Book excerpt: In the past, industrial wastewater treatment primarily focused on the removal of BOD and suspended solids. In recent years, however, the focus has changed to aquatic toxicity, priority pollutants, and volatile organics. This required changes in how we design and operate biological treatment plants. Many existing plants must be retrofitted. New approaches to meet new requirements are discussed in detail. The authors, with a combined experience of sixty years, have presented case studies for a wide variety of industrial wastewaters including pulp and paper, food processing, chemical and pharmaceuticals, and textile wastewaters. Data interpretation and process design are developed through the use of seventeen examples. Procedures for the laboratory and pilot plant generation of process design data are presented. Emphasis is placed on meeting the many new regulations governing industrial wastewater discharges.

This book was released on 2023-02-27 with total page 626 pages. Available in PDF, EPUB and Kindle. Book excerpt: Activated sludge is the most widely used biological wastewater treatment process globally to date, although its high energy demand makes it a major contributor of greenhouse gas emissions. Over recent decades it has been constantly modified and retrofitted to treat ever higher loads or improve effluent standards which have often resulted in even greater carbon emissions. Conventional activated sludge treatment is at a crossroads where new sustainable solutions are required if we are to protect the quality of our rivers and meet net-zero carbon targets.The book details current operation and design with special emphasis on the biological aspects of the process. From the microbial kinetics to the fascinating process of floc formation and development, the book explores the development of our understanding of the process looking at new sustainable designs, including biological nutrient removal and new aeration systems. Sludge separation problems and control options are explained, with a trouble-shooting guide to non-bulking problems. Environmental issues including noise, odor, aerosols, micro-plastics and nanoparticles are all reviewed, as is pathogen removal and the problem of antibiotic resistant genes and bacteria. The development of membrane bioreactors has increased process reliability and effluent quality, while integrated fixed-film activated sludge processes are more efficient and compact. The book concludes by exploring how activated sludge can become more sustainable, for example, by carbon harvesting and byproduct recovery.This interdisciplinary book is essential reading for both engineers and scientists whether training at university or practitioners and consultants in the wastewater industry.Related Link(s)

This book was released on 2013-09-30 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Technical information for using activated sludge to treat effluents from multiple industries Covers virtually all traditional and advanced methods, as well as treatability and process modeling New methods for removing U.S. and European regulated microconstituents, trace organics, active pharmaceutical ingredients and other contaminants Explains advances in water reuse and plant retrofitting Useful for in-house training This comprehensive book presents critical information on the applications of activated sludge for treating industrial wastewaters, as well as other effluents that impact POTWs. The book offers details on how advances in activated sludge can be deployed to meet more stringent discharge limits by explaining many novel variations of activated sludge and offering technical guidance on process modeling and optimization. Special attention is given to emerging contaminants and water reuse strategies. Case studies are drawn from the pharma, food and shale gas industries. Based on short courses taught by the authors, as well as hundreds of hours of in-plant consulting, this book offers the tools to understand and modify the activated sludge process for superior and sustainable wastewater treatment. From the Authors' Preface: "After speaking with practitioners, operators and engineers, the authors felt a new text was needed...to cover the following developments: "the continued evolution of the activated sludge process and its numerous designs, configurations and technology developments; "design of industrial water reuse systems...to achieve industry sustainability goals; "changes...from BOD, TSS and nutrient removal to removal of specific organics, toxicity...microconstituents, and more stringent effluent permit limits; "advances in process modeling tools that can be used in combination with treatability testing tools for plant design, optimization and troubleshooting; "concerns over industrial wastewater discharge impacts to POTWs, such as nitrification inhibition, the impact of frac water...and the fate of microconstituents through POTWs."

This book was released on 2014 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aerobic wastewater treatment is an energy intensive process that requires 1,322 kWh per million gallons of wastewater treated by the activated sludge process. As energy prices continue to climb, there will be increased pressure on industry to reduce energy consumption to mitigate costs. There is currently a growing interest in the application of anaerobic treatment to domestic wastewater as an alternative to the traditional activated sludge process. Challenges encountered with anaerobic treatment of domestic wastewater are longer acclimation times, and reactor instability. This study assessed the possibility of acclimating high-quality seed sludge to treat dilute domestic wastewater at ambient laboratory temperatures (18-24°C). Seed sludge acquired from a brewery wastewater treatment plant was acclimated in an anaerobic sequencing batch reactor (ASBR) within six weeks using two different methods. The acclimated sludge reached COD removals between 60-70% in ASBR mode. The acclimated sludge was then tested for COD reduction in an upflow anaerobic sludge bed (UASB) reactor and compared to a more concentrated unacclimated sludge. Maximum COD removals in the UASB operational phase were 67% for the acclimated sludge and 74% for the unacclimated sludge. The performance of the anaerobic sludge bed reactors (UASB) were modeled indicated good correlation with the Grau second-order model and the modified Stover-Kincannon model. The results of this study indicate the ability to acclimate biomass in both ASBR and UASB reactors to treat low-strength (

Book excerpt: Aerobic Granular Sludge has recently received growing attention by researchers and technology developers, worldwide. Laboratory studies and preliminary field tests led to the conclusion that granular activated sludge can be readily established and profitably used in activated sludge plants, provided 'correct' process conditions are chosen. But what makes process conditions 'correct'? And what makes granules different from activated sludge flocs? Answers to these question are offered in Aerobic Granular Sludge. Major topics covered in this book include: Reasons and mechanism of aerobic granule formation Structure of the microbial population of aerobic granules Role, composition and physical properties of EPS Diffuse limitation and microbial activity within granules Physio-chemical characteristics Operation and application of granule reactors Scale-up aspects of granular sludge reactors, and case studies Aerobic Granular Sludge provides up-to-date information about a rapidly emerging new technology of biological treatment.

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.
