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.
