The groundwater will be pre-filtered before entering the air stripper, utilizing bag <br /> filter(s). The vapors from the air stripper will be routed to a thermal oxidizer, where temperatures in excess of <br /> 1,400 degrees F effectively combusts the hydrocarbon laden vapor. The destruction efficiency for the oxidizer is <br /> 99% or greater. <br /> The treated groundwater will be sent through activated carbon for final polishing to remove all remaining <br /> hydrocarbons, and then discharged to the Sewer system under the suitable permit. The treated water for <br /> discharge will be sampled and tested to confirm the hydrocarbons have been removed. <br /> The description above is provided by: <br /> Yarone (Ron) Madnick <br /> Project Engineer <br /> Ami Adini &Associates, Inc.
