The Art Technology Success in Treating Petroleum and Chlorinated Compounds, MTBE, and 1,4 Dioxane….How Does It Happen?
The ART Technology was proven effective in comprehensively treating contamination including BTEX, chlorinated compounds and recalcitrant constituents such as MTBE and 1,4 dioxane. The ART Technology has been implemented at sites worldwide.
The ART technology is based on verified concepts and combines in situ air stripping, air sparging, soil vapor extraction, enhanced bioremediation/oxidation and subsurface circulation. The multiple remediation concepts employed are well suited for recalcitrant compounds because the synergistic systems are attacking contaminants on a number of fronts. The multiple, in-well stripping passes and high air to water ratio achieved in the well are integral to the physical removal of contamination. Concurrently, the subsurface circulation process is actively flushes residual contamination from the soil matrix and mobilizes it back to the well for further treatment. The circulation and extraction processes also actively and continuously provide significant dissolved oxygen boost throughout the radius of influence, enhancing bioremediation of compounds.
ART will provide a workshop that focuses on the technical details of the ART In-Well Technology. The work shop will include an overview of the ART Technology and will detail typical components of an ART installation, technical concepts behind the technology and strength and limitations. The workshop will also contain a summary of site assessment and design parameters including site geology, hydrogeology, lateral and vertical extent of contamination and effects of inorganic compounds on design.
The workshop will also detail and practice ART Technology design and implementation aspects with emphasis on well design, sparging extraction rate and equipments sizing. Sampling and monitoring scenarios will also be discussed. The final minutes will be dedicated to answer questions. Material provided to participants will include technology summary papers, articles, third party and agency evaluation report, case history summaries and typical well and manhole designs schematics.
