Water Soluble Polymer Flocculants: Synthesis

Flocculants with less than 1% charged functional groups are considered as nonionic flocculants. 34 Nonionic flocculants normally have high molecular weights, which helps them flocculate suspended particles through the bridging mechanism. 35 Polyacrylamide is the most important water soluble nonionic flocculant because its monomer, acrylamide

Water Soluble Polymer Flocculants: Synthesis

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

Polymer Flocculants | SpringerLink

Definition Polymer?occulants are water-soluble polymers which can form?ocs from individual small particles in asuspension by adsorbing on particles and causing destabilization through bridging or chargeneutralization. Polymer ?occulants are high molecular weight polymers and have hydrogen-bonding groups and/orionic groups in the molecule.
