Nonionic Polyacrylamide PAM Flocculant with Superior Sludge Dewatering
NPAM-4801 is a high-efficiency, high-molecular-weight polymer appearing as a white granular solid. It boasts an active content of ≥88% and a molecular weight between 8 and 10 million. As a nonionic polymer, its molecular chain contains no ionic functional groups. Its flocculation mechanism is primarily based on hydrogen bonding and van der Waals interactions between amide groups and suspended particles, achieving highly efficient aggregation via robust adsorption and bridging.

Performance & Applications
- Metallurgical & Mining: NPAM-4801 is extensively used across metallurgical, mineral processing, and metalworking sectors for treating waste acid streams. It effectively eliminates heavy metal ions and suspended solids while maintaining consistent performance even in highly acidic environments.
- Industrial Wastewater: Suitable for primary, secondary, and tertiary treatment stages in chemical, electroplating, and electronic wastewater systems. It demonstrates exceptional removal of emulsified oils, colloidal substances, dyes, and other contaminants, with strong adaptability to extreme pH variations.
- Papermaking Industry: Functions both as a strength additive and wastewater treatment agent. It improves physical characteristics of paper and efficiently treats process water and mid-stage effluents, enabling effective fiber recovery and water recycling.
Advantages
- Broad pH adaptability (3.0–14.0): allowing reliable operation under challenging water conditions with high chemical stability.
- High salt resistance: its nonionic nature avoids disruption by polyvalent metal ions, ensuring consistent performance in high-salinity and high-hardness water.
- Superior Floc Formation: Forms large, dense, and rapidly settling flocs, resulting in superior mud-water separation and significantly improved processing efficiency.
