Book Description :

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

Book Description :

Industrial application of ion exchange membranes started from saline water desalination. However, now it extends widely in many fields such as drinking water or wastewater treatment, demineralisation of amino acid, whey, sugar liquor, recovery of useful components, treatment of organic substances and contributes to the improvement of our standard of living. The application of ion exchange membranes must expand further if we pay attention to unique functions of the membranes for separating ionic species from non-ionic substances or other kinds of ionic species. This book discusses the performance of an electrodialyser from the stand point of fundamental and practical views.

Book Description :

Ion exchange membranes serve as the selective barrier in (electro-)dialytic separation processes. To date they are applied almost exclusively to aqueous electrolyte systems. In principal, however, ion exchange membranes also should be applicable to non aqueous solutions. In order to clarify how and why the membrane behavior in non aqueous electrolyte systems deviates from aqueous systems, equilibrium and transport properties of commercial monopolar and bipolar membranes are determined experimentally for aqueous, methanolic and ethanolic sodium perchlorate solutions in this study. Based on these results the dependence of the membrane performance on solution characteristics such as the relative permittivity, the solute concentration and the ionic mobility and on membrane specifics such as the type of functional groups and the membrane morphology is discussed. Thus, evidence is found for the importance of ion pair formation in the solution as well as in the membrane phase. Both effects lead to a more or less pronounced degradation of the membrane performance. Further insights into the stationary and dynamic behavior of ion exchange membranes is obtained from a detailed, physically meaningful and dynamic bipolar membrane model. It is characterized by the consideration of four ionic species as well as solvent and electric potential, the existence of a space charge region at the cation/anion exchange layer interface, the description of non-idealities by means of solution and membrane phase activity coefficients and the solvent dissociation according to the chemical reaction model. Thus, a model is developed which is able to reproduce all observed experimental trends for both aqueous and non aqueous solutions.

Book Description :

Due to their ability to selectively transport charged species (e.g., ions), ion exchange membranes (IEMs) are required for efficient operation of various membrane-based technologies for producing clean water and energy. Examples include electrodialysis, reverse electrodialysis, and fuel cells, among others. IEMs are also actively explored for use in processes that have not traditionally used them (e.g., reverse osmosis, forward osmosis, batteries, etc.). A molecular understanding of the relationship between polymer structure and water/ion transport properties could lead to new strategies for rational design of high performance membranes, improving efficiencies of membrane-based technologies and catalyzing their use in novel applications. However, despite the sustained relevance of ion exchange membranes, such molecular level understanding remains largely incomplete. This study is aimed at elucidating the main factors governing ion transport in ion exchange membranes. Fundamental models for equilibrium ion sorption and concentration gradient driven ion transport (i.e., salt permeability coefficients) in IEMs were developed using ideas from the polyelectrolyte literature (i.e., Manning’s counter-ion condensation theory). The framework presented in this dissertation accurately predicted, for the first time to the best of our knowledge, experimental equilibrium ion sorption and salt permeability results in a series of commercial IEMs with no adjustable parameters. The modeling results were used to establish a connection between polymer structure and ion transport properties. The influence of fixed charge group concentration on equilibrium ion sorption in IEMs was also investigated. A series of cation and anion exchange membranes having different fixed charge group concentrations but similar water content were synthesized. Equilibrium membrane ion concentrations were experimentally measured. Co-ion sorption in the membranes decreased with increasing fixed charge group concentration, presumably due to enhanced Donnan exclusion. However, the extent of co-ion sorption decrease in the cation exchange membranes was greater than that in the anion exchange membranes, despite similar changes in fixed charge group concentration, presumably due to polymerization induced phase separation in the cation exchange membranes. The experimental ion sorption data were interpreted within the framework of the ion sorption model presented in this study, and relations between membrane properties and equilibrium ion sorption in such materials were developed.

Book Description :

While ion-exchange processes were originally used for the treatment of very dilute solutions, many applications for the treatment of concentrated solu tions have been developed in recent years. In these situations, the mass transfer bottlenecks are located in the~, rather than the liquid phase. Therefore, the development of quantitative models for ion-exchange kinetics requires knowledge about the conductance characteristics of ions and solvent in the solid phase. A useful approach towards this aim is the study of trans port characteristics of these species, and of their interactions in solid ion exchange membranes. Many different transport processes and related phenomena can be observed in membrane-solution systems, e.g., ion migration, electroosmosis, diffusion arid self-diffusion, osmosis, hydraulic flow, hyperfiltration (reverse osmosis) or ultrafiltration, streaming potential and streaming current, and membrane potentials (also called "membrane concentration potentials"). It is important to correlate all these phenomena so as to avoid a very large number of unnec essary measurements. Such correlation is often possible [Meares, 1976] since all these phenomena are determined by the ease of migration of the different species across the membrane. Important correlations have been made and summar ized even before high-capacity ion-exchange membranes became commercially available [Sollner, 1950, 197iJ.
