This book addresses a complex issue - water sustainability - that requires a combined approach to manage both water and energy. It highlights several technologies that have been introduced to study the water-energy linkage. It also discusses the need to develop effective laws for water management. In turn, the book assesses hybrid biological systems and demonstrates why they are better for the wastewater treatment process. Lastly, it reviews wastewater quality requirements, which have been the primary driver of industrial wastewater treatment programs in India. Gathering selected, high-quality research papers presented at the IconSWM 2018 conference, the book offers a valuable asset, not only for researchers and academics, but also for industrial practitioners and policymakers.
This volume presents a critical analysis and timely synthesis of the past decade of intensive research, development, and demonstrations on the in situ bioremediation of perchlorate in groundwater. The intended audiences include the decision makers, practicing engineers and hydrogeologists who will select, design, and operate these remedial systems, as well as researchers seeking to improve the current state-of-the-art. Our hope is that this volume will serve as a useful resource to assist remediation professionals in applying and developing the technology as effectively as possible. An overview of the current state-of-understanding of perchlorate remediation is followed by a discussion of basic principles of microbial and abiotic processes, and of the engineering and implementation issues underlying the technologies described. Characterization of both anthropogenic and natural sources of perchlorate, including isotopic analysis to distinguish between differing sources, precedes discussions of the advantages, performance, and relative costs of applying a range of remedial technologies. Active, semi-passive, and passive in situ bioremediation are fully described and compared with emphasis on field application. Cost information for each technology, using case studies and analyses of several template sites, covers capital costs, as well as costs for laboratory testing, pilot-scale demonstration, design, system operation, monitoring and maintenance during operations, and demolition and restoration after remediation. In addition, analogous cost data are presented for pump-and-treat systems for each template site to illustrate the potential cost savings associated with the use of alternative approaches. Emerging technologies such as monitored natural attenuation, phytoremediation, and vadose zone bioremediation are described, and field demonstrations are used to illustrate the current stage of maturity and the potential applicability of these approaches for specific situations. Each chapter in this volume has been thoroughly reviewed for technical content by one or more experts in each subject area covered.
Hands-On Maintenance for Water/Wastewater Equipment deals with equipment maintenance as individual components, not as complete machines. This allows more information about the design, application and maintenance requirements of machinery to be presented. The text covers basic operating characteristics of machinery components, making it a valuable reference source as well as a training and maintenance manual. Written in easy-to-understand language, without complex formulas or technical theories, this text provides you with basic information to help you acquire a general understanding of how components function and how to keep equipment operating properly.
Solid Waste Landfilling: Concepts, Processes, Technology provides information on technologies that promote stabilization and minimize environmental impacts in landfills. As the main challenges in waste management are the reduction and proper treatment of waste and the appropriate use of waste streams, the book satisfies the needs of a modern landfill, covering waste pre-treatment, in situ treatment, long-term behavior, closure, aftercare, environmental impact and sustainability. It is written for practitioners who need specific information on landfill construction and operation, but is also ideal for those concerned about the possible return of these sites to landscapes and their subsequent uses for future generations.
This Volume presents applications of hydrocarbon microbiology in the context of environmental pollutant degradation, covering pollutants such as petroleum and related wastes (i.e. oil sludge), biofuels, lipid-rich wastes, chlorinated solvents and BTEX, in several environments (marine, soil, groundwater). The approaches presented range from laboratory experiments and treatment in reactors to field applications. Two chapters highlight innovative approaches to address relevant questions in pollutant degradation, such as low environmental concentrations of pollutants, and the biodegradation of complex pollutant mixtures using biofilms. Rather than presenting the applications in the form of protocols, some of the chapters in this Volume include detailed practical information on the opportunities offered by and limitations of the different approaches, providing valuable information for researchers planning to perform bioremediation experiments. 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.
Sediment transport, two-phase flow and loose boundary hydraulics
are some of the problems of interaction between fluid flow (water
or air) and boundaries that may be non-cohesive (alluvial) or
cohesive. Unlike in classical hydraulics, these boundaries can
change their shape and texture with changing flow conditions. Some
of the material from the boundaries may be entrained into the flow,
or sediment may be added to the flow, sometimes by tributaries as
suspended matter. One instance is the transport of granular
material in pipelines Since the changing boundaries are the central
feature of most flow processes in nature, the term loose boundary
hydraulics is here introduced.
This text covers the proceedings of the third International Symposium - TISAR 98, held in Amsterdam. Topics include: basin recharge; water management in arid regions; behaviour of pollutants; bank, basin, well and other types of recharge; and storage and recovery efficiency.
