Book excerpt: Methyl tert-butyl ether (MTBE) is currently the leading contaminant of groundwater in the United States. The widespread presence of MTBE along with its degradation by-product, tert-butyl alcohol (TBA), in groundwater has created great concern in the scientific community because MTBE and TBA are suspected as possible human carcinogens. In this research, the degradation of MTBE and TBA in aqueous solution by O33/UV process has been investigated. Laboratory studies were conducted using a semi-batch reactor under various experimental conditions, i.e., incident UV light intensity, influent ozone gas concentration, and water quality in terms of varying bicarbonate concentration. Furthermore, the O33/UV process was modeled by using oxalic acid as a probe chemical. Oxalic acid was oxidized by O33/UV process under various experimental conditions; and the model successfully predicted the residual concentration of oxalic acid. In order to understand the degradation mechanisms of MTBE and TBA, a comprehensive kinetic model that describes the degradations of MTBE, TBA and their intermediates by O33/UV process was proposed. The model was calibrated using experimental data on MTBE and TBA spiked in synthetic solution. An attempt was made to verify the kinetic model using different sets of experimental data. The model predicted well the removal of MTBE and TBA; however, the accumulation and decay of some primarily intermediates were predicted with slight variations. Finally, real groundwater samples contaminated with MTBE and TBA were oxidized by O33/UV process under various experimental conditions. It was observed that the removal rate of MTBE and TBA was reduced by the presence of other gasoline components, such as BTEX. Furthermore, for groundwater sample without iron the kinetic model predicted the degradation of MTBE as well as accumulation and decay of reaction intermediates with slight variations. In conclusion, this research provides valuable information on the degradation mechanisms of MTBE, TBA, and their intermediates. The O33/UV process was very successful in degrading MTBE and TBA in aqueous solution. Moreover, it was observed that the reaction intermediates react well in the O33/UV process, and complete mineralization could be achieved, if desired.

Available in PDF, EPUB and Kindle. Book excerpt: 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

This book was released on 2013-02-27 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: Across the United States, thousands of hazardous waste sites are contaminated with chemicals that prevent the underlying groundwater from meeting drinking water standards. These include Superfund sites and other facilities that handle and dispose of hazardous waste, active and inactive dry cleaners, and leaking underground storage tanks; many are at federal facilities such as military installations. While many sites have been closed over the past 30 years through cleanup programs run by the U.S. Department of Defense, the U.S. EPA, and other state and federal agencies, the remaining caseload is much more difficult to address because the nature of the contamination and subsurface conditions make it difficult to achieve drinking water standards in the affected groundwater. Alternatives for Managing the Nation's Complex Contaminated Groundwater Sites estimates that at least 126,000 sites across the U.S. still have contaminated groundwater, and their closure is expected to cost at least $110 billion to $127 billion. About 10 percent of these sites are considered "complex," meaning restoration is unlikely to be achieved in the next 50 to 100 years due to technological limitations. At sites where contaminant concentrations have plateaued at levels above cleanup goals despite active efforts, the report recommends evaluating whether the sites should transition to long-term management, where risks would be monitored and harmful exposures prevented, but at reduced costs.

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.
