Over the last 30 years, pollution and its effects on the environment have emerged as leading topics of interest. The desire for positive action to restore and protect the environment is growing worldwide. How serious are particular types of pollution? Is technology currently available to abate pollution? And do the costs of abatement justify the degree of abatement achieved? In the series, Handbook of Environmental Engineering, these questions are answered for the three basic forms of pollution and waste: gas, solid and liquid. Volume 7 in the series, Biosolids Engineering and Management, is a collection of methods of practical design, calculation and numerical examples that illustrate how organized, analytical reasoning can lead to the discovery of clear, direct solutions, especially in the areas of biosolids management, treatment, disposal and beneficial use. The book s distinguished panel of authors provides insight into a range of topics, including sludge and biosolids transport, pumping and storage, sludge conversion to biosolids, chlorination, stabilization, regulatory requirements, costs, agricultural land application, landfill, ocean disposal, combustion, incineration and sludge treatment process selection. Along with its sister book - Volume 6, Biosolids Treatment Processes Volume 7 is designed to be a basic biosolids treatment textbook, as well as a comprehensive reference book for advanced undergraduate and graduate students, designers of waste treatment systems, scientists and researchers. Both insightful and illuminating, Volume 7, Biosolids Engineering and Management gives state-of-the-art illustrations of the theory and practice of individual biosolids management systems and pertinent information on physical, chemical and biological treatment technologies used today.
Preface
The past thirty years have seen a growing desire worldwide that positive
actions be taken to restore and protect the environment from the degrading
effects of all forms of pollution—air, water, soil, and noise. Since pollution is
a direct or indirect consequence of waste, the seemingly idealistic demand for
“zero discharge” can be construed as an unrealistic demand for zero waste.
However, as long as waste continues to exist, we can only attempt to abate
the subsequent pollution by converting it to a less noxious form. Three major
questions usually arise when a particular type of pollution has been identified:
(1)Howserious is the pollution? (2) Is the technology to abate it available? (3) Do
the costs of abatement justify the degree of abatement achieved? This book is one
of the volumes of the Handbook of Environmental Engineering series. The principal
intention of this series is to Giúp readers formulate answers to the above three
questions.
The traditional approach of applying tried-and-true solutions to specific pol-
lution problems has been a major contributor to the success of environmen-
tal engineering and has accounted in large measure for the establishment of
a “methodology of pollution control.” However, the realization of the ever-
increasing complexity and interrelated nature of current environmental prob-
lems renders it imperative that intelligent planning of pollution abatement
systems be undertaken. Prerequisite to such planning is an understanding of
the performance, potential, and limitations of the various methods of pollution
abatement available for environmental scientists and engineers. This series of
handbooks reviews at a tutorial level a broad spectrum of engineering systems
(processes, operations, and methods) currently being utilized, or of potential
utility, for pollution abatement. We believe that the unified interdisciplinary
approach presented in these handbooks is a logical step in the evolution of
environmental engineering.
Discussion of the various engineering systems presented shows how an
engineering formulation of the subject flows naturally from the fundamental
principles and theories of chemistry, microbiology, physics, and mathematics.
This emphasis on fundamental science recognizes that engineering practice
has in recent years become more firmly based on scientific principles rather
than on its earlier dependency on empirical accumulation of facts. It is not
intended, though, to neglect empiricism where such data lead quickly to the
most economic design; certain engineering systems are not readily amenable to
fundamental scientific analysis, and in these instances we have resorted to less
science in favor of more art and empiricism.
Since an environmental engineer must understand science within the context
of application, we first present the development of the scientific basis of a
particular subject, followed by exposition of the pertinent design concepts and
operations, and detailed explanations of their applications to environmental
quality control or remediation. Throughout the series, methods of practical
design and calculation are illustrated by numerical examples. These examples
clearly demonstrate howorganized, analytical reasoning leads to themost direct
and clear solutions.Wherever possible, pertinent cost data have been provided.
