This book presents novel techniques to evaluate electrodialysis processes, to synthesize ionic membranes and to characterize their properties. It shows the potential use of membrane process to the treatment of effluents generated in many industrial sectors such as refineries, leather industries, mining and electroplating processes. The book is based on the results obtained by the author's research group during the past decade. It is useful for students, researchers and engineers interested in membrane technologies for water reuse.
The field of membrane separation technology is presently in a state of rapid growth and innovation. Many different membrane separation processes have been developed during the past half century and new processes are constantly emerging from academic, industrial, and governmental laboratories. While new membrane separation processes are being conceived with remarkable frequency, existing processes are also being constantly improved in order to enhance their economic competitiveness. Significant improvements are currently being made in many aspects of membrane separation technology: in the development of new membrane materials with higher selectivity and/or permeability, in the fabrication methods for high-flux asymmetric or composite membranes, in membrane module construction and in process design. Membrane separation technology is presently being used in an impressive variety of applications and has generated businesses totalling over one billion U.S. dollars annually. The main objective of this book is to present the principles and applications of a variety of membrane separation processes from the unique perspectives of investigators who have made important contributions to their fields. Another objective is to provide the reader with an authoritative resource on various aspects of this rapidly growing technology. The text can be used by someone who wishes to learn about a general area of application as well as by the knowledgeable person seeking more detailed information.
This manual provides information on electrodialysis and electrodialysis reversal technologies in water treatment. This clearly written manual explains principles of operation, applications for water treatment, equipment, system design, costs, pretreatment and posttreatment, installation, operation, maintenance, and disposal of concentrate.
Principles of Desalination, Part A, Second Edition is a collection of papers that describes the design of distillation and dual-purpose plants, what desalination can and cannot accomplish in an economical way. One paper discusses techniques toward a rapid and direct way of optimizing the economic performance of sea water conversion systems, incurring capital and continuing costs of operation (for example, transformer equipment, filtration devices, and chemical preparation). Another paper considers the general system and internal system engineering of distillation. Designing distilling plants involves the selection of process parameters, cycle determination, and calculation of water costs. The different types of evaporators are the boiling-type, the flash type, the vapor compression, the combination plant cycles, and the power plant make-up evaporators. Commercial sea water desalination plants incorporate multistage flash evaporators or multieffect vertical-tube or horizontal-tube evaporators. The problem of energy supply to these plants can be solved by a combined generation of electricity and low pressure steam. When the generation of electricity and low pressure steam are combined, the extra fuel demand for electricity generation over the fuel demand for low pressure steam generation only, is less than that for electricity generation alone. This book is suitable for economists, environmentalists, ecologists, and policy makers involved in energy conservation, agricultural development, and water management.
Today, membranes and membrane processes are used as efficient tools for the separation of liquid mixtures or gases in the chemical and biomedical industry, in water desalination and wastewater purification. Despite the fact that various membrane processes, like reverse osmosis, are described in great detail in a number of books, processes involving ion-exchange membranes are only described in a fragmented way in scientific journals and patents; even though large industrial applications, like electrodialysis, have been around for over half a century. Therefore, this book is emphasizing on the most relevant aspects of ion-exchange membranes. This book provides a comprehensive overview of ion-exchange membrane separation processes covering the fundamentals as well as recent developments of the different products and processes and their applications. The audience for this book is heterogeneous, as it includes plant managers and process engineers as well as research scientists and graduate students. The separate chapters are based on different topics. The first chapter describes the relevant Electromembrane processes in a general overview. The second chapter explains thermodynamic and physicochemical fundamentals. The third chapter gives information about ion-exchange membrane preparation techniques, while the fourth and fifth chapter discusses the processes as unit operations giving examples for the design of specific plants. First work on the principles and applications of electrodialysis and related separation processes Presently no other comprehensive work that can serve as both reference work and text book is available Book is suited for teaching students and as source for detailed information
