Download or read book Sequencing Batch Reactor SBR Technology for Biological Treatment of Sewage written by Chin Ming Lim and published by . This book was released on 2001 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sequencing batch reactor (SBR) has become popular in recent years since Irvine and Davis (1979) described its operation. The SBR achieved the processes in framework of space compared to the conventional system, which achieves in terms of space. There are generelly 5 operational steps in a SBR cycle namely Fill, React, Settle, Draw, and Idle. A bench scale SBR was studied at 2 difference strategies. The study was conducted at different cycle times (6h, 8h and 10h) and different operational mode based on the ratio of anaerobic period (1/2, 1/1, and 1.7/1). The study was undertaken to investigate the effiecient quality, removal efficiency, SVI and kinetic growth coefficient. Results from strategy A (different cycle time) showed that increase in cycle time ld to decrease in the removal of TSS, COD and BOD5. Best results were obtained for the system with the 6h-cycle time, followed by the 8h-cycle time and lastly was the 10h-cycle time. six hours cycle time was chosen for strategy B mainly due to the overall better removal efficiency on TSS, COD and BOD5. There were 3 operational modes being examined in strategy B, They were 1/2.7 ( longest aerobic period), 1/1 and 1.7/1 (shortest aerobic periods). Best results were obtained from the 1/2.7 operational mode with the longest aerobic (lowest Li, which was 1.22 mg/mg.d), followed by 1/1 operational mode and lastly was the 1.7/1 operational mode. The higher removal efficiency was associated with the longer aerobic period, the kinetic growth coefficient and SVI also increased with the increasing of aerobic period. Therefore, the 6h-cycle time and 1/2.7 operational mode appeared to be the most reliable option in this study. For further studies, more work could be done to have a better understanding of the SBR system. For instance, inclusion of an anoxic period in the React step would enhance denitrification process to achieved better effluent quality. Moreover, kinetic growth model can be further explored by thymidine assay.

Available in PDF, EPUB and Kindle. Book excerpt: The practical guide on what to do right when biological influences cause a sequencing batch reactor to go wrong This richly illustrated, straightforward guide carries forth the legacy established by previous editions in the Wiley Wastewater Microbiology series by focusing attention on the mixed gathering of organisms cohabitating within a sequencing batching reactor (SBR), and the key roles their biology plays in this wastewater processing tank's function. With a clear, user-friendly presentation of complex subject matter, Troubleshooting the Sequence Batch Reactor first teaches plant operators how to differentiate the positive and expected organismal dynamics present in optimal SBR performance from the negative and damaging ones that create unhealthy sludge, and a stoppage in SBR operations. Next, Troubleshooting the Sequence Batch Reactor delivers all the tools necessary to get an SBR back on track and running safely. In this book you'll get: Short-course situations tested by the author for the past fifteen years Accessible material aimed at operators instead of design and consulting engineers Essential information for understanding biological conditions such as aerobic, anoxic, and anaerobic/fermentative at the treatment process Examination of the properties of protozoa (single-celled) and metazoa (multi-celled) organisms, and their significance in wastewater treatment Devoid of overwhelming scientific jargon, chemical equations, and kinetics, this book simplifies details to provide quick instruction for plant operators on how to make more informed day-to-day process control decisions, how to troubleshoot confidently when SBR conditions become compromised, and how to act decisively when the problem is ultimately identified.

Download or read book Evaluation of Sequencing Batch Reactor Sewage Treatment Plants for First Nation Communities written by and published by . This book was released on 1994 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sequencing batch reactor (SBR) sewage treatment is an activated sludge process which treats a given volume of wastewater on a batch basis in a single reactor by a number of sequencing steps. The process eliminates the need for separate secondary clarifiers and sludge return pumps. This report was commissioned to verify the reported high performance of SBR systems in the US and Canada, with particular focus on Manitoba First Nations installations, and to be a compendium which would assist in transferring SBR technology to other First Nation communities across Canada. The report reviews the historical development of the SBR process; describes the various SBR technologies, their capabilities, and advantages over other mechanical biological wastewater treatment plants; and discussed operation and maintenance requirements. Guidance is provided on SBR plant design and on preliminary cost estimates. Appendices include process descriptions, equipment details, and process control procedures.
Download or read book Mechanism and Design of Sequencing Batch Reactors for Nutrient Removal written by Derin Orhon and published by IWA Publishing. This book was released on 2005-05-31 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sequencing batch reactor (SBR) is perhaps the most promising and viable of the proposed activated sludge modifications today for the removal of organic carbon and nutrients. In a relatively short period, it has become increasingly popular for the treatment of domestic and industrial wastewaters, as an effective biological treatment system due to its simplicity and flexibility of operation. Mechanism and Design of Sequencing Batch Reactors for Nutrient Removal has been prepared with the main objective to provide a unified design approach for SBR systems, primarily based on relevant process stoichiometry. Specific emphasis has been placed upon the fact that such a unified design approach is also by nature the determining factor for the selection of the most appropriate cyclic operation scheme, the sequence of necessary phases and filling patterns for the particular application. The proposed basis for design is developed and presented in a stepwise approach to cover both organic carbon and nutrient removal, domestic and industrial wastewaters, strong and specific wastes. The merits of model simulation as an integral complement of process design, along with performance evaluation of SBR models are also emphasized. Scientific and Technical Report No. 19

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.

Book excerpt: For information on the online course in Biological Wastewater Treatment from UNESCO-IHE, visit: http://www.iwapublishing.co.uk/books/biological-wastewater-treatment-online-course-principles-modeling-and-design Over the past twenty years, the knowledge and understanding of wastewater treatment have advanced extensively and moved away from empirically-based approaches to a first principles approach embracing chemistry, microbiology, physical and bioprocess engineering, and mathematics. Many of these advances have matured to the degree that they have been codified into mathematical models for simulation with computers. For a new generation of young scientists and engineers entering the wastewater treatment profession, the quantity, complexity and diversity of these new developments can be overwhelming, particularly in developing countries where access is not readily available to advanced level tertiary education courses in wastewater treatment. Biological Wastewater Treatment addresses this deficiency. It assembles and integrates the postgraduate course material of a dozen or so professors from research groups around the world that have made significant contributions to the advances in wastewater treatment. The book forms part of an internet-based curriculum in biological wastewater treatment which also includes: Summarized lecture handouts of the topics covered in book Filmed lectures by the author professors Tutorial exercises for students self-learning Upon completion of this curriculum the modern approach of modelling and simulation to wastewater treatment plant design and operation, be it activated sludge, biological nitrogen and phosphorus removal, secondary settling tanks or biofilm systems, can be embraced with deeper insight, advanced knowledge and greater confidence.
