Download or read book Permeable Reactive Barrier written by Ravi Naidu and published by CRC Press. This book was released on 2018-10-08 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: Remediation of groundwater is complex and often challenging. But the cost of pump and treat technology, coupled with the dismal results achieved, has paved the way for newer, better technologies to be developed. Among these techniques is permeable reactive barrier (PRB) technology, which allows groundwater to pass through a buried porous barrier that either captures the contaminants or breaks them down. And although this approach is gaining popularity, there are few references available on the subject. Until now. Permeable Reactive Barrier: Sustainable Groundwater Remediation brings together the information required to plan, design/model, and apply a successful, cost-effective, and sustainable PRB technology. With contributions from pioneers in this area, the book covers state-of-the-art information on PRB technology. It details design criteria, predictive modeling, and application to contaminants beyond petroleum hydrocarbons, including inorganics and radionuclides. The text also examines implementation stages such as the initial feasibility assessment, laboratory treatability studies (including column studies), estimation of PRB design parameters, and development of a long-term monitoring network for the performance evaluation of the barrier. It also outlines the predictive tools required for life cycle analysis and cost/performance assessment. A review of current PRB technology and its applications, this book includes case studies that exemplify the concepts discussed. It helps you determine when to recommend PRB, what information is needed from the site investigation to design it, and what regulatory validation is required.

Book excerpt: Remediation of ground water is complex and often challenging. The passive remediation technology, currently in vogue, is based on permeable reactive barriers (PRB) that allow water to pass through while the fence/barrier made of reactive materials remediates the contaminants. Although PRB has been in operation for over a decade there are limited published books available. This book covers in one single volume all the information needed to plan, design/model and apply a successful, cost-effective and sustainable PRB technology.

Download or read book Permeable Barriers for Groundwater Remediation written by Arun R. Gavaskar and published by . This book was released on 1998 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of the limitations of conventional pump-and-treat systems in treating groundwater contaminants, permeable barriers are potentially more cost-effective than pump-and-treat systems for treating dissolved chlorinated solvent plumes, which may persist in the saturated zone for several decades. Other contaminants, such as chromium or other soluble heavy metals, can also be treated with this technology. Permeable Barriers for Groundwater Remediation discusses the types of permeable barriers, their design and construction, and how they can be monitored to evaluate compliance. It provides practical guidance on reactive media selection, treatability testing, hydrogeologic and geochemical modeling, and innovative installation techniques for the evaluation and application of this promising new technology. The types of permeable barriers discussed include: trench-type and caisson-based reactive cells; innovative emplacements, such as horizontal trenching and jetting; and continuous reactive barriers versus funnel-and-gate systems.

Download or read book Long Term Performance of Permeable Reactive Barriers written by K.E. Roehl and published by Gulf Professional Publishing. This book was released on 2005-04-27 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: While extensive research has been performed on many technological aspects of permeable reactive barriers and a number of contaminants have so far been successfully treated by PRB systems, long-term performance has not been extensively considered and little is known about the processes influencing long-term behaviour. This gap in our knowledge is all the more disadvantageous as design life has a decisive influence on the economic viability of PRBs. The book describes methods for evaluation and enhancement of the long-term performance of PRB systems, especially of those targeting heavy metals, specifically uranium, and organic contaminants by sorption and/or precipitation mechanisms. Major topics in the book are: - Selection and characterisation of suitable reactive materials - Characterisation of the relevant contaminant attenuation processes - Developing new contaminant-binding chemical compounds ("ligands") - Accelerated testing methods to assess the long-term performance of the attenuation mechanisms in PRBs - Evaluation of the influence of site characteristics on PRB performance - Monitoring of existing and new field installations - Coupling of electrokinetic techniques and PRB systems - Large-scale laboratory and field tests and their results It addresses the long-term performance of PRBs, an important feature of this novel remediation technology, systematically. It deals extensively with heavy metal removal, with special emphasis on uranium. A number of case studies, experiences with large-scale modelling and test site experiments provide insight into the practical application of the results. This volume will contribute to the science underpinning groundwater remediation, and this will result in the improvement of quality of life and health and safety.* A systematic approach to investigating the long-term performance of permeable reactive barriers* Development of new contaminant-binding chemical compounds ("ligands"), accelerated testing methods to assess the long-term performance, and efficiency enhancing electrokinetic techniques* Extensive data and information on a Hungarian uranium mining facility; once a carefully kept secret of the Soviet Union

