Web9.5.2.2.1 Flocculation. Flocculation is the most conventional and effective method among the aforementioned processes of microalgae harvesting of large-volume of culture. Flocculation is the preparatory step to all other harvesting methods such as filtration, floatation, or gravity sedimentation. Flocculation and coagulation process is often ... WebFlocculation, in the field of chemistry, is a process by which colloidal particles come out of suspension to sediment under the form of floc or flake, either spontaneously or due to the addition of a clarifying agent. The action differs from precipitation in that, prior to flocculation, colloids are merely suspended, under the form of a stable ...