Our treatment of pollution-abatement engineering is offered in the belief that
the trained engineer should more firmly understand fundamental principles, be
more aware of the similarities and differences among many of the engineering
systems, and exhibit greater flexibility and originality in the definition and
innovative solution of environmental pollution problems. In short, the environ-
mental engineer should by conviction and practice be more readily adaptable to
change and progress.
Coverage of the unusually broad field of environmental engineering has
demanded an expertise that could only be provided through multiple authors.
The authors use their customary personal style in organizing and presenting
their topics; consequently, the topics are not discussed in a homogeneous man-
ner. Moreover, owing to limitations of space, some of the authors’ topics could
not be discussed in great detail, andmany less important topics had to bemerely
mentioned or commented on briefly. All authors have provided an excellent list
of references at the end of each chapter for the benefit of the interested readers.
As each chapter is meant to be self-contained, some mild repetition among
the various texts was unavoidable. In each case, all omissions or repetitions
are the responsibility of the editors and not the individual authors. With the
current trend toward metrication, the question of using a consistent system of
units has been a problem. Wherever possible, the authors have used the British
system (fps) along with the metric equivalent (mks, cgs, or SIU) or vice versa.
Conversion factors for environmental engineers are attached as an appendix in
this handbook for the convenience of international readers. The editors sincerely
hope that this duplication of units will prove to be useful to the reader.
The goals of the Handbook of Environmental Engineering series are (1) to cover
entire environmental fields, including air and noise pollution control, solid
waste processing and resource recovery, physicochemical treatment processes,
biological treatment processes, biosolids management, water resources, natural
control processes, radioactivewaste disposal, and thermal pollution control; and
(2) to employ a multimedia approach to environmental pollution control since
air, water, soil, and energy are all interrelated.
As can be seen from the above handbook coverage, no consideration is given
to pollution by type of industry, or to the abatement of specific pollutants.
Rather, the organization of the handbook series has been based on the three
basic forms in which pollutants and waste are manifested: gas, solid, and liquid.
In addition, noise pollution control is included in the handbook series.
This book, volume 7, Biosolids Engineering and Management, is a sister book to
volume 6, Biosolids Treatment Processes. Both biosolids books have been designed
to serve as basic biosolids treatment textbooks as well as comprehensive ref-
erence books. We hope and expect they will prove of equally high value to
advanced undergraduate and graduate students, to designers of wastewater,
biosolids, and sludge treatment systems, and to scientists and researchers. The
editors welcome comments from readers in all of these categories. It is our hope
that both books will not only provide information on the physical, chemical, and
biological treatment technologies, but also serve as a basis for advanced study
or specialized investigation of the theory and practice of individual biosolids
management systems.
This book (Volume 7) covers the topics of sludge and biosolids transport,
pumping and storage, sludge conversion to biosolids, waste chlorination for
stabilization, regulatory requirements, cost estimation, beneficial utilization,
agricultural land application, biosolids landfill engineering, ocean disposal
technology assessment, combustion and incineration, and process selection for
biosolids management systems. The sister book (Volume 6) covers topics on
biosolids characteristics and quantity, gravity thickening, flotation thickening,
centrifugation, anaerobic digestion, aerobic digestion, lime stabilization, low-
temperature thermal processes, high-temperature thermal processes, chemical
conditioning, stabilization, elutriation, polymer conditioning, drying, belt filter,
composting, vertical shaft digestion, flotation, biofiltration, pressurized ozona-
tion, evaporation, pressure filtration, vacuum filtration, anaerobic lagoons, ver-
micomposting, irradiation, and land application.
The editors are pleased to acknowledge the encouragement and support
received from their colleagues and the publisher during the conceptual stages
of this endeavor. We wish to thank the contributing authors for their time and
effort, and for having patiently borne our reviews and numerous queries and
comments.We are very grateful to our respective families for their patience and
understanding during some rather trying times.
