  • Apparatus for bioremediation of sites contaminated with hazardous substances
    Patent number: 5080782
    Abstract: Disclosed is an apparatus and method for the continuuous bioremediation of sites contaminated with a hazardous substances. The apparatus includes a subsurface pumping system, for removing the hazardous substance contained in a phase separate from groundwater, which is integrated with a means for microbiologically treating the contaminated site. The means for microbiologically treating the contaminated site preferably includes hazardous substance degrading microorganisms.In operation, a subsurface pumping system separates, either above or below-ground, a free-product phase from the contaminated groundwater. The separated free-product is stored for off-site disposal. Contaminated groundwater is fed into the microbiological treatment system for further treatment and eventual recirculation into the contaminated site.
    Type: Grant
