Difference Between Coagulation and Flocculation in Water

coagulation is a chemical process and flocculation is a physical process, in coagulation, the process involves the utilization of a coagulant that has the ability to destabilize the charged particles which are not settleable whilst flocculation involves a similar destabilization process that is achieved through physical mixing and by adding

Removal is generally accomplished by coagulation, flocculation, and sedimentation. The combination of these three processes is referred to as conventional clarification. Coagulation is the process of destabilization by charge neutralization. Once neutralized, particles no longer repel each other and can be brought together.

Particle Aggregation by Coagulation and Flocculation

The most common are coagulation, by reduction of inter-particle electrostatic repulsion, flocculation by bridging particles with water soluble polymeric agents called flocculants and oil agglomeration, in which an oily hydrocarbon is used to agglomerate hydrophobic particles suspended in water, hence producing hydrophobic agglomerates.

The coagulation-flocculation experiment was carried out using a flocculator with six paddles, at room temperature. The conventional multifactor experiment was employed whereby optimization was carried out by varying a single factor while keeping all other factors constant. This method is also called the OFAT (one-factor-at a-time) method.
