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，该技术基于在紧密分布的可渗透电极之间施加电场来处理高盐分污染的土壤。该项目将包括实验室和现场规模的实验。实验室小试实验将考察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传感器探头，这些探头将在现场试验期间用于监测介质过程。将设计、制造和部署配置为自主运行的可现场部署系统，以验证在试验台规模上获得的结果。这项实地试验的数据和结果将用于实施偏远受盐分影响的土壤的电动修复，并将导致从帝国石油公司开始，为加拿大西部的不同公司建立这项技术。该项目将促进对富粘土土壤中电动离子迁移的认识，并阐明迁移现象、电极几何形状和用于构建它们的材料之间的关系。该项目是石油和天然气行业中用于修复受盐分影响的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.
