Common Treatment Train for Fuels


Courtesy of Courtesy of Federal Remediation Technologies Roundtable

A treatment train is the combination of different treatment technologies. A system diagram of a common treatment train for fuels is illustrated below. The fuel contaminated soil is first treated using a soil washing process. Water is injected at the up stream side of the contaminated site. Surfactant or other additives may be added to enhance the soil washing effect. Contaminated water is pulled out through extraction wells installed at the down stream side for further treatment. An in situ bioremediation process is used, following the initial soil washing, to complete the remediation. Nutrients and air may be pumped in to the site if necessary to enhance intrinsic bioremediation.
