Download Air Sparging for Site Remediation Book in PDF, ePub and Kindle
The problem of aquifer contamination remains one of the greatest challenges facing environmental scientists and engineers. Air sparging, a technique unknown until recently, has emerged with increasing application frequency as an alternative to both the pump-and-treat technology and conventional in situ bioremediation for treating this problem. This book, featuring contributions from the world's most experienced air sparging practitioners, conveys the latest practical experience and information from North America and Europe. Air Sparging for Site Remediation presents an overview of air sparging in general and detailed information on particular air sparging technologies and their applications. The book examines the application of the technology to a variety of contaminants, including hydrocarbons, pesticides, nitrates, and chlorinated hydrocarbons. In addition, these specific topics and more are discussed:

Download Handbook of Bioremediation (1993) Book in PDF, ePub and Kindle
Written by leading soil and ground-water remediation scientists, Handbook of Bioremediation presents information regarding the processes, application, and limitations of using remediation technologies to restore contaminated soil and ground water. It covers field-tested technologies, site characterization requirements for each remediation technology, and the costs associated with their implementation. In addition to discussions and examples of developed technologies, the book provides insights into technologies ranging from theoretical concepts to limited field-scale investigations. In situ remediation systems, air sparging and bioventing, the use of electron acceptors other than oxygen, natural bioremediation, and the introduction of organisms into the subsurface are among the specific topics covered in this invaluable handbook.

Download Analysis of Selected Enhancements for Soil Vapor Extraction Book in PDF, ePub and Kindle
This report provides an engineering analysis of, and status report on, selected enhancements for soil vapor extraction (SVE) treatment technologies. The report is intended to assist project managers considering an SVE treatment system by providing them with an up-to-date status of enhancement technologies; an evaluation of each technology's applicability to various site conditions; a presentation of cost and performance information; a list of vendors specializing in the technologies; a discussion of relative strengths and limitations of the technologies; recommendations to keep in mind when considering the enhancements; and a compilation of references. The performance of an SVE system depends on properties of both the contaminants and the soil. SVE is generally applicable to compounds with a vapor pressure of greater than 1 millimeter of mercury at 20EC and a Henry s Law constant of greater than 100 atmospheres per mole fraction. SVE is most effective at sites with relatively permeable contaminated soil and with saturated hydraulic conductivities of greater than 1 x 10 or 1 x 10 centimeter per second (cm/s). SVE by itself does not effectively remove contaminants -3 -2 in saturated soil. However, SVE can be used as an integral part of some treatment schemes that treat both groundwater and the overlying vadose zone. Enhancement technologies should be considered when contaminant or soil characteristics limit the effectiveness of SVE or when contaminants are present in saturated soil. The five enhancement technologies covered in this report are as follows and are described in the following subsections: * Air Sparging * Dual-phase Extraction * Directional Drilling * Pneumatic and Hydraulic Fracturing * Thermal Enhancement.

Download Unit Operations in Environmental Engineering Book in PDF, ePub and Kindle
This book discusses the practical aspects of environmental technology organized into eight chapters relating to unit operations as follows: 1. Biological Technology2. Chemical Technology3. Containment and Barrier Technology4. Immobilization Technology5. Membrane Technology6. Physical Technology7. Radiation and Electrical Technology8. Thermal Destruction TechnologyTraditional technologies have been included, as well as those that can be considered innovative and emerging. The traditional approaches have been the most successful, as contractors are careful about bidding on some of the newer technologies. However, as regulatory requirements increase, markets will open for the innovative and emerging processes. There will be increasing pressure to break down complex waste streams, with each subsequent stream demanding separate treatment. In addition, a number of technologies have been developed by combining processes directly, or in a treatment train, and these developments are expected to assume increasing importance. However, such concerns as uncertainties due to liability, regulatory approval, price competition, and client approval have limited the application of some of these newer technologies.
