MONTROSE SUPERFUND SITE LOS ANGELES, CALIFORNIA FINAL ELECTRICAL RESISTANCE HEATING (ERH) PILOT TEST REPORT
Montrose Chemical Corporation of California, 126 pp, 2020

A pilot test combined ERH technology with a vapor recovery (VR) and treatment system to reduce mobile DNAPL mass to the extent practicable. The system used a single power control unit, one steam condenser and cooling tower, and a VR blower. Captured vapors were treated with a steam regenerated granulated activated carbon (SRGAC) unit and polishing vapor-phase granulated activated carbon units (VGAC). All process water was treated via liquid-phase granular activated carbon prior to discharge. The VR system operated for 153 days, and 659,299 kWh were applied to the treatment volume over a total period of 132 days of heating. Based on direct measurement of accumulated DNAPL and estimates of mass captured on polish VGAC, ~26,600 lbs of total VOCs were recovered from the treatment volume during ERH heating. A total of 2,519 gals of DNAPL were recovered by the SRGAC unit. Confirmatory sampling within the pilot test treatment volume indicated an average monochlorobenzene (MCB) mass reduction of 99.86%. Site-specific data collected during the pilot will be used to support the selection of a larger scale ERH system. https://semspub.epa.gov/work/09/100020452.pdf
