Electrokinetic decontamination of millpond sludge
- Cleveland State Univ., OH (United States)
Electrokinetic decontamination of high clay containing soils is a developing technology. EPA has recently designated electrokinetic method as a viable insitu process and interested parties are attempting to apply this method at contaminated sites which have inherently low permeability soils and otherwise difficult to remediate. Electrokinetic process induces a high water flow rate in clayey soils by the mechanism known as electro-osmosis and is primarily suitable for heavy metal removal. However, chemical reactions and sorption of metal ions within the soil matrix may adversely effect the decontamination process. Presence of a significant amount of heavy molecular weight organic matter within the soil pores may reduce the mobility of the heavy metals due to the formation of insoluble organometallic compounds. There has been some research in removing heavy metals and low concentration organic matter from soil by the electrokinetic method. The effects of soil organic matter on heavy metal removal by electrokinetic method has not been adequately investigated and several unanswered questions remain about the efficiency of the process under such circumstances. This paper is a partial result of an electrokinetic decontamination investigation for Zn, Ph and Mn removal from a soil with high organic matter content. A foundry millpond sludge from North East Ohio was chosen as a high organic matter containing matrix.
