anionic cationic flocculant polyacrylamide pam water

Polyacrylamide degradation and its implications in - Nature

HNH2 CH2OH O biodegradable, biocompatible OH HHHH Used as a flocculant in many industries, including waste and drinking water treatment. Due to low water solubility, must be prepared by dissolving in Common preparations include chitosan acetate (dissolved in acetic acid) and chitosan lactate (dissolved in lactic acid).

Polyacrylamide (abbreviated as PAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries. [1] Physicochemical properties

According to the relative molecular weight and electrical properties of polyacrylamide, PAM has different uses. Anionic polyacrylamide can be used as a pulp dispersant. 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.

May 15, 2021 · Difference and application of cationic, anionic and nonionic PAM. Polyacrylamide (PAM) is a kind of linear water-soluble polymer, which is the most commonly used water treatment agent in our sewage treatment! In our practical application, PAM can be divided into cationic, anionic and non-ionic three types. How to choose these three types of PAM

Cationic polyacrylamide copolymers (PAMs): environmental half

If cationic polyacrylamide is used in combination with anionic polyacrylamide, the reaction will cause precipitation. Therefore, amphoteric PAM is an ideal product. The amphoteric PAM molecules contain cationic groups and anionic groups, and have the characteristics of general cationic flocculants, so it will show more excellent performance.
