Anionic Polyacrylamide

Overview Specification Benefits Application Areas Notes

Overview

Anionic polvacrylamide (APAM) is a water-soluble linear macromolecule focculant formed by the copolymerization of acrylamide and acrylate. it promotes the flocculation of particles by neutralizing the surface charge of suspended particlesthus destabilizing the particles in water. The destabilized particles adsorb with each other under the bridging effect of the active gene of macromolecule polymers. Finally, larger flocs are formed.

Benefits

Excellent flocculation effect ,quick sedimentation and economical low dosage levels.

High level of water clarification after process.

Wide PH range ofapplication(5-14)

Good compatibility with inorganic coagulant.

Application Areas

Waste water flocculation and settling

Sludge dewatering

Additive thickening

Construction and shield slurry

Oil industry

River dredging

Minerals selection and sewage disposal

Sand washing and sludge dewatering

Notes

Non-toxic, easily soluble in water and easily moisture absorption to caking

Splashes on hand and skin should be washed off with water immediately.

Proper storage temperature : 5℃~40℃, should be stored in cool and dry place.

Prepared liquid polyacrylamide is not suitable for long storage. The flocculating effect will decrease in 24 hours.

Low-hardness water with neutral PH (range 6-9) is suggested to dissolve polyacrylamide. Using underground water and recycled water would decrease the flocculating effect.
