Surfactant Enhanced Remediation Technologies A division of Ethical Solutions LLC Dan Socci, CEO ETHICALCHEM BACKGROUND (Surfactant Enhanced Product Recovery) • S-ISCO (Surfactant-enhanced In Situ Chemical Oxidation) Field Proven Technologies 50+ . Results from the application of Chlorinated Solvent Dense Non-Aqueous Phase Liquid (DNAPL) source remediation technologies and applications under different site conditions in order to initiate the development of guidelines on DNAPL source treatment. Bi-fold brochure describing the Surfactant-Enhanced Aquifer Remediation (SEAR) technique. As participant in the Nort Pest Clean project concerning remediation of the toxic chemical waste depot at Høfde 42, different surfactant formulations will be experimentally evaluated in laboratory tests for their ability to solubilize and mobilize the residual NAPL from the site and for their ability to enhance the planned alkaline hydrolysis.

Surfactant Enhanced Aquifer Remediation (SEAR), in its most basic form, could thus be considered a chemical enhancement to pump and treat. A chemical solution is pumped across a contaminated zone by introduction at an injection point and removal from an extraction point.
In summary, surfactant-enhanced pump-and-treat remediation is effective for DNAPL chemicals with relatively low aqueous solubilities, but requires surfactant reuse to be economical.

Surfactant-enhanced aquifer remediation (SEAR) is widely considered a promising technique to remediate dense nonaqueous phase liquid (DNAPL) contaminations in-situ.
The costs of a SEAR remediation are important and depend mostly on the setup of the remediation. Costs can be associated with the installation of injection and extraction wells, the required time of the remediation (and thus Cited by: &EPA United States Environmental Protection Agency National Surfactant-enhanced DNAPL remediation book Management Research Laboratory Ada, OK Research and Development EPA//S/ August ENVIRONMENTAL RESEARCH BRIEF Surfactant-Enhanced DNAPL Remediation: Surfactant Selection, Hydraulic Efficiency, and Economic Factors David A.

Metadata Show full item record. Abstract. Surfactant enhanced recovery is used most often where the groundwater is contaminated by dense nonaqueous phase liquids (DNAPLs).
These dense compounds, such as trichloroethylene (TCE), sink in groundwater because they are heavier than water. They then act as a continuous source for contaminant plumes that can stretch for miles within an aquifer.

Surfactant-Enhanced Remediation Surfactants, or surface-active agents, are chemical compounds that have the potential to alter the properties of fluid interfaces. Surfactant usage dates back to the s when sulfonate surfactants attained widespread use for enhanced oil recovery efforts.
Use in environmental applications dates to the s. DNAPL recovery, due to their inability to mobilize entrapped solvents and the generally low solubility of these organic liquids.
