Available in PDF, EPUB and Kindle. Book excerpt: This investigation was undertaken with the objective of determining the importance of the initial mixing step in water and wastewater treatment processes and determining whether increasing the rapidity of the initial mixing could improve process performance. The principal process considered was alum coagulation-flocculation of a kaolin suspension in water. the initial mixing device under consideration was a biplane, square-mesh grid of bars placed in a turbulent flow, tubular reactor; a 2-in. pipe was used in the present studies. Studies were made using a single electrode "point" conductivity probe and NaCl solution tracer to determine what parameters affect the mixing which occurs in the turbulent flow field downstream from a grid, and from these results a general mixing model was developed. The relation between initial mixing and process performance was studied by using two of the grids from the mixing studies as initial mixing devices in coagulation of a kaolin suspension.

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.

Book excerpt: Advanced Water Treatment: Electrochemical Methods reviews the current state-of-the-art in the electrochemical-based methods for water treatment, the effectiveness of the electrochemical oxidation technique in inactivating different primary biofilm forming paper mill bacteria, as well as sulfide and organic material in pulp and paper mill wastewater in laboratory-scale batch experiments. Various electrodes are described, including boron-doped diamond, mixed metal oxide, PbO2, and their impacts on inactivation efficiency of parameters, such as current density and initial pH or chloride concentration of synthetic paper machine water. The mechanisms of action of various electrodes in different systems are reported. The book is a source of information for environmental and chemical engineers due to the number of methods and industry-focused application cases and researchers who study the transition from a laboratory environment to practical applications. Includes the most recent research on advanced water treatment by electrochemical methods Describes the use of electrochemical cleaning of paper mill wastewaters Includes techniques for cleaning mining waters and removal of organic pollutants by electrochemical methods

Book excerpt: The present work is devoted to optimization based upon physical and mathematical modelling of calcium treatment processes for low-alloy steel grades in Ladle, using Steel Refining Unit (SRU). The widely applicable method of calcium injection into ladle on Steel Refining Unit by means of Flux-Cored Wire (FCW) or the method of silicocalcium blowing-in often requires significant flow rate of calcium containing alloys to ensure the necessary concentration of calcium and sulfur in the finished steel. Methods of mathematical modelling are widely applied for the purpose of improvement of calcium alloys injection modes into ladle. However, mainly heating processes in the ladle are taken into consideration in this connection; meanwhile hydrodynamic processes are accounted only partially. At the same time, interfacial reactions of the metal with steam bubbles play a significant role in the processes of interaction between calcium and supernatant liquid, whereby sulfur and oxygen that are dissolved in steel take part in the reactions described above. Nevertheless, only single quantitative estimates are known for kinetics of mass exchanging processes in the ladle. Finally, efficiency of calcium treatment depends on chemical composition of steel. Probability of low-melting calcium aluminates formation, which ensure improvement of pouring capacity, depends not only on the frequently used proportion of [Ca] to [Al], but also on conditions of steel oxidation and sulfur content in the steel. Therefore, optimization of injection modes for calcium containing alloys based on the thermodynamic and kinetic analysis of steel deoxidation and modification conditions, as well as on the mathematical modelling of mass exchanging processes, represents a crucial scientific and technical challenge of nowadays.
