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 2010 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical disinfection has been for the last 100 years, an integral part of municipal drinking water treatment, in order to achieve the protection of public health. Some time ago, the addition of disinfectant was just as much as required to remove all the microorganisms. Further experience has shown that it is not that simple, due to the disinfection byproducts (DBPs) that appear during this process, which can significantly affect the consumer health. In order to deal with the DBPs, the main health organizations and governments have introduced pretty restrictive limits that must be achieved in order to guarantee the supply of safe drinking water. There are several ways to achieve the required thresholds, because of the chemistry of formation of the byproducts. Taking a look in the next expression, the different ways of reducing them can be easily seen: Natural Organic Matter + disinfectant -- disinfection byproducts In order to reduce the disinfection byproducts, while keeping a good water quality, the removal of natural organic matter (NOM) is the key factor. NOM is present in almost all sources of water all around the world, and is a mixture of several organic compounds. It is considered harmless, but due to its reaction with the disinfectant its removal has been deeply studied. When the NOM is removed, a removal of the colour, ultraviolet absorbance at 254 nm (UV-254) and some other are also expected. This means that the reduction of the NOM will be achieved with the same methods that traditionally have been used to remove these parameters. In this study, the methods that have been analyzed are: 1) chemical coagulation and precipitation; 2) adsorption on activated carbon and 3) magnetic ion exchange. The first one, has been deeply studied for many years, and is a well known and popular method. The next two, because of having appeared more recently, still need to be studied. The aim of this project is to investigate these treatment options for water containing elevated levels of NOM, and then enhance its removal by optimizing the proposed processes as a single unit, to obtain the proper operation conditions, as well as assessing the combination of the proposed optimized processes, with the monitoring of the bulk parameters and the molecular weight range removal.

Available in PDF, EPUB and Kindle. Book excerpt: As part of the effort to balance water treatment processes between allowing pathogenic infection by doing too little, and raising the risk of cancer with by-products of the treatment, 20 papers from a symposium in Chicago, August 1995, present information on the chemical identity of natural organic matter and its interactions with the inorganic precursor bromide ion. They review the history of natural organic matter in water treatment and the impact of regulations, then plunge into reports on an economical experimental approach to developing predictive models for by-products of disinfection, a comparison of analytical techniques for determining cyanogen chloride in chloraminated drinking water, the effect of ozonation and biotreatment on molecular size and hydrophilic fractions of natural organic matter, removing bromate ion by electric-arc discharge and high-energy electron beam processes, and other topics.

Download or read book Evaluation of Anion Exchange and Adsorption for Natural Organic Matter Nom Pretreatment from Two Surface Waters Using a Two Stage Countercurrent Reactor written by Katherine Graf and published by . This book was released on 2013 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Isotherms and modeling were done to determine the doses necessary for 99% removal of the adsorbable fraction of DOC. The average 2nd stage percent removal of adsorbable DOC removal with SJR water and VA water for F400, PFA444, and MIEX were 109% and 84%, 90% and 88%, and 85% and 94%, respectively. These results show that the modeling was relatively effective in predicting the doses and that the two-stage countercurrent process was able to remove more DOC than the single-stage process.

This book was released on 2000 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research reported on here sought to characterize natural organic matter (NOM) in dilute solutions and to isolate it without altering its properties, so that the effect of NOM in drinking water may be considered. Several NOM isolation methods were evaluated, including evaporation, reverse osmosis, nanofiltration, and adsorption. The effects of such isolation procedures on NOM's chemical composition and reactivity were considered. Based on these studies, the report presents conclusions regarding the feasibility and adequacy of in situ and ex situ techniques.

This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Dissolved organic matter (DOM) and hardness cations are two common constituents of natural waters that substantially impact water treatment processes. Anion exchange treatment, and in particular magnetic ion exchange (MIEX), has been shown to effectively remove DOM from natural waters. An important advantage of the MIEX process is that it is used as a slurry in a completely mixed flow reactor at the beginning of the treatment train. Hardness ions can be removed with cation exchange resins, although typically using a fixed bed reactor at the end of a treatment train. In this research, the feasibility of combining anion and cation exchange treatment in a single completely mixed reactor for treatment of raw water was investigated. The sequence of anion and cation exchange treatment, the number of regeneration cycles, and the chemistry of the regeneration solution were systematically explored. Simultaneous removal of DOM ([greater than] 70% dissolved organic carbon) and hardness ([greater than] 50% total hardness) was achieved by combined ion exchange treatment. This treatment would prove useful for raw waters that are a mixture of groundwater and surface water and as a pre-treatment for membrane systems as both DOM and calcium are major foulants.
