With growing public pressure and increasingly stringent environmental legislation, the waste industry is now being called upon to develop more sustainable methods of dealing with refuse. Coupled with moves to reduce reliance on landfill as a disposal route, biological treatment will increasingly become adopted as a standard requirement for the vast majority of putrescible wastes. Biowaste and Biological Waste Treatment examines the present, and likely future, state of biological waste treatment. The book falls naturally into three parts. The first covers the nature of biowaste, waste treatment in general and the regulatory framework which governs it. The second looks at the technologies and approaches available, while the final part examines the various policy questions and local, social and economic factors which affect the implementation of biowaste initiatives.

Hazardous waste incineration technologies have been developed to meet the needs of a rapidly growing market that has been created by the proliferation of hazardous waste in modern society. These hazardous wastes are continuously produced as by-products of many industries. Vast stockpiles of hazardous or toxic wastes are currently residing in insecure landfills, thus imperiling our drinking water supplies. This handbook is written with the user in mind. An in-depth review of regulatory and technical requirements is presented with later sections regarding permitting and operation of incineration facilities. A comprehensive description of established and emerging incinerator technologies is included along with a number of alternatives. One of the key sections involves a detailed procedure for choosing an incinerator for a specific job, including engineering calculations and going through the bid process. Rationale for whether to buy or lease incineration equipment is included as well as details on trial burns, permitting strategies, and startup and operation of incinerators.

Emissions come from different products which have finally turned into waste. Wastes are simply discarded products and the design of a product can have a significant impact on the nature of the waste produced. This text attempts to show how to manage these different types of solid waste emissions.

The objective of this text is to provide information on mill tailings and mine waste, and to discuss current and future issues facing the mining and environmental communities.

Environmental concerns have pushed the decarbonisation of the European economy high on the EU political agenda. This has renewed old debates about the role of nuclear energy in the European economy and society that gravitate around the issues of nuclear safety and radioactive waste management (RWM). RWM carries many elements of technical complexity, scientific uncertainty and social value, which makes policy decisions highly controversial. Public participation is usually believed to improve these decisions, ease their implementation by solving substantial conflicts, and enhance trust and social acceptance. Drawing upon sources including Euratom and the OECD Nuclear Energy Agency, the author offers a detailed overview of public involvement in RWM in the EU, analysing the implementation of national policies through official programmes and the views of stakeholders from all Member States. This book highlights the key successes and challenges in the quest for greater participation in RWM, and extrapolates insights for other contested energy infrastructures and controversies in land use. This book will be of great relevance to students, scholars and practitioners with an interest in radioactive waste management, energy policy, and EU environmental politics and policy.

In the Eastern corridor of Northern region of Ghana, presence of high fluoride concentration in the groundwater has made many drilled boreholes unusable for drinking. Little is, however, known about the factors contributing to the occurrence of high fluoride in this part of Ghana and it's spatial distribution. Treatment of the fluoride-contaminated groundwater by adsorption is also hampered by the lack of suitable adsorbents that are locally available. Based on principal component analysis, and saturation indices calculations, this thesis highlights that, the predominant mechanisms controlling the fluoride enrichment probably include calcite precipitation and Na/Ca exchange processes, both of which deplete Ca from the groundwater, and promote the dissolution of fluorite. The mechanisms also include F-/OH- anion exchange processes, as well as evapotranspiration processes which concentrate the fluoride ions, hence increasing its concentration in the groundwater. Spatial mapping showed that the high fluoride groundwaters occur predominantly in the Saboba, Cheriponi and Yendi districts. The thesis further highlights that, modifying the surface of indigenous materials by an aluminium coating process, is a very promising approach to develop a suitable fluoride adsorbent. Aluminum oxide coated media reduced fluoride in water from 5. 0 +/- 0.2 mg/L to 1.5 mg/L (which is the WHO health based guideline for fluoride), in both batch and continuous flow column experiments in the laboratory. Kinetic and isotherm studies, thermodynamic calculations, as well as analytical results from Fourier Transform Infrared Spectroscopy and Raman spectroscopy, suggest the mechanism of fluoride adsorption onto aluminium oxide coated media involved both physisorption and chemisorption processes. Field testing in a fluoritic community in Northern Ghana showed that the adsorbent is also capable of treating fluoride-contaminated groundwater in field conditions, suggesting it is a promising defluoridation adsorbent. The adsorbent also showed good regenerability potential that would allow re-use, which could make it practically and economically viable. Additional research is, however, required to further increase the fluoride adsorption capacity of developed adsorbent.

