Book Synopsis Activated Sludge by : Wesley Eckenfelder
Download or read book Activated Sludge written by Wesley Eckenfelder and published by CRC Press. This book was released on 1998-03-11 with total page 314 pages. Available in PDF, EPUB and Kindle. 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)
Book Synopsis Settleability Problems and Loss of Solids in the Activated Sludge Process by : Michael H. Gerardi
Download or read book Settleability Problems and Loss of Solids in the Activated Sludge Process written by Michael H. Gerardi and published by John Wiley & Sons. This book was released on 2003-06-17 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: The activated sludge process is the most versatile, commonly used wastewater treatment system in North America; however, many activated sludge processes frequently experience operational problems related to poor compaction or settleability of secondary solids and loss of secondary solids from the clarifier. Eschewing the technical jargon and copious chemical equations found in the majority of wastewater studies, Settleability Problems and Loss of Solids in the Activated Sludge Process speaks directly to plant operators, showing them how to identify and solve common problems and achieve maximum efficiency. Michael H. Gerardi’s hands-on guide addresses the most common plant operational problems, such as increased costs, loss of treatment efficiency, and permit violations. Using numerous tables and illustrations, Settleability Problems provides microscopic and analytical techniques for troubleshooting and identifying the conditions responsible for settleability problems and loss of solids. It includes pictures of wet mounts and smears of acceptable and unacceptable microscopic conditions of the activated sludge and presents corrective measures for operational problems. Chapters include: Undesired Filamentous Growth Nutrient-Deficient Floc Particles Denitrification Slug Discharge of Soluble cBOD Viscous Bulking or Zoogloeal Growth Production and Accumulation of Foam and Scum Volume II in the series, Settleability Problems will prove to be of unparalleled value to wastewater treatment plant operators as well as students of wastewater microbiology.

This book was released on 1982 with total page 706 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the introduction of pure oxygen activated sludge systems in the late 1960's, proponents have claimed several advantages resulting from the elevated dissolved oxygen (DO) levels maintained. However, numerous comparative studies have failed to produce a consensus of professional opinion regarding the validity of these claimed advantages. The purpose of this study was to evaluate fundamental theories that might explain the effects of elevated DO levels, to assess the validity of claimed advantages for pure oxygen systems, and to provide guidance regarding appropriate DO levels in activated sludge systems. A literature review revealed that dispersed bacterial cells respond to DO, as measured by respiration rate or intracellular concentrations of metabolites, only at very low concentrations (less than about 0.1 mg/1). Consequently, the occurrence of oxygen diffusional limitations in large bacterial floc and the development of an anoxic core was preliminarily identified as the only reasonable theory for explaining effects of high DO levels. The first phase of this study involved the development of dispersed bacterial cultures in chemostats. Results indicated no significant difference in yield, kinetic coefficients, or specific ATP content between chemostats operated at a low DO level (2.0 mg/1) and a high DO level (15 mg/1). These results confirmed that differences in activated sludge characteristics that apparently result from the maintenance of high DO levels can only be attributed to diffusional limitations. The second phase of this research utilized laboratory-scale activated sludge systems. A simple respirometric procedure was utilized to evaluate the response of respiration rate to DO concentration for these flocculant cultures and plots of specific respiration rate versus DO concentration were developed. These curves were subsequently described in terms of the DO at which the respiration rate was 50 percent of the maximum (C° 5) and the DO at which the respiration rate first reached the maximum (Co). Values for C o 0.5 ranged up to about 1.0 mg/1 and for Co up to about 10 mg/1 for culture samples with maximum floc diameters of 1200 microns and respiration rates up to 200 mg 02/g TSS-hr. The final phase of this research involved respirometric tests on mixed liquor samples obtained from three full-scale activated sludge plants, Results indicated that the critical DO (Co) was typically less than 1.5 mg/1, even at higher respiration rates resulting from the treatment of high-strength industrial wastewaters. Floc size measurements indicated that flocs in full-scale plants rarely exceed 300 microns in diameter. It was concluded that oxygen diffusional limitations typically do not occur at full-scale activated sludge plants if aeration basin DO concentrations are maintained above about 1.0 mg/l.
