This book was released on 2001-09-30 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anaerobic digestion processes for the treatment of wastewaters and sludges are well over 100 years old. The anaerobic process is a natural gasification process, producing very useful end-products. It has taken a long time to prove that these processes are useful tools in sustainable development. A breakthrough was the development of the Upflow Anaerobic Sludge Bed reactor by Professor Gatze Lettinga. This showed that the anaerobic process could be operated as a highly effective and high-rate wastewater treatment process, opening the way to its implementation under practical conditions. It has, so far, been a struggle to prove the feasibility of anaerobic treatment, despite the obvious advantages in energy consumption, sludge production, and required land area; its drawbacks, i.e. required effluent polishing, odours, sensitivity to toxic compounds, made potential users reluctant to choose anaerobic instead of the conventional aerobic systems. However, as shown by the contributions in this issue, intensive research has overcome most of these drawbacks. To celebrate the career of Professor Lettinga, leading experts on anaerobic digestion processes were invited to highlight the state-of-the-art and future developments in their specific fields of interest. Seminar topics included microbiology, treatment of industrial wastewaters, xenobiotics and extreme environments, the biological S-cycle, treatment of domestic wastewater and the history of anaerobic digestion. The selected 20 papers in these proceedings represent the state of the art of anaerobic digestion, highlighting its impacts and potentials. They also recognised the stimulating role of Professor Gatze Lettinga in this development and agree with him that anaerobic digestion's full potential is still unexploited.

Download or read book Resource Recovery from Water written by Ilje Pikaar and published by IWA Publishing. This book was released on 2022-02-15 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout history, the first and foremost role of urban water management has been the protection human health and the local aquatic environment. To this end, the practice of (waste-)water treatment has maintained a central focus on the removal of pollutants through dissipative pathways. Approaches like –in case of wastewater treatment- the activated sludge process, which make ‘hazardous things’ disappear, have benefitted our society tremendously by safeguarding human and environmental health. While conventional (waste-)water treatment is regarded as one of the greatest engineering achievements of the 20th century, these dissipative approaches will not suffice in the 21th century as we enter the era of the circular economy. A key challenge for the future of urban water management is the need to re-envision the role of water infrastructure, still holding paramount the safeguard of human and environmental health while also becoming a more proactive force for sustainable development through the recovery of resources embedded in urban water. This book aims (i) to explain the basic principles governing resource recovery from water (how much is there, really); (ii) to provide comprehensive overview and critical assessment of the established and emerging technologies for resource recovery from water, and (iii) to put resource recovery from water in a legal, economic (including the economy of scale of recovered products), social (consumer’s point of view), and environmental sustainability framework. This book serves as a powerful teaching tool at the graduate entry master level aiming to developing the next generation of engineers and experts and is also highly relevant for seasoned water professionals and practicing engineers.

Download or read book Current Advances in Anaerobic Digestion Technology written by Marcell Nikolausz and published by MDPI. This book was released on 2021-03-17 with total page 230 pages. 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.

This book was released on 2002-08-31 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomethanization of the Organic Fraction of Municipal Solid Wastes is a comprehensive introduction to both the fundamentals and the more practical aspects of the anaerobic digestion of organic solid wastes, particularly those derived from households, that is, the organic fraction of municipal solid wastes (OFMSW). It can be used as a textbook for specialized courses and also as a guide for practitioners. In the first part, the book covers the relevant aspects of anaerobic digestion (AD) of organic wastes. The fundamentals and kinetic aspects of AD are reviewed with particular emphasis on the aspects related to solid wastes. This introduction is necessary to have a comprehensive view of the AD process and to understand the practical principles as well as the origin of possible problems arising from the management of the process. Chapter 2 emphasizes the role of kinetics in designing the reactor, paying special attention to existing models, particularly the dynamic ones. Through this introduction, it is intended to facilitate the technology transfer from laboratory or pilot plant experiences to full-scale process, in order to implement improvements in current digesters. Laboratory methods are described for the analysis and optimization of reactor performance, such as methanogenic activity tests or experimental evaluation of the biodegradation kinetics of solid organic waste. The different reaction patterns applied to industrial reactors are outlined. Industrial reactors are classified in accordance with the system they use, pointing out advantages and limitations. Co-digestion, enabling the co-treatment of organic wastes of different origin in a more economically feasible way, is described in detail. Examples of co-digestion are given, with OFMSW as a base-substrate. Finally, full-scale co-digestion plants are discussed. Various types (mechanical, biological, physico-chemical) of pre-treatment to increase the biodegradability, and thus the yields of the process, are reviewed in detail. The use of the fermentation products of anaerobic digesters for biological nutrient removal processes in wastewater treatment plants is described. This constitutes an example of integrated waste management, a field in which both economic and technical advances can be achieved. Balances are given to justify the approach, and a full-scale case study is presented. The important topic of economics and the ecological advantages of the process are emphasized. The use of compost, the integration with composting technology, and advantages over other technologies are detailed in the framework of an environmental impact assessment of biowaste treatment. Finally, the anaerobic digestion of MSW in landfills is reviewed in detail, with emphasis on landfill process enhancement and strategies for its application.
