Product Introduction
In practical water treatment applications, the most common issue with nonionic polyacrylamide (NPAM) is not "whether it is effective," but the following key pain points:
Changes in water quality (turbidity / organic matter / temperature) lead to fluctuations in flocculation performance
Unstable product batches result in inconsistent user experience for customers
Difficult dissolution and complex operation make it easy for end users to use incorrectly
Difficulty in controlling dosage increases operating costs
Our NPAM is not simply about increasing molecular weight or improving specifications, but is systematically optimized around "stability + controllability + applicability":
Advantage 1
Wide molecular weight distribution structure design
Improves adaptability to different water qualities (low turbidity / high turbidity)
Advantage 2
High conversion rate and low residual process
Reduces monomer residue and improves environmental safety
Advantage 3
Optimized particle structure
Faster dissolution, more uniform dispersion, and reduced agglomeration issues
Advantage 4
Batch-locking production mechanism
Ensures consistent performance for long-term supply
👉 Direct value to buyers:
✔ Reduce after-sales issues
✔ Improve customer stability
✔ Reduce project operation risks
✔ Increase long-term repurchase rate
As a high-efficiency neutral flocculant, this product is particularly suitable for water treatment scenarios with high sensitivity to charge characteristics.

Mechanism of Action
Nonionic polyacrylamide mainly works through two mechanisms:
Adsorption Bridging Effect
High molecular chains adsorb multiple particles → forming large flocs
👉 Results:
✔ Increase sedimentation rate
✔ Reduce suspended solids
Net Capture and Sweeping Effect
A network structure is formed during sedimentation → capturing fine particles
👉 Results:
✔ Improve water clarity
✔ Improve treatment efficiency

Result:
✔ One product can cover multiple working conditions
✔ Reduce the frequency of changing product models
2. Small Flocs and Slow Sedimentation
Cause: Short molecular chains and insufficient bridging ability
Solution:
Increase molecular chain length and structural integrity
→ Enhance adsorption and bridging ability
Result:
✔ Larger and denser flocs
✔ Faster sedimentation
✔ More intuitive on-site performance
3. Slow Dissolution and Easy Agglomeration
Cause: Uneven particle structure
Solution:
Improve granulation and drying control
→ Enhance particle uniformity
Result:
✔ Faster dissolution

Product Process / Technical Strength
The core advantage lies in process control:
- Segmented temperature-controlled polymerization → prevent molecular chain breakage
- Aging time control → improve structural stability
- Mild drying → improve dissolution performance
👉 Ensure long-term product stability, rather than occasional good performance
This polyacrylamide for low-turbidity water treatment can still maintain good flocculation performance under low suspended solids concentration conditions.
