Abstract

In this study, the solubilization of dense nonaqueous phase liquid (DNAPL) using oil-based emulsion was investigated for aquifer remediation. The micro-sized oil emulsion has large surface areas and buoyancy force, therefore it can be effective in treating DNAPL pool of the aquifer without downward migration of DNAPLs. The emulsion was prepared using silicone oil and mechanical homogenization. And the prepared emulsion had micro-sized similar distribution: 99 % in number and 80 % in volume were less than 10${\mu}{\textrm}{m}$. As target pollutants, trichloroethylene and 1, 2 dichlorobenzene were selected. All of used DNAPLs were solubilized successfully in oil-based emulsion. Even at low oil percentage, emulsion showed good solubility against pollutants. Therefore, the remediation using oil-based emulsion was considered as an effective alternative in dealing with DNAPLs of the aquifer.
