SEB Surfactant Enhanced Bioremediation process successfully cleans >4,000 Tons of F3 and F4 hydrocarbon contaminated soils at a remote site in Alberta.

The SEB process was employed when the subject soils would not respond well to a conventional ex-situ bioremediation treatment. So after a 20 month period of unsuccessful bioremediation; the client and environmental contractor contacted Ivey International Inc. to apply their newSEB process, which has gained a good reputation as an effective tool forimproving heavy-end (F3 & F4) hydrocarbon bioremediation by making the contaminants more Bio-Available to the soil bacteria.

SCOPE: The project goal was to improve the conventional bioremediation process with SEB to achieve the CCME soil clean-up objectives by October of 2006. After application of SEB in mid July 2006, thesoils were successfully treated within 4 months to achieve the F3 and F4 CCMEsoil clean-upgoals.The projectwasasuccessusingSEB!

The principle behind theSEB process is liberation of the sorted contaminants off the soils surfaces making them more Bio-Available to the bacteria for mineralization. Typically >95% of all contaminants are sorbed to the soil matrix making them less available to bacteria.This is illustrated below.
