Download or read book Electrochemically Assisted Remediation of Contaminated Soils written by M. A. Rodrigo and published by Springer Nature. This book was released on 2021-06-15 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an overview of the current development status of remediation technologies involving electrochemical processes, which are used to clean up soils that are contaminated with different types of contaminants (organics, inorganics, metalloids and radioactive). Written by internationally recognized experts, it comprises 21 chapters describing the characteristics and theoretical foundations of various electrochemical applications of soil remediation. The book’s opening section discusses the fundamental properties and characteristics of the soil, which are essential to understand the processes that can most effectively remove organic and inorganic compounds. This part also focuses on the primary processes that contribute to the application of electrochemically assisted remediation, hydrodynamic aspects and kinetics of contaminants in the soil. It also reviews the techniques that have been developed for the treatment of contaminated soils using electrochemistry, and discusses different strategies used to enhance performance, the type of electrode and electrolyte, and the most important operating conditions. In turn, the book’s second part deals with practical applications of technologies related to the separation of pollutants from soil. Special emphasis is given to the characteristics of these technologies regarding transport of the contaminants and soil toxicity after treatment. The third part is dedicated to new technologies, including electrokinetic remediation and hybrid approaches, for the treatment of emerging contaminants by ex-situ and in-situ production of strong oxidant species used for soil remediation. It also discusses pre-pilot scale for soil treatment and the use of solar photovoltaic panels as an energy source for powering electrochemical systems, which can reduce both the investment and maintenance costs of electrochemically assisted processes.

Download or read book Field Screening for Hexavalent Chromium in Soil written by and published by . This book was released on 1994 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sodium dichromate has been identified as a contaminant of concern at several waste sites on the Hanford Site. Although chromium standards for soil are typically stated in terms of total chrome, much of the toxicity and carcinogenicity are attributed to the hexavalent state, which typically exists as a relatively mobile anion. Investigation and removal of crushed drums potentially containing residual sodium dichromate required a field test for hexavalent chromium to support characterization and remediation activities. Previous experience with a commercially available field test kit had been unsuccessful. This stimulated an effort to determine potential sources of error in the field test and led to a number of modifications that significantly improved the reliability of the test.

This book was released on 2023-01-01 with total page 681 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes environmental remediation technologies to remove pollutants from the environment and the environmental materials used for remediation. The focus is on the functional design of environmental materials, especially to create materials for coping with a variety of pollutants in different concentrations and conditions. The authors present research highlights from their work in this area and aim to inspire the development of new concepts in environmental remediation. This work is a must-read for practitioners who are exploring restoration technologies and materials for solving environmental pollution as well as researchers and graduate students studying environmental remediation. A number of Asian researchers who have been engaged in these studies are among the authors, and this book will contribute to solving pollution problems in Asia as well as the rest of the world.

Available in PDF, EPUB and Kindle. Book excerpt: This book explores the treatability study of chromium and other heavy metals from contaminated soil and groundwater. The author provides an in-depth analysis of the various treatment methods and their effectiveness in removing chromium and other heavy metals from contaminated sites. The book discusses the sources of chromium contamination in soil and groundwater, the effects of chromium exposure on human health and the environment, and the regulatory guidelines for chromium levels in soil and water. The author also examines the different treatment methods available for chromium and heavy metal removal, including physical, chemical, and biological methods. The book focuses on the use of advanced oxidation processes (AOPs) for the treatment of chromium-contaminated soil and groundwater. The author explores the application of different AOPs, including photocatalysis, Fenton's reagent, and ozonation, and discusses their advantages and limitations. The book also covers the use of adsorption, ion exchange, and membrane filtration technologies for the removal of heavy metals from contaminated soil and groundwater. The author provides case studies and real-world examples to illustrate the effectiveness of different treatment methods and their applications in the field of environmental remediation. Overall, "Chromium Treatment from Contaminated Soil and Groundwater" is a valuable resource for researchers, scientists, and professionals working in the field of environmental remediation and pollution control.

Download or read book Reuse of Cold Top Ex situ Vitrified Chromium Contaminated Soils in Hot Mix Asphalt Concrete written by Gerald Charleston and published by . This book was released on 1998 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research investigated the pilot scale feasibility of the remediation of chromium contaminated soil through cold top ex-situ vitrification and the reuse of the vitrified products as highway construction aggregates. There are more than two million tons of chromite ore residues from the chromate extraction manufacturing leftover in Hudson County, New Jersey. They contained both un-leached hexavalent and unoxidized trivalent chromium. Hexavalent chromium is well known as a group A human carcinogen. It is also considered an environmental and health hazard. Of the many ex- situ and in-situ physical, chemical, and biological treatment technologies for chromate production waste, the ability to reduce hexavalent chromium to trivalent chromium and at the same time inhibit the reversal back to hexavalent chromium as well as being able to demonstrate long-term, low toxic metal leaching characteristics is a critical criteria for technology evaluation. Cold top ex-situ vitrification has been identified to satisfy the above criteria as a highly cost effective and environmentally sound physical treatment. The toxicity characteristic leaching process (TCLP) test results confirmed the effectiveness of the treatment technology. This research describes test results of the use of the vitrified material as aggregate in hot mix asphalt. The physical properties of vitrified chromium contaminated soils were compared with the New Jersey Department of Transportation (NJDOT) specifications for aggregates to evaluate the reuse potential as a construction material. The crushed vitrified contaminated soils met all the desired NJDOT specifications for aggregates. The inclusion of those aggregates in hot mix asphalt concrete produced NJDOT acceptable mix. The freeze/thaw and wet/dry durability tests and permeability tests produced acceptable values for specimens made from both mixes at optimum asphalt contents. From the test results it can be concluded that the vitrified material can be used in the production of asphalt concrete providing less than 60% vitrified material is included in the mix.
