ABSTRACT:
A process system for removal of toxic volatile organic compounds (VOCs) from contaminated groundwater is described. This process system involves groundwater pumping, groundwater treatment by air stripping in an enclosed sparging aeration chamber, air purification by granular activated carbon contactor, and recycling of GAC-purified air for further groundwater treatment by air stripping. The process system is cost-effective and eliminates the problem of secondary air contamination caused by conventional air stripping process.
