Dispersion and flocculation
WebFlocculation and Dispersion in Soils Soils are generally in an aggregated state, which means the individual particles are stuck together to form clumps. These clumps are known as aggregates or floccules. … WebFlocculation and Dispersion. Flocculation is the process, where the individual particles of clay are coagulated to form floccular aggregates. The degree and permanence of flocculation depend upon the nature of the ions present. For example, calcium and hydrogen tend to increase flocculation.
