This book serves as an introduction on mass transfer models in membrane processes, with a special focus on their applications in Artificial Organs. Various such models are discussed while multiple easy to use module equations are presented, enabling readers to gain basic knowledge of the mass flow of toxins across membranes. This is particularly interesting to membrane manufacturers who may use these equations to improve the relation of module performances and production costs. Additionally, examples which specialize on artificial organs, but in principle can be applied to analogous environmental, food and biotechnology processes- are analysed. This book will appeal to readers who want to understand how membrane modules and processes can be optimized and will be a great tool for graduates, researchers and professionals working in this field.

Manfred Raff spent his professional life focusing on membrane technology. He started his career with a project at Stuttgart University working on improving dialysis monitors. His PhD-thesis dealt with the video screening of electropherograms of proteins in plasma and cerebrospinal fluid, using different electrophoretic separation techniques with different kinds of membranes. His industrial experience began with the development and production of plasmafilters and continued with improving membranes and modules for hemodialysis and oxygenation. After 10 years in industry he received an appointment as a professor at Furtwangen University, teaching courses specializing on thermal and mechanical process engineering and on membrane technology. During his research career -and always in collaboration with industry- Prof Raff investigated multiple topics focusing on measuring the pore size distributions of ultrafiltration membranes, studies of mass transfer in highflux-hemodialysis, artificial liver, blood oxygenation and plasmapheresis. After retiring, he continued working as a guest lecturer for Artificial Organs at different universities.
