To present a performance summary of an advanced multifuel-capable combustion and melting system (CMS) for the vitrification of hazardous wastes,
Description:
A performance summary of an advanced multifuel-capable combustion and melting system (CMS) for the vitrification of hazardous wastes is presented. Vortex Corporation has evaluated its patented CMS for use in the remediation of soils contaminated with heavy metals and radionuclides under the EPA's SITE program and other waste treatment technology evaluation programs. The Vortec CMS has successfully demonstrated the ability to effectively treat hazardous and/or radioactive solis and produce a stable vitrified product with excellent leach resistance. The ability to process contaminated soils either as dry granular solids or in the form of a slurry has been demonstrated with a DRE of greater than 99.99% for organic compounds. All the glass produced passed the TCLP test with the concentration of contaminants the leachates significantly reduced from those of the corresponding feedbacks which did not pass TCLP. The vitrified product also demonstrated superior radionuclide leach resistance, as no detectable qauntities of the surrogate radionuclide were found by an ANSI/ANS-16.1 test.
