Radioactive wastes resulting from over 40 years of production of nuclear weapons in the U. S. are currently stored in 273 underground tanks at the U. S. Department of Energy Hanford site, Idaho National Engineering and Environmental Laboratory, Oak Ridge Reservation, and Savannah River site. Combined, tanks at these sjtes contain approximately 94,000,000 gallons of waste in a variety of forms including liquid, concrete-like salt cake, and various sludges. More than 730,000,000 curies of several radioactive isotopes are present in the underground tanks. Certainly, one of the greatest challenges facing the U. S. Department of Energy is how to characterize, retrieve, treat, and immobilize the great variety of tank wastes in a safe, timely, and cost-effective manner. For several years now, the U. S. Department of Energy has initiated and sponsored scientific and engineering studies, tests, and demonstrations to develop the myriad of technologies required to dispose of the radioactive tank wastes. In recent times, much of the Department of Energy R&D activities concerning tank wastes have been closely coordinated and organized through the Tanks Focus Area (IF A); responsibility for technical operations of the TF A has been assigned to the Pacific Northwest National Laboratory.

Our rivers and lakes are continuously self-purifying thanks to algal and bacterial biofilms that grow over the surface of stones and other debris. This same process has been employed for over a century to treat our municipal and industrial wastewater in specially designed fixed film reactors that maximize this microbial activity by providing ideal growth conditions and unlimited food and oxygen. Fixed film, or attached biofilm, reactors are unique in their ability to treat complex wastewaters and shock loadings; using far less energy than other wastewater treatment processes such as activated sludge, making them a sustainable treatment option.Targeted at undergraduate and postgraduate engineers and scientists, this book follows the structure of bestseller Biology of Wastewater Treatment. This volume gives an expanded and up-to-date overview of the use of fixed-film reactors in wastewater treatment with content spanning from biofilm formation, to traditional trickling filters and rotating biological contactor technology, advanced submerged systems (including MBBRs and IFAS) and their key role in the treatment of contaminated air, and finally to nitrogen removal employing new microbial pathways such as Anammox. This monograph emphasizes the biological aspects of the processes.

This book examines the very current issue of wood waste treatment to a solid biofuel for energy recovery. The book is dedicated to research in the densification processes of wood waste and its mathematical description for uniaxial densification into compact biofuels - briquettes. This monograph, derived from an experimental research of densification process in laboratory conditions and also in real technologies in practice, provides a thorough understanding of the influencing parameters impact during densification of wood waste into solid biofuel. The book shows the experimental strategy to determine the effects of individual parameters and specifies their impact on the resulting density of the briquettes. The publication also defines the level of importance of the results in terms of optimization of the densification machine's pressing chamber. Using a designed mathematical model, which was a result of experimental research and which can serve to predict the density of briquettes for some predefined densification conditions and can aid in the design of densification machines, the author has made this topic accessible beyond his discipline, biofuels producers and the academic community.

India is facing a river pollution crisis today. The origins of this crisis are commonly traced back to post-Independence economic development and urbanisation. This book, in contrast, shows that some important early roots of India's river pollution problem, and in particular the pollution of the Ganges, lie with British colonial policies on wastewater disposal during the late 19th and early 20th centuries. Analysing the two cornerstones of colonial river pollution history during the late 19th and early 20th centuries - the introduction of sewerage systems and the introduction of biological sewage treatment technologies in cities along the Ganges - the author examines different controversies around the proposed and actual discharge of untreated/treated sewage into the Ganges, which involved officials on different administrative levels as well as the Indian public. The analysis shows that the colonial state essentially ignored the problematic aspects of sewage disposal into rivers, which were clearly evident from European experience. Guided by colonial ideology and fiscal policy, colonial officials supported the introduction of the cheapest available sewerage technologies, which were technologies causing extensive pollution. Thus, policies on sewage disposal into the Ganges and other Indian rivers took on a definite shape around the turn of the 20th century, and acquired certain enduring features that were to exert great negative influence on the future development of river pollution in India. A well-researched study on colonial river pollution history, this book presents an innovative contribution to South Asian environmental history. It is of interest to scholars working on colonial, South Asian and environmental history, and the colonial history of public health, science and technology.

