Abstract
The article summaries results from research, development, and applications of an integrated technol- ogy for bioelectrical remediation of petroleum-hydrocarbon-based contaminants (gasoline, BTEX, diesel, heavy oil). The remediation occurs as a result of electro-osmotic transfer of the contaminated liquids, hy- draulic-based filtration, biodegradation of the petroleum-hydrocarbon contaminants, and gas-vaporization of the light fractions. The efficiency of the phenomena’s is in correlation with the parameters of the soil and the concentration of the contaminants; it can be controlled in the process of remediation. The technology is de- scribed in two different forms of applications: in-situ treatment and ex-situ treatment. The technology is test- ed in one pilot demonstration project and three full-scale projects for soil remediation of gas stations. The results of the research and development confirm the applicability of the integrated bioelectrical technology in different seasons and for all possible soils.
