    This is known as the flocculation process. For example, many minerals such as calcite and heavy metals such as copper can be effectively flocced. Floccing means removing suspended solids from a water solution by an anionic polymer or flocculant or flocculent. An anionic polymer flocculant causes tiny particles to come together. When they do

    Flocculation is a special phenomenon for fine sediment or silt in reservoirs and estuaries. Flocculation usually results in changes of size, morphology, and settling velocity of sediment particles and finally changes of bed topography of reservoirs and estuaries.
