Water Soluble Polymer Flocculants: Synthesis, Characterization, and

Polymer adsorption can occur through hydrogen bonding (polyacrylamide on silica silanol groups), electrostatic interaction (cationic polymers on negatively charged sludge), hydrophobic interaction (poly (vinyl alcohol) on silver iodide), and ion bridging (anionic polyacrylamide on negatively charged clays with the help of divalent calcium ion). 7

Laboratory test of waste mud treated by the flocculation-vacuum-curing

Anionic polyacrylamide (APAM), which has a molecular weight of 6 million, was selected as the organic flocculant in the test. The reason for choosing APAM as a flocculant is that APAM undergoes a chemical reaction in mud, which neutralizes the surface charge of small particles and collides and aggregates to form new large particles.

In this study, polyacrylamide (PAM) was used as the flocculant. PAM, a white crystal with the chemical formula [C3H5NO]n, is an organic polymer flocculant. Based on its ionic properties, it is categorized into cationic polyacrylamide (CPAM), anionic polyacrylamide (APAM), and nonionic polyacrylamide (NPAM).
