Electrokinetic remediation of salt impacted sites

本项目的目标是开发一种新的低成本的原位修复技术，该技术基于在紧密间隔的渗透电极之间施加电场来处理高盐度污染的土壤。该项目将包括实验室和现场规模的实验。实验室规模的实验将研究电极几何形状和材料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传感器探针，这些探针将在现场实验期间用于监测药物过程。设计、制造和部署现场可部署的自主操作系统，以验证在实验规模上获得的结果。该现场试验的数据和结果将用于远程盐渍土壤的电动修复实施，并将导致该技术在加拿大西部不同公司的建立，首先是帝国石油公司。该项目将促进对富含粘土的土壤中电动离子传输的了解，并阐明传输现象、电极几何形状和用于构建它们的材料之间的关系。该项目代表了石油和天然气行业中用于修复受盐影响场地的自主系统的第一个例子。

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.
