  • Basic Water and Wastewater Treatment

    Butterworths Basic Series
    • 1 Edición
    • T H Y Tebbutt
    • Inglés
    Basic Water and Wastewater Treatment discusses the water cycle, flow measurement, physical treatment processes, chemical treatment processes, biological treatment process, and sludge handling and treatment. The book also describes the use of the BASIC computer program to calculate problems involving water pollutants. Flow measurements involve the use of a gauging structure, velocity measurements of a known cross-section, or dilution gauging. To evaluate, in quantitative terms, the effects of a certain pollutant discharged and received by a body of water, the investigator can employ a tool in chemical dilution gauging—the mass balance analysis. Many microorganisms, organic and inorganic compounds degrade in a natural process of self-purification; their decay can be modeled as an exponential function. One standard of water treatment facility or wastewater treatment plant cannot be built to deal with all the various components of water pollution. The book cites relevant standards such as the EC Directive 80/778/EEC: "Quality of Water Intended for Human Consumption" in the EU; the "Safe Drinking Water Act" in the U.S.A.; and the "Guidelines for Drinking Water Quality" issued by the World Health Organization. The book describes water quality parameters, water supply sources, and wastewater collection, including its treatment and disposal.

  • Ecology of the Northern Lowland Bogs and Conifer Forests

    • 1 Edición
    • James A. Larsen
    • Inglés
    Ecology of the Northern Lowland Bogs and Conifer Forests is a book on the ecology of bogs and conifer swamps and, to some extent, the marshlands. The chapters that follow are, for the most part, a review of what is known about the northern bogs and lowland forests, written in the terminology of science in the hope, as well as the expectation, that such knowledge will be of value to those who appreciate the beauty of bogs and marshlands, to ecologists and other biological scientists, naturalists, wildlife conservationists, hunters, trappers, construction engineers, as well as to others whose vocations or avocations take them afield. The discussion is devoted, at least primarily, to the ecology of one kind of wetland—the lowland bogs and conifer forests—and treats only in passing the marshlands and other kinds of vegetational communities that are also classified as wetlands. Of particular concern are the lowland peat bogs and forests, especially those that have developed to a point where their identity is indisputable for the simple reason that no other review of accumulated knowledge on these vegetational communities is presently available.

    Environmental Implications of Expanded Coal Utilization focuses on the increasing consideration of coal as an alternative source of energy. This book comes as an answer to the issues on health and environment regarding the extraction, production, and use of coal. Composed of nine chapters, the selection starts by underlining the potential prospects for coal, which plays a vital role in meeting energy demands. The book also shows that problems have evolved regarding the use of coal, including land disturbance and increased land occupation due to mining. The text also notes that the international trade of coal will surely generate waste products, and some of which can be the result of poor transportation and handling. The book focuses on coal gasification and liquefaction and emphasizes that the processes involved must be carefully understood in order to avoid the environmental impacts of coal use. Attempts have been made to establish a conceptual framework to be used in assessing the health and environmental health impacts of the conversion and utilization of coal. Relative to this, discussions that follow include the trace elements that are the products of coal combustion and conversion and also coal derived carbon compounds. Another sector is focused on the evaluation of the effects of emissions on human health, especially of workers in the industry. The effects of the utilization of coal on communities are also considered. The text is a vital source of information to those involved in the research on the use of coal as alternative source of energy.

  • Key Environments: Malaysia

    • 1 Edición
    • Earl of Cranbrook
    • Inglés
    Of the vast area of structurally similar vegetation that forms the Far Eastern tropical rain forest block, only the forests of peninsular Malaysia lie on the mainland of Asia. Although showing some influence from this source, the flora and fauna are distinctive and exceedingly rich in species. Among other factors, this richness reflects the complex structure of the vegetation, justly famous for the extensive stands of tall trees that create the conditions to which many smaller plants, fungi and a huge variety of animals are adapted. After a century of scientific investigation, it is now possible to understand peninsular Malaysia's complex ecosystem as an essential prerequisite to the successful management for conservation and long-term productivity in the area. Compiled by authors with personal experience of the region, this book constitutes the most authoritative account of this diverse and fragile region. It is essential reading for all those interested in Malaysia and its conservation.

