What is Non-ionic Polyacrylamide?

Non-ionic polyacrylamide (NPAM) is a water-soluble polymer known for its excellent flocculation, thickening, and adsorption properties. Unlike anionic or cationic PAM, it carries no charge, making it suitable for high-solids, high-salinity, or variable pH water conditions.

 

Applications of Non-ionic Polyacrylamide

1.Wastewater Treatment: Used in municipal and industrial (e.g., papermaking, dyeing, electroplating) wastewater treatment to remove suspended solids and colloidal particles.

2.Mining & Metallurgy: Enhances sedimentation and dewatering in mineral processing and tailings management.

3.Oil Extraction: Acts as a viscosity modifier in drilling fluids and improves oil recovery in enhanced oil recovery (EOR).

4.Agriculture: Serves as a soil conditioner to improve water retention and reduce erosion.

5.Food & Chemical Industries: Used in sugar clarification, fermentation broth separation, and other processes.

 

Functions of Non-ionic Polyacrylamide

*Flocculation: Aggregates fine particles into larger flocs for faster settling.

*Thickening: Increases solution viscosity, useful in mining and construction.

*Drag Reduction: Reduces friction in pipelines for efficient fluid transport.

 

Precautions When Using Non-ionic Polyacrylamide

–Dissolution Method: Slowly dissolve in clean water (50-200 rpm stirring) to prevent clumping.

–Dosage Control: Overdosing may reduce efficiency; conduct jar tests for optimal dosing.

–Storage: Keep in a cool, dry place away from moisture and high temperatures.

–Safety Measures: Wear gloves and goggles to avoid skin/eye contact.

 

Conclusion

Non-ionic polyacrylamide is a versatile chemical widely used in water treatment, mining, oil extraction, and agriculture. Proper usage ensures optimal performance and safety.
