This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The respiration rate has generated much interest as a means of monitoring and controlling the activated sludge process because it is directly associated with both biomass growth and substrate removal. Respirometry has long been recognized as a valuable tool for controlling the activated sludge process, and as a result, many respirometry-based control strategies have been proposed in the literature. This study has developed a benchmark and methodology for conducting simulation studies to test the proposed control strategies within a complete and consistent set of process conditions. The benchmark consists of a complete set of influent conditions, a standard activated sludge plant configuration, models for the activated sludge process and the secondary clarification process, as well as values for the model parameters and initial values for the state variables. The benchmark provided the framework for the development of the simulation-based methodology. The methodology uses the benchmark, and includes a set of guidelines for implementing a control strategy in the benchmark plant and a set of tests for evaluating the performance and benefits of a proposed control system. The benchmark and methodology were then applied to test selected control strategies from the literature. (Abstract shortened by UMI.).

This book was released on 1992-02-03 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a thorough overview of respirometry and its scientific and engineering basis. The book describes the fundamentals of biological waste treatment, development of predictive models for system design and operation, and how respirometry fits in with these operations. It also presents case studies, which give you concrete examples of the application of respirometry. This book will help activated sludge process control designers, operators, and managers of biological wastewater treatment facilitieslearn how to improve methods for the analysis of biological wastewater systems, enhance design and treatability projects, optimize and troubleshoot plant operations, and accurately predict the impact of new loads or streams on biological wastewater facilities.

This book was released on 2012-04 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary purpose of this study is the investigation of a wastewater treatment plant in terms of nitrogen removal potential and possible operational problems that may be generated by possible inhibitors. To this end, the characterization of wastewater, biological treatability tests, the investigation of chemicals that can act as inhibitors in the activated sludge systems were examined. Possible inhibitory effects of aromatic hydrocarbons on the biodegradation of domestic wastewater were investigated by respirometric analysis. Naphthalene, n-butyl acetate, and xylene were used as the model PAH compounds.

Download or read book Industrial Wastewater Treatment by Activated Sludge written by Derin Orhon and published by IWA Publishing. This book was released on 2009-02-02 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Industrial pollution is still a major concern and despite its significance, sound and systematic pollution control efforts are very poorly documented. The character and treatability of industrial wastewaters is highly variable and specific for each industrial activity. Biological treatment with activated sludge is the appropriate technology for industrial wastewaters from several major industrial sectors. Industrial Wastewater Treatment by Activated Sludge deals with the activated sludge treatment of industrial wastewaters by considering conceptual frameworks, methodologies and case studies, in a stepwise manner. The issues related to activated sludge treatment, such as biodegradability based characterization, modeling, assessment of stoichiometric and kinetic parameters and design, as well as the issues of industrial pollution control, e.g. in-plant control, effect of pretreatment, etc. are combined in a way to provide a comprehensive and information-rich view to the reader. By doing so, the book supplies an up-to-date reference for industrial wastewater experts and both graduate and undergraduate students. Industrial Wastewater Treatment by Activated Sludge provides a roadmap, describing the methodologies for the treatment of industrial wastewaters from several major sectors, based on a solid theoretical background. Up to now although valuable separate efforts both on activated sludge and industrial wastewater treatment have been presented, an integrated approach that is crucial to practice has not been available. This gap is filled by this book.

This book was released on 2004-11-01 with total page 600 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mathematical modeling is a useful tool for the design, analysis and control of wastewater treatment systems. The activated sludge process is one of the most common processes used in wastewater treatment, and therefore is a particularly important candidate for the application of mathematical models. In the 1980s, a task group organized by the International Association on Water Quality (IAWQ) developed a conceptual model of the activated sludge process, which has become an industry-wide standard for the development of computer-based activated sludge models. A recent version of the IAWQ model incorporates 19 components, 17 processes, and numerous rate and stoichiometric coefficients. It is difficult and costly to quantify all of the necessary coefficients for any given application of the model; consequently, it is important to identify the most critical wastewater and biomass components and the relevant coefficients to be quantified for the most common uses of the model. It is also important to provide guidance to potential model users on the use of default and/or estimated values for the remaining parameters.
