Flocculation/coagulation processes are a typical solution for solid/liquid purification processes as they can provide efficient and rapid solid-liquid separation in large quantities of effluents. These advantages make such processes a method chosen very often in wastewater treatment industries [4].,A Comparative Study on the Flocculation of Silica … – MDPI ,Although flocculation with synthetic polymers is a cost-effective, efficient, and facile water treatment method, it consumes huge amounts of synthetic polyelectrolytes whereby, e.g., toxic, unreacted monomers, or residual polyelectrolytes themselves can pose a risk to, e.g., aquatic life [ 4, 5, 6, 7 ].,A model of flocculation – ScienceDirect ,We propose a model of flocculation based on the assumption that effective flocculants pervade large volumes of liquids in the suspensions. Since many flocculants are polymers, good flocculants according to the model should have large radii of gyration RG.
