Available in PDF, EPUB and Kindle. Book excerpt: "Waste activated sludge is commonly treated through anaerobic digestion (AD) in wastewater treatment plants to reduce the amount of solids waste to handle and recover energy. AD reactors are typically operated at a temperature higher than ambient to increase the kinetics of the rate-limiting step in AD process. However, since heating takes up a considerable proportion of the recovered energy, and waste disposal accounts for a substantial portion the operation budget, many pretreatment and operational methods have been developed to enhance the biosolids re-duction and potentially improve the energy recovery. One of the least investigated strategy to improve energy recovery is to reduce the operation temperature of AD once the pretreatment is applied to the waste activated sludge. This is the topic of the study in this thesis. This thesis investigated the improvement in the performance of the digestion of ozonated waste activated sludge at 15°C and room temperature (22.6±0.3°C) with the addition of zero-valent iron (ZVI) and the separation of the digester in a two-stage process. The experimental period was divided into two phases. In Phase I, a high-rate single-stage process was applied to three 4-L reactors at two different temperatures (one at 15°C and two at room temperature). ZVI pow-der was added to the 15°C and one of the two reactors at room temperature. By comparing the performance of the ZVI-free reactor (control), the effect of ZVI on pre-ozonated AD was evalu-ated. In Phase II, both reactors receiving ZVI in Phase I were transformed into two-stage diges-tion systems (i.e., fermentation reactor followed by a methanogenic reactor), while the other operation parameters (ZVI dosage, temperature, and ozone dose to the WAS) remained the same. Results obtained over 278 days of operation revealed that the addition of ZVI in Phase I increased the biogas production by 24% when operating at room temperature and increased the proportion of biomethane in the biogas from 65% to 74%. These improvements were associated with the more efficient conversion of hydrolyzed chemical oxygen demand (COD) into bio-methane because the volatile suspended solids (VSS) destruction did not significantly change. In Phase II, ZVI-dosed two-stage anaerobic digestion showed an increase in specific methane production of 5% at 15°C and 14% at room temperature compared to the same reactors in Phas-es I. These improvements were only slightly higher than the changes in the average perfor-mance of the control reactor (single-stage ZVI-free reactor at room temperature), which rec-orded an increase in specific methane production of 3%. In conclusion, ZVI addition improved the biomethane production of anaerobic digestion at low temperatures, but its effect on solids reduction was limited. Conversely, staging did not appear to provide clear additional benefits to the process. This work will contribute to the optimization of energy recovery from anaerobic digestion, and may provide new avenues to enhance the process performance for small process-es that are more sensitive to the impacts of environmental conditions"--

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 Anaerobic Biodigesters for Human Waste Treatment written by Mukesh Kumar Meghvansi and published by Springer Nature. This book was released on 2022-08-21 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: The edited book brings out a comprehensive synthesis of latest scientific literature covering various important aspects of anaerobic biodigesters for human waste management that ranges from latest understanding on fundamental concepts/mechanisms of anaerobic biodigestion, modern tools and techniques used in process evaluation, current strategies being recruited for the performance enhancement, and case studies/ success stories across the world on applications of biodigesters used in human waste treatment. The anaerobic biodigestion is a process of break-down of organic waste by anaerobic microorganisms in absence of the oxygen. This process has been conventionally used for treating various types of organic waste including sewage sludge. After optimizing various process parameters, researchers have developed anaerobic biodigesters that have been successfully used for human waste (nigh soil) treatment. The topic of human waste treatment assumes global significance in the wake of UN sustainable Development Goals (SDG) wherein SDG-6 specifically highlights the Sanitation for all by 2030. The anaerobic Biodigester technology has the potential to manage the human waste as well and can contribute immensely in achieving targets of UN-SDG-6. This book is of interest to researchers, academicians, scientists, policy officials and capacity builders. Also the book serves as additional reading material for undergraduate and graduate students of environmental Biotechnology. National and international biotechnologists, environmental engineers and sanitation experts also find this to be a useful read.

Available in PDF, EPUB and Kindle. 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.

Available in PDF, EPUB and Kindle. Book excerpt: Anaerobic digestion (AD) is one of the oldest biotechnological processes and originally referred to biomass degradation under anoxic conditions in both natural and engineered systems. It has been used for decades to treat various waste streams and to produce methane-rich biogas as an important energy carrier, and it has become a major player in electrical power production. AD is a popular, mature technology, and our knowledge about the influencing process parameters as well as about the diverse microbial communities involved in the process has increased dramatically over the last few decades. To avoid competition with food and feed production, the AD feedstock spectrum has constantly been extended to waste products either rich in recalcitrant lignocellulose or containing inhibitory substances such as ammonia, which requires application of various pre-treatments or specific management of the microbial resources. Extending the definition of AD, it can also convert gases rich in hydrogen and carbon dioxide into methane that can substitute natural gas, which opens new opportunities by a direct link to traditional petrochemistry. Furthermore, AD can be coupled with emerging biotechnological applications, such as microbial electrochemical technologies or the production of medium-chain fatty acids by anaerobic fermentation. Ultimately, because of the wide range of applications, AD is still a very vital field in science. This Special Issue highlights some key topics of this research field.
