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, …

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 a high molecular weight polyacrylamide (PAM)?

Low molecular weight PAM can be used as a paper strengthening agent. Medium molecular weight polyacrylamide PAM is used as a retention and drainage aid. And high molecular weight polyacrylamide is used as a flocculant in the treatment of papermaking wastewater. At present, anionic PAM is most used in the paper industry.

What is the difference between Pam and sewage treatment agent?

Usage differences are as follows: Sewage treatment agent When the suspended sewage is acidic, the use of non-ionic polyacrylamide as a flocculant is more suitable. This is because PAM has an adsorption bridging effect, which makes the suspended particles produce flocculation and precipitation, thus achieving the purpose of purifying sewage.

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.
