flocculation The process in which particles in a colloid aggregate into larger clumps. Flocculation of clay particles in soil can be induced by the addition of calcium salts. Clay particles have an overall negative charge and therefore attract positive ions, such as Ca2+, which form bridges holding the particles together. Flocculation is also often observed in cultures of bacterial and yeast cells.
