This book was released on 2007-02-01 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Successful operation of the activated sludge process relies heavily on the ability to effectively separate mixed liquor into return activated sludge (RAS) and a high quality final effluent. Solids separation efficiency is dictated in large part by the relative population of floc-forming and filamentous microorganisms present in the activated sludge. During normal operation, mixed liquor will be composed primarily of floc-formers with relatively low levels of filamentous organisms. Some population of filamentous organisms is necessary to promote the formation of larger flocs and prevent development of a "pin-floc" condition, which often results in high effluent turbidities (Jenkins, 2004). However, when conditions favoring the growth of filaments over floc-formers occur, a condition commonly referred to as filamentous "bulking" may occur.

Download or read book Activated Sludge written by Jiri Wanner and published by CRC Press. This book was released on 1994-11-24 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Filamentous bulking and foaming are the most frequent operational problems in activated sludge plants. This recent book provides a comprehensive, concise guide to the microbiological and technical aspects of bulking and foaming control. The result of over 25 years of research, the book stresses practical control measures based on kinetic and metabolic selection theories, as well as on case histories. Topics in the book include: biochemical processes in wastewater treatment, evaluation ofseparation problems, settling and foaming principles, bulking and foaming control methods, and system design. More than 100 tables and figures illustrate complex processes, and over 500 references provide a detailed compendium of available resources. It was the intention of the author to summarize in this book all essential pieces of information on both the microbiological and technical aspects of bulking and foaming control, so microbiologists and engineers can find new and helpful information from each other's field without studying vast numbers of primary literature sources. Naturally, the practical pieces of information required for solving practical operational problems are more stressed. The book is arranged into six major chapters which are subdivided into uniform topical sections. The reader interested in a particular problem or searching for a particular solution does not necessarily need to read the whole book to get the answer. There are many cross-references in the text which will lead the reader to the background of the problem, and to show its connection to similar problems and their solutions.
Book Synopsis Activated Sludge: Developments And Sustainable Solutions by : Nicholas F Gray
Download or read book Activated Sludge: Developments And Sustainable Solutions written by Nicholas F Gray and published by World Scientific. 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)

Book excerpt: From the book's introduction: This is not an introductory text about activated sludge. In this book, we discuss the observation, testing, and calculation procedures that provide data about the status of the activated sludge process. In addition, we discuss in depth how to apply this data to the business of controlling your activated sludge treatment process. Basic activated sludge concepts are addressed in this book in the context of process evaluation and control. We focus our efforts on discussing a basic, practical system of control for the process. The procedures discussed in this manual are equally applicable to all variations. An operator must have information about settleability, dissolved oxygen concentration, solids concentration, effluent quality, and clarifier sludge levels for consistent, efficient process performance of every type of activated sludge process. These procedures are covered in detail. The procedures discussed are based on work done by E. B. Mallory in the 1930's and 40's and further developed by Alfred W. West while he was head of the Operational Technology Branch of the Environmental Protection Agency in the 1960's and 70's. The system, with some modifications by this author, is frequently called the "West Method" or "Sludge Quality Method" of activated sludge process control because operational controls adjustments are based on the sludge quality existing in your facility rather than on arbitrary values.
