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 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 anionic Polyacrylamide is used in industrial wastewater treatment?

Industrial wastewater treatment Anionic polyacrylamide has good effect on the treatment of wastewater with suspended particles ,high concentration, positive charge and neutral or alkaline pH value, steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater and other wastewater.

What is the effect of cationic polyacrylamide?

The effect of cationic polyacrylamide is several times or tens of times higher than that of anionic, non-ionic polyacrylamide or inorganic salt, because this kind of wastewater generally has negative charge. 2. Application of anionic polyacrylamide (1). Industrial wastewater treatment

What are the different types of polyacrylamide water treatment?

Description: According to ionic characteristics, it can be divided into four types, non-ionic polyacrylamide NPAM, anionic polyacrylamide APAM, cationic polyacrylamide CPAM and amphoteric polyacrylamide. At present, the PAM water treatment is generally anionic type.

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).
