Download or read book Electrokinetic Barriers to Contaminant Transport Numerical Modelling and Laboratory scale Experimentation written by and published by . This book was released on 1908 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Vertical barriers such as cutoff walls, grout curtains or sheet piles are frequently used for containing the contaminants in place during remediation of contaminated soil and groundwater. The electrokinetic barrier is an emerging technique which can be used as a low-cost alternative for containing the spread of contaminants. An electrical potential gradient applied across the electrodes inserted in the subsurface could create an electro-osmotic counter gradient high enough to stop the flow of water due to the hydraulic gradient. A laboratory scale experiment was conducted to study the effectiveness of electrokinetic barriers in containing the spread of contaminants. Potassium chloride was used as a tracer to find the effectiveness of electrokinetic barriers. Laboratory-experiments in sandy clay soils showed that without electrokinetic barriers the K+ ions migrated at a rate of 2 mm.d -1 whereas, with the electrokinetic barriers the K+ ions migrated at a rate of 0.1 mm.d-1. Hence, electrokinetic barriers could be used as an effective system for preventing the spread of the contaminants in the subsurface. A two-dimensional finite element model was developed to investigate the contaminant migration under hydraulic, electrical, and chemical gradients. Migration of a pH front due to the electrolysis reactions at the anode and the cathode and development of non-linear hydraulic and electrical potential gradients brought about by the changes in the electrical properties of the soil could be simulated by the model developed in this thesis. The model results compared well with the experimental results. The numerical model developed in this thesis was also used to evaluate the effectiveness of different electrode configurations for possible field applications.

Download or read book Chemo Mechanical Couplings in Porous Media Geomechanics and Biomechanics written by Benjamin Loret and published by Springer Science & Business Media. This book was released on 2004-06-16 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book addresses fundamental issues faced by experimentalists, modelers and engineers interested in different physical, mechanical and transport aspects of biological tissues and chemically active geological materials, mainly clays and shales. The focus is on the couplings between electro-chemical and mechanical aspects involved in swelling and chemical consolidation. Emphasis is laid on the influence of these phenomena on mechanical properties and on transport properties. Applications in geo-environmental and geotechnical technologies, including nuclear and hazardous waste isolation, oil recovery, engineering geology, are addressed directly or implied. Control of long term effects of surgery and mechanical performance of prostheses may benefit from the modeling of irreversibilities that are of utmost importance in geological materials. Conversely, understanding the self-regulation mechanisms of biological tissues may be helpful in the design of efficient engineering materials.