In the last ten years (2009-2019), flooding caused the death of over 48,000 people, and affected over 697 million people globally. This is expected to increase as a result of climate change, population growth and urbanisation. Floods can cause infections due to the release of water-borne pathogens from surcharged combined sewers and other sources of faecal contamination on urban surfaces such as concrete, asphalt, gravel, pavement, playground rubber tiles and grass. Using laboratory experiments with faecal indicator bacteria Escherichia coli, and with Bacillus subtilis spores, and MS2 bacteriophages under controlled exposure to simulated sunlight, this research contributes towards a better understanding of the environmental parameters that affect the concentration of pathogens in contaminated shallow water bodies and on different urban surfaces. Also, several sampling methods are assessed for the recovery of bacteria from flood-prone urban surfaces. This study suggests that given the sunlight conditions after an urban flood, the concentration of indicator organisms and of total suspended solids and the surface type it is possible to estimate the fate of selected pathogens. The observations and results presented in this study contribute to the development of policy-making tools for rapid implementation of appropriate measures to mitigate public health risks after flooding. This book: - highlights the relation of urban floods with water-borne diseases. -stresses for the first time the importance of urban surfaces (pavement, concrete, asphalt, etc.) on the inactivation of water-borne pathogens. -provides equations that can be used to develop policy-making tools for implementation of appropriate measures to mitigate public health risks after flooding.

The focus of the book is on how to use mass and heat balances to simulate and design biological wastewater treatment processes. All the main processes for biological wastewater treatment are covered viz. activated sludge processes for carbon and nitrogen removal, anaerobic digestion, sequencing batch reactors, and attached growth processes.

Giving you the first comprehensive presentation of the ground breaking research undertaken at Heriot Watt University, with Research Council and industrial funding, this book brings a new perspective to the design of building drainage and vent systems. It provides the building services community with clear and verifiable design methods that will be robust enough to meet challenges such as climate change and water conservation; population migration to the mega cities of the developing world, and the consequent pressures of user concentration; the rise of the prestige building and the introduction of new appliances and control strategies. These all combine to make traditional codified design guidance insufficient. Many assumptions in existing codes defining the entrained airflows within building drainage vent systems cannot be theoretically supported, so designers concerned with these systems need analysis and simulation capabilities which are at least as reliable as those enjoyed by other building services practitioners. The Method of Characteristics solution techniques which are well established in the pressure surge field are now used to provide solutions for drainage designers. The material is applied to a whole range of abstract scenarios then to a series of real world applications including the forensic modelling of the SARS virus spread within Amoy Gardens in 2003 and the refurbishment of the O2 Dome. Applications to specialised services, including underground station drainage and highly infectious disease treatment facilities are discussed and demonstrated, alongside the use of design and simulation techniques in support of product development. Aimed at both professional and academic users, this book serves both as a design aid and as a core text for specialist masters courses in public health and building services engineering.

A sine qua non of control system development for modern sewer networks is the preservation of the water system around a network 's outflow(s). Several approaches have been proposed for the optimisation of sewage control and Optimal Real-time Control of Sewer Networks provides a comparative synthesis of a central sewer network flow control based on two of these: nonlinear-optimal and multivariable-feedback control.

Testing and comparison of these protocols are made on the basis of their control results for the large-scale sewer network located around the river Obere Iller in Bavaria. The control strategies implemented within this network are based on this study.

From the selection of possible methods of control and moving to the implementation of those methods in a real sewer system, this monograph will be invaluable to control and civil engineers working in sewage flow and wastewater treatment and of interest to academics wishing to see how their ideas on optimal control work out when practically applied.

From Waste to Value investigates how streams of organic waste and residues can be transformed into valuable products, to foster a transition towards a sustainable and circular bioeconomy. The studies are carried out within a cross-disciplinary framework, drawing on a diverse set of theoretical approaches and defining different valorisation pathways. Organic waste streams from households and industry are becoming a valuable resource in today's economies. Substances that have long represented a cost to companies and a burden for society are now becoming an asset. Waste products, such as leftover food, forest residues and animal carcasses, can be turned into valuable products such as biomaterials, biochemicals and biopharmaceuticals. Exploiting these waste resources is challenging, however. It requires that companies develop new technologies and that public authorities introduce new regulation and governance models. This book helps policy-makers govern and regulate bio-based industries, and helps industry actors to identify and exploit new opportunities in the circular bioeconomy. Moreover, it provides important insights for all students and scholars concerned with renewable energy, sustainable development and climate change.
