The manual can be used independantly but when used in combination with the CD-ROM, it makes a unique tool for process operators to diagnose and solve operational problems. It is also a valuable educational and training package for universities and post experience courses. Click here for more details about the CD-ROM Process stability and final effluent quality largely depend upon the composition of the biomass in an activated sludge plant. Operational problems such as bulking and scum formation occur when the wrong micro-organisms are dominating the sludge population. Microscopic sludge investigation is therefore essential for process control and stable plant operation. The manual outlines the theoretical framework, extensively illustrated with full-colour micrographs.

Download or read book Activated Sludge Separation Problems written by Valter Tandoi and published by IWA Publishing. This book was released on 2017-09-15 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Activated Sludge Separation Problems: Theory, Control Measures, Practical Experiences, Second Edition, describes the most common activated sludge separation problems and explains the main reasons for the growth of the different filamentous microorganisms in activated sludge. The book summarizes the identification techniques for important groups of activated sludge microorganisms both based on conventional microscopic analysis and using the biological molecular tools available today (FISH and PCR). This new edition, with 70% new and updated material, also provides explanation of basic activated sludge process principles and of parameters necessary for process control and operation. The theory of secondary clarifies is described to the extent necessary for understanding the construction and operation of secondary clarifiers. The activated sludge reactor and secondary clarifies are treated as one system and the interactions are explained. The wide range of experiences around the world is documented and the methods to avoid the proliferation of these organisms are presented and critically reviewed. Activated Sludge Separation Problems consists of six chapters, presenting up-to-date technical and scientific aspects of these processes. The new edition also features an extended list of literature references for further reading. The book will be a valuable help for students of environmental engineering, wastewater specialists, plant operators and designers of activated sludge plants. It is also useful for specialists in wastewater operation laboratories, especially for those studying activated sludge separation properties.

Download or read book Microscopic Examination of the Activated Sludge Process written by Michael H. Gerardi and published by Wiley-Interscience. This book was released on 2008-07-21 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A practical, hands-on guide to using the microscope to analyze activated sludge in wastewater treatment The microscope provides the wastewater treatment plant operator with a special tool for process control and troubleshooting of the activated sludge process. The operator can "read" the organisms and use them as "bioindicators" to determine if operational conditions are acceptable or not acceptable. Written for plant operators and technicians and avoiding unnecessary technical jargon, Microscopic Examination of the Activated Sludge Process explores and explains: Microscopy, including microscopic measurements and techniques Directions for preparing and applying microbiological stains and immobilizing agents and techniques for preparing wet mounts and smears How to identify various types of organisms, including: floc particles and foam; protozoa; rotifers; worms and worm-like organisms; crustaceans; filamentous organisms; and algae and fungi The collection, evaluation, and presentation of observations This straightforward guide includes figures, tables, worksheets, photomicrographs, and black-and-white drawings of many living, microscopic components of the activated sludge process. It equips plant operators and technicians to monitor, regulate, and troubleshoot the treatment processes and also serves as a valuable resource for research professionals and sanitary engineers in wastewater treatment.

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)

Download or read book Emerging Technologies in Wastewater Treatment written by Maulin P. Shah and published by CRC Press. This book was released on 2023-03-20 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emerging technologies in wastewater treatment plant is an ecological, profitable and natural technology designed to eliminate heavy metals, radionuclides, xenobiotic compounds, organic waste, pesticides, etc. from contaminated sites or industrial downloads through biological means. Since this technology is used in conditions on site, it does not physically disturb the site unlike conventional methods, that is, chemical or mechanical methods. In this technology, higher plants or microbes are used alone or in combination for the phytoextraction of heavy metals from sites contaminated with metals. Through microbial interventions, metals are immobilized or mobilized through redox conversions in contaminated sites. If they are mobilized, accumulating metal plants are placed to accumulate metals in their bodies. Next, metal-loaded plants are collected and recycled to reduce the volume of waste and then, disposed of as hazardous materials or used for the recovery of precious metals, if possible. In case of immobilization, metals are no longer available to be toxic to organisms. There are very few books published on the proposed theme. A good number of books have been published on environmental bioremediation, but the proposed book is a new and an innovative proposal specifically in wastewater treatment. Looking into the importance of emerging technologies in wastewater treatment research, the book will have a high and applicable value in industrial wastewater treatment research. Features: The book highlights the importance of emerging technologies in the wastewater treatment plant to clean up the environment from pollution caused by human activities. It assesses the potential application of several existing bioremediation techniques and introduces new emerging technologies. It is an updated vision of the existing emerging technologies in environmental bioremediation strategies with their limitations and challenges and their potential application to remove environmental pollutants. It also introduces the new trends and advances in environmental bioremediation with a thorough discussion of recent developments in this field. Highlights the importance of bioremediation to deal with the ever-increasing number of environmental pollutants.
