This book was released on 2006 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: UV/H2O2 advanced oxidation of drinking water for taste and odour control was performed using natural waters to optimize treatment conditions and monitor effects on chlorine decay, chloramine decay, and disinfection by-product (DBP) formation. The optimal dose of H2O2 for the removal of two taste and odour compounds in a raw water sample was 6-10 mg/L. From bench-scale tests, both UV alone (2000 mJ/cm2) and UV/H2O2 resulted in lower levels of chlorine and chloramine residuals when compared to controls. The application of UV/H 2O2 to natural water samples resulted in variable (water-specific) effects on DBPs, with considerable differences between concentrations in controls and in samples exposed to UV/H2O2. Results from this research highlight the importance of performing site-specific evaluations when establishing the feasibility of using UV/H2O 2 for taste and odour control, since it may have a significant impact on secondary disinfectant stability and DBP formation in the distribution system in some waters.

Download or read book Ozone Peroxide Advanced Oxidation in Combination with Biofiltration for Taste and Odour Control and Organics Removal written by Divyam Beniwal and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2009 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cornwall Water Purification Plant collaborated with the University of Toronto to monitor UV-H2O2 treatment performance. This study includes a review of engineering and operational aspects of UV-H 2O2 implementation. A number of operational challenges were experienced with retrofitting UV-H2O2 into the existing treatment plant, and an overview of the challenges and solutions faced at Cornwall is given. The project also includes a thorough water quality analysis. Taste and odour (T&O) events have been monitored for three years and the efficiency of UV-H2O2 on T&O removal is reported. Furthermore, little is known about any potential side effects of the treatment on downstream processes, especially secondary disinfection. The impact of UV-H2O2 on natural organic matter alterations, chlorine stability and disinfection by-product formation is reported using results from full-scale water quality monitoring campaigns at Cornwall, combined with laboratory experiments.

Download or read book Chemical Water and Wastewater Treatment IX written by Hermann H. Hahn and published by IWA Publishing. This book was released on 2007-05-16 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: The question of whether or not we will reach the ambitious goal of the Millennium Declaration still dominates the discussions of water supply and sanitation experts on all levels, governmental, institutional, technological and operational. Our contribution, the Proceedings of the 12th Gothenburg Symposium, the symposium for the sharing of scientific and practical experience in integrated water resources management, is mainly a technological one. This book, as has its predecessors in the series, provides information and technical solutions to accomplish this mammoth task. It is the outcome of collective experience and know-how exchanged between experts in the field of water technology from all over the world, from the Americas, from Central and Southern Africa, from Europe and from different parts of Asia. However, we must realise that very often it is not the technological development that determines progress but rather the legal, financial and organisational framework. And so this book and this symposium differs from its predecessors in that, for the first time, the focus is also on these non-technical aspects that may or may not set the stage for our technological solutions. The Chemical Water and Wastewater Treatment Series provides authoritative coverage of the key current developments in the chemical treatment of water and wastewater, in theory or practice, and related problems such as sludge production, as well as properties, and the reuse of chemicals and chemically-treated waters and sludges. Chemical Water and Wastewater Treatmentis a valuable resource for managers, scientists, plant operators and others interested in chemical water and wastewater treatment technology.
Download or read book Chemistry of Ozone in Water and Wastewater Treatment written by Clemens von Sonntag and published by IWA Publishing. This book was released on 2012-08-31 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Computational Fluid Dynamics in Drinking Water Treatment written by Bas Wols and published by IWA Publishing. This book was released on 2011-10-20 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Special Offer: KWR Drinking Water Treatment Set - Buy all five books together and save £119! Computational Fluid Dynamics (CFD) uses advanced numerical models to predict flow, mixing and (bio)-chemical reactions. In drinking water engineering, CFD is increasingly applied to predict the performance of treatment installations and to optimise these installations. A lack of understanding of the hydraulics in drinking water treatment systems has resulted in suboptimal design of installations. The formation of unwanted disinfection-by-products and the energy consumption or use of chemicals is therefore higher than necessary. The aim of this work is to better understand the hydraulic and (bio)-chemical processes in drinking water treatment installations using experimental and numerical techniques. By combining these techniques, CFD modelling is further developed as a tool to evaluate the performance of these installations. This leads to new insights in the applicability of models in ozone and UV systems, and new insights in design concepts of these systems. CFD modelling proves to be a powerful tool to understand the hydrodynamic and (bio)-chemical processes in drinking water systems. If applied properly, accounting for the complex turbulent motions and validated by experiments, this tool leads to a better design of UV reactors, ozone systems and other systems dictated by hydraulics.

This book was released on 2018-07-03 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume reviews the drinking water treatments in which AOPs display a high application potential. Firstly it reveals the typical supply sources and limitations of conventional technologies and critically reviews natural organic matter characterization and removal techniques, focusing mainly on AOP treatments. It then explores using AOPs for simultaneous inactivation/disinfection of several types of microorganisms, including highly resistant Cryptosporidium protozoa. Lastly, it discusses relevant miscellaneous topics, like the most promising AOP solid catalysts, the regime change of Fenton-like processes toward continuous reactors, the application of chemometrics for process optimization, the impact on disinfection byproducts and the tracing of toxicity during AOP treatments. This work is a useful reference for researchers and students involved in water technologies, including analytical and environmental chemistry, chemical and environmental engineering, toxicology, biotechnology, and related fields. It is intended to encourage industrial and public-health scientists and decision-makers to accelerate the application of AOPs as technological alternatives for the improvement of drinking water treatment plants.
