Membrane processes are increasingly used in pharmaceutical and biochemical engineering and biotechnology for concentration and purification, synthesis of molecules and drug delivery systems, and support for biochemical reactions. This book provides a state-of-the art overview of the classical membrane processes used in pharmaceutical and biochemical engineering and biotechnology, such as ultrafiltration, microfiltration, virus filtration, membrane chromatography, membrane emulsification, liquid membranes and membrane bioreactors. It describes the general rules (principles, choice of configurations, membranes, parameters, etc.), recent developments (fouling control, increase permeate flux and selectivity, etc.), applications, and theoretical descriptions. Further, it presents emerging processes such as solvent resistant nanofiltration and membrane crystallization. - Presents classical membrane processes such as ultrafiltration, microfiltration, virus filtration, membrane chromatography, membrane emulsification, liquid membranes and membrane bioreactors - Presents emerging processes such as solvent resistant nanofiltration and membrane crystallization - Gives a complete description of each technique (principles, membrane materials and devices, fouling control, and theoretical description) - Contains numerous examples of applications - Includes a uniform notation throughout the book enhancing the presentation and understanding of the content - Includes extensive list of references

During the past two decades Membrane Science and Technology has made tremendous progress and has changed from a simple laboratory tool to large scale processes with numerous applications in Medicine and Industry. In this volume are collected papers presented at the First Europe Japan Congress on Membrane and Membrane processes, held in Stresa in June 1984. Other contributions to the Conference will be published in a special issue of the Journal of Membrane Science. This Conference was organized by the European Society of Membrane Science and Technology and the Membrane Society of Japan, to bring together European Scientists and Engineers face to face with their colleagues from Japan; in both countries membrane processes will play a strategic role in many industrial areas in the 1990s, as predicted by the Japanese project for Next Generation Industries and by the EEC Project on Basic Techno logical Research (BRITE). The large number of participants, of about four hundred from twenty six countries including USA, Australia, China and Brazil, the quality of the Plenary Lectures and Scientific Communications made the Conference a significant international success.

Synthetic Membranes and Membrane Separation Processes addresses both fundamental and practical aspects of the subject. Topics discussed in the book cover major industrial membrane separation processes, including reverse osmosis, ultrafiltration, microfiltration, membrane gas and vapor separation, and pervaporation. Membrane materials, membrane preparation, membrane structure, membrane transport, membrane module and separation design, and applications are discussed for each separation process. Many problem-solving examples are included to help readers understand the fundamental concepts of the theory behind the processes. The book will benefit practitioners and students in chemical engineering, environmental engineering, and materials science.

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

The book Modeling in Membranes and Membrane-Based Processes is based on the idea of developing a reference which will cover most relevant and “state-of-the-art” approaches in membrane modeling. This book explores almost every major aspect of modeling and the techniques applied in membrane separation studies and applications. This includes first principle-based models, thermodynamics models, computational fluid dynamics simulations, molecular dynamics simulations, and artificial intelligence-based modeling for membrane separation processes. These models have been discussed in light of various applications ranging from desalination to gas separation. In addition, this breakthrough new volume covers the fundamentals of polymer membrane pore formation mechanisms, covering not only a wide range of modeling techniques, but also has various facets of membrane-based applications. Thus, this book can be an excellent source for a holistic perspective on membranes in general, as well as a comprehensive and valuable reference work. Whether a veteran engineer in the field or lab or a student in chemical or process engineering, this latest volume in the “Advances in Membrane Processes” is a must-have, along with the first book in the series, Membrane Processes, also available from Wiley-Scrivener.
