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.

Book Synopsis High-Solids Anaerobic Digestion of the Organic Fraction of Municipal Solid Waste State of the Art, Outlook in Florida, and Enhancing Methane Yields from Lignocellulosic Wastes by : Gregory Richard Hinds
Download or read book High-Solids Anaerobic Digestion of the Organic Fraction of Municipal Solid Waste State of the Art, Outlook in Florida, and Enhancing Methane Yields from Lignocellulosic Wastes written by Gregory Richard Hinds and published by . This book was released on 2015 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anaerobic digestion (AD) is a biotechnology that employs natural microbial metabolism under oxygen-free conditions to stabilize organic waste. AD has been shown to be the most environmentally sustainable technology for treating the organic fraction of municipal solid waste (ofMSW), as it allows for the recovery of energy and nutrients from the waste. AD of ofMSW also saves landfill space and reduces leachate generation and fugitive methane emissions from landfills. High-solids AD (HS-AD) technologies (those designed to process feedstocks with >15% total solids content) have been shown to yield additional benefits when compared with liquid AD (L-AD) for treating ofMSW, including reduced parasitic energy demands, reactor volume requirements, water usage, and excess leachate generation. These factors paired with increasingly stringent environmentally-driven legislation have resulted in the steady development of HS-AD technologies in Europe since the 1990s and the recent advancement of HS-AD in the United States. However, HS-AD implementation in the US is hindered by the low cost of landfilling and a general lack of regulatory drivers encouraging organics separation and recycling. The goal of this research was to contribute to accelerating the implementation and improving the efficiency of HS-AD technologies. The specific objectives were to: (i) assess the state of the art of HS-AD in Europe and the US and investigate trends in development; (ii) conduct a case study assessment of the outlook for implementation of HS-AD in the state of Florida; and (iii) investigate the potential to enhance methane (CH4) yields in HS-AD of lignocellulosic wastes through bioaugmentation with pulp and paper mill anaerobic sludge. Information sources for the assessment of the state of HS-AD in Europe and the US included “grey” and published literature and discussions with consultants and technology vendors.

This book was released on 2000-05-31 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last decade much progress has been made in anaerobic digestion of solid waste: advances in research and development, construction of new plants, more favourable legislation. Key features of this progress are reported in these proceedings. While the selected papers cover a wide range of work on 'solid' organic wastes, there is a particular focus on the organic fraction of Municipal Solid Waste (MSW). Many landfills are set to close and there is a significant increase in separate collection of MSW. Biological treatments can maximise recycling and recovery of its components; anaerobic digestion, with its high energy recovery and limited environmental impact, is frequently the most cost-effective of these treatments. The future of anaerobic digestion of solid wastes is increasingly seen in the integration of this unique unit process in overall sustainable waste treatment. In Life Cycle Analysis anaerobic digestion offers several interesting features: energy recovery (a particularly important factor in third world countries); and a significantly lower contribution to global warming. Problems remain (as for all types of wastes treatments), particularly concerning the fate of micro-pollutants and overall end-product quality, but anaerobic digestion offers major potential in the long-term environmental management. These proceedings offer an unrivalled authoritative view of the present and future of anaerobic digestion of solid waste.

Available in PDF, EPUB and Kindle. Book excerpt: As a solution to the problems of municipal solid waste management, anaerobic digestion possesses the optimal combination of volume reduction, probability of success and potential for both energy and resource recovery. An innovative application of anaerobic processes is the co-digestion of sewage sludge and the organic fraction of municipal solid waste (OFMSW). The purpose of this study is to evaluate the technical feasibility of this process in the context of typical Canadian solid waste. Lab-scale experiments were initially conducted using one litre batch bioreactors operated mesophilically (37$\sp\circ$C) and fed a mixture of primary sludge (RAW), thickened waste activated sludge (TWAS) and simulated OFMSW. To facilitate organics solubilization, three pretreatments were evaluated: thermal, alkaline and thermochemical. Using a central composite experimental design, two factors were studied, the total solids content of the feed and its particle size. For all three pretreatments, second order empirical models were developed with respect to common indicators of metabolic activity, namely, biogas production, biogas methane concentration, soluble chemical oxygen demand (COD) removal and total and volatile solids reduction.

Book Synopsis Post Treatments of Anaerobically Treated Effluents by : Vinay Kumar Tyagi
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.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Anaerobic co-digestion of organic fraction of municipal solid waste (OFMSW), with thickened waste activated sludge (TWAS) and primary sludge (PS) has the potential to enhance (biodegradation) of solid waste, increase longevity of existing landfills and lead to more sustainable development by improving waste to energy production. This study reports on mesophilic batch anaerobic biological methane potential (BMP) assays carried out with different concentrations and combinations (ratios) of OFMSW, TWAS (microwave (MW) pre-treated and untreated) and PS to assess digester stability and potential improved specific biodegradability and potential increased specific biogas production by digestion of OFMSW with PS and TWAS in various tri-substrate mixtures. Results indicated improvements in specific biogas production with concomitant improvements in COD and volatile solid (VS) removal for co-digestion of OMSW, TWAS and PS vs. controls. In terms of improvements in biogas production and digester stability the OFMSW:TWAS:PS:50:25:25 ratio with or without TWAS MW treatment was deemed best for further continuous digester studies. At a 15d HRT which is the regulatory policy in the province of Ontario for municipal mesophilic anaerobic TWAS:PS treatment, co-digestion of OFMSW:TWAS:PS, and OFMSW:TWASMW:PS resulted in a 1.38 and 1.46 fold relative improvement in biogas production and concomitant waste stabilization when compared to TWAS:PS and TWASMW:PS digestion at the same HRT and volumetric VS loading rate respectively. Treatment of OFMSW with PS and TWAS provides beneficial effects that could be exploited at MWWTP that are being operated at loading rates less than design capacity.

This book was released on 1994 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Essentially all of the biodegradable solids in the feedstock can be removed, and that biogas production levels of up to 6 liters per liter of active volume of the anaerobic reactor have been achieved. The principal advantages of this process are: (1) the recovery of biogas that can be used as a fuel for the production of energy and (2) the production of humus-like material that can be used as a high-quality soil amendment or as boiler fuel. The fact that a liquid waste stream that needs further treatments is not generated in this process is an another significant advantage. [Authors' abstract].

This book was released on 2022-01-10 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is a collection of scientific contributions that highlight how scientific and technological evolution can change the paradigm of organic waste as an environmental problem into a renewable resource of energy and materials. Numerous researchers and research institutions that are located in different countries with varying levels of socio-economic development and other traditions were involved in this work. The materials that were considered include household waste, including human excreta and those generated by typical urban activities. The organic waste was derived from the agro-industrial sector and from packaging labelled as being biodegradable. Problems related to the detoxification of aquatic plants are discussed and the use of these plants for their ability to produce biomethane is documented simultaneously. An organic waste management strategy that was developed in the Albania context is also presented and discussed. Anaerobic digestion is one of the most widely studied technologies in this field, and this process is responsible for the production of biogas or methane, even in fossil resource-rich countries. On the other hand, aerobic fermentation is considered for the degradation of very toxic organic substances that can be dissolved into aqueous solutions that aid in the recovery of valuable materials from electrical and electronic equipment that do not have further use. There are a wide range of arguments and experiences that support the use of waste as a resource through disposal with simultaneous energy enhancement and the production of new materials, thus limiting the use of non-renewable resources for more sustainable development for the benefit of future generations.
