Multiphysics Implementation of Electrokinetic Remediation Models for Natural Soils and Porewaters
(Elsevier, 2017)
Models of electrokinetic soil remediation systems have been developed significantly in recent decades. A wide range of physicochemical phenomena occurs in this type of process, which makes it difficult to capture all of ...
ZVI – Reactive barriers for the remediation of soils polluted with clopyralid: Are they really Worth?
(Elsevier, 2018-10)
In this work, the remediation of soil spiked with clopyralid is evaluated using two types of zero valent iron (ZVI) barriers coupled with electrokinetic soil flushing (EKSF). These barriers consist of soil merged with iron ...
Influence of the Type of Surfactant on the Mobility of Flushing Fluids for Electro-Remediation Processes
(Taylor & Francis, 2011)
The mobility of four flushing fluids in an electro-remediation process has been studied. A mock-up plant with two rows of three electrodes positioned in semipermeable electrolyte wells was used in this study. Two different ...
An elastoplastic model of bentonite free swelling
(2014)
This article proposes a new plastification mechanism to model bentonite free swelling processes by using an elastoplastic approach. The formulation is based on an interaction function that defines the plastic macrostructural ...
Development of a multiphysics numerical solver for modeling the behavior of clay-based engineered barriers
(Elsevier, 2019-02)
This work describes the development of a numerical module with a multiphysics structure to simulate the thermo-hydro-chemo-mechanical behavior of compacted bentonites. First, the conceptual model, based on the state-of-the-art ...
Remediation of soils polluted with 2,4-D by electrokinetic soil flushing with facing rows of electrodes: A case study in a pilot plant
(Elsevier, 2016-02-16)
This study focuses on evaluating the application of electrokinetic soil flushing (EKSF) technologies to remediate soil polluted with 2,4-dichlorophenoxyacetic acid (2,4-D). This compound was selected as an example of polar ...
Removal of phenanthrene from synthetic kaolin soils by electrokinetic soil flushing
(Elsevier, 2014-08)
In this work, the scale up of the flushing-fluid-assisted electrokinetic remediation of kaolin soil polluted with phenanthrene has been studied. Three different scales have been used: lab (25 cm3), bench (28 × 103 cm3) and ...
Comparison of the hydrogeochemical and mechanical behaviours of compacted bentonite using different conceptual approaches
(Elsevier, 2017-06)
This study compares the capabilities of two numerical models that simulate the behaviour of compacted saturated MX-80 bentonite exposed to different chemical environments. Both codes have different approaches: one of them ...
Scale-up of electrokinetic permeable reactive barriers for the removal of organochlorine herbicide from spiked soils
(Elsevier, 2021-09-05)
This work aims to shed light on the scale-up a combined electrokinetic soil flushing process (EKSF) with permeable reactive barriers (PRB) for the treatment of soil spiked with clopyralid. To do this, remediation tests at ...
Differentiated intra- and inter-aggregate water content models of MX-80 bentonite
(2015)
The current research proposes a method for obtaining the intra-aggregate (microstructural) and inter-aggregate (macrostructural) water content of MX-80 bentonite using data from water retention curves. Data associated with ...
