Available in PDF, EPUB and Kindle. Book excerpt: Wastewater containing acetic acid has long been produced by the chemical industry. Improper disposal of the wastewater has become a major problem as it pollutes the environment and destroys aquatic ecosystem. The wastewater has to be treated before it can be released into the environment. Some of the treatment methods include membrane processes and wet air oxidation (WAO). These treatment methods have a few limitations. Membrane processes are limited by their solvent and thermal stability and WAO is only effective at severe operating conditions. In this research, catalytic wet air oxidation (CWAO) is the proposed method for treatment. The catalyst was synthesized according to the wetness method. The experiment was conducted by oxidizing simulated wastewater containing acetic acid in a batch reactor. The reaction study was repeated with the manipulation of two different operating parameters. The sample was analysed using Total Organic Content (TOC) analysis and Gas Chromatography (GC). The catalyst was characterized by X-ray diffraction (XRD) and Physisorption analysis (BET Method). CWAO yielded the highest conversion at the temperature of 80°C. The catalyst with high surface area was confirmed by XRD and BET. The conversion using CWAO was higher than other processes as predicted. The presence of the catalyst reduced the severity of the operating conditions and also increased the conversion rate.

Available in PDF, EPUB and Kindle. Book excerpt: Acrylic acid (AA) is one of the hazardous organic compounds that can be found in industrial wastewater which can cause serious damage to the environment and health. From this research, catalytic wet air oxidation (CWO) process has been used with the presence of Manganese-Cerium Oxide catalyst in order to oxidise acrylic acid in the less severe operating condition. In the present research, the Manganese-Cerium Oxide catalyst (Ce-Mn-1) was prepared by co-precipitation and characterized by using X- ray diffraction (XRD), X-ray flusoncen (XRF), Brunauer, Emmett, and Teller theory (BET) and Barrett, Joyner, and Halenda (BJH) analysis. In addition, performance of the catalyst in CWO of wastewater containing Acrylic Acid was obtained by manipulating different operating parameters, which are temperature, and the concentration of Acrylic Acid. The catalytic activity was analyzed by Chemical Oxygen Demand (COD) analysis method. The catalyst with manganese/cerium ratio 67/33 was successful synthesized with specific surface area, 83.1155 m2g-1 and pore volume 0.3031cm3g-1. Although the synthesized catalyst showed good physical characteristic but the literature COD reduction data obtained is fluctuating due to the side reaction polymerization and formation of carbonic acid during the experiments. As the conclusion the characteristics of catalyst shown a good result but due to the side reaction occur during the experiments, the catalytic activity can't be determined.

Download or read book Advanced Oxidation Processes for Water and Wastewater Treatment written by Simon Parsons and published by IWA Publishing. This book was released on 2004-03-01 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: The suitability of Advanced Oxidation Processes (AOPs) for pollutant degradation was recognised in the early 1970s and much research and development work has been undertaken to commercialise some of these processes. AOPs have shown great potential in treating pollutants at both low and high concentrations and have found applications as diverse as ground water treatment, municipal wastewater sludge destruction and VOCs control. Advanced Oxidation Processes for Water and Wastewater Treatment is an overview of the advanced oxidation processes currently used or proposed for the remediation of water, wastewater, odours and sludge. The book contains two opening chapters which present introductions to advanced oxidation processes and a background to UV photolysis, seven chapters focusing on individual advanced oxidation processes and, finally, three chapters concentrating on selected applications of advanced oxidation processes. Advanced Oxidation Processes for Water and Wastewater Treatment will be invaluable to readers interested in water and wastewater treatment processes, including professionals and suppliers, as well as students and academics studying in this area.

This book was released on 2007-11-10 with total page 697 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past thirty years have witnessed a growing worldwide desire that po- tive actions be taken to restore and protect the environment from the degr- ing effects of all forms of pollution—air, water, soil, and noise. Because pollution is a direct or indirect consequence of waste, the seemingly idealistic demand for “zero discharge” can be construed as an unrealistic demand for zero waste. However, as long as waste continues to exist, we can only attempt to abate the subsequent pollution by converting it to a less noxious form. Three major questions usually arise when a particular type of pollution has been id- tified: (1) How serious is the pollution? (2) Is the technology to abate it ava- able? and (3) Do the costs of abatement justify the degree of abatement achieved? This book is one of the volumes of the Handbook of Environmental Engineering series. The principal intention of this series is to help readers f- mulate answers to the last two questions above. The traditional approach of applying tried-and-true solutions to specific pollution problems has been a major contributing factor to the success of en- ronmental engineering, and has accounted in large measure for the establi- ment of a “methodology of pollution control. ” However, the realization of the ever-increasing complexity and interrelated nature of current environmental problems renders it imperative that intelligent planning of pollution abatement systems be undertaken.

This book was released on 2022-05-11 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among various industries releasing wastewater into the environment, printing, dyeing and textile industries are of great importance as they frequently contain high amounts of colorful compounds having high chemical and biological oxygen demands. Health related effects of colorants are extensively reported; which necessitates the seriousness of dye removal from water and wastewater. The utilization of advanced oxidation processes (AOPs) in dye degradation has gained considerable attention recently due to the release of high energetic radicals as oxidants that are capable of removing dye compounds. This Volume 1 presents versatile applications of AOPs in dye removal. Accordingly, processes such as Ozone-based AOPs, UV irradiation, catalytic AOPs, etc are discussed with the aim of dye removal under different operational parameters. The role of different nanoparticles is also investigated. By presenting the fundamentals of AOPs as well as recent advances, this book is useful for environmental engineers and chemists who are concerned with wastewater pollution and treatment.
