Improve Soil Flushing and LNAPL Removal with Petrox EC

Petrox EC is a product that combines a surfactant with petroleum-degrading microbes to improve separate phase oil recovery and bioremediation of residual oil.  The combined approach improves the rate of oil removal from soil and other subsurface media and establishes a beneficial petroleum-degrading microbial population that will treat tightly bound or deeply penetrated oil.

Petrox EC has been used in combination with periodic LNAPL extraction by pumping or bailing.   In field applications the surfactant effect has increased the LNAPL recovery rate by more than 10 fold.

Petrox EC has also been used to improve the efficiency of air sparging by flushing oil from the sediment surface for sparging and vapor phase recovery.
