Description
Surfactant-enhanced or cosolvent-enhanced ground water remediation remains one of the most promising extensions to pump-and-treat technology for contaminant source removal. This technology has proven effective in field demonstrations for the enhanced removal of both LNAPLS and DNAPLS. The cost of the surfactant and above ground fluid treatment presents the most serious impediment to full-scale application of this technology. Reuse of Surfactants and Cosolvents for NAPL Remediation provides the results of a field demonstration of an economical in situ treatment for NAPL remediation.
The field demonstration focused on the recovery of surfactants ready for reuse and included the following objectives:
Evaluate the technologies that recover surfactants for reuse in aquifer remediation
Demonstrate the most promising treatment at a field site
Perform economic analyses for the pilot-scale and full-scale in situ surfactant-aided soil flushing technologies
Estimate potential performance and applicability of the in situ surfactant-aided technologies
Recovery and reuse of surfactants used in site remediation can substantially improve the overall economics. Prior to this project, it had not been demonstrated that a surfactant recovery process could be reliably designed and operated at field conditions. Nor had the question of the most cost effective surfactant recovery scheme been addressed. Reuse of Surfactants and Cosolvents for NAPL Remediation highlights innovative and cost effective technologies for ground water remediaiton.
