The objective of the proposed research is to explore new applications in solving environmental and public health problems, in the following electrokinetic research programs: 1) EK advanced treatment of sludge and wastewater, 2) EK energy recovery from hazardous waste, 3) EK control processes in acidic sulphate soils, 4) EK remediation of brownfields and industrial disposal sites. The results from the first program will be particularly useful for upgrading the plants with primary treatment, or plants having a low efficiency of biological processes. The contribution to the knowledge might have an impact on current legislations on the management of wastewater/sludge in Canada. The second program will to the development of technologies that will permit on extractions of organic liquid fractions and simultaneous metal removal from oily waste in order to its further application as a clean sustainable New Fuel. It is expected that the proposed research will result a revitalization of industrial sludge. The results from third program area will have an important impact, since they will lead to: a) development of in-situ remediation techniques permitting the protection of infrastructures; b) development of special drainage systems for AMD and ASS; c) generated knowledge that would be applied to advanced research on new remediation actions for ASS and AMD. Fourth program deals with an application of EK combined with other processes to advance the knowledge and develop new methods for the remediation of brownfields containing organic and inorganic pollutants. It is expected that the methodology will find a direct application: a) to ponds with petroleum sludge, b) in the formation of natural barriers around contaminated areas for cleanup of runoff, c) in the formation of strips in ditches for runoff collection, and d) into landfarming areas. Then, the impact of brownfields and contaminated sites within urban areas will deplete, and public health will improve.

拟议研究的目标是探索在解决环境和公共健康问题方面的新应用，包括以下电动研究计划：1)EK污泥和废水的深度处理，2)EK从危险废物中回收能量，3)酸性硫酸盐土壤中的EK控制过程，4)棕地和工业处置场地的EK修复。第一个项目的结果将对升级初级处理工厂或生物处理效率较低的工厂特别有用。对知识的贡献可能会对加拿大目前关于废水/污泥管理的立法产生影响。第二个计划将致力于开发允许从含油废物中提取有机液体馏分并同时去除金属的技术，以便将其作为一种清洁、可持续的新燃料进一步应用。预计拟议中的研究将导致工业污泥的振兴。第三个方案领域的成果将产生重要影响，因为它们将导致：a)开发能够保护基础设施的就地修复技术；b)开发针对AMD和ASD的特殊排水系统；c)产生可应用于ASD和ASD新补救行动的高级研究的知识。第四个方案涉及EK与其他工艺相结合的应用，以增进对含有有机和无机污染物的棕地的修复知识并开发新的方法。预计该方法将直接应用于：a)有石油淤泥的池塘；b)在受污染地区周围形成天然屏障以清除径流；c)在沟渠中形成条带以收集径流；以及d)在农田地区。然后，城市地区内棕地和受污染场地的影响将会耗尽，公共卫生将会改善。
