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 cationic polyacrylamide?

Cationic polyacrylamide is projected to be the fastest-growing segment during the forecast period, due to the increasing usage of cationic polyacrylamide in various applications in diverse industries, such as additives in building & construction, color removal and desalination in wastewater treatment, and cell separation in biotechnological broths.

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.

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.

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 the largest segment of the polyacrylamide market?

Water treatment was the largest segment of the market, owing to the increasing demand for polyacrylamide from the water treatment industry. The global polyacrylamide market has been segmented based on types, such as anionic, cationic, and non-ionic, among others.
