Book Synopsis Surfactants and Cosolvents for NAPL Remediation Handbook of Technology Practices by: Donald F. Lowe
Download or read Surfactants and Cosolvents for NAPL Remediation A Technology Practices Manual written by Donald F. Lowe and published by CRC Press. This book was published on 1999-03-26 with a total of 444 pages. Available in PDF, EPUB and Kindle. Book Excerpt: A $19.3 million Department of Defense grant to Rice University funds the Advanced Applied Technology Demonstration Center (AATDF). One of the goals of the project is to develop strategies to reduce non-aqueous phase liquids (NAPL) in the subsurface. Surfactants and Cosolvents for NAPL Remediation records the results of AATDF research. The manual is a guide to the practical application of surfactants/cosolvents for in situ remediation. It is intended for decision makers and anyone involved in the design or implementation of these technologies. The book discusses the situational viability of surfactants/cosolvents, possible outcomes, design and operation. Includes case studies, step-by-step instructions, and project costing worksheets. AATDF's successful research results, such as the documented surfactants and cosolvents for NAPL remediation, are an invaluable contribution to the future of subsurface remediation. Without reducing the source NAPL, the alternative is decades of plume management through pump and treat.

This complete design and operation manual gives you the tools you need to complete successful, cost-effective rehabilitation projects. The main attributes of this system, the Experimental Controlled Release System (ECRS), that distinguish it from previous test facilities include the following: Portable - can be shipped to the researcher's site or remediation site Tightly closed - facilitates mass balance Large pilot plant - a step below full-scale demonstration size Flexible test conditions - vadose zone or aquifer, chemical discharge or contaminated soil, air spray or ALL Easy to manufacture - developed design drawings, standard equipment Easy to operate and maintain - easy access, standard equipment Affordable - easy to ship and install, reduced regulatory requirements, minimal maintenance Faster tests - reduced or eliminated permitting, operate within one week of arrival, can be programmed for 24 hours This monograph presents the key information needed to design, build and operate similar modular remediation test systems or utilize two existing modular ECRS facility. The well-sealed, overhead modular design of the system reduces leakage to the environment, facilitates mass balances and controls test conditions. This allows multiple uses with minimal permissions. Modular Remediation Testing Systems is a comprehensive reference for environmental engineering researchers and engineering consultants and regulators looking for a pilot system. These pilot systems are uniquely suited to both research development and real-world application at remediation sites.

Synopsis of the book Phytoremediation of soil contaminated with hydrocarbons by Stephanie Fiorenza
Download or read the book Phytoremediation of Hydrocarbon-Contaminated Soils written by Stephanie Fiorenza and published by CRC Press. This book was published on 18.12.2020. with a total of 217 pages. Available in PDF, EPUB and Kindle. Excerpt from the book: Interest in phytoremediation as a solution to contaminants in groundwater and soil has exploded. The project documented in Phytoremediation of Hydrocarbon Contaminated Soils presents an innovative technology for environmental cleanup using in situ treatment. Describes the results of a field study focused on hydrocarbon contamination, particularly polynuclear aromatic hydrocarbons, in surface and near-surface soils. Soils contaminated with old diesel fuels were used in the field demonstration. A randomized block design allowed the researchers to test for a statistical difference in the effects of different vegetated and non-vegetated treatments. They examined the degradation of diesel components and polynuclear aromatic hydrocarbons in plots containing three different vegetation treatments, two grasses and one legume, and a no-vegetation control. The first part of the monograph provides a complete and exhaustive presentation of the results of the field research. The second part covers the design and potential costs of implementing a full-scale demonstration system, as well as the performance and potential application of the new technology. Phytoremediation of soil contaminated with hydrocarbons provides quantitative results on the use of vegetation in soil remediation. The information given about the niches and limitations of the technologies enables a more informed choice of remedial solutions for environmental cleaning.

This book was published on August 16, 2019 with a total of 185 pages. Available in PDF, EPUB and Kindle. Excerpt from the book: While it is necessary to develop innovative technologies in remediation, it is also necessary to develop innovative methods of site assessment. This monograph describes the development, testing, and performance of a new laser-induced fluorescent soil probe. A site characterization verification tool, this probe has the potential to provide a cost-effective, rapid assessment of contaminated sites. The Cone Penetrometer testing equipment moves a probe underground. The probe identifies hydrocarbon classes using a multichannel excitation and emission matrix. This technique facilitates the collection of significant amounts of subsurface information - surpassing conventional data collection methods - that can be used to quickly identify problem areas beneath a site. The technology has significant applications for: Rapid on-site environmental assessment Monitoring of remediation programs Monitoring of industrial wastewater production processes and operations Monitoring of subsurface contamination using laser fluorescence provides comprehensive reference material for researchers and engineers as well as engineering consultants interested in subsurface monitoring techniques or further development of this technology. It describes innovative technology that focuses on finding cost-effective solutions for site assessment and remediation.

Download or read the book Soil Vapor Extraction Using Radio Frequency Heating written by Donald F. Lowe and published by CRC Press. This book was published on 1999-12-06 with a total of 374 pages. Available in PDF, EPUB and Kindle. Excerpt from the book: One of the most commonly used techniques to treat soil contaminated with volatile organic compounds, soil vapor extraction (SVE) can also be applied to semi-volatile organic compounds (SVOC) if the soil is heated, by applying electromagnetic energy to radio frequency (FR) range, to increase the vapor pressure of the pollutant. Although RF-SVE systems used in previous field demonstrations have had varying degrees of success, questions remain regarding their viability and cost-effectiveness. Soil Vapor Extraction Using Radio Frequency Heating: A Resource Manual and Technology Demonstration covers detailed scientific and engineering information that answers these questions. The book includes the necessary databases, equations and calculation examples for RF heating. The included theoretical and practical information will facilitate future testing of RF-SVE soil treatments. Additionally, the book provides information for the comprehensive engineering design of potential RF-SVE applications. The authors use this information to examine predicted performance, magnitude of costs, and design changes that can reduce costs. Soil Vapor Extraction Using Radio Frequency Heating: A Resource Manual and Technology Demonstration provides an economic analysis of this innovative technology and discusses other possible applications.

This book was published on April 22, 2014 with a total of 713 pages. Available in PDF, EPUB and Kindle. Book Excerpt: The purpose of this book is to help engineers and scientists better understand groundwater contamination by dense non-aqueous liquid (DNAPL) contamination and the methods and technology used for characterization and remediation. Remediation of DNAPL source zones is very difficult and controversial and must be based on the most up-to-date knowledge of the behavior (transport and fate) of non-aqueous phase fluids in the subsurface and the specific geology, chemistry and hydrology of the site. This volume focuses on the characterization and remediation of nonaqueous phase chlorinated solvents, and we hope that mid-level engineers and scientists will find this volume useful in understanding the current state of DNAPL source zone management and remediation practices.