Pollution of waterbodies and the environment by petroleum industry is of particular concern in Nigeria. This problem can be addressed by the application of constructed wetlands (CWs) which is a nature-based system that is simple to construct, have low operational and maintenance costs in terms of supply of energy and its periodic maintenance. The application of CWs in Nigeria for polishing of petroleum refinery wastewater is an unprecedented research. This PhD thesis focused on some specific objectives which were characterization of treated secondary refinery wastewater, design, construction, operation and monitoring of planted (T. latifolia, C. alternifolius and C. dactylon) and unplanted vertical subsurface flow, horizontal subsurface flow and hybrid CWs for the removal of suspended solids, nutrients, heavy metals, organic matter and organic pollutants. The CWs effectively treated the petroleum contaminated wastewater to effluent compliance limits. In this study, T. latifolia planted CWs had consistently higher removal efficiencies for all the measured parameters than C. alternifolius and C. dactylon planted CW systems. Therefore, in order to improve the wastewater quality discharged by Kaduna Refining and Petrochemical Company (KRPC) Nigeria, meet stringent guidelines and protect the recipient streams, installation of CWs at the effluent discharge point of KRPC is strongly recommended.

Interest in solid waste disposal has been growing since the early 1960s, when researchers emphasized the potential for solid waste to harbor pathogenic microorganisms. Since then, society has become more interested in the environmental impacts of solid waste treatment and disposal, and how biological processes are used to minimize these impacts. This new text provides a basic understanding of the unique microbial ecosystems associated with the decomposition of municipal solid waste (MSW). It addresses the challenges of sampling and assaying microbial activities in MSW and describes preferred methods. The decomposition of MSW under anaerobic conditions in landfills and digestors is described, as well as under aerobioconditions during composting. The Microbiology of Solid Wastes discusses the need to consider MSW as an integrated system of collection, recycling, treatment, and disposal. A better understanding of solid waste microbiology will contribute to safe and economical solid waste management. Microbiologists, environmental engineers, and solid waste managers will all find this a useful reference.

This work offers an accessible discussion of current and emerging separation processes used for waste minimization, showing how the processes work on a day-to-day basis and providing troubleshooting tips for equipment that doesn't function according to design specifications. It describes the fundamentals of over 30 processes, types of equipment available, vendors, and common problems encountered in operations with hazardous waste.

Discharge of nutrient rich wastewater causes eutrophication of surface water; therefore wastewater treatment before discharge is required. Wastewater stabilization ponds are low cost technology used by developing countries but not effective in nitrogen removal due to low nitrifier biomass in the water column. Introduction of surface area for attachment of nitrifiers has therefore been proposed. This thesis reports the performance of pilot scale wastewater stabilization ponds fitted with baffles. The effect of baffles on nitrogen removal under tropical and two operational conditions was investigated. Under TKN/BOD ratio of 0.67, the baffled ponds performed better in nitrogen removal than the control pond. Total nitrogen mass balances showed that nitrification-denitrification, algal uptake and sedimentation were principle nitrogen removal mechanisms in biofilm waste stabilization ponds This study shows the potential of biofilms in improving nitrogen removal in wastewater stabilization ponds. The BOD and TSS concentrations were sufficiently low to permit for reuse in irrigation. If the objective is reuse and optimization of resources, the effluents from the ponds had sufficient nitrogen content for use in agriculture.

