摘要

Halogenated volatile organic solvents are found in the soil or groundwater at many former and active industrial sites. Fortunately highly effective remediation technologies are available to restore these former brownfields to a healthy state. The range of technologies includes the traditional approach where the contaminated soil is excavated and the volatile halogenated contaminants are thermally or atmospherically stripped, followed by thermal oxidation of the vapors and scrubbing of the formed acid gases. More recently developed advanced technologies, such as the one available from TerraTherm, Inc. avoids the needless costly and disruptive digging and instead removes the contaminants without soil excavation. Proven at various locations, around the world, the system uses electrical energy to heat the soil in place, volatilize the contaminants, and extract them under vacuum for treatment. Since these sites are remediated over a period of a few months, the equipment is designed to be set up, operated, dismantled and be moved to the next site.
