Book REMOVAL OF EMERGING CONTAMINANTS FROM AQUEOUS SOLUTION BY OZONE BASED PROCESSES

Download or read book REMOVAL OF EMERGING CONTAMINANTS FROM AQUEOUS SOLUTION BY OZONE BASED PROCESSES written by Rupam Rani and published by . This book was released on 2013 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: The presence of emerging contaminants (ECs) in water and wastewater systems has become a subject of significant concern worldwide. These emerging contaminants are complex organic molecules which potentially affect human health and environment. Conventional wastewater treatment plants are unable to completely remove these contaminants from water and therefore can discharge them into environment. The need to develop effective methods for ECs removal is essential. This study assess the potential of ozone based advanced oxidation processes (AOP) to oxidize number of emerging contaminants. Different combinations of ozone with hydrogen peroxide and sodium persulfate were tested. For this study 1-4, dioxane, perfluorinated compounds (PFCs), N,N-Diethyl-metatoluamide, and three pharmaceuticals sulfamethoxazole, trimethoprim and carbamazepine have been selected. The effect of different process parameters such as chemical dosages, ozone weight percent, ozone flow rates, etc. on destruction of ECs were examined. It was observed that 1, 4-dioxane were persistent to direct ozone reaction, however were easily oxidized by hydroxyl radical. However, ozonation was solely very effective (> 99 %) in removing pharmaceuticals such as sulfamethoxaole, trimethoprim and carbamazepine. It was not very efficient for the removal of perfluorinated compound and N,N-Diethylmeta-toluamide. The operational conditions were optimized for maximum removal of every compound and their influence on the degradation process is discussed.

Book Chemistry of Ozone in Water and Wastewater Treatment

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.

Book Catalyzed Degradation of Hydrogen Peroxide

Download or read book Catalyzed Degradation of Hydrogen Peroxide written by Christopher Sommer and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Efficient water treatment, a process that has been revolutionized in recent decades, is in high demand as population growth and climate change create worsening global water scarcity. As a result, developments in nanofiltration and reverse osmosis filtration membranes have allowed for water treatment capabilities for challenging streams with high salinities and dissolved contaminants. However, persistent and ubiquitous issues of fouling and concentration polarization (CP) reduce efficiency and increase operational costs within treatment facilities. Thus, an entire field of research has been developed in order to determine long-term, holistic solutions to these issues to be implemented in future water treatment systems. This thesis discusses the current and predicted future state of global water scarcity and the current capabilities, applications, and limitations of membrane water treatment systems as well as some common implementations and practices used to mitigate the persistent issues of fouling and concentration polarization. This thesis also discusses in detail a study conducted by several researchers in the Penn State University Department of Chemical Engineering, which finds definitive conclusion for in-situ metallic salt nanoparticle catalytic coatings as a solution to energy losses due to fouling and CP. Finally, the catalase enzyme will be discussed as a possible catalytic coating in future reactive micromixing experiments.
