Abstract

Simultaneous plume control and subsurface treatment technologies are receiving increasing attention in site remediation. In this paper computer modeling and laboratory pilot scale results are presented to demonstrate the effectiveness of the Trench Bio-Sparge (TBS) system for in-situ treatment of groundwater contaminated with organic compounds. The TBS technology achieves simultaneous hydraulic control and treatment by directing the contaminated plume through a subsurface reactor where groundwater treatment is accomplished by physical or biological means or combinations thereof. Plume capture is achieved by a set of diversion wing walls. Specifically it is demonstrated that velocity equalization is necessary to attain uniform residence time distribution in the reactor. The modeling studies showed that the geometry of the plume diversion system is very important in the design of an efficient reactor. Results of laboratory studies are presented which demonstrate that very high treatment efficiency of organics can be achieved in relatively short reactors having short residence times. Experiments performed with phenol and BTEX contaminated groundwater demonstrated overall removal efficiencies exceeding 99.0%.