  • Fish and River Pollution

    • 1 Edición
    • J. R. Erichsen Jones
    • Inglés
    Fish and River Pollution deals with experimental and field research connected with the effects of pollution in fish, and the useful data gathered from these studies. After reviewing some experiments made on the effects of pollution on fish, the author discusses pollution by oxygen-reducing effluents such as sewage, milk washing, and other solutions that can be broken down by microorganisms, a process that uses up dissolved oxygen in the water. The experiments conducted by Shelford and Allee, which the author cites, studies the reactions of fish to different concentrations of atmospheric gases, particularly as fish detect low concentrations of oxygen more sensitively than man. The paper also discusses the time-effect relationship of a toxic substance to fish as immersion time, time needed for advancement, minimum time of exposure, and immersion time to fatality. The effect of thermal pollution such as that generated in thermal plants to produce electricity, though chemically toxic-free, can significantly change the temperature of the water where fish live. Such temperature change can affect water viscosity, rate of water oxygen absorption, development of sewage fungus, and changes in natural invertebrate fauna. This book can be appreciated by environmentalists, aquatic researchers, zoologists, and marine biologists.

  • Methods of Treatment of Unstable Ground

    • 1 Edición
    • F G Bell
    • Inglés
    Methods of Treatment of Unstable Ground focuses on the methods of treatment that have been adopted by engineers in their attempts to make unstable ground usable. These methods are meant to stabilize ground, either temporarily as in ground-water lowering or freezing techniques, or permanently as in grouting. This book is comprised of 11 chapters. The first of which reviews some of the modern techniques in addressing problems caused by unstable ground, including those caused by water in excavations, instability of natural or excavated slopes, the settlement of structures on soft or loose soils, and subsidence due to extraction of minerals from the ground. These techniques range from ground-water lowering to the use of an impermeable barrier around the excavation to prevent inflow and at the same time maintain the surrounding water table at its normal level. Attention then turns to the use of electro-osmosis and electrochemical stabilization in ground engineering; control of groundwater by excluding it through grouting; and fundamental conditions governing the penetration of grouts. The remaining chapters explore grout selection based on engineering performance; ground conditions in mining areas; clay grouting and alluvial grouting; and ground freezing. Finally, the use of cement to stabilize soil and of vibroflotation to improve poor ground below foundations of structures is described. This book should prove useful to engineers engaged in ground engineering.

    Biometeorological Methods provides a unified look at methodologies in biometeorology. Examples of biometeorological studies have been chosen not because the results are necessarily significant but because the method is instructive. The book begins with a brief survey of biometeorology to orient the reader approaching the subject for the first time. The remaining chapters seek to place in perspective the various experimental, empirical, analytical, and physical methods that are being used or could be used in biometeorology. Key topics discussed include space and time considerations in the sampling of the atmosphere; the design of biometeorological experiments; the use of tables, graphs, and charts in the search for biometeorological relationships; statistical and physical methods; and the synoptic approach. Also covered are studies on seasonal relationships, past climates, and climatic classification and indices. The present volume should be of value to anyone seeking assistance in the design of experiments and analysis of environmental data.

    Heavy Metals in the Aquatic Environment contains the proceedings of an international conference held in Nashville, Tennessee in December 1973. This conference is co-sponsored by the International Association on Water Pollution Research, the Sport Fishing Institute, the American Fishing Tackle Manufacturers Association, and Vanderbilt University's Department of Environmental and Water Resources Engineering. Contributors focus on the hazards posed by heavy metals present in the aquatic environment and how to control them. This text consists of 45 chapters divided into eight sections. This book assesses the environmental impact of heavy metals found in the aquatic environment; the economic impact of removing them from waste effluents; and the costs vs. benefits attained by their removal. The social costs are also evaluated. After an introduction to dose-response relationships resulting from human exposure to methylmercury compounds, the discussion turns to the toxicity of cadmium in relation to itai-itai disease; the effects of heavy metals on fish and aquatic organisms; and the analytical methods used for measuring concentrations of methylmercury and other heavy metals. The next sections explore the transport, distribution, and removal of heavy metals, along with regulations, standards, surveillance, and monitoring aimed at addressing the problem. This book will be of interest to planners and policymakers involved in water pollution control.

    Underwater Scattering and Radiation describes the relevant theoretical foundations of underwater scattering and radiation. Acoustic scattering from elastic solids is discussed, and variational formulations in acoustic radiation and scattering are presented. Surface waves and quasi-cylindrical modes are also explored, along with the Helmholtz-Kirchhoff integral corollaries. Comprised of two chapters, this volume begins with a comprehensive account of scattering by elastic objects, focusing on the classic idealized shapes of spheres and infinite cylinders. The reader is introduced to important concepts such as normal modes, the S-matrix, and the T-matrix as well as resonances, whispering gallery modes, Franz modes, and Stoneley waves. Subsequent sections describe methods for treating scattering by elastic bodies of more general shapes. The T-matrix formalism is discussed and then applied to spheroidal scatterers and finite cylinders. The second chapter analyzes how variational principles can be used in acoustics, with the choice of topics directed toward applications to underwater acoustic radiation and scattering. This book will be of interest to physicists.
