In Situ flushing of contaminated soils from a refinery:

In situ flushing has been used to facilitate the removal of sorbed and deposited polycyclic aromatic hydrocarbons (PAHs), total petroleum hy- drocarbons (TPHs), and diesel fuel from soil materials (Abdul et al., 1990).The success of this technique can be attributed to the capacity of surfactants, at concentrations above the critic micellar concentration (CMC), to enhance the aqueous solubility of

Soil Washing Potential of a Natural Surfactant

Natural surfactant solutions were also employed for flushing HCB from one-dimensional soil columns. HCB recoveries after 12 pore volumes of flushing with 0.5 and 1% natural surfactant solutions were 20 and 100 times more than that recovered by water flooding. These promising results warrant further re.

Soil Washing, Ozofractionation and Metal Sequestration

Soil washing is based on the principle that a contaminant will bind to the soil"s fine particles, which in turn bind to coarser particles, and thus by separating the course fraction from the fine fraction using agitated fresh water, contaminants along with the finest soil fraction can be separated from the soil (a process called “soil partitioning”), thereby liberating contaminants from the course fraction. This
