ABSTRACT:
A soil remediation system uses heat from remediated soil to vaporize volatiles from contaminated dust without pollution. Preferably, this remediation takes place in a dust remediator which is located proximate a primary treatment unit for contaminated soil, which vaporizes volatiles from the dust using heat from remediated soil, and which directs the volatiles into the primary treatment unit for oxidation. The primary treatment unit may comprise a rotary drum, and the dust remediator may comprise a shroud covering the remediated soil outlet end of the drum and receiving the remediated soil and the dust. The remediated soil and the dust are combined in the shroud so as to maximize vaporization of contaminants while minimizing agitation of the dust, and the combined soil and dust are then discharged together from a remediated products outlet of the shroud.
