natural flocculants for the treatment of wastewaters

Natural flocculants for the treatment of wastewaters

Flocculation is a water and wastewater treatment technology whereby the large aggregation of flocs in water can be formed and be later separated through sedimentation. This review aims to provide the recent developments in the field of natural flocculants and their prospects for the effective removal of dyes or heavy metals from aqueous solutions.

water soluble polymer flocculants: synthesis

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
