively lower cost, commonly used for large-volume primary treatment, offering high cost-effectiveness. |
