(flok'yū-lŭs, -lī),
1. A tuft or shred of cotton or wool or anything resembling it.
2. A small lobe of the cerebellum at the posterior border of the middle cerebellar peduncle anterior to the biventer lobule; it is associated with the nodulus of the vermis; together, these two structures compose the flocculonodular lobe (vestibular part) of the cerebellum.
Synonym(s): floccule
[Mod. L. dim. of L. floccus, a tuft of wool]

5) commonly contains high concentrations of ASS oxidation products, such as iron floccules (Sammut et al.

Although both Al-PAM and HPAM can induce flocculation of clay fines, the size, shape, and structure of the floccules formed by these two polymers are different.
As mentioned earlier, Al-PAM can induce larger and denser spherical floccules.
Thirdly, suspended iron floccules were commonly observed at all of the sites impacted by ASS-affected waters, particularly after rainfall.
Iron floccules from Cattai Creek were observed extending for distances in excess of 1 kilometer downstream of its confluence with the Manning River and contaminated partially acidified and pH neutral waters in this estuary.
Therefore, that which the permeability experiments seek to investigate is destroyed prior to the flocculation experiments, which involve edge-to-face interactions and the formation of open card-house floccules.
