DNAPL Extraction/Oleofilter Test Report

PDF Version Also Available for Download.

Description

A short term, low flow DNAPL extraction test was performed from May 29 - 30, 1997, to gather additional information about the possibility of using monitoring well MSB-3D to recover source contamination from the M-Area Aquifer. Although no visible, free phase material was recovered, the groundwater did contain perchloroethylene (PCE) at and above aqueous solubility. Improvements in the pumping configuration were identified for future trials. Prior to final treatment in the M1 air stripper, the groundwater was passed through an Oleofiltration system to evaluate its capability as a treatment technology. The Oleofilter uses a combination of conventional gravity assisted separation ... continued below

Description

A short term, low flow DNAPL extraction test was performed from May 29 - 30, 1997, to gather additional information about the possibility of using monitoring well MSB-3D to recover source contamination from the M-Area Aquifer. Although no visible, free phase material was recovered, the groundwater did contain perchloroethylene (PCE) at and above aqueous solubility. Improvements in the pumping configuration were identified for future trials. Prior to final treatment in the M1 air stripper, the groundwater was passed through an Oleofiltration system to evaluate its capability as a treatment technology. The Oleofilter uses a combination of conventional gravity assisted separation with coalescing plates and a final polishing filter using proprietary coated granules to remove hydrocarbons. Although free phase DNAPL was not processed through the Oleofilter, the groundwater containing high levels of dissolved PCE was treated efficiently. Initially the Oleofilter removed 99 percent of the PCE. As the test progressed, this removal rate decreased to 83 percent as the granules became loaded with PCE. Longer term testing, perhaps with periodic backflushing, is required to determine the effective granule capacity.
