Book Trace Organic Removal by Nanofiltration and Reverse Osmosis Processes

Download or read book Trace Organic Removal by Nanofiltration and Reverse Osmosis Processes written by Long Nghiem and published by LAP Lambert Academic Publishing. This book was released on 2010-06 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph delineates the retention mechanisms of emerging trace organic contaminants by several nanofiltration (NF) and reverse osmosis membranes. Retention of neutral trace organics by a tight NF or RO membrane is dominated by steric (size) exclusion, whereas both electrostatic repulsion and steric exclusion govern the retention of negatively charged trace organics by a loose NF membrane. Speciation of trace organics may lead to a dramatic change in retention as a function of pH, with much greater retention observed for ionized, negatively charged trace organics. Retention of the negatively charged trace organics decreases as the solution's ionic strength increases due to charge shielding and double layer compression. For uncharged trace organic species, intrinsic physicochemical properties of the trace organic molecules can substantially affect their retention. This monograph also critically demonstrates the possible complexity of a real membrane filtration system where trace organic contaminants are of concern. Factors such as operating conditions and feed solution composition can influence the filtration of trace organics.

Book Membrane Separations Technology

Download or read book Membrane Separations Technology written by R.D. Noble and published by Elsevier. This book was released on 1995-01-17 with total page 737 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of membrane separation technology is presently in a state of rapid growth and innovation. Many different membrane separation processes have been developed during the past half century and new processes are constantly emerging from academic, industrial, and governmental laboratories. While new membrane separation processes are being conceived with remarkable frequency, existing processes are also being constantly improved in order to enhance their economic competitiveness. Significant improvements are currently being made in many aspects of membrane separation technology: in the development of new membrane materials with higher selectivity and/or permeability, in the fabrication methods for high-flux asymmetric or composite membranes, in membrane module construction and in process design. Membrane separation technology is presently being used in an impressive variety of applications and has generated businesses totalling over one billion U.S. dollars annually.The main objective of this book is to present the principles and applications of a variety of membrane separation processes from the unique perspectives of investigators who have made important contributions to their fields. Another objective is to provide the reader with an authoritative resource on various aspects of this rapidly growing technology. The text can be used by someone who wishes to learn about a general area of application as well as by the knowledgeable person seeking more detailed information.

Book Removal of Volatile Organic Compounds from Contaminated Groundwater by Pervaporation

Download or read book Removal of Volatile Organic Compounds from Contaminated Groundwater by Pervaporation written by Sukla Chandra and published by . This book was released on 1996 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effective removal of non-aqueous phase liquid pools in groundwater and volatile organic compounds (VOCs) from contaminated soils can be achieved by surfactant flushing. This surfactant-rich ground water contains VOCs like trichloroethylene (TCE), dichloroethylene (DCE), etc. Membrane pervaporation technique is employed here to remove TCE from these micellar systems where a very high percentage of the VOC is trapped inside the micellar core. The micellar solution flows through the bore of microporous hydrophobic hollow fibers wherein the micelles break down and release the surfactants and the TCE. The TCE is then removed through the pores and a nonporous thin silicone skin on the outside surface of the fiber, the other side of which is subjected to vacuum to allow pervaporation-based removal of the VOC. This research has characterized such a process for removal of TCE with or without surfactant. It was established that the presence of surfactant adversely affected the removal of TCE. The flux of TCE was found to be an increasing function of feed flow rate and Reynolds number. This research has also briefly explored the permeation of nonvolatile hydrocarbons such as dodecane from water flowing through the fiber bore by using a similar hollow fiber membrane.

Book Membrane Processes in Separation and Purification

Download or read book Membrane Processes in Separation and Purification written by J.G. Crespo and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chapters of this book are based upon lectures presented at the NATO Advanced Study Institute on Membrane Processes in Separation and Purification (March 21 - April 2, 1993, Curia, Portugal), organized as a successor and update to a similar Institute that took place 10 years ago (p.M.Bungay, H.K. Lonsdale, M.N. de Pinho (Eds.): Synthetic Membranes: Science, Engineering and Applications, NATO ASI Series, Reidel, Dordrecht, 1986). The decade between the two NATO Institutes witnesses the transition from individually researched membrane processes to an applied and established membrane separation technology, as is reflected by the contents of the corresponding proceeding volumes. By and large, the first volume presents itself as a textbook on membrane processes, still valid, while the present volume focuses on areas of separation need as amenable to membrane processing: Biotechnology and Environmental Technology. 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 of applied membrane processing and may well augment the more fundamental approach of its predecessor.
