Distribution network control for water supply systems is considered, along with telemetry control systems and integrated data systems. The final chapter describes an automatic measuring device which uses a computer and image processing technology for measuring the length of filamentous microorganisms in activated sludge. This monograph will be a useful resource for engineers and those concerned with water pollution control.

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 Applications of Activated Sludge Models written by Damir Brdjanovic and published by IWA Publishing. This book was released on 2015-02-15 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1982 the International Association on Water Pollution Research and Control (IAWPRC), as it was then called, established a Task Group on Mathematical Modelling for Design and Operation of Activated Sludge Processes. The aim of the Task Group was to create a common platform that could be used for the future development of models for COD and N removal with a minimum of complexity. As the collaborative result of the work of several modelling groups, the Activated Sludge Model No. 1 (ASM1) was published in 1987, exactly 25 years ago. The ASM1 can be considered as the reference model, since this model triggered the general acceptance of wastewater treatment modelling, first in the research community and later on also in practice. ASM1 has become a reference for many scientific and practical projects, and has been implemented (in some cases with modifications) in most of the commercial software available for modelling and simulation of plants for N removal. The models have grown more complex over the years, from ASM1, including N removal processes, to ASM2 (and its variations) including P removal processes, and ASM3 that corrects the deficiencies of ASM1 and is based on a metabolic approach to modelling. So far, ASM1 is the most widely applied. Applications of Activated Sludge Models has been prepared in celebration of 25 years of ASM1 and in tribute to the activated sludge modelling pioneer, the late Professor G.v.R. Marrais. It consists of a dozen of practical applications for ASM models to model development, plant optimization, extension, upgrade, retrofit and troubleshooting, carried out by the members of the Delft modelling group over the last two decades.

Download or read book Digital Control Systems written by R. Isermann and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 583 pages. Available in PDF, EPUB and Kindle. Book excerpt: The great advances made in large-scale integration of semiconductors, the resulting cost-effective digital processors and data storage devi ces, and the development of suitable programming techniques are all having increasing influence on the techniques of measurement and con trol and on automation in general. The application of digital techni ques to process automation started in about 1960 when the first process computer was installed. From about 1970 computers have become standard equipment for the automation of industrial processes, connected on-line in open or closed loop. The annual increase of installed process compu ters in the last decade was about 20- 30 %. The cost of hardware has shown a tendency to decrease, whereas the relative cost of user soft ware has tended to increase. Because of the relatively high total cost, the first phase of digital computer application to process control is characterized by the centralization of many functions in a single (though sometimes in several) process computer. Such centralization does not permit full utilization of the many advantages of digital signal processing and rapid economic pay-off as analog back-up systems or parallel standby computers must often be provided to cover possible breakdowns in the central computer. In 1971 the first microprocessors were marketed which, together with large-scale integrated semiconductor memory units and input/output mo dules, can be assembled into more cost-effective process microcompu ters.

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.

Download or read book Benchmarking of Control Strategies for Wastewater Treatment Plants written by Krist V. Gernaey and published by IWA Publishing. This book was released on 2014-09-15 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wastewater treatment plants are large non-linear systems subject to large perturbations in wastewater flow rate, load and composition. Nevertheless these plants have to be operated continuously, meeting stricter and stricter regulations. Many control strategies have been proposed in the literature for improved and more efficient operation of wastewater treatment plants. Unfortunately, their evaluation and comparison – either practical or based on simulation – is difficult. This is partly due to the variability of the influent, to the complexity of the biological and biochemical phenomena and to the large range of time constants (from a few minutes to several days). The lack of standard evaluation criteria is also a tremendous disadvantage. To really enhance the acceptance of innovative control strategies, such an evaluation needs to be based on a rigorous methodology including a simulation model, plant layout, controllers, sensors, performance criteria and test procedures, i.e. a complete benchmarking protocol. This book is a Scientific and Technical Report produced by the IWA Task Group on Benchmarking of Control Strategies for Wastewater Treatment Plants. The goal of the Task Group includes developing models and simulation tools that encompass the most typical unit processes within a wastewater treatment system (primary treatment, activated sludge, sludge treatment, etc.), as well as tools that will enable the evaluation of long-term control strategies and monitoring tasks (i.e. automatic detection of sensor and process faults). Work on these extensions has been carried out by the Task Group during the past five years, and the main results are summarized in Benchmarking of Control Strategies for Wastewater Treatment Plants. Besides a description of the final version of the already well-known Benchmark Simulation Model no. 1 (BSM1), the book includes the Benchmark Simulation Model no. 1 Long-Term (BSM1_LT) – with focus on benchmarking of process monitoring tasks – and the plant-wide Benchmark Simulation Model no. 2 (BSM2).
