What is anionic polyacrylamide (PAM)?

Anionic polyacrylamide (PAM) possesses interconnected and active groups that establish robust bonds with the surface of suspended colloids, promoting the formation of coarse particles among the suspended solids and a mixture of insoluble particles in water (Irfan et al. 2017).

What are the different types of polyacrylamide (PAM)?

According to its ionic properties, PAM is divided into three main types: cationic (Cationic PAM, CPAM), anionic (Anionic PAM, APAM) and nonionic (Nonionic PAM, NPAM). These three types have significant differences in structure, function and application. 1. Cationic polyacrylamide (Cationic PAM, CPAM) Structure and properties:

What is polyacrylamide (PAM) used for?

In water treatment and industrial production, polyacrylamide (PAM) is widely used as an important flocculant in wastewater treatment, pulp production, ore processing, and other fields. Based on its ionic properties, PAM can be divided into anionic polyacrylamide (APAM) and cationic PAM (CPAM).

How does anionic polyacrylamide (Apam) work?

Anionic polyacrylamide (APAM) carries a negative charge, and its molecular chain contains polar groups such as carboxyl groups. These groups can neutralize charges with positively charged particles in water and form larger flocs through bridging, thus accelerating the sedimentation of particles in the suspension.

What is the difference between Pam and CPAM?

Based on its ionic properties, PAM can be divided into anionic polyacrylamide (APAM) and cationic PAM (CPAM). Understanding the difference between the two is crucial for selecting the appropriate product.

What is a nonionic polymer (Pam)?

Nonionic PAM is a high molecular polymer or polyelectrolyte with a certain amount of polar genes in its molecular chain. It can adsorb solid particles suspended in water and bridge between particles to form large floccules, accelerate the sedimentation of particles in suspension, accelerate the clarification of solution, and promote filtration.
