Chemistry of Ozone in Water and Wastewater Treatment

Chemistry of Ozone in Water and Wastewater Treatment PDF Author: Clemens von Sonntag
Publisher: IWA Publishing
ISBN: 1843393131
Category : Science
Languages : en
Pages : 306

Book Description
Even though ozone has been applied for a long time for disinfection and oxidation in water treatment, there is lack of critical information related to transformation of organic compounds. This has become more important in recent years, because there is considerable concern about the formation of potentially harmful degradation products as well as oxidation products from the reaction with the matrix components. In recent years, a wealth of information on the products that are formed has accumulated, and substantial progress in understanding mechanistic details of ozone reactions in aqueous solution has been made. Based on the latter, this may allow us to predict the products of as yet not studied systems and assist in evaluating toxic potentials in case certain classes are known to show such effects. Keeping this in mind, Chemistry of Ozone in Water and Wastewater Treatment: From Basic Principles to Applications discusses mechanistic details of ozone reactions as much as they are known to date and applies them to the large body of studies on micropollutant degradation (such as pharmaceuticals and endocrine disruptors) that is already available. Extensively quoting the literature and updating the available compilation of ozone rate constants gives the reader a text at hand on which his research can be based. Moreover, those that are responsible for planning or operation of ozonation steps in drinking water and wastewater treatment plants will find salient information in a compact form that otherwise is quite disperse. A critical compilation of rate constants for the various classes of compounds is given in each chapter, including all the recent publications. This is a very useful source of information for researchers and practitioners who need kinetic information on emerging contaminants. Furthermore, each chapter contains a large selection of examples of reaction mechanisms for the transformation of micropollutants such as pharmaceuticals, pesticides, fuel additives, solvents, taste and odor compounds, cyanotoxins.

Ozonation of Water and Waste Water PDF Author: Christiane Gottschalk

ISBN: 3527613358
Category : Science
Languages : en
Pages : 199

Book Description
The ozonation of compounds in water is a complex process. The mechanisms are very complicated, the parameters are many, but the possibilities of developing cost-effective treatment schemes for drinking water and waste water are large. Most books available today concentrate on either drinking water or waste water treatment, seldom dealing with both or explaining the essential differences. And only rare exceptions deal with the how-to of ozone experiments. This practical guide fills the gap. It contains the cumulative knowledge on experimental design, execution, interpretation and application. Drawing on experience gained from hours spent on laboratory research with drinking and waste waters, literature study, intensive discussion with leading experts, perplexed reflection and deep thought, the book offers practical help to avoid common pitfalls and unnecessary work. This book is aimed at professionals in industry and research currently using ozonation who want to optimize their system, as well as students beginning work with ozonation. It contains just enough information for beginners to start with, but goes rapidly to the detailed information that advanced readers need.

ISBN: 9780873714747
Category : Technology & Engineering
Languages : en
Pages : 602

Book Description
With the advent of the Safe Drinking Water Act Amendments of 1986, many water utilities are reexamining their water treatment practices. Upcoming new regulations on disinfection and on disinfection by-products, in particular, are the primary driving forces for the big interest in ozone. It appears that ozone, with its strong disinfection capabilities, and apparently lower levels of disinfection by-products (compared to other disinfectants), may be the oxidant/disinfectant of choice. Many utilities currently using chlorine for oxidation may need to switch due to chlorine by-product concerns. Utilities using chloramines may need to use ozone to meet CT requirements. This book, prepared by 35 international experts, includes current technology on the design, operation, and control of the ozone process within a drinking water plant. It combines almost 100 years of European ozone design and operating experience with North American design/operations experience and the North American regulatory and utility operational environment. Topics covered include ozone chemistry, toxicology, design consideration, engineering aspects, design of retrofit systems, and the operation and economics of ozone technology. The book contains a "how to" section on ozone treatability studies, which explains what information can be learned using treatability studies, at what scale (bench, pilot, or demonstration plant), and how this information can be used to design full-scale systems. It also includes valuable tips regarding important operating practices, as well as guidance on retrofits and the unique issues involved with retrofitting the ozone process. With ozone being one of the hottest areas of interest in drinking water, this book will prove essential to all water utilities, design engineers, regulators, and plant managers and supervisors.

Ozone/Peroxide Advanced Oxidation in Combination with Biofiltration for Taste and Odour Control and Organics Removal

Book Description
Ozone (O3) prior to biofiltration can be an effective treatment strategy to achieve multiple drinking water quality goals. These goals include primary disinfection, improved removal of biodegradable organic carbon (generated as a result of ozonation), and oxidation of geosmin and MIB. However, O3 efficiency is dependent on source water characteristics, which impacts performance. This pilot study investigated the effectiveness of advanced oxidation incorporating O3 and hydrogen peroxide/ozone (H2O2/O3) with biofiltration (containing biologically active carbon (BAC) and anthracite) for geosmin and MIB control and disinfection by-product (DBP) precursor reduction. Application of 0.2 H2O2/O3 (mg/mg) prior to BAC resulted in optimal MIB and geosmin removal, especially in cold-water conditions (T = 10°C). In warmer temperatures (22°C), BAC alone was a suitable treatment technology for both geosmin and MIB. In terms of DBP precursor reduction, 0.1 H2O2/O3 (mg/mg) in combination with BAC was found to be the most effective treatment strategy with 37% THM and 10% HAA precursor reductions.

Removal of MTBE with Advanced Oxidation Processes

Removal of MTBE with Advanced Oxidation Processes PDF Author: Michael Kavanaugh
Publisher: IWA Publishing
ISBN: 1843398613
Category : Science
Languages : en
Pages : 270

Book Description
The purpose of this project was to perform a careful evaluation of the technical and economic feasibility of advanced oxidation processes (AOPs) for methyl tertiary butyl ether (MTBE) removal. Specifically, the first objective of this project was to identify and fill data gaps related to the implementation and operation of AOPs with respect to MTBE removal. The second objective was to select and optimize the design of the most promising AOP(s) as a function of water quality parameters. The third objective was to determine conceptual-level engineering costs for these selected AOPs. The AOP technologies that were evaluated as part of this study included ozone/peroxide, continuous wave UV/peroxide, pulsed UV/peroxide, and E beam. The AOP technologies were compared with treatment costs, qualitative factors (e.g., technology reliability, flexibility), and influent and treated water quality considerations. Based on the comparative analysis, it was concluded that all the AOP technologies that were evaluated in this study are capable of removing MTBE at 95% or higher efficiencies. Ozone/peroxide and continuous UV/peroxide appear to be the most feasible technologies for AOP treatment of MTBE in drinking water sources. Originally published by AwwaRF for its subscribers in 2003
