Book Description
Disposal of organic sludge and liquid agricultural wastes is a universal problem. Their production cannot be halted and as steps are taken to maintain or improve the quality of rivers and lakes it grows in quanti ty. The Commission's early awareness of the need for action to prepare for substantial growth in the Community's' sludge disposal problem led to the setting up of the COST 68 project to coordinate and guide European research and development work with particular emphasis on recycling sludge to agricultural land. Two years ago the field of research activi ties was extended to liquid agricultural wastes. This Symposium is the latest opportunity to provide a comprehensive review of the results of the project, to define current trends in practice and to establish by discussion the priorities for research over the next few years. The development of instrumentation and of analytical techniques during the period has extended our knowledge of the organic and inorganic constituents of sewage sludge and agricultural wastes and enabled us more readily to identify and measure the risks to which our general environment may be exposed when disposing of it. This evolution of understanding is a continuing process and an essential guide to the modification of disposal practices to achieve safer and more efficient operations. However, it is important to take a broad view of the application of research findings in the light of the considerable contrast in conditions in different parts of the world.

Book Description
Enactment of the Federal Water Pollution Control Act Amendments of 1972 fostered interest in land application of treated municipal wastewater and sludge. Most application systems are designed for use in both cropland and forest land. While considerable information is available on application of wastewater and sludge to cropland, there has been a general lack of information concerning the effects of such applications to forest land. Although surface mining is the most economical method for removing mineral resources, its detrimental impacts on the land surface, landscape, and ecological environment have caused growing concern among public interest groups and government agencies. Given the current energy crisis and increasing scarcity of mineral resources, the problem of reclaiming lands disturbed by surface mining will grow in importance. New reclamation regulations, together with the rising cost of commercial fertilizer, have resulted in an upsurge of interest in the use of municipal wastewater and sludge as fertilizer substitutes and soil amendments to facilitate vegetative rehabilitation of drastically disturbed lands. The symposium reported in this book was concerned with application of current knowledge on economic and environmental feasibility of treating forest land with municipal sewage effluent and sludge, as well as rehabilitation of land disturbed by surface mining. Interest in this topic was generated by members of the Water Quality Working Group of the Pinchot Institute's Consortium for Environmental Forestry Studies. The symposium was attended by more than 300 participants from 35 states. It was a continuing education service of The Pennsylvania State University's School of Forest Resources, College of Agriculture and Institute for Research on Land and Water Resources, in cooperation with the Surface Environment and Mining (SEAM) Program, Forest Service, U.S. Department of Agriculture; the Office of Water Research and Technology, U.S. Department of the Interior; and the U.S. Environmental Protection Agency.

Book Description
FROM THE PREFACE This textbook explains and discusses many of the unit operations used for processing municipal sewage sludge. It also contains valuable information on the available methods for final disposition of this sludge. This textbook can be used for planning, designing, and implementing municipal sewage sludge management projects.
