Coagulation and Flocculation: Theory and Applications
CRC Press, Jan 19, 1993 - Science - 720 pages
This volume details the thermodynamics and kinetics of the adsorption of surfactants and polymers on solids, as well as coagulation and flocculation mechanisms - demonstrating the applicability of the newest theoretical approaches on practical systems.;Written by over 15 international experts in the field, Coagulation and Flocculation: treats the Gouy-Chapman theory of an isolated planar charged surface and the DLVO theory describing the interaction between two identical charged surfaces; shows which energies are responsible for structure formation, what types of structure can be built in diluted and concentrated systems and how such structures can be studied and characterized; describes the interplay between interface and hydrodynamic forces and derives equations for calculating their individual probabilities; examines the use of microscopy, photography, individual particle sensors, sedimentation and light scattering to measure aggregate size distributions; and discusses methods for forming ceramics and the effects of improvements in powder packing and the stabilization of powder suspensions on processing steps.
