The goal of this project to develop a new low-cost in-situ remediation technique based on the use of an electricfield applied among closely spaced permeable electrodes to treat high salinity contaminated soil. The projectwill include both laboratory and field scale experimentation. Laboratory bench-scale experiments willinvestigate the effect of electrode geometry and material selection on the process efficiency. During this phaseof the project, we will also test and select suitable industrial pH sensor probes that will be used to monitor theremedial process during the field experimentation. A field-deployable system configured to operateautonomously will be designed, fabricated and deployed in a trial designed to validate the results obtained atbench scale. Data and results from this field trial are of use in the implementation of electrokinetic remediationof remote salt-impacted soils and will lead to the establishment of this technology for different companies inWestern Canada, starting with Imperial Oil. This project will enable advancements in the knowledge ofelectrokinetic ion transport in clay rich soils and cast light on the correlation between transport phenomena,electrode geometry and the materials used to build them. This project represents the first example of anautonomous system for the remediation of salt impacted sites in the oil and gas industry.

本项目的目标是开发一种新的低成本原位修复技术，该技术基于在紧密间隔的可渗透电极之间施加电场来处理高盐度污染土壤。该项目包括实验室和现场规模的实验。实验室工作台规模的实验将调查电极的几何形状和材料的选择对工艺效率的影响。在项目的这一阶段，我们还将测试和选择合适的工业pH传感器探头，用于在现场实验期间监测中间过程。将设计、制造和部署一个可配置为自动操作的现场部署系统，并进行试验，以验证在实验室规模获得的结果。该现场试验的数据和结果可用于远程盐影响土壤的电动修复，并将为加拿大西部的不同公司建立这种技术，从帝国石油公司开始。该项目将促进在富含粘土的土壤中电动离子传输的知识，并揭示传输现象，电极几何形状和用于构建它们的材料之间的相关性。该项目代表了第一个例子的自治系统修复盐影响的网站在石油和天然气工业。
