Anionic Polyacrylamide, Water Treatment, PAM

Anionic Polyacrylamide (APAM) is a water-soluble polymer, mainly used for flocculation and sedimentation of various industrial wastewater, sedimentation and clarification treatment, such as steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater, and other sewage treatment, sludge dewatering. It can also be used for clarification and purification of drinking water. Due to the presence of a certain amount of polar groups in its molecular chain, it can bridge between particles by adsorbing solid particles suspended in water or coagulate particles to form large floccules through charge neutralization. Therefore, it can accelerate the sedimentation of particles in the suspension, significantly accelerating solution clarification, and promoting filtration.


Polyacrylamide is one of the flocculants, English code name (PAM). Main classification: anionic polyacrylamide (APAM), cationic polyacrylamide (CPAM), and nonionic polyacrylamide (NPAM). It is widely used in oil exploration, water treatment, textile, printing and dyeing, paper making, mineral processing, coal washing, medicine, sugar making, aquaculture, building materials, agriculture, and other industries. It is known as "Baiye Additive" and also known as "Universal Product".
