Cost And Performance Report. Use of Prepump Separation Technologies to Enhance Cost-Effectiveness of Bioslurper Systems: Long Term Demonstration.

Abstract

Bioslurping is a demonstrated technology for removing light, nonaqueous-phase liquid (LNAPL) from contaminated aquifers. It combines vacuum-assisted LNAPL recovery with bioventing and soil vapor extraction (SVE) to simultaneously recover LNAPL and bioremediate the vadose zone. A conventional bioslurper system withdraws free-phase LNAPL from the water table, groundwater, and soil vapor in a single process stream, using the air lift created by an aboveground liquid ring pump. The recovered LNAPL is separated from the groundwater and may be recycled. The recovered groundwater and soil vapor usually are treated and discharged. Because bioslurping enhances LNAPL recovery in comparison to conventional skimming and pump-drawdown technologies, bioslurping potentially can save the U.S. Department of Defense (DoD) significant funds by reducing the amount of time required to remediate LNAPL-contaminated sites.
