Download or read book Preparation Process of Hollow Fiber Uf Membrane written by Qusay F. Abdul Hameed and published by LAP Lambert Academic Publishing. This book was released on 2011-09 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultrafiltration first appeared at the end of the 19th century and was used for a long time as a concentration and purification technique in laboratory preparations. Studies have been carried out to improve the properties of ultrafiltration polymeric membranes; most of them are related to flat sheet membranes prepared by the dry/wet phase inversion process. On the other hand, less researches has been done on the preparation and characterization of hollow fiber membranes. This is due to the fact that the preparation of hollow fiber membranes is much more complex than the former which involves various factors such as the rapid phase inversion kinetics and the interfacial mass transfer during the spinning process, as well as the large number of spinning parameters, for example, the structure and dimension of the spinneret, the flow rate of the bore fluid, the composition and temperature of both the bore fluid and external coagulant, the temperature difference between the dope and quench medium, polymer dope viscosity, the dope extrusion rate, the fiber wind-up speed, the air gap distance, etc. Nowadays hollow fiber membrane configuration is the preferred option in membrane application

This book was released on 2013-03-12 with total page 691 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a record of a symposium, "Ultrafiltration Membranes and Applications," which was held at the l78th National Meeting of the American Chemical Society in Washington, D.C., September 11-13, 1979. In organlzlng these sessions, I hoped to provide a comprehensive survey of the current state of ultrafiltration theory, the most recent advances in membrane technology, and a thorough treatment of existing applications and future directions for ultrafiltration. For me, the symposium was an outstanding success. It was a truly international forum with stimulating presentations and an enthusiastic audience. I hope that some of this spirit has spilled over into this volume, which is intended to reach a much wider audience. I am indebted to the Division of Colloid and Surface Chemistry of the American Chemical Society for their sponsorship. ANTHONY R. COOPER Palo Alto, California }larch, 1980 vii CONTENTS PART I.

Download or read book Uremic Toxins written by Severin Ringoir and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present book contains the Proceedings of a two day Symposium on Uremic Toxins organized at the University of Ghent in Belgium. A series of guest lectures, free communications and posters have been presented. An international audience of 163 scientists from 16 nationalities listened to and discussed extensively a spectrum of topics brought forward by colleagues and researchers who worked for many years in the field of Uremic Toxins. There is a striking contrast between all the new dialysis strategies available in the work to "clean" the uremic patients and the almost non-progression of our knowledge on uremic toxins in the past decade. In this sense the symposium was felt by all participants as a new start for the research in the biochemical field of the definition of uremia. If the present volume would stimulate new work in this field in order to define uremia, or identify the uremic toxins, the purpose of the organizers would be maximally fulfilled.

This book was released on 2007 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: The separation and purification of organic-solvent-based process streams may be carried out by membrane processes such as nanofiltration/ultrafiltration/microfiltration and membrane solvent extraction. Lack of solvent stability and chemical stability of most commercially available membranes is limiting the utilization of the above mentioned membrane technologies. This dissertation was primarily focused on developing solvent resistant hollow fiber and flat film membranes for separation and purification of organic-solvent-based process streams. Available porous polymeric supports (Polypropylene (PP), Polyethersulfone (PES) and Nylon) suitable for the required solvent-stable applications were chosen first and then the supports were modified to satisfy the requirements for the applications. Membrane modification techniques employed were interfacial polymerization (IP) and poly(ethyleneimine) (PEI) self crosslinking. Thin film composite (TFC) nanofiltration and ultrafiltration membranes were fabricated on PBS, Nylon and hydrophilized PP support membranes. Before carrying out IP, PP was hydrophilized by pre-wetting with acetone and treating with hot chromic acid solution. The introduced procedure of "modified IP" involved wetting next with the aqueous monomer solution followed by the organic monomer solution. Nanofiltration membranes were characterized using solutes, safranin 0 (MW 351) and brilliant blue R (MW 826) dyes in methanol; ultrafiltration membranes were characterized with a 70% alcoholic solution of zein (MW 35,000). These membranes were also studied for long term solvent stability in ethanol and toluene. The membrane based on PP was first hydrophilized by the techniques of "modified IP" and PHI self crosslinking. For possible applications in microfiltration of aqueous systems, these hydrophilized membranes were characterized by the water permeation rate. Crosslinking of PHI was implemented on the lumen side of the Nylon hollow fibers to reduce the pore size; then, their performance in membrane solvent back extraction was studied. Extraction of phenol from MIBK into an aqueous caustic solution was studied as a model system for reactive back extraction; extraction of acetic acid from MIBK into water was studied as a model system for nonreactive back extraction. Hollow fibers of PBS were coated on the lumen side by IP. The IP layer was again coated with silicone to make the IP coating impervious to water. The coated PES fibers were then tested for heat transfer performance. All modified membranes were also characterized using scanning electron microscopy. Thin film composite nanofiltration and ultrafiltration membranes were successfully fabricated on PP and PBS hollow fiber supports; high rejections of solutes and high solvent fluxes were achieved in UF and NT membranes. However, only the PP-based TFC membranes retained their characteristics after solvent exposure for the studied period of time. Permanent hydrophilization of PP was achieved by the "modified IP procedure. Reduced pores on the lumen side of Nylon hollow fibers provided stable aqueous-organic interface for solute transport in membrane solvent back extraction; the coating improved the extraction performance of the membranes. Better heat transfer performance was achieved in the coated PBS hollow fibers when compared with the nonporous PP hollow fibers.

Membranes can be manufactured from a range of materials including polymeric compounds, and ceramic materials, and both these materials are considered in the book. There are 5 chapters on water and wastewater membranes that cover the fabrication of thin film (TFC) composite membranes for nanofiltration(NF)/reverse osmosis (RO)/forward osmosis (FO) applications, stimuli responsive membranes, electrospun membranes, porous ceramic membranes, and polymeric ultrafiltration (UF) manufacture and modification. There are another 6 chapters on gas separation that consider carbon membranes, zeolite membranes, silica template and metal oxide silica membranes, TFC membranes, silica membranes, and metal organic framework (MOF) membranes. Zeolite membranes are also considered for organic solvent applications, as are solvent-resistant membranes manufactured by phase inversion, ceramic-supported composite membranes, and ceramic NF membranes. The emerging areas of membranes for energy and biomedical applications have 3 and 2 chapters, respectively. Energy applications consider ion exchange membranes for use in fuel cells, membranes for electrodialysis, and membranes for use in microbial fuel cells. For biomedical applications the chapters focus on hemodialysis membranes and redox responsive membranes.
