Available in PDF, EPUB and Kindle. Book excerpt: In 1998 for the first time IAWQ added its sponsorship to a workshop conference (the fifth) of the Latin American Anaerobic Digestion group. From small beginnings these events have grown rapidly, so that this 5th workshop-seminar was attended by over 300 delegates from most of Latin America and a dozen countries outside the region. They participated in a high-quality programme with round table and workshop sessions followed by 2 seminar days. From the papers presented 32 have been selected for these proceedings they cover: Microbiological aspects Kinetics Modelling Design and process control in anaerobic digestion Anaerobic treatment of high-and low-strength wastewaters Effluent and post-treatments Anaerobic digestion of toxic residues Anaerobic digestion of solid wastes Use and management of sludge Full scale experiences. These papers have arisen from the thriving interest in anaerobic treatment across Latin America, but in their presentation of advanced research and insightful practical experiences they will prove of great value to scientists and engineers worldwide who are working on anaerobic treatments of wastewater.

Download or read book Sustainable Treatment and Reuse of Municipal Wastewater written by Menahem Libhaber and published by IWA Publishing. This book was released on 2012-05-31 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: In many countries, especially in developing countries, many people are lacking access to water and sanitation services and this inadequate service is the main cause of diseases in these countries. Application of appropriate wastewater treatment technologies, which are effective, low cost (in investment and especially in operation and maintenance), simple to operate, proven technologies, is a key component in any strategy aimed at increasing the coverage of wastewater treatment. Sustainable Treatment and Reuse of Municipal Wastewater presents the concepts of appropriate technology for wastewater treatment and the issues of strategy and policy for increasing wastewater treatment coverage. The book focuses on the resolution of wastewater treatment and disposal problems in developing countries, however the concepts presented are valid and applicable anywhere and plants based on combined unit processes of appropriate technology can also be used in developed countries and provide to them the benefits described. Sustainable Treatment and Reuse of Municipal Wastewater presents the basic engineering design procedures to obtain high quality effluents by treatment plants based on simple, low cost and easy to operate processes. The main message of the book is the idea of the ability to combine unit processes to create a treatment plant based on a series of appropriate technology processes which jointly can generate any required effluent quality. A plant based on a combination of appropriate technology unit processes is still easy to operate and is usually of lower costs than conventional processes in terms of investment and certainly in operation and maintenance. Chapters in the book are organized in a practical and accessible way to: Demonstrate selected unit process of appropriate technology and provide the scientific basis, the equations and the parameters required to design the unit processes, with some innovations developed by the authors. Highlight design procedures for selected combined processes which are in use in developing countries. Propose an innovative Orderly Design Method (ODM), which is easy to follow by practicing engineers, using the equations and formulas developed, once the fundamentals of each unit and combined process have been established. Provide a numeric example for the basic design of each selected appropriate technology process for a city with a population of 20,000 using the ODM and an Excel program which will be provided to the readers for download from an online web page. This book is a valuable and practical resource for all wastewater treatment engineers in field and the operational managers of waste treatment facilities. Authors: Menahem Libhaber, PhD, Consulting Engineer to the World Bank and other institutions, Alvaro Orozco Jaramillo, MSc, Consulting Engineer to the World Bank, the Inter-American Development Bank, Biwater and other institutions in various countries.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Besides, dominant microbial communities in two lab-scale UASB reactors operated at mesophilic (35± 2 0C) and psychrophilic ( 10± 1 0C) temperatures and fed with synthetic domestic wastewater and raw domestic sewage were identified by FISH technique in combination with Confocal Scanning Laser Microscopy (CSLM). The variation in microbial diversity and alteration in granular structure were also investigated. Thus, in addition to classical operational parameters, process performances ofboth high rate anaerobic reactors treating low strength wastewater at different temperatures were evaluated by investigating the variations in microbial diversity . Results indicated around 82% average total chemical oxygen demand (CODtoJ removal at around 1 1 0C (psychrophilic) at an organic loading rate (OLR) of 2 kgCOD/m3.day while at the same OLR around 90% average CODtot removal was observed at 35°C (mesophilic) in synthetic sewage treatment. On the other hand, average CODtot removals were obtained as 49% and 35% for the mesophilic and psychrophilic UASB reactors treating raw domestic sewage, respectively at an OLR around 0. 7 kgCOD/m3.day. Low removal efficiencies during raw domestic sewage treatment could be due to high amounts of sea water additions into the sewerage system that caused dilute influent concentrations during sampling periods. Results also indicated that the use of 16S rRNA-targeted probes, was well suited to the study of the microbial ecology in anaerobic treatment systems and Methanosaeta were found as the dominant species in both types of granules.
Download or read book Biogas Energy written by Tasneem Abbasi and published by Springer Science & Business Media. This book was released on 2011-11-03 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the importance of biogas energy has risen manifold and has become universal. This is due to the realization that biogas capture and utilization has great potential in controlling global warming. By capturing biogas wherever it is formed, we not only tap a source of clean energy, but we also prevent the escape of methane to the atmosphere. Given that methane has 25 times greater global warming potential than CO2, methane capture through biogas energy in this manner can contribute substantially towards global warming control.