Filamentous bulking and foaming are the most frequent operational problems in activated sludge plants. This recent book provides a comprehensive, concise guide to the microbiological and technical aspects of bulking and foaming control.
The result of over 25 years of research, the book stresses practical control measures based on kinetic and metabolic selection theories, as well as on case histories. Topics in the book include: biochemical processes in wastewater treatment, evaluation ofseparation problems, settling and foaming principles, bulking and foaming control methods, and system design. More than 100 tables and figures illustrate complex processes, and over 500 references provide a detailed compendium of available resources.
It was the intention of the author to summarize in this book all essential pieces of information on both the microbiological and technical aspects of bulking and foaming control, so microbiologists and engineers can find new and helpful information from each other's field without studying vast numbers of primary literature sources. Naturally, the practical pieces of information required for solving practical operational problems are more stressed.
The book is arranged into six major chapters which are subdivided into uniform topical sections. The reader interested in a particular problem or searching for a particular solution does not necessarily need to read the whole book to get the answer. There are many cross-references in the text which will lead the reader to the background of the problem, and to show its connection to similar problems and their solutions.

In addition, much of the text should be relevant to safety and health professionals in almost any industrial setting.

FROM THE PREFACE
Sanitary landfills are the most widely utilized method of solid waste disposal around the world. With increased use and public awareness of this method of disposal, there is much concern with respect to the pollution potential of the landfill leachate. Depending on the composition and extent of decomposition of the refuse and hydrological factors, the leachate may become highly contaminated. As leachate migrates away from a landfill, it may cause serious pollution to the groundwater aquifer as well as adjacent surface waters. There is growing concern about surface and groundwater pollution from leachate. Better understanding and prediction of leachate generation, containment, and treatment are needed.
This book contains a literature review of various methodologies that have been developed for prediction, generation, characterization, containment, control, and treatment of leachate from sanitary landfills. The contents of this book are divided into nine chapters. Each chapter contains theory and definition of the important design parameters, literature review, example calculations, and references.
Chapter 1 is devoted to basic facts of solid waste problems current status and future trends towards waste reduction and recycling. Chapter 2 provides a general overview of municipal solid waste generation, collection, transport, resource recovery and reuse, and disposal options. The current status of sanitary landfill design and operation, problems associated with the landfilling, and future trends are presented in Chapter 3. Methods of enhanced stabilization, recycling landfill space, methane recovery, and above grade landfilling, and closure and post closure care of completed landfills are also discussed in detail. Chapter 4 provides a general overview of Subtitle D regulations and its impact upon sanitary landfilling practices. Chapter 5 is devoted entirely to moisture routing and leachate generation mechanisms. Examples of calculation procedure for determining the leachate quantity produced at a landfill are presented. Chapter 6 is devoted to chemical characterization of leachate that changes over the life of the fill. Both theoretical and experimental results are provided to estimate the leachate quality. Chapter 7 provides leachate attenuation processes and mechanisms. Chapter 8 is devoted to leachate collection systems. Natural soil sealants, admixed materials and synthetic membranes, their effectiveness, and methods of installation and economics are fully discussed. Chapter 9 provides a detailed review of leachate treatment methodology. Kinetic coefficients and treatment plant design considerations are summarized for the sole purpose of assisting con- sultants to design leachate treatment facilities. Leachate treatment case histories and numerous process trains are presented for treating leachate from young landfill. The book also describes how the process train can be changed effectively as leachate quality changes with time.

Starting with sludge and scum characterization, this practical guide provides least cost methods of improving sludge quality, options for beneficial reuse, the costs of implementing those options, and case studies of sludge reuse programs around the country. From the pitfalls of site selection to pairing sludge products with their markets, this is a comprehensive resource for anyone working to establish a successful sludge reuse program. Each sludge processing option is presented in depth, including costs, operational difficulties, odor control, and application of the sludge product. The land application of liquid sludge, traditional and innovative methods of natural and mechanical dewatering, and lime stabilization processes are covered in detail. Composting options including aerated static pile composting, vermicomposting, windrow composting, and in-vessel composting are investigated. Sludge pelletizing processes and innovative technologies for sludge reuse are discussed, along with the Part 503 regulations.
