What are the different types of polyacrylamide (PAM)?

So PAM chemical can be used for petroleum exploration, water treatment, textile, papermaking, mineral processing, medicine, agriculture and other industries, etc. The polyacrylamide (PAM) can be divided into four types, they are anionic PAM, cationic PAM, nonionic and amphoteric PAM. The following are their detailed introduction and specifications.

Which is better cationic or anionic polyacrylamide?

Cationic PAM is especially suitable for treating negatively charged organic substances such as high-concentration colloids and suspended solids in wastewater treatment. Due to its complex production process and superior performance, cationic PAM is usually priced higher than anionic polyacrylamide.

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).

Is Pam a water soluble polymer?

The polyacrylamide flocculant (PAM) is a linear water-soluble polymer and is one of the most widely used types of water-soluble polymers. PAM and its derivatives can be used as efficient flocculants, …

Why is anionic polyacrylamide used in wastewater treatment?

Due to its negatively charged characteristics, anionic polyacrylamide can effectively combine with positively charged particles in water, forming larger flocs and promoting sedimentation of particles. Anionic polyacrylamide is suitable for treating positively charged particles such as suspended solids and colloids in wastewater.

What is anionic polyacrylamide used for?

Anionic polyacrylamide is suitable for treating positively charged particles such as suspended solids and colloids in wastewater. Compared to cationic PAM, anionic polyacrylamide is usually less expensive and is suitable for large-scale use.
