What is a high molecular weight polyacrylamide (PAM)?

Low molecular weight PAM can be used as a paper strengthening agent. Medium molecular weight polyacrylamide PAM is used as a retention and drainage aid. And high molecular weight polyacrylamide is used as a flocculant in the treatment of papermaking wastewater. At present, anionic PAM is most used in the paper industry.

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).

Is Pam a coagulant aid?

The addition of 100 mg/L PAM (coagulant aid) to SnCl 4 (main coagulant) resulted in colour and SS reductions of 94.3% and 95.9%, respectively. The Vs values obtained when SnCl 4 was used alone and with PAM as a coagulant aid were 0.4 and 0.61 cm/min, respectively.

Does polymer polyacrylamide interact with tin tetrachloride?

The main aim of this study is to assess how well the polymer polyacrylamide (PAM) could interact as a coagulant, coagulant aid or flocculant with the tetravalent metal coagulant tin tetrachloride (SnCl) in the removal of contaminants from leachate.

What is cationic polyacrylamide (CPAM)?

Cationic Polyacrylamide. In general, CPAM is white powder in appearance with an ionic degree ranging from 20% to 55%. It has the characteristics of high polymer electrolyte and is suitable for the treatment of wastewater with negative charge and rich in organic matter.

What is cationic Pam?

Cationic PAM can rapidly adsorb negatively charged particles in water, forming large flocs and effectively improving flocculation efficiency. Cationic PAM is especially suitable for treating negatively charged organic substances such as high-concentration colloids and suspended solids in wastewater treatment.
