One of the most widely used techniques for treating soils contaminated with volatile organic compounds, soil vapor extraction (SVE) can also be applied to semi-volatile organic compounds (SVOCs) if the soil is heated, by applying electromagnetic energy in the radio frequency (FR) range, to increase the vapor pressure of the contaminants. Although RF-SVE systems used in previous field demonstrations have had varying degrees of success, questions remain concerning its viability and cost-effectiveness.Soil Vapor Extraction Using Radio Frequency Heating: Resource Manual and Technology Demonstration covers detailed scientific and engineering information that answers these questions. The book includes the necessary databases, equations, and example calculations for RF heating. The theoretical and practical information included will facilitate future testing of RF-SVE treatment of soils. Additionally, the book provides information for a full-scale engineering design of potential RF-SVE applications. The authors use this information to examine predicted performance, magnitude of costs, and modifications to the design that may decrease cost. Soil Vapor Extraction Using Radio Frequency Heating: Resource Manual and Technology Demonstration gives an economic analysis of this innovative technology and considers other possible applications for it.Features

The number of worldwide solid waste landfills and abandoned dumps is growing steadily in both industrialized and developing nations. The key to successful waste containment is often a final cover for placement over the landfill or dump. This book presents the essential elements for the design of final covers which are environmentally safe and secure. With an overview of regulations in the United States and Germany provided, the authors emphasize performance-based design for site specific conditions. Individual components of candidate cover systems are examined, including surface, protection, drainage, barrier, gas collection, and foundation layers for the entire range of natural soil materials and geosynthetics.
