Ozonation and Biodegradation in Environmental Engineering: Dynamic Neural Network Approach gives a unified point-of-view on the application of DNN to estimate and control the application of ozonation and biodegradation in chemical and environmental engineering. This book deals with modelling and control design of chemical processes oriented to environmental and chemical engineering problems. Elimination in liquid, solid and gaseous phases are all covered, along with processes of laboratory scale that are evaluated with software sensors and controllers based on DNN technique, including the removal of contaminants in residual water, remediation of contaminated soil, purification of contaminated air, and more. The book also explores combined treatments using both ozonation and biodegradation to test the sensor and controller. Defines a novel researching trend in environmental engineering processes that deals with incomplete mathematical model description and other non-measurable parameters and variables Offers both significant new theoretical challenges and an examination of real-world problem-solving Helps students and practitioners learn and inexpensively implement DNN using commercially available, PC-based software tools
The leading resource on ozone technology, this book contains everything from chemical basics to technical and economic concerns. The text has been updated to include the latest developments in water treatment and industrial processes. Following an introduction, the first part looks at toxicology, reaction mechanisms and full-scale applications, while Part B covers experimental design, equipment and analytical methods, mass transfer, reaction kinetics and the application of ozone in combined processes.
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.
Advanced Ozonation Processes for Water and Wastewater Treatment introduces the state-of-the-art catalysts used in catalytic ozonation and various combined processes with ozone.
This book contains a collection of different research activities where several technologies have been applied to the optimization of biodegradation processes. The book has three main sections: A) Hydrocarbons biodegradation, B) Biodegradation and anaerobic digestion, and C) Biodegradation and sustainability.
Ozonation, peroxone, and ozone/PS are selected as treatment methods; and p-cresol is used as model pollutant in this study. All experiments were conducted in semi-batch mode using laboratory-scale ozonation reactor. The scope of research includes parameters study such as O3 gas flow rate, oxidants dosage, pH, and operating temperature. The performance of methods studied was evaluated in terms of p-cresol reduction, COD reduction, and changes of pH and ORP in reaction medium. Whereas, the degradation intermediate products of p-cresol were identified through UV-Vis and IR absorption spectra, total ion chromatograph (TIC), and mass spectra. The research scope in accordance with respective research objective can be well-represented by experimental matrix (Appendix B) and was briefly described as below. This study focuses on the performance of ozonation, peroxone, and ozone/PS in degrading persistent organic pollutant by using p-cresol as model pollutant. The performance of ozonation and combination of ozonation with H2O2 or persulfate was evaluated and compared with respect to increasing initial p-cresol concentrations as well as pH conditions of reaction medium. The processes parameters in ozonation, peroxone, and ozone/PS including O3 gas flow rate, oxidants dosage, pH as well as operating temperature were optimised in order to enhance the processes performance. Response surface methodology Box-Behnken design (BBD) was also employed to investigate the effect of interaction between parameters. Other than that, the kinetic model of p-cresol degradation was developed; subsequently establish its relationship with processes parameters. The intermediate products in p-cresol degradation were identified through UV-Vis spectrometry, FTIR spectrometry, and GCMS. Accordingly, the degradation pathways of p-cresol were proposed by taking into account of oxidation mechanisms of oxidants involved in the processes.
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.
