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.

What is nonionic polyacrylamide PAM?

Nonionic polyacrylamide PAM is mainly used for flocculation and sedimentation of various industrial wastewater, and clarification and disposal of precipitation. Many friends have little knowledge of this type of polyacrylamide. Today, I will introduce the characteristics, efficacy, and usage of nonionic polyacrylamide PAM.

What is polyacrylamide (PAM)?

Enteromorpha prolifera polysaccharide based coagulant aid for humic acids removal and ultrafiltration membrane fouling control Polyacrylamide (PAM) has been used as a coagulant aid in water treatment process for past decades, but it has caused great damages to human nervous system.

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.

Is non ionic polyacrylamide a water soluble polymer?

Non-ionic polyacrylamide is a water-soluble high molecular polymer or polyelectrolyte. The characteristics of nonionic polyacrylamide PAM can be simply divided into the following three points: It has relatively good water solubility and can be completely dissolved even in cold water.

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.
