While new developments in genomics, nanotechnology, sampling, and modelling permit increasingly revealing investigation into flocculation structure and processes, there is still a fundamental lack of knowledge related to many aspects of this phenomenon. Presented by a prominent team of international experts, this text takes a unique perspective and melds together the natural and engineering fields of science as they relate to this central phenomenon. In doing so, the authors present the full range of sampling, handling, analytical, and interpretive options for operational management of natural or engineered system, providing comprehensive coverage that meets the needs of researchers, practitioners and students.
