What is anionic polyacrylamide used for?

Polyacrylamide finds applications in pulp and paper production, agriculture, food processing, mining, and as a flocculant in wastewater treatment. Anionic polyacrylamide is suitable for high concentrations of positively charged inorganic suspensions, as well as coarse suspended particles (0.01-1mm), with a Ph value of neutral or alkaline solution.

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.

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.

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 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 do I choose the right polyacrylamide product?

When selecting the appropriate polyacrylamide product, the following factors need to be considered: Understanding the pH value, properties of suspended particles (such as charge, particle size, concentration), and organic content of the water to be treated will help select the appropriate anionic polyacrylamide or cationic PAM.
