Download or read book Stream Ecology and Self Purification written by Frank R. Spellman and published by CRC Press. This book was released on 1996-07-01 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the Preface This text is designed to provide a fundamental knowledge of the phenomenon known as self-purification in streams. Sufficient background information and references on stream ecology and self-purification are presented to provide readers with an understanding of the various concepts under discussion. Moreover, along with the stream self-purification process and biological indication of stream health, water quality and source sampling are discussed in depth. Wastewater and water treatment personnel, students, specialists, water resource managers, ecologists, regulators, and water pollution control personnel concerned with activities and preventive measures to prevent stream pollution will find this consolidated information important. Other professional wastewater- and water-related staff from governmental agencies, municipal water supply and wastewater systems, public health departments, and environmental health agencies will also find the information valuable. This text, however, is also intended for readers and groups interested in and concerned with stream pollution and stream contamination control. This text can be used as a basic or supplemental text in undergraduate and technical school courses in aquatic ecology or stream quality enhancement and protection. It can also be consulted as an environmental reference text by school, municipal, and water resource professionals.

Download or read book Stream Ecology and Self Purification written by Frank R. Spellman and published by CRC Press. This book was released on 2001-06-05 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new edition of a very successful standard reference is expanded and fully reworked. The book explains and quantifies the processes whereby streams cleanse themselves, reducing their pollutant load as a natural process. Mechanisms of purification in running waters have always been critical with regard to clearly identified pollution sources. This new edition explains the self-purifying function of streams and rivers in light of recent EPA rules on nonpoint pollutants and total maximum daily loads (TMDLs). It also covers basic concepts such as biological oxygen demand (BOD). Also new in this edition is an extended discussion of how streams originate and how they fit into the geomorphology of the earth and other water supply sources. Information is presented on aquatic life, including macroinvertebrates and their role as bioindicators of stream health. Chapter review tests and answers are included so that the readers can evaluate their mastery of the concepts presented. Stream Ecology and Self-Purification: An Introduction, 2nd Edition serves as a practical introduction to ecology combined with an explanation of how streams absorb and react to pollution. This text will prove valuable to water and wastewater plant operators, watershed managers, trainers, environmental students, water quality professionals, and will be an excellent preparation aid to wastewater/water operator licensing exams.

Download or read book Chapter III Self Purification of Streams written by and published by . This book was released on 1960 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water is the most plentiful liquid on earth. It is a requirement for all life, whether it is used in metabolic processes, as a solvent of minerals, or in the disposal of waste. Indeed, it is difficult to name a natural phenomenon in which water, in one form or another, has not had a role. Nature has provided for the conservation of this abundant and valuable liquid by endowing it with a considerable capacity to rid itself of foreign substances. This process, known as self-purification, is an inherent property of water. The water may be moving in streams or be relatively static as in lakes and ponds, but the natural processes of purification are similar. Advantage is taken of this intrinsic ability of water to purify itself by using it as a final stage in the treatment of sewage and industrial wastes. Streams polluted by domestic wastes (those derived from human populations) or industrial wastes (the liquid wastes of wet-process industries and acid mine drainage) may be rendered stable by self-purification. In most instances, such polluted water becomes relatively innocuous biologically and again serves nature in one role or another. This purification is accomplished by a combination of physical, chemical, and biological forces. The extent to which each force operates is dependent upon the type of contamination. Physical forces dispose of suspended solids; chemical forces cause reactions which render unstable wastes innoxious; and biological forces contribute to the stability of the stream by enhancing both physical and chemical phenomena. The biological forces are the most active, and the most important, in the equilibration of a stream.

Available in PDF, EPUB and Kindle. Book excerpt: Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

Download or read book Simplified Techniques for Determination of Theoretical and Effective Self purification Coefficients of Polluted Streams written by Cecil Hale J. Hull and published by . This book was released on 1960 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A simplified technique is proposed for determining the self-purification coefficient in surface streams. A formula for f is derived from the basic Streeter-Phelps (1925) oxygen-sag equation. The technique proposed for use of this formula appears to offer many possibilities for studying the oxygen balance of water in both laboratory and field investigations. The value of the technique is in its simplicity. It requires only three measurements: temperature, dissolved oxygen, and BOD. The need to determine k1, k2, or time-of-flow is eliminated."--Abstract.