Every spring, the University of Massachusetts - Amherst welcomes all ''Soils Conference" Scientific Advisory Board members with open arms as we begin the planning process responsible for bringing you quality conferences year after year. With this "homecoming" of sorts comes the promise of reaching across the table and interacting with a wide spectrum of stakeholders, each of them bringing their unique perspective in support of a successful Conference in the fall. This year marks the 20 DEGREES DEGREES anniversary of what started as a couple of thoughtful scientists interested in developing partnerships that together could fuel the environmental cleanup dialogue. Since the passage of the Superfund Law, regulators, academia and industry have come to realize that models that depend exclusively on ''command and control" mandates as the operative underpinning limit our collective ability to bring hazardous waste sites to productive re-use. It is with this concern in mind that the Massachusetts Department of Environmental Protection privatized its cleanup program in 1993, spurring the close-out of over 20,000 sites and spills across the Commonwealth to date, in a manner that is both protective of human health and the environment while also flexible and responsive to varied site uses and redevelopment goals. So we gather together again, this year, to hear our collective stories and share success and challenges just as we share stories at a family gathering. Take a read through the stories contained in these proceedings.
FROM THE PREFACE Wastewater collection systems are dynamic, not static. There is no single maintenance method, equipment, or technique that works best. Keeping an open mind, trying new techniques and technologies benefits sewer system operators. No two collection systems are alike. Maintenance staffing, skill levels, equipment, budgets, age and complexity of the system make each agency unique. However, collection systems do have many traits and problems in common. Based on inventory and analysis, problems are identified. Defects may then be prioritized, and corrective maintenance operations put into effect. Preventive maintenance techniques can be applied to all collection systems. Preventive maintenance is cost-effective; it strives to prevent problems from occurring rather than reacting to difficult situations and "putting out fires." This book examines problems shared by all agencies: roots, grease, deterioration, hydraulic inefficiencies and structural defects. New solutions to age-old problems are applied: TV inspection and video interpretation, rehabilitation analysis and trenchless technologies. Computerized maintenance management and GIS softwares are discussed. Jetting, line cleaning and exciting developments in nozzle technology are included. Roots and chemical root control foam, wastewater control and grease are major topics as well. Wastewater Collection System Maintenance shares insights drawn from operator experience, trial and error, successes and failures in the field, interviews and years of research and studies. A user-friendly rating and evaluation system is explained and applied to field conditions. Equipment operation and maintenance, and "tricks of the trade" are also discussed. As cities grow, new systems are extended upstream from older sewers. Many of these core drainage basins are now under capacity and in need of capital improvement projects. There are approximately 600,000 miles of sanitary sewers in the country. Nationwide, there exists a huge backlog of sewer pipes that need rehabilitation. Replacement would cost many billions of dollars. Maintenance operators are entrusted with the care and feeding of an aging sewer infrastructure.
High quality fresh water is limited in quantity and there is a need for comprehensive water management involving representatives of all those who use water. Effective management must ensure that the best use is made of available supplies, including protection from pollution, and to limit conflicts over access to fresh water. This calls for the establishment of clearly defined policies and strategies as well as for the development of enforceable mechanisms and tools for water pollution control.

FROM THE PREFACE
This text provides an account of the nature and applications of the Coliform Index. Since the beginning of the 20th century, indicator organisms, in particular the coliform group, have been used to ensure the microbial quality of drinking water. World-wide legislation to protect consumers is based on these out-dated and unreliable tests and while there is considerable concern among scientists over their use, the water industry and regulators continue to place near total reliance on the Coliform Index. This has serious implications for public health and necessitates the debate which this book enters.
Landfilling of waste is an international issues of environmental and political concern and should be viewed as part of an integrated waste management system.

Proceedings of the Symposium on Biotechnological Advances in Processing Municipal Wastes for Fuels and Chemicals held in Minneapolis, Minn., on Aug. 15-17, 1984, and sponsored by the U.S. Department of Energy's Division of Energy from Municipal Waste and by Argonne National Laboratory's Energy and Environmental Systems Division (Energy from Municipal Waste Program)
This book explores state-of-art techniques based on methodological and modeling aspects of solid and hazardous waste management, specifically focusing on the recent trends in data acquisition and robust modeling of the results obtained. In addition to an in-depth description of the recent regulatory paradigm for solid waste disposal and revealing insights into solid waste management models, the book also addresses significant case history and remediation methodologies for sustainable development in emerging economies like India, China and Brazil. The main emphasis is on a suitable regulatory framework with site-specific baseline calibration and aimed at the robust modeling of contaminant transport and its remediation. This is based on instructive case history in various locations/regions worldwide. The focus on recent modeling and quantification methods is the backbone of the book. One of the major aspects discussed is the application of non-invasive methods for studies related to the Earth's interior, which are increasingly preferred over invasive techniques thanks to their economic utility, as well as robust techniques for the interpretation of geophysical data. The increasing demand for groundwater and energy resources, especially for rapidly emerging countries with large populations like India and China, has made it vital to derive safe utilization approaches for our resources, including suitable waste disposal and remediation methodologies that can be adopted for 'contaminated sites.'
This updated second edition summarizes screening equipment options available for industrial and municipal water and wastewater treatment. It provides a consolidated source of basic design and application to assist engineers in selecting a screen best suited for the particular application. |