Download or read book Advanced Treatment Technologies for Fluoride Removal in Water written by Akhilesh Kumar Yadav and published by Springer Nature. This book was released on 2024-01-01 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents an overview of the techniques available today for the removal of fluoride contamination/pollutants/species from water. Also covered are traditionally applied techniques for the removal of fluoride pollutants/species, including oxidation, coagulation-flocculation, and membrane techniques. Recently, progress has been made on the utility of various nanoparticles for the extraction of contaminants from water. Fluoride contamination is affecting water resources quality worldwide as a result of human activities, such as mining and pesticide use. Due to the high risk of fluoride exposure, specific water treatment processes are required to meet more severe water quality standards. A better understanding of currently available processes is necessary to develop economical, efficient, and effective methods for fluoride removal. Fluoride can either be coated, adsorbed using a wide range of both mineral and organic constituents or can be directly rejected by membrane processes, such as reverse osmosis and nanofiltration. Recent developments of submerged hybrid membrane systems, such as membrane bioreactors in wastewater treatment, provide alternative technologies for fluoride treatment.

Download or read book Advanced Nano Bio Technologies for Water and Soil Treatment written by Jan Filip and published by Springer Nature. This book was released on 2020-01-17 with total page 656 pages. Available in PDF, EPUB and Kindle. Book excerpt: We are proposing this comprehensive volume aimed at bridging and bonding of the theory and practical experiences for the elimination of a broad range of pollutants from various types of water and soil utilizing innovative nanotechnologies, biotechnologies and their possible combinations. Nowadays, a broad range of contaminants are emerging from the industry (and also representing old ecological burdens). Accidents and improper wastewater treatment requires a fast, efficient and cost-effective approach. Therefore, several innovative technologies of water and soil treatments have been invented and suggested in a number of published papers. Out of these, some nanotechnologies and biotechnologies (and possibly also their mutual combinations) turned out to be promising for practical utilization – i.e., based on both extensive laboratory testing and pilot-scale verification. With respect to the diverse character of targeted pollutants, the key technologies covered in this book will include oxidation, reduction, sorption and/or biological degradation. In relation to innovative technologies and new emerging pollutants mentioned in this proposed book, an important part will also cover the ecotoxicity of selected pollutants and novel nanomaterials used for remediation. Thus, this work will consist of 8 sections/chapters with a technical appendix as an important part of the book, where some technical details and standardized protocols will be clearly presented for their possible implementation at different contaminated sites. Although many previously published papers and books (or book chapters) are devoted to some aspects of nano-/biotechnologies, here we will bring a first complete and comprehensive treatise on the latest progress in innovative technologies with a clear demonstration of the applicability of particular methods based on results of the authors from pilot tests (i.e., based on the data collected within several applied projects, mainly national project “Environmentally friendly nanotechnologies and biotechnologies in water and soil treatment” of the Technology Agency of the Czech Republic, and 7FP project NANOREM: “Taking Nanotechnological Remediation Processes from Lab Scale to End User Applications for the Restoration of a Clean Environment”). This multidisciplinary book will be suitable for a broad audience including environmental scientists, practitioners, policymakers and toxicologists (and of course graduate students of diverse fields – material science, chemistry, biology, geology, hydrogeology, engineering etc.).

Download or read book Advanced Water Supply and Wastewater Treatment A Road to Safer Society and Environment written by Petr Hlavinek and published by Springer Science & Business Media. This book was released on 2011-01-07 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stable, safe, secure and readily available water supply is one of the key factors in ensuring a good level of the public health and a stable society. Scientific assessments show that about 80 % of diseases and one-third of the total death toll in the developing countries are caused by the low quality of the drinking water. Other countries are also suffering from water shortages and insufficient quality of the drinking water. Many rivers in Europe and in other parts of the world are significantly polluted by insufficiently treated or untreated wastewater discharge. This book is based on the discussions and papers prepared for the NATO Advanced Research Workshop that took place in Lviv, Ukraine, and addressed recent advances in water supply and wastewater treatment as a prerequisite for a safer society and environment. The contributions critically assess the existing knowledge on urban water management and provide an overview of the current water management issues, especially in the countries in transition in Central and Eastern Europe and in the Mediterranean Dialogue countries.