Download or read book Removal of Chemical Oxygen Demand in Anaerobic Reactors Treating Low Strength Wastewater at Psychrophilic Temperatures written by Stephen Christopher Brown and published by . This book was released on 2014 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aerobic wastewater treatment is an energy intensive process that requires 1,322 kWh per million gallons of wastewater treated by the activated sludge process. As energy prices continue to climb, there will be increased pressure on industry to reduce energy consumption to mitigate costs. There is currently a growing interest in the application of anaerobic treatment to domestic wastewater as an alternative to the traditional activated sludge process. Challenges encountered with anaerobic treatment of domestic wastewater are longer acclimation times, and reactor instability. This study assessed the possibility of acclimating high-quality seed sludge to treat dilute domestic wastewater at ambient laboratory temperatures (18-24°C). Seed sludge acquired from a brewery wastewater treatment plant was acclimated in an anaerobic sequencing batch reactor (ASBR) within six weeks using two different methods. The acclimated sludge reached COD removals between 60-70% in ASBR mode. The acclimated sludge was then tested for COD reduction in an upflow anaerobic sludge bed (UASB) reactor and compared to a more concentrated unacclimated sludge. Maximum COD removals in the UASB operational phase were 67% for the acclimated sludge and 74% for the unacclimated sludge. The performance of the anaerobic sludge bed reactors (UASB) were modeled indicated good correlation with the Grau second-order model and the modified Stover-Kincannon model. The results of this study indicate the ability to acclimate biomass in both ASBR and UASB reactors to treat low-strength (
Download or read book Aerobic Granular Sludge written by S. Bathe and published by IWA Publishing. This book was released on 2005-03-31 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aerobic Granular Sludge has recently received growing attention by researchers and technology developers, worldwide. Laboratory studies and preliminary field tests led to the conclusion that granular activated sludge can be readily established and profitably used in activated sludge plants, provided 'correct' process conditions are chosen. But what makes process conditions 'correct'? And what makes granules different from activated sludge flocs? Answers to these question are offered in Aerobic Granular Sludge. Major topics covered in this book include: Reasons and mechanism of aerobic granule formation Structure of the microbial population of aerobic granules Role, composition and physical properties of EPS Diffuse limitation and microbial activity within granules Physio-chemical characteristics Operation and application of granule reactors Scale-up aspects of granular sludge reactors, and case studies Aerobic Granular Sludge provides up-to-date information about a rapidly emerging new technology of biological treatment.
Download or read book Post Treatments of Anaerobically Treated Effluents written by Vinay Kumar Tyagi and published by IWA Publishing. This book was released on 2019-06-15 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: The anaerobic process is considered to be a sustainable technology for organic waste treatment mainly due to its lower energy consumption and production of residual solids coupled with the prospect of energy recovery from the biogas generated. However, the anaerobic process cannot be seen as providing the ‘complete’ solution as its treated effluents would typically not meet the desired discharge limits in terms of residual carbon, nutrients and pathogens. This has given impetus to subsequent post treatment in order to meet the environmental legislations and protect the receiving water bodies and environment. This book discusses anaerobic treatment from the perspective of organic wastes and wastewaters (municipal and industrial) followed by various post-treatment options for anaerobic effluent polishing and resource recovery. Coverage will also be from the perspective of future trends and thoughts on anaerobic technologies being able to support meeting the increasingly stringent disposal standards. The resource recovery angle is particularly interesting as this can arguably help achieve the circular economy. It is intended the information can be used to identify appropriate solutions for anaerobic effluent treatment and possible alternative approaches to the commonly applied post-treatment techniques. The succeeding discussion is intended to lead on to identification of opportunities for further research and development. This book can be used as a standard reference book and textbook in universities for Master and Doctoral students. The academic community relevant to the subject, namely faculty, researchers, scientists, and practicing engineers, will find the book both informative and as a useful source of successful case studies.
Download or read book A B processes Towards Energy Self sufficient Municipal Wastewater Treatment written by Yu Liu and published by IWA Publishing. This book was released on 2019-11-15 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: The principle of the conventional activated sludge (CAS) for municipal wastewater treatment is primarily based on biological oxidation by which organic matters are converted to biomass and carbon dioxide. After more than 100 years’ successful application, the CAS process is receiving increasing critiques on its high energy consumption and excessive sludge generation. Currently, almost all municipal wastewater treatment plants with the CAS as a core process are being operated in an energy-negative fashion. To tackle such challenging situations, there is a need to re-examine the present wastewater treatment philosophy by developing and adopting novel process configurations and emerging technologies. The solutions going forward should rely on the ways to improve direct energy recovery from wastewater, while minimizing in-plant energy consumption. This book begins with a critical overview of the energy situation and challenges in current municipal wastewater treatment plants, showing the necessity of the paradigm shift from removal to recovery in terms of energy and resource. As such, the concept of A-B process is discussed in detail in the book. It appears that various A-B process configurations are able to provide possible engineering solutions in which A-stage is primarily designed for COD capture with the aim for direct anaerobic treatment without producing excessive biosludge, while B-stage is designated for nitrogen removal. Making the wastewater treatment energy self-sustainable is obviously of global significance and eventually may become a game changer for the global market of the municipal wastewater reclamation technology. The principal audiences include practitioners, professionals, university researchers, undergraduate and postgraduate students who are interested and specialized in municipal wastewater treatment and process design, environmental engineering, and environmental biotechnology.
