What is cationic polyacrylamide?

Cationic Polyacrylamide is white power or granule, the degree of ion is from 5% to 80%, soluble, good water solubility, can be dissolved in water at any percentage and be undissolved in organic solvents. CPAM shows characteristics of high polymer electrolyte, suitable for wastewater treatment with a negative charge and rich organic matter.

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.

Why is anionic polyacrylamide important in water treatment?

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. Anionic polyacrylamide plays a significant role in water treatment in the following aspects:

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 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.

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.
