Available in PDF, EPUB and Kindle. Book excerpt: Th i s book had its orl gl n in the sympos i urn on "Polymers for Desalination" sponsored by the Division of Polymer Chemistry of the American Chemical Society and held in September, 1971 in Wash ington D. C. at the 162nd national meeting of the Society. However, the book is not simply the proceedings of that symposium. A num ber of additional papers were contributed by other workers in the field, and the original papers presented at the symposium have, for the most part, been expanded. The book thus represents a broad cross section of membrane research and development activities in the United States and abroad within the field of reverse osmosis. The purposes of the book are to bring attention to important new developments in this field, to suggest what the next generation of reverse osmosis equipment may look like, and to indicate where fur ther research and development are needed. The vast majority of the papers collected here represent work supported by the Office of Saline Water of the United States Department of the Interior, and the emphasis here is clearly on the application of the reverse os mosis process to water purification. However, many of the concepts, methods, and conclusions are expected to be useful in other areas of membrane science and technology.

Download or read book Phase-Field Modeling of the Polymer Membrane Formation Process for Micro- and Ultra-Filtration written by Michael Rosario Cervellere and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Porous polymer membrane filters are widely used in separation and filtration process. Micro- and ultra-filtration membranes are commonly used in biopharmaceutical applications such as filtering viruses and separating proteins from a carrier solution. The formation of these membrane filters via phase inversion is a complex and interconnected process where varying casting conditions can have a wide variety of effects on the final membrane morphol- ogy. Tailoring membrane filters for specific performance characteristics is a tedious and time consuming process. The time and length scales of membrane formation make it extremely difficult to experimentally observe membrane formation. Modeling the membrane formation process allows one to slow down time and closely observe the formation of complex pore net- works. This allows new understanding and visual representations of the effects of different casting conditions and the resulting pore networks that form. This dissertation presents two separate models for two different membrane formation processes - thermally induced phase separation (TIPS) and non-solvent induced phase sepa- ration (NIPS). The Phase-Field method is employed to model the mesoscopic morphological structures that emerge during membrane formation. The Cahn-Hilliard equation is used to capture the diffusive nature of membrane formation and the Flory-Huggins free energy of mixing describes the thermodynamic equilibriums of the polymer solutions. Large-scale two- and three-dimensional simulations are used for capturing the resulting pore morphology under various casting conditions. The model for TIPS evaluated different casting conditions for the membrane forming system PVDF/DPC (polyvinylidene fluoride/diphenyl carbonate). The effects of casting surface temperature, thermal conductivity, quench rate, and polymer concentration were in- vestigated. Isotropic thermal quenches were used to analyzed pore size and interconnectivity while varying the quench rate and polymer concentration. Anisotropic thermal quenches in which a constant temperature cooling surface is imposed at the top surface were used to an-alyze the pore size and formation of a dense pore region near the casting surface. Different polymer concentrations, casting surface temperatures, and polymer thermal conductivities were used to characterize their effects on pore morphology. The formation of a dense pore region occurs near the top surface and the thickness of this dense pore region is dependent on the previous mentioned casting conditions. The model for NIPS evaluated the effects of coagulation bath composition and polymer concentration on final membrane morphology for PES/NMP/Water (polyethersulfone/n- methyl-2-pyrrolidone/water). These simulations were then compared to handcast mem- branes of a similar membrane forming system for comparison the simulated structures. The NIPS model evaluated coagulation bath composition and polymer concentration and the resulting morphologies. Two and three dimensional simulations were used to look at cross section and top surface morphology respectively. The concentration of NMP in the co- agulation bath was varied to verify the predictive capabilities of the model. The resulting simulations of cross sections and top surfaces had good agreement with handcast membranes when NMP is added to the coagulation bath.

Available in PDF, EPUB and Kindle. Book excerpt: The last two decades have seen a phenomenal growth of the field of genetic or biochemical engineering and have witnessed the development and ultimately marketing of a variety of products-typically through the manipulation and growth of different types of microorganisms, followed by the recovery and purification of the associated products. The engineers and biotechnologists who are involved in the full-scale process design of such facilities must be familiar with the variety of unit operations and equipment and the applicable regulatory requirements. This book describes current commercial practice and will be useful to those engineers working in this field in the design, construction and operation of pharmaceutical and biotechnology plants. It will be of help to the chemical or pharmaceutical engineer who is developing a plant design and who faces issues such as: Should the process be batch or continuous or a combination of batch and continuous? How should the optimum process design be developed? Should one employ a new revolutionary separation which could be potentially difficult to validate or use accepted technology which involves less risk? Should the process be run with ingredients formulated from water for injection, deionized water, or even filtered tap water? Should any of the separations be run in cold rooms or in glycol jacketed lines to minimize microbial growth where sterilization is not possible? Should the process equipment and lines be designed to be sterilized in-place, cleaned-in-place, or should every piece be broken down, cleaned and autoclaved after every turn?

Download or read book Polymer Solutions written by Iwao Teraoka and published by John Wiley & Sons. This book was released on 2004-04-07 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymer Solutions: An Introduction to Physical Properties offers a fresh, inclusive approach to teaching the fundamentals of physical polymer science. Students, instructors, and professionals in polymer chemistry, analytical chemistry, organic chemistry, engineering, materials, and textiles will find Iwao Teraoka’s text at once accessible and highly detailed in its treatment of the properties of polymers in the solution phase. Teraoka’s purpose in writing Polymer Solutions is twofold: to familiarize the advanced undergraduate and beginning graduate student with basic concepts, theories, models, and experimental techniques for polymer solutions; and to provide a reference for researchers working in the area of polymer solutions as well as those in charge of chromatographic characterization of polymers. The author’s incorporation of recent advances in the instrumentation of size-exclusion chromatography, the method by which polymers are analyzed, renders the text particularly topical. Subjects discussed include: Real, ideal, Gaussian, semirigid, and branched polymer chains Polymer solutions and thermodynamics Static light scattering of a polymer solution Dynamic light scattering and diffusion of polymers Dynamics of dilute and semidilute polymer solutions Study questions at the end of each chapter not only provide students with the opportunity to test their understanding, but also introduce topics relevant to polymer solutions not included in the main text. With over 250 geometrical model diagrams, Polymer Solutions is a necessary reference for students and for scientists pursuing a broader understanding of polymers.

Download or read book Physics of Biological Membranes written by Patricia Bassereau and published by Springer. This book was released on 2018-12-30 with total page 616 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book mainly focuses on key aspects of biomembranes that have emerged over the past 15 years. It covers static and dynamic descriptions, as well as modeling for membrane organization and shape at the local and global (at the cell level) scale. It also discusses several new developments in non-equilibrium aspects that have not yet been covered elsewhere. Biological membranes are the seat of interactions between cells and the rest of the world, and internally, they are at the core of complex dynamic reorganizations and chemical reactions. Despite the long tradition of membrane research in biophysics, the physics of cell membranes as well as of biomimetic or synthetic membranes is a rapidly developing field. Though successful books have already been published on this topic over the past decades, none include the most recent advances. Additionally, in this domain, the traditional distinction between biological and physical approaches tends to blur. This book gathers the most recent advances in this area, and will benefit biologists and physicists alike.
