What does deflocculate mean?
Deflocculate means to break up or disperse an aggregate of particles, especially loose clumps called flocs. A suspension may form flocs when dispersed particles gather together; deflocculating it separates those particles again. The word is chiefly used in chemistry, materials science, mineral processing, and other technical fields, where processes involving clay, sediment, pigments, or other suspended materials may require controlled dispersion. In general writing, it is an uncommon and distinctly specialist alternative to words such as “disperse” or “break up.” Its main contrast is with “flocculate,” the process of forming flocs. Deflocculate is therefore best understood as the verb describing the dispersal or reversal of flocculation.
verbTo break up or disperse flocs or other aggregates into separate particles, especially in a suspension. The term is chiefly used in technical and scientific contexts.
- To break up or disperse an aggregate of particles, especially a floc in a suspension or slurry.
"The dispersant helped deflocculate the sediment before the sample was analyzed."
"The dispersant helped deflocculate the sediment before the sample was analyzed."
"Engineers deflocculated the clay mixture to prevent the particles from forming dense aggregates."
“Deflocculate” is the technical undo button for forming clumps: it disperses the flocs again.

Etymology of deflocculate
The word is formed in English from the prefix de-, meaning removal or reversal, and a stem related to Latin flocculus, a diminutive of floccus, meaning a lock or tuft of wool. The same Latin root underlies flocculate, flocculation, and flocculent. In its technical sense, the prefix distinguishes the dispersal of particles from the process of gathering them into flocs.
