1. Its purifying effect on low-temperature, low-turbidity and heavily organic-polluted raw water is much better than other organic flocculant, furthermore, the treatment cost is lowered by 20%-80%.
2. It can lead to quick formation of flocculant (especially at low temperature) with big size and rapid precipitation service life of cellular filter of sedimentation basin.
3. It can adapt to a wide range of pH value (5−9), and can reduce the pH value and basicity after processing.
4. The dosage is smaller than that of other flocculants. It has wide adaptability to the waters at different temperatures and at different regions.
5. Higher basicity, lower corrosive, easy for operation, and long-term use of non-occlusion.
