Download or read book Coagulation and Flocculation in Water and Wastewater Treatment written by John Bratby and published by IWA Publishing. This book was released on 2006-10-15 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coagulation and Flocculation in Water and Wastewater Treatment provides a comprehensive account of coagulation and flocculation techniques and technologies in a single volume covering theoretical principles to practical applications. Thoroughly revised and updated since the 1st Edition it has been progressively modified and increased in scope to cater for the requirements of practitioners involved with water and wastewater treatment. A thorough gamut of treatment scenarios is attempted, including turbidity, color and organics removal, including the technical aspects of enhanced coagulation. The effects of temperature and ionic content are described as well as the removal of specific substances such as arsenic and phosphorus. Chemical phosphorus removal is dealt with in detail, Rapid mixing for efficient coagulant utilization, and flocculation are dealt with in specific chapters. Water treatment plant waste sludge disposal is dealt with in considerable detail, in an Appendix devoted to this subject. Invaluble for water scientists, engineers and students of this field, Coagulation and Flocculation in Water and Wastewater Treatment is a convenient reference handbook in the form of numerous examples and appended information.

Available in PDF, EPUB and Kindle. Book excerpt: First published in 1993, Coagulation and Flocculation is a practical reference for the researchers in the field of the stabilization and destabilization of fine solid dispersions. By omitting chapters that remained unchanged from the first edition, the editors of this second edition completely update, rewrite, and expand upon all chapters to reflect a decade of the latest advances in both theoretical and application aspects of the field. The authors provide expanded material that includes dissociation from a solid surface with independent sites; improvements to the Gouy-Chapman model; electrical double layer, surface ionization, and surface heterogeneity; thin liquid films and modeling of a semi-batch process using microprocesses probabilities; and clay mineral intracrystalline reactions, applications, and gelation. New chapters cover homopolymers and their effect on colloid stability, including never before published figures and equations; the stability of suspensions in the presence of surfactants, polymers, and mixtures; and the flocculation and dewatering of fine-particle suspensions, emphasizing floc formation, growth, structure, and applications. The second edition of Coagulation and Flocculation effectively captures both the theoretical and application aspects of the latest advances in the evolving field of solid dispersions, suspensions, and mixtures.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Coagulation Kinetics and Structure Formation written by H. Sonntag and published by Springer. This book was released on 1987 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Colloidal dispersions play a very important role in nature, industry, and daily life. Sometimes, long-term stability is observed or desired as in ferrotluids (composed of very small magnetic particles with radii of ~ 10 nm), which must be stable even in external fields. On the other hand, only short-term stable dispersions may be necessary during actual processing operations, for example, dispersions of magnetite particles during tape manufacture. The stability of dispersions and many of their physical properties are related to the interaction between the particles in the dispersion medium, which may contain surfactants or macromolecular species. If the net interparticle interaction forces are attractive, then aggregation may occur. Two general types of aggregation behavior may be distinguished: coagulation and flocculation. These two terms are frequently used synonymously but IUPAC has recommended the following definitions: Coagulation implies formation of compact aggregates, leading to the macroscopic separation. Flocculation implies the formation of a loose or open network, floc, which may or may not separate macroscopically. Flocculation brought about by the simultaneous coadsorption of polymer molecules on two (or more) particles is referred to as bridging flocculation. If coagulation results in the merging of two particles into one, as may occur with liquid droplets in emulsions, this process is referred to as coalescence.

Available in PDF, EPUB and Kindle. Book excerpt: K.J. Ives Professor of Public Health Engineering University College London The aggregation of small particles in liquids, to form flocs which are large enough to settle, or to be filtered, is a common operation in industrial processes, and water and wastewater treatment. This aggregation, given the general title flliocculation in this book, may be brought about by the addition of chemicals to reduce the stability of the original suspension, by neutralising electrical forces of repulsion, by the addition of chemicals (polymers) to link particles by bridging action, by the addition of chemicals which form particles to increase collision proba bilities, and by the input of energy leading to hydrodynamically induced collisions. The particles undergoing flocculation may range from colloidal in the nanometer size range, through micro scopic (micron) size, up to visible particles in the millimeter size range; that is a total size range of six orders of magnitude. Consequently the colloid chemist and the hydrodynamicist are both concerned with the interactions that take place, and to them the engineer must turn, to obtain the fundamental information ne cessary for the process design and its associated hardware.
