Polydimethyldiallylammonium chloride 

1. The polymer body contains strong cationic groups and active adsorption groups, which can cause significant instability and flocculation of suspended particles and water-soluble substances containing negatively charged groups in water through electric neutralization and adsorption bridging. 

2. This product has the advantages of low dosage, large floc size, fast sedimentation rate, low residual turbidity, and low sludge production during use.

3. The pH value has a wide range of adaptability, ranging from 4 to 10.

4. This product can be widely used for source water purification and sewage treatment.
