How are polymeric flocculants classified?

Polymeric flocculants cause finely divided particles to agglomerate and segregate into flocs. They are classified according to their charges, which can be cationic, anionic, or non-ionic. They can be classified based on whether they are natural or man-made as well.

Which group is found in cationic polymeric flocculants?

Positively charged groups such as amino, imino, or quaternary amino are found in cationic polymeric flocculants.

Do cationic and anionic Pam improve particle flocculation characteristics?

The results revealed that when the ionic strength and MW were low, anionic flocculation characteristics improved, but cationic flocculants performed better when the cationic strength and MW were high. The success of anionic and cationic PAM in flocculation can be related to particle charges that allow for particle flocculation with polymers.

Why are polymeric flocculants used in industrial effluent treatment?

Polymeric flocculants, synthetic as well as natural have become very popular in industrial effluent treatment due to their natural inertness to pH changes, high efficiency with low dosage, and easy handling (Singh et al., 2000).

What is nonionic powder flocculants / polyacrylamides (ndpam)?

Nonionic powder flocculants can be produced with very high molecular weights, giving it the capability to form large, rapid-settling, good-compacting flocs. We produce nonionic powder flocculants / polyacrylamides (NDPAM) in a standard range plus in high and low molecular weights.

What are cationic flocculants?

Cationic flocculants Water-soluble cationic polymers are typically categorised into three groups: ammonium, sulfonium and phosphonium quaternaries.10 Cationic polymers can bind strongly to negatively charged particles, and thus these polymers are often used in a wide range of industrial applications.
