This book presents a Two-Stage Anaerobic Digestion (TSAD) technique for producing hydrogen and methane, following a step-by-step approach in order to guide readers through the experimental verification of the related hypothesis. In the first stage of AD, the reaction conditions are optimized to obtain the maximum amount of hydrogen, while in the second the liquid residue from the first phase is used as a substrate to produce fuel-methane. AD has traditionally been used to reduce the organic content of waste; this results in a biogas that is primarily constituted of CH4 and CO2. Over the last few decades, the conversion of organic matter into hydrogen by means of AD and selecting Hydrogen Producing Bacteria (HPB) has matured into a viable and sustainable technology among the pallet of H2 generation technologies. The combined bio-production of hydrogen and methane from Organic Waste Materials (OWM) is considered to be an ideal way of utilizing waste, and can increase energy efficiency (the substrate Heat Value converted into H2 and CH4 fuel) to roughly 80%, since the energy efficiency of H2-production alone (15%) is not energetically competitive. The two gas streams can be used either separately or in combination (Hytane (R)), be supplied as civilian gas or used for transportation purposes. All the aspects of this sustainable technology are taken into account, from the basic biochemical implications to engineering aspects, establishing the design criteria and the scale-up procedures for full-scale application. The sustainability of the TSAD method is assessed by applying EROI (Energy Return On Investment) and EPT (Energy Payback Time) criteria, and both the general approach and application to the field of Anaerobic Digestion are illustrated.

This book encourages and demonstrates an innovative approach to the design and operation of urban wastewater systems: integrated modelling and control. Consideration of sewer system, wastewater treatment plant and receiving water body as a single system (rather than as three moderately independent units as before) opens up new types of analyses and new control algorithms for urban wastewater systems.After a comprehensive review of the literature of various fields including processes affecting water flow and quality in urban wastewater systems and their description by different types of models, this book also introduces some of the fundamental concepts of the operation of such systems. It discusses conventional as well as innovative control approaches - ranging from control by simple set-points to elaborate hierarchical control concepts taking into account the water flow and the quality of sewer systems, treatment plants and receiving water body. Thus it will enable the researcher as well as the practising engineer to analyse and to implement various types of control for a particular case study site. In order to illustrate the concepts developed, a detailed simulation study, covering the complete urban wastewater system, is presented. The conclusions drawn demonstrate that the application of innovative control concepts can lead to improved performance of wastewater systems.In addition, a comprehensive survey of mathematical optimisation methods is presented. This book can assist the practising engineer and the student to gain knowledge of all aspects of wastewater systems. To the researcher, this book provides a thorough survey of existing simulation and control concepts and inspiration for further work.

Every day throughout Britain, by road, by rail and by sea, there are large numbers of routine movements of radioactive cargo. Materials at all stages of the nuclear cycle, from uranium ore to nuclear waste, from nuclear warheads to radioactive isotopes used in medicine, are constantly on the move. In normal circumstances handling low-level material exposes workers to small doses of radiation, but a serious accident could lead to widespread contamination and to the major risk of additional deaths from cancer. The accident record is not good. There are repeated small accidents and many people believe that the major accident is simply waiting to happen. This book gives a thorough account of what is moved, by wham and far what purpose. It considers the risks, including that of terrorism, the safety record and the precautions. It also highlights the perils of the secrecy surrounding the industry: for example, local councils are responsible for coping with any accident, but are not told when or where nuclear movements are taking place. Martin Bond's careful work is a large step towards order in a chaotic industry. Originally published in 1992

Except in schoolboy jokes, the subject of human waste is rarely aired. We talk about water-related diseases when most are sanitation-related - in short, we don t mention the shit.A century and a half ago, a long, hot summer reduced the Thames flowing past the UK Houses of Parliament to a Great Stink, thereby inducing MPs to legislate sanitary reform. Today, another sanitary reformation is needed, one that manages to spread cheaper and simpler systems to people everywhere.In the byways of the developing world, much is quietly happening on the excretory frontier. In 2008, the International Year of Sanitation, the authors bring this awkward subject to a wider audience than the world of international filth usually commands. They seek the elimination of the Great Distaste so that people without political clout or economic muscle can claim their right to a dignified and hygienic place to go .Published with UNICEF

This Volume covers protocols for various applications in hydrocarbon microbiology, including those of interest for industrial processes, biocatalysis, lipid and biofuel production, bioproducts, or the human microbiome. It presents detailed protocols for the functional screening of enzymes acting on greasy molecules (i.e. lipases, esterases), including assays for enantioselective biocatalysts, as well as approaches for protein display technologies. Protocols for improving fuel quality and production of biofuel and lipids in different hosts (bacteria, algae, yeast) are also provided. The production of biogas from organic waste and its fermentation into value-added products such as polyhydroxyalkanoates is covered, as well as an in-vitro model of the gut microbiome for short-chain fatty acid metabolism and microbial diversity analyses. The applications presented are examples of the many potential applications in hydrocarbon and lipid microbiology, and many (i.e. protein-display technologies) will also be of interest in other research fields. Hydrocarbon and Lipid Microbiology Protocols There are tens of thousands of structurally different hydrocarbons, hydrocarbon derivatives and lipids, and a wide array of these molecules are required for cells to function. The global hydrocarbon cycle, which is largely driven by microorganisms, has a major impact on our environment and climate. Microbes are responsible for cleaning up the environmental pollution caused by the exploitation of hydrocarbon reservoirs and will also be pivotal in reducing our reliance on fossil fuels by providing biofuels, plastics and industrial chemicals. Gaining an understanding of the relevant functions of the wide range of microbes that produce, consume and modify hydrocarbons and related compounds will be key to responding to these challenges. This comprehensive collection of current and emerging protocols will facilitate acquisition of this understanding and exploitation of useful activities of such microbes.

The books currently available on this subject contain some elements of physical-chemical treatment of water and wastewater but fall short of giving comprehensive and authoritative coverage. They contain some equations that are not substantiated, offering empirical data based on assumptions that are therefore difficult to comprehend. This text brings together the information previously scattered in several books and adds the knowledge from the author's lectures on wastewater engineering.

Physical-Chemical Treatment of Water and Wastewater is not only descriptive but is also analytical in nature. The work covers the physical unit operations and unit processes utilized in the treatment of water and wastewater. Its organization is designed to match the major processes and its approach is mathematical. The authors stress the description and derivation of processes and process parameters in mathematical terms, which can then be generalized into diverse empirical situations. Each chapter includes design equations, definitions of symbols, a glossary of terms, and worked examples.

One author is an environmental engineer and a professor for over 12 years and the other has been in the practice of environmental engineering for more than 20 years. They offer a sound analytical mathematical foundation and description of processes. Physical-Chemical Treatment of Water and Wastewater fills a niche as the only dedicated textbook in the area of physical and chemical methods, providing an analytical approach applicable to a range of empirical situations
