This book was released on 2016-04-15 with total page 538 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 this new edition has been progressively modified and increased in scope to cater for the requirements of practitioners involved with water and wastewater treatment. New topics in this new edition include : • activated sludge bulking and foaming control and enhanced bioflocculation; • algae removal and harvesting; • dissolved organic nitrogen (DON) removal; • inorganics removal; • turbidity and its measurement; • wastewater treatment by coagulation and chemically enhanced primary treatment (CEPT). The book presents the subject logically and sequentially from theoretical principles to practical applications. Successive chapters deal with, in turn, properties of materials present in waters and wastewaters; characteristics and types of coagulants commonly in use; mechanisms and practical implications of destabilization of waterborne material using metal coagulants and polyelectrolytes; considerations and requirements for coagulant addition at the rapid mixing stage; theoretical and practical considerations of flocculation; and details of experimental procedures for assessing primary coagulants, flocculant aids, sludge conditioners, and flocculation parameters. Numerous examples are included as appropriate. Treatment and disposal of sludges resulting from coagulation-flocculation related operations is dealt with in an Appendix. This important topic has been separated from the main text to avoid disturbing the continuum of the presentation. Coagulation and Flocculation in Water and Wastewater Treatment is a readable and useful resource for the water scientist and engineer. It is a convenient reference handbook providing numerous examples and appended information and it is a vital text for course material for undergraduate and postgraduate students.

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.

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 Flocs in Water Treatment written by David H. Bache and published by IWA Publishing. This book was released on 2007-11-08 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flocs in Water Treatment is the first of its kind - serving as a valuable aide-mémoire for scientists, process engineers and other professionals engaged in water treatment. The framework described in Flocs in Water Treatment can also be applied to aggregated solids found both in the natural environment, and within a broad range of industries. Flocs (aggregated solid matter) resulting from the combined influence of coagulation and flocculation play a vital role in solid-liquid separation processes. The design and operation of water treatment plants demands a proper understanding of the ways in which flocs affect treatment systems and how their properties can be manipulated to increase treatment efficiency. Flocs in Water Treatment provides a comprehensive account of the ways in which flocs are formed, their characterization, and how they behave in practice. Flocs are complex entities, whose properties defy easy description and measurement. In spite of this, the authors provide a clear and discerning account of the current state of knowledge; this is rooted in science and draws on many disciplines. Based on their experiences in research and the workings of full scale treatment plants, the authors offer candid advice on tasks such as the measurement of floc properties and guidance on problems involving the use of chemicals for controlling floc properties within treatment systems.

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.
