Flocculation - Wikipedia

WebThe flocculation process is dynam ically active which is directly affected by its environmental conditions, primarily bein g dependent on a complex set of interactions between sediment, fluid and flow within which the par ticles aggregation plays a major role (Manning, 2004a). WebFlocculation 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. ccleaner professional plus 2yr
