Includes bibliographic references. "In the history of environmental science, there has probably been no greater struggle than the attempt to. control the impact of the sediment and solids generated by nature and human influence (including industrial processing) on the terrestrial and aquatic environments and on socioeconomics in general. Flocculation is a process inherent within both natural and engineered systems, such as wastewater treatment and is simply the aggregating of smaller particles together to form larger composite particles via various physical, chemical and biological interactions. These larger composite particles behave differently in terms of their physical (e.g. transport, settling), chemical (e.g. contaminant uptake and transformation), and biological (e.g. community structure activities and metabolism) behaviour relative to their constituent individual particles due to differences in size, shape, porosity, density and compositional characteristics"--Abstract.
