Transport Mechanisms in Membrane Separation Processes Book Excerpt:

The present book contains a comparison of existing theoretical models developed in order to describe membrane separation processes. In general, the permeation equations resulting from these models give inaccurate predictions of the mutual effects of the permeants involved, due to the simplifications adopted in their derivation. It is concluded that an optimum description of transport phenomena in tight (diffusion-type) membranes is achieved with the "solution-diffusion" model. According to this model each component of a fluid mixture to be separated dissolves in the membrane and passes through by diffusion in response to its gradient in the chemical potential. A modified Flory-Huggins equation has been derived to calculate the solubility of the permeants in the membrane material. Contrary to the original Flory-Huggins equation, the modified equation accounts for the large effect on solubility of crystallinity and elastic strain of the polymer chains by swelling. The equilibrium sorption of liquids computed with this equation was found to be in good agreement with experimental results. Also, the sorption of gases in both rubbery and glassy polymers could be described quan titatively with the modified Flory-Huggins equation without any need of the arbitrary Langmuir term, as required in the conventional "dual-mode" sorption model. Furthermore, fewer parameters are required than with the at least identical accuracy.

Membrane Process Design Using Residue Curve Maps Book Excerpt:

Design and Synthesis of Membrane Separation Processes provides a novel method of design and synthesis for membrane separation. While the main focus of the book is given to gas separation and pervaporation membranes, the theory has been developed in such a way that it is general and valid for any type of membrane. The method, which uses a graphical technique, allows one to calculate and visualize the change in composition of the retentate (non-permeate) phase. This graphical approach is based on Membrane Residue Curve Maps. One of the strengths of this approach is that it is exactly analogous to the method of Residue Curve Maps that has proved so successful in distillation system synthesis and design.

Membrane Processes in Separation and Purification Book Excerpt:

The current vigour in separations research principally derives from the need for pioneering separations processes in an emerging technology (biotechnology), from new societal emphases (reduction of chemical emissions into the environment), as well as from opportunities for achieving dramatic improvements in the efficiency of a number of manufacturing technologies through the development of a new generation of membranes (novel membrane applications). Accordingly, the contributions to this volume are grouped into `Membranes in Biotechnology' (11 papers), `Membranes in Environmental Technology' (6 papers), and `New Concepts' (4 papers). This is followed by one contribution each on `Energy Requirements' and `Education', i.e. membrane processes within an academic curriculum. The book thus amounts to a state-of-the-art review of applied membrane processes. Even though other texts have appeared in recent years, a more documented, practical book is needed, with a strong interaction with the collateral disciplines of materials sciences, life sciences and environmental science. This book emphasizes the need for such an integrated approach to membrane processes.

Membrane Processing for Dairy Ingredient Separation Book Excerpt:

Membrane processing is a filtration technique in which particles are separated from liquids by being forced through a porous material, or membrane. Applied to dairy products, the separation techniques allow valuable compounds, found in milk, to be isolated for use as ingredients in food processing. A comprehensive overview of membrane separation processes, this book explores various applications such as pressure driven processes, electrical field driven processes, and concentration driven processes, for the recovery of various dairy streams and ingredients. The topics covered place emphasis on new applications, including microfiltration, ultrafiltration, reverse osmosis, electrodialysis, and pervaporation. The text also presents in-depth knowledge of the mechanisms of each membrane separation process, as well as membrane types and the equipment used in these processes.Combining their educational backgrounds and substantial industrial experience in dairy ingredients processes, the authors address cutting-edge technologies that have been thoroughly researched and have great potential to be commercialized in the near future. The book will therefore be of interest to dairy industry professionals and will serve as a source of reference material for professors and students in food science and engineering.

Engineering Aspects of Membrane Separation and Application in Food Processing Book Excerpt:

Engineering Aspects of Membrane Separation and Application in Food Processing presents an overview and introduction to a wide range of membrane processes, their unique characteristics and challenges. In the food industry, as in many industries, membranes have an environmental advantage over conventional processes that they displace, because they are less energy intensive. The processing at near-ambient conditions also retains flavors and nutritional value. These advantages, together with significant reductions in the cost of membrane modules, augers well for their future not only in the dairy industry but in other parts of the food industry, such as alcohol processing, animal product processing, and fruit and vegetable processing. Chapters address a wide range of membranes separations in the food and beverage industries, and applications are provided that will be of value not only to food engineers but also to process engineers working in other areas. The processing of food is now a highly interdisciplinary science, and anyone concerned with food processing will benefit from reading this book and understanding what membrane processes of the twenty-first century have to offer.

Electric Field Enhanced Membrane Separation System Book Excerpt:

The membrane separation process has emerged as a powerful separation technique and has become an integral part of modern process industries. This has found wide applications in the field of biotechnology, beverage, dairy industry, clarification of fruit juice, waste water treatment etc. The advantages of these processes are their unique separation capabilities, low energy consumption, high throughput, and ease of scaling etc., compared to conventional separation processes. However, the application of membrane separation process has been limited by the presence of concentration polarisation and membrane fouling. These lead to decline in permeate flux and change in retention behaviour. Therefore, the ways to reduce concentration polarisation and thereby enhancing the filtration rate are currently active areas of research in view of the increasing demand of membranes application to various industrial separation processes. To minimise the membrane fouling and concentration polarisation, several techniques have been investigated. In this regard, application of external d.c. (direct current) electric field across the membrane is a promising method to reduce concentration polarisation and fouling. This book deals with the relevant principles, technology and the theoretical details involved in this process. It is to be emphasised that no such book dealing with electric field assisted membrane filtration exists currently. Therefore, this book obviously has significant advancement compared to existing books on membrane technology. This book can be used as one of the Texts for the course like "Novel Separation Processes" taught in Postgraduate level. Of course, this book can be an extremely useful reference book for the students and professionals in Chemical and Environmental Engineering. We believe this book will have two fold impacts. Firstly, its academic value is quite high; Secondly, it will have remarkable impact of scaling up such system in actual industrial scale from pilot plant data in an emerging area. Moreover, a book on such a topic does not exist today; the importance of it from an academic point of view is undoubtedly remarkable. This book presents detailed description of the effect of electric field to a number of typical applications, e.g. fruit juice clarification, separation and fractionation of protein solution, micellar enhanced ultra-filtration for dye removal. The results are analysed in full detail.
