Available in PDF, EPUB and Kindle. Book excerpt: 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

Available in PDF, EPUB and Kindle. Book excerpt: Physicochemical Hydrodynamics: An Introduction aims to provide an introduction to physicochemical hydrodynamics (PCH), which deals with the interaction between fluid flow and physical, chemical, and biochemical processes. PCH has applications in many areas of science and technology and is a rapidly expanding field. Emphasis of this book is on rational theory and its consequences, with the purpose of showing the underlying unity of PCH, in which diverse phenomena can be described in physically and mathematically similar ways. The magic of this unity is shown in the similar manner in which solutes concentrate in a flow containing chemically reacting surfaces, reverse osmosis membranes, and electrodialysis membranes or the similarity of particle motions in sedimentation, centrifugation, ultrafiltration, and electrophoresis. Problems are included at the end of each chapter and are ordered following the sequence in which the material is set out. The questions range in difficulty, with most requiring an analytic development, but with some asking only for a descriptive answer. All problems are intended to illustrate the ideas presented, though often the solution goes beyond the explicit discussion in the book, with the answer constituting a generalization or extension of the text material. This book is an essential source of information for students majoring in the field of PCH.

This book was released on 2021-12-31 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of ion-exchange membranes (IEMs) has accelerated over the past two decades in a wide variety of industrial processes (electrodialysis, electro-electrodialysis, electrolysis, dialysis, etc.) for applications related to chemical, pharmaceutical and food industries, energy production, water treatments, etc. Organic and mineral fouling (or scaling) phenomena are two major factors limiting the efficiencies of IEMs processes and performances (reduction of the IEMs selectivity and stability, increase of their electrical resistance, deduction of the energy efficiency of the process, etc.) leading to significant economic losses. The current washing, cleaning and sterilization processes (anti-fouling treatments) make it possible to recover some of the IEMs performances, but frequently induce degradation on the membrane material. Another essential point in the fouling studies is the choice of the best and appropriate analysis and diagnostic technique to evaluate this or that magnitude, or observe this or that object on the surface or in the mass of the membrane. This book is focused on recent advancements in techniques for diagnosing and characterizing the fouling effects on membranes, in mechanisms governing this complex phenomenon, and in the various innovative and economically viable solutions for reducing fouling.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Nonlinear Ion Concentration Polarization written by Rhokyun Kwak and published by . This book was released on 2013 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ion exchange membrane (IEM) is a functional material that has a permselectivity of ions. Two types of IEMs - anion exchange membrane (AEM) and cation exchange membrane (CEM) - are used in a variety of electrochemical systems. Ion concentration polarization (ICP) is an ion transport phenomenon that occurs when ions selectively pass through IEMs. Recently, ICP has drawn renewed attention from physicists and engineers, due to its importance in understanding various electrochemical processes for biosensing, desalination, and energy devices. One of the significant scientific issues in ICP is the source of overlimiting conductance (OLC); even after the diffusion-limited current is achieved and nearly all ions are rejected from the IEM (reaching the so-called 'limiting current'), the current starts to increase again at a sufficiently high bias voltage. This nonlinearity of ICP has been extensively studied, but the complexity of this multiscale, multiphysic phenomenon makes it challenging to a fully-detailed picture. My Ph.D thesis is focused at the fundamental understanding and new engineering applications of nonlinear ICP. In this thesis, we consider four subjects: i) visualization of nonlinear ICP and its effects in electrodialysis (ED), ii) electroconvection (EC) as a source of OLC and its behaviors under shear flow, iii) study of water desalination process by ICP and its performance compared with ED, and iv) development of high-throughput, continuous-flow bio-agent preconcentrator by ICP. First, we describe the microscale ED model system for studying nonlinear ICP, which is used for visualizing in situ fluid flows and concentration profiles near IEMs. We verify that the nonlinear ICP largely determines ion transport in ED system. Interesting trends and insights are revealed, which will help in clarifying scientific issues regarding ED operation and improving the efficiency. Second, with this ability to visualize ICP, we firmly establish EC as the mechanism for OLC in the realistic ED system; EC exists near the both IEMs of standard ED systems, and it enhances ion flux through the membranes. We also characterize EC under shear flow by both experiments and numerical modeling. To the best of our knowledge, this characterization is the first to show the unique behaviors of sheared EC: unidirectional vortex structure, its height selection, and vortex advection. Next, based on understandings on sheared EC, we develop robust ICP desalination platform for more scalable (portable) and efficient device to remove salt ions. Utilizing nonlinear ICP between two identical IEMs, we can relocate salt ions along a specific portion of fluidic channels, generating brine and desalted flows in one channel. The salt removal ratio in this ICP desalination platform can be predicted by calculating the sheared EC's height. Also, we reveal the additional effects of nonlinear ICP on desalination process, which is quantified here for the first time, by comparison of salt removal ratio, energy consumption, and current efficiency between ICP platform with CEMs, AEMs, and ED system. In overlimiting regime, one achieves higher (lower) current efficiency compared with ED, when the mobility of relocating ions (e.g. anion at CEMs) is higher (lower) than that of conducting ions (e.g. cation at CEMs). Last, we present a new application utilizing nonlinear ICP, i.e. continuous-flow bio-agent preconcentrator. By controlling the nonlinear ICP region with a pressure gradient against the electric field, we concentrate variously charged bio-agents (e.g., positively / negatively-charged proteins, bacteria, and cells) on the ICP boundary, and collect these pre-concentrated targets in a continuous-flow manner.

Book excerpt: This is one of the first texts in which electro-diffusion of ions in its different aspects is considered as a unified subject. As a subject it is relevant to understanding the behavior of apparently different physical objects such as electrolyte solution, ion-exchangers, ion-selective membranes, and semiconductors. This text treats a selection of topics in electro-diffusion of ions in an aqueous medium --- a nonlinear transport process whose essence is diffusion of ions combined with their migration in a selfconsistent electric field. Electro-Diffusion of Ions is intended to enhance the understanding of particular electro-diffusional transport phenomena and to spark the interest of the mathematical community in the corresponding area of applications and development of a unified scientific vision. Contains some previously unpublished results for electro-diffusional problems.
