Reactive barriers for the remediation of fluoride contamination in groundwater

该项目将建造第一个中试规模的方解石渗透反应屏障，用于修复VAW铝厂地下水中的氟污染。在VAW，氟污染地下水的浓度高达3000 mg/L，远远高于饮用水指标值1.5 mg/L。屏障的设计将基于VAW之前的SPIRT项目和顺式反应系统的实验室工作，该实验室已证明方解石可以去除水中99%的氟污染。该项目将在现场范围内证明这项技术，并为其应用于其他污染物提供基础。

This project will build the first pilot scale calcite permeable reactive barrier for the remediation of fluoride contamination in groundwater at VAW aluminium. At VAW, fluoride has contaminated groundwater at concentrations up to 3000mg/L, levels far higher than the drinking water guideline value of 1.5mg/L. The barrier design will be based on laboratory work from a previous SPIRT project with VAW and the CIs which has shown that calcite can remove 99% of fluoride contamination from water. The project will prove the technology at the field scale and provide the basis for its application to other contaminants.
