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

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.

Available in PDF, EPUB and Kindle. Book excerpt: The biggest impediment for applying membrane processes is fouling from natural organic matter (NOM) and particles. Fouling reduces the flux through membranes, increasing both the capital and operating costs. Softening is traditionally designed to remove hardness ions in hard waters, but it also has the capability to remove particles and organic matter. However, virtually no effort has been directed toward using softening as a pretreatment before membrane processes. This research was designed to fill that gap. The following are highlights from the project: Organic matter, i.e., natural organic matter or a simple organic component used as a NOM surrogate, is the most detrimental foulant on the membrane process. Three softening conditions were defined: standard softening (the smallest lime dose to achieve minimum calcium concentration), enhanced softening (the highest lime dose before massive precipitation of magnesium hydroxide), and magnesium softening (the lime dose that precipitates more than 90% of the magnesium. Magnesium softening was capable of dramatically reducing the fouling by all waters tested, but enhanced softening was almost as good for most waters and would generally be sufficient.

Download or read book Natural Organic Matter Fouling of Low-Pressure Membrane Systems written by J. Lozier and published by IWA Publishing. This book was released on 2008-10-14 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low-pressure (LP) membrane use has increased dramatically over the last decade in response to more stringent pathogen-related drinking water regulations, water reclamation and the need for more effective reverse osmosis pretreatment, and from dramatically reduced membrane costs. More cost-effective and reliable operation of LP membrane systems is constrained, however, by fouling, in particular fouling by NOM. NOM fouling is poorly understood because of both the complexity and types of NOM that exists in natural sources and wastewater effluent and NOM-membrane interactions. This report is available as a Pay-Per-View item only. NOM exists in three primary forms (allochthonous, autochthonous, and effluent-derived), with a variety of components having differing fouling tendencies. LP membranes comprise hollow fibers of differing polymeric materials, with a range of properties that likewise influence fouling propensity. Fouling management strategies (backwash, air scrub, chemical cleaning) employed with LP membrane systems differ from supplier to supplier. This, combined with a number of the methods used to reduce NOM levels prior to membrane treatment (e.g., coagulation, clarification), further complicate the understanding of NOM fouling. The overall goal of this project was to investigate the specific contributions of the different types of natural organic matter (NOM) to microfiltration/ultrafiltration (MF/UF) fouling. The intent was to develop a surrogate test or index that could be used to predict NOM fouling at low cost through a combination of source water characterization and rapid bench-scale testing. The research incorporated bench-, pilot- and full-scale investigations. Testing was conducted with four source waters, selected to capture the fouling characteristics of the three primary types of NOM. Bench testing use a stirred, cell apparatus and three flat sheet membrane types, representing commercially dominant MF and UF hollow fiber membranes of the same polymer types. Hollow fiber bench testing used two PVDF and two PES membranes operated in both sequential and alternating filtration/backwash mode. Pilot testing included PVDF MF and UF and PES UF systems operated on three of the four source waters and incorporated a host of fouling management strategies. Full-scale investigations captured operating data from several plants having differing levels and types of NOM.

Available in PDF, EPUB and Kindle. Book excerpt: Pressure Retarded Osmosis: Renewable Energy Generation and Recovery offers the first comprehensive resource on this method of generating renewable energy. Dr. Khaled Touati and the team of editors combine their expertise with contributions from other leaders in the field to create this well-rounded resource, which discusses and analyses this novel method of creating a controllable renewable energy. The promises of the PRO technique are first clearly presented and explained, and the authors then provide a comprehensive analysis of the issues that remain such as Concentration Polarization, Membrane Deformation, and Reverse Salt Diffusion. Possible solutions to these issues which often restrict industrial implementation are then discussed to mitigate these detrimental effects, and there is also an emphasis on the recovery of energy from desalination processes using PRO, which is able to reduce energy consumption and make it more economically and environmentally efficient. Combines research with experience to deliver a complete resource on Pressure Retarded Osmosis Discusses all areas of PRO in detail Offers solutions to problems commonly experienced and summarizes each method with a clear and concise conclusion Includes case studies from the Great Salt Lake (U.S.A) and Dead Sea (Asia), as well as other rivers from America, Europe, and Asia
