Extraction (MPE), also known as MEME (mobile, enhanced multi-phase
extraction), remediates contaminants in multi-phases such as aqueous liquid, non-aqueous liquid,
and gas to clean up sites in a fraction of the time of other
technologies. The technology
involved is considered the state-of-the-art in groundwater remediation.
MPE systems remove vapors and liquids simultaneously from the subsurface.
Ambient air (5 to 20 cubic feet per minute) is drawn down the casing of
monitoring wells, across the groundwater interface, and back up a drop tube,
providing the necessary lift to extract subsurface groundwater. An airflow gauge
attached to a well head is used to measure the amount of ambient air, which is
subtracted from the total flow. Additionally, vacuum gauges are used to measure
the extraction vacuum, as well as the vacuum applied to the subsurface
The extracted vapors and liquids are
transferred to a mobile treatment
system, where the liquids are
separated and discharged into a
storage tank for proper disposal.
Soil vapors are transferred to a
forced air thermal oxidation (ThOx)
unit and incinerated at
approximately 1,500 degrees
Fahrenheit. The treated air is then
discharged into the atmosphere.
