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 the difference between polyacrylamide anion and cationic Pam?

polyacrylamide anion type Pam 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. Polyacrylamide cationic Pam is suitable for suspending materials with negative charge and organic matter.

What are the different types of polyacrylamide?

Based on its ionic characteristics, polyacrylamide is mainly divided into three categories: anionic, cationic, and non-ionic. Amphoteric polyacrylamide is also used in specific fields. This article will delve into the differences between anionic polyacrylamide and cationic polyacrylamide in application.

What is anionic polyacrylamide (Apam)?

Anionic polyacrylamide (Anionic PAM, APAM) Structure and properties: Anionic PAM is a water-soluble polymer. By introducing these anionic groups on the polymer backbone, APAM can react with positively charged substances. It is mainly used for flocculation, sedimentation and clarification of various industrial wastewaters.

Is polyacrylamide ionic or cationic?

Due to its excellent flocculation, thickening, and enhancing properties, polyacrylamide is widely used in various industrial fields such as water treatment, paper making, petroleum, coal, and mining metallurgy. Based on its ionic characteristics, polyacrylamide is mainly divided into three categories: anionic, cationic, and non-ionic.

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.
