This book was released on 2001 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The performance of spiral-wound nanofiltration (NF) and ultrafiltration (UF) membranes was investigated in terms of natural organic matter (NOM) rejection and associated NOM fouling. This study focused on (1) demonstrating the effects of both hydrophobic and electrostatic interactions between NOM components and the membrane surface, (2) determining influential factors (water quality and operational) in NOM rejection and flux decline, (3) determining major foulant components of NOM, and (4) developing NOM-rejection prediction equations and flux-decline (NOM adsorption) models." -- Executive summary.

Download or read book Membrane Technology in Water Treatment in the Mediterranean Region written by Antonia Lorenzo and published by IWA Publishing. This book was released on 2010-11-24 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: The complex dimensions of the Mediterranean freshwater resources, their fragility and their scarcity have been highlighted and have received considerable attention as a primary priority issue politically, technically and scientifically. Membrane technology, with its different applications in water treatment (desalination, potable water treatment, wastewater treatment and reuse) has showed to be a powerful tool to abate the water crisis in the Mediterranean region. The primary objective of Membrane Technology in Water Treatment in the Mediterranean Region is to support the current research and development activities in membrane technology focused on water treatment in the Mediterranean area, providing an international stage to local research organisations and universities devoted to the development of membrane technologies in the following areas: municipal and industrial wastewater treatment, surface water purification and brackish and sea water treatment for drinking purpose. It covers the identification, mapping and evaluation of the on-going research, in order to propose future research and co-operation strategies.

Download or read book Treatability of Perchlorate Containing Water by RO NF and UF Membranes written by Gary Amy and published by IWA Publishing. This book was released on 2004-01-01 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: The California Department of Health Services has established a provisional action level of 4 ug/L for perchlorate in drinking water due to its toxicity. There are 14 states in the United States that have thus far confirmed perchlorate in ground or surface waters. Ongoing research is investigating other treatment technologies for perchlorate rejection, including biological degradation, ion exchange, and activated carbon. The major objectives of this project were to: determine the removal/rejection of perchlorate (ClO4-) ion by high pressure membranes, including reverse osmosis (RO), nanofiltration (NF), and tight ultrafiltration (UF); evaluate the effects of water quality parameters, pH, ionic strength (conductivity), and co-ions and counter-ions, on process performance; and study membrane operating conditions (e.g., recovery) on perchlorate rejection and potential scaling. Water quality is a determining factor in applying high pressure membranes to perchlorate rejection. Effective rejection of perchlorate by RO, NF, and tight UF has been demonstrated according to two rejection mechanisms: steric (size) versus electrostatic (charge) exclusion. Based on its size (hydrodynamic radius), perchlorate is selectively rejected over chloride through size exclusion; however, based on charge exclusion, sulfate is selectively rejected over perchlorate.

Download or read book Natural Organic Matter in Water written by Mika Silanpää and published by Butterworth-Heinemann. This book was released on 2014-10-07 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: Approximately 77 percent of the freshwater used in the United States comes from surface-water sources and is subject to natural organic matter contamination according to the United States Geological Survey. This presents a distinct challenge to water treatment engineers. An essential resource to the latest breakthroughs in the characterization, treatment and removal of natural organic matter (NOM) from drinking water, Natural Organic Matter in Waters: Characterization and Treatment Methods focuses on advance filtration and treatment options, and processes for reducing disinfection byproducts. Based on the author’s years of research and field experience, this book begins with the characterization of NOM including: general parameters, isolation and concentration, fractionation, composition and structural analysis and biological testing. This is followed by removal methods such as inorganic coagulants, polyelectrolytes and composite coagulants. Electrochemical and membranes removal methods such as: electrocoagulation, electrochemical oxidation, microfiltration and ultrafiltration, nanofiltration and membrane fouling. Covers conventional as well as advanced NOM removal methods Includes characterization methods of NOM Explains removal methods such as: removal by coagulation, electrochemical, advanced oxidation, and integrated methods
Download or read book Analysis Removal Effects and Risk of Pharmaceuticals in the Water Cycle written by and published by Newnes. This book was released on 2013-11-26 with total page 759 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analysis, Removal, Effects and Risk of Pharmaceuticals in the Water Cycle provides an overview of the current analytical methods for trace determination of pharmaceuticals in environmental samples. The book also reviews the fate and occurrence of pharmaceuticals in the water cycle for their elimination in wastewater and drinking water treatment, focusing on the newest developments in treatment technologies, such as membrane bioreactors and advanced oxidation processes. Pharmaceutically active substances are a class of new, so-called emerging contaminants that have raised great concern in recent years. Human and veterinary drugs are continuously being released into the environment mainly as a result of the manufacturing processes, the disposal of unused or expired products, and via excreta. The analytical methodology for the determination of trace pharmaceuticals in complex environmental matrices is still evolving, and the number of methods described in the literature has grown considerably. This volume leads the way, keeping chemistry students, toxicologists, engineers, wastewater managers and related professionals current with developments in this quickly evolving area. Covers the latest developments in trace determinations Concise and critical compilation of the recent literature Focuses on new treatment technologies

This book was released on 2005-04-30 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wastewater and drinking water treatment are essential elements of urban infrastructure. In the course of the last century there has been enormous technical development, so successful that for the general public in industrialized countries this infrastructure is hardly noticed. Nevertheless there is ongoing activity to further improve the existing processes. The IWA Leading Edge Technology conference held in Prague helped to stimulate this development and this book helps disseminate the results. A selection of presentations from the conference are included in this volume. Wastewater and drinking-water treatment are normally considered as two separate fields due to the very different boundary conditions that apply. Nevertheless several issues such as membrane processes, removal of micropollutants and water reuse are of crucial importance to both. This potential for cross-fertilization further enhances the value of this collection of high-quality articles that delineate the leading edge of research and development in water and wastewater treatment.
