Difference between Coagulation and Flocculation

MechanismChemistryMechanism of actionTreatmentIn coagulation, the forces responsible for keeping the particles apart after they contact, are reduced. Flocculation brings the de-established colloidal particles together and they form large aggregates. Both these techniques are employed in the treatment of water. Thus, we can understand the process of coagulation and flocculation with the help of examples derived from water treatment techniques.
