I. Product Overview 

Anionic polyacrylamide (APAM) is a water-soluble polymer mainly used for flocculation and sedimentation in various industrial wastewater 

treatments, such as wastewater from steel mills, electroplating plants, metallurgical plants, and coal washing plants, as well as sludge dewatering. 

It can also be used for drinking water clarification and purification. Because its molecular chain contains a certain number of polar groups, it can 

adsorb suspended solid particles in water, bridging the particles or neutralizing their charges to form large flocs, thus accelerating the 

sedimentation of particles in suspension and significantly speeding up solution clarification and promoting filtration.

II. Functions: Anionic polyacrylamide possesses the following functions

1. Clarification and purification;

2. Sedimentation promotion;

3. Filtration promotion;

4. Thickening and other functions.

It can fully meet the requirements of various fields such as wastewater treatment, sludge thickening and dewatering, mineral processing, 

coal washing, and papermaking. 

III. Usage and Precautions

1. Prepare a 0.1% aqueous solution using neutral water free of salts and impurities.

2. When dissolving, evenly sprinkle the anionic polyacrylamide product into the stirred water, maintaining a stirring speed of 100-300 rpm. 

Appropriate heating (< 60°C) can accelerate dissolution.

3. Adjust the pH of the treated solution to ensure the anionic polyacrylamide product functions effectively (select the optimal pH and dosage of 

this series of products through experimentation).

4. When adding the anionic polyacrylamide product solution, accelerate mixing with the treated solution. Once flocculation occurs, slow down the 

stirring speed to promote floc growth and accelerate sedimentation.
