Air sparging technology: State of the art in air sparging technologies
- Envirogen, Inc., Lawrenceville, NJ (United States)
In situ air sparging is a remediation technology primarily applied to the removal of volatile organic contaminants (VOCs) or biodegradable organic compounds from ground water aquifers. Conceptually, IAS is simple: clean air is injected into the aquifer beneath the water table to induce mass transfer of contaminants to the vapor phase and mass transfer of oxygen to the aqueous phase. IAS usually is used in conjunction with soil vapor extraction to control the migration of sparged contaminants in the vadose zone. This paper will present an update on air sparging in a number of areas including the applicability of air sparging, air flow in porous media, ground water mounding and hydraulics, aquifer clogging, biological degradation and pilot testing for radius of influence.
