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.

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.
Download or read book Guidelines for Using Activated Sludge Models written by Leiv Rieger and published by IWA Publishing. This book was released on 2012-09-14 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mathematical modelling of activated sludge systems is used widely for plant design, optimisation, training, controller design and research. The quality of simulation studies varies depending on the project objectives, finances and expertise available. Consideration has to be given to the model accuracy and the amount of time required carrying out a simulation study to produce the desired accuracy. Inconsistent approaches and insufficient documentation make quality assessment and comparison of simulation results difficult or almost impossible. A general framework for the application of activated sludge models is needed in order to overcome these obstacles. The genesis of the Good Modelling Practice (GMP) Task Group lies in a workshop held at the 4th IWA World Water Congress in Marrakech, Morocco where members of research groups active in wastewater treatment modelling came together to develop plans to synthesize the best practices of modellers from all over the world. The most cited protocols were included in the work, amongst others from: HSG (Hochschulgruppe), STOWA, BIOMATH and WERF. The goal of the group is to set up an internationally accepted framework to deal with the ASM type models in practice. This framework shall make modelling more straightforward and systematic to use especially for practitioners and consultants. Additionally, it shall help to define quality levels for simulation results, a procedure to assess this quality and to assist in the proper use of the models. The framework will describe a methodology for goal-oriented application of activated sludge models demonstrated by means of a concise guideline about the procedure of a simulation study and some illustrative case studies. The case studies shall give examples for the required data quality and quantity and the effort for calibration/validation with respect to a defined goal. The final report will include an extended appendix with additional information and details of methodologies. Additional features in Guidelines for Using Activated Sludge Models include a chapter on modelling industrial wastewater, an overview on the history, current practice and future of activated sludge modelling and several explanatory case studies. It can be used as an introductory book to learn about Good Modelling Practice (GMP) in activated sludge modelling and will be of special interest for process engineers who have no prior knowledge of modelling or for lecturers who need a textbook for their students. The STR can also be used as a modelling reference book and includes an extended appendix with additional information and details of methodologies. Scientific and Technical Report No. 22

Download or read book Activated Sludge Wastewater Treatment written by Eric Wahlberg and published by . This book was released on 1918-12-17 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a milestone in the evolution of wastewater treatment operations. It explains the science of treatment framed within an ethics where wastewater personnel are seen as protectors of public health, preservers of the environment, and stewards of public monies. Written by a former plant operator with a Ph.D., the book presents the fundamental science behind the unit processes in wastewater treatment plants, including biological nutrient removal. In so doing, it challenges longstanding operational doctrines enshrined by habit and tradition, such as being careful not to remove too many influent organics in a primary clarifier for fear of starving the microorganisms in the aeration basin, or using the MLSS concentration to control effluent quality, or cutting the growth rate of microorganisms in anticipation of their slower growth rate in winter. Dispelling much of the prevailing that's-the-way-we've-always-done-it dogma is achieved through an elegant and understandable presentation of the biology, chemistry, and physics that explain the phenomena of wastewater treatment. At the same time, the book is intensely practical. It offers detailed and data-based process control solutions to stabilize plant performance, maintain consistent effluent quality, and reduce energy costs. Powerful, easily implemented statistical techniques are given to unlock the meaning of plant performance data and make informed process control decisions. The book's approach is learning-focused, including numerous examples of a failsafe, foolproof arithmetical method that enables operations professionals to define, set up, and solve problems.
Download or read book Nitrification and Denitrification in the Activated Sludge Process written by Michael H. Gerardi and published by John Wiley & Sons. This book was released on 2002-01-09 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrification and Denitrification in the Activated Sludge Process, the first in a series on the microbiology of wastewater treatment, comprises the critical topics of cost-effective operation, permit compliance, process control, and troubleshooting in wastewater treatment plants. Avoiding the technical jargon, chemical equations, and kinetics that typically accompany such texts, Nitrification and Denitrification in the Activated Sludge Process directly addresses plant operators and technicians, providing necessary information for understanding the microbiology and biological conditions that occur in the treatment process. Of special interest to wastewater treatment plant operators are the bacteria that degrade nitrogenous wastes–the nitrifying bacteria–and the bacteria that degrade carbonaceous wastes–the cBOD-removing bacteria. Both groups of bacteria need to be routinely monitored and operational conditions favorably adjusted to ensure desired nitrification. Each chapter in this groundbreaking study offers a better understanding of the importance of nitrification and denitrification and the bacteria involved in these crucial processes. Chapters include: Organotrophs The Wastewater Nitrogen Cycle Nitrite Ion Accumulation Dissolved Oxygen Denitrifying Bacteria Gaseous End Products Free Molecular Oxygen The Occurrence of Denitrification

Available in PDF, EPUB and Kindle. Book excerpt: Spellman's Standard Handbook for Wastewater Operators Volume 1 Fundamental-Level provides information and unit process trouble-shooting guidance required on a daily basis, not only by the plant manager, plant superintendent, chief operator, lab technician, maintenance operator, but more importantly by and for the plant operator, and those in preparation for taking the entry-level Class IV/Class III or Grade I/II operator examinations. This handbook was prepared to help operators obtain licensing and to operate wastewater treatment plants properly. It can be used as a textbook in technical training courses in technical schools and at the junior college level. Spellman's Standard Handbook for Wastewater Operators is the first volume of a new study guide and readily accessible source of information for review in preparing wastewater personnel for operator certification and licensure. These handbooks are resource manuals and troubleshooting guides that contain wastewater treatment information, data, operational material, process control procedures and problem solving, safety and health information, new trends in wastewater treatment administration and technology, and numerous sample problem-solving practice sets, many based on actual tests. The Handbooks' goal is to enhance the understanding, awareness and abilities of practicing operators and those who want to become operators. The three volumes are designed to build on each other, providing increasingly advanced information. For persons preparing for operator's licensing, this is critical, because wastewater treatment is a complex process. For licensed veteran operators, continuous review is also critical, because wastewater treatment is an evolving, dynamic, ever-changing field. Spellman's Standard Handbooks provide the vehicle for reaching these goals.
