Pilot-scale Installation for Remediation of DDT-contaminated Soil

Abstract

An effective remediation method of DDT-contaminated soil was developed. The preliminary results of investigations on a laboratory scale were exploited to scale up the technology into pilot scale. The approach for soil remediation was based on the utilization of hydroxyl radicals that were generated from water aerosol and ozone in a fluidized bed reactor. During the remediation procedure the level of soil contamination was reduced by 80%. The procedure was successfully scaled up; no degradation products were detected and the total organic carbon was preserved.
