Description:
In situ vitrification (ISV) uses electrical power to heat and melt soil, sludge, mine tailings, buried wastes, and sediments contaminated with organic, inorganic, and metal-bearing hazardous wastes. The molten material cools to form a hard, monolithic, chemically inert, stable glass and crystalline product that incorporates and immobilizes the thermally stable inorganic compounds and heavy metals in the hazardous waste. The slag product material is glass-like with very low leaching characteristics. Organic 'wastes are initially vaporized or pyrolyzecf by the process. These contaminants migrate to the surface where the majority are then burned within a hood covering the treatment area; the remainder are treated in an off gas treatment system.
