Coagulation Flocculation and Precipitation in Water and

Coagulation is essentially a time independent process because the term only involves the process of overcoming various forces on the surface of a particle so that the gravitational forces can take over to settle the particles On the other hand flocculation is a time consuming process where the agglomerates are formed that become larger and
