What is polyacrylamide powder used for?
Polyacrylamide (PAM) powder is a big polymer. It is used in many industries. PAM serves as a flocculant, coagulant aid, thickener, and water-loss control agent.
✅ Main Uses of Polyacrylamide Powder
1. Water & Wastewater Treatment
Removes suspended solids, turbidity, and organic matter
Used in municipal sewage, industrial wastewater, mining tailwater, sand washing, stone cutting wastewater
Enhances sedimentation, flotation, and sludge dewatering efficiency
Applied in enhanced oil recovery (EOR/tertiary flooding)
Used as a drilling fluid additive to control water loss and stabilize boreholes
Improves viscosity and friction reduction in pipeline transportation
3. Mining & Mineral Processing
Accelerates solid-liquid separation
Improves tailing settling rate and recovery of valuable minerals
Reduces water consumption in recycling systems
Works as a retention and drainage aid, improving fiber retention
Enhances paper strength and reduces chemical loss
5. Municipal Sludge Dewatering
Added before filter press or centrifuge to improve sludge dryness
Reduces sludge volume and disposal cost
6. Construction & Tunneling
Used in bentonite slurry modification
Improves mud viscosity and anti-seepage performance
Can be applied as a grouting and soil stabilizer additive
7. Agriculture & Soil Conditioning
Helps retain water in soil, reducing irrigation frequency
Used as a soil erosion control agent on slopes and farmland
