§ It is an in situ/on-site process developed by the R&D department of Serfim Decontamination.
§ The R&D project allowed selecting the most favorable and resistant plant to grow in contaminated soils, as well as selecting different bacteria depending on the type of contaminant.
§ BIO Technique: To favor the development of the roots of plants and the development of hydrocarbon degrading bacteria.
§ Applications: With or without landfarming - With or without bacteria, specially in big areas.
LANDFARMINGWITHPLANTS
Au Port E. Herriot
Landfarming with plants in Le Pontet (France)
§ Initial phase for delimitation and excavation of contaminated soils.
§ Initial concentrations of TPH (C6 -C40):
§ Maximum of 20.000 ppm (mg/kg)
§ Medium of 5.000 ppm
§ Objective: Less than 2.000 ppm
LANDFARMINGWITHPLANTS
§ Landfarming preparation according to the available surface and batch treatment with a similar degree of contamination.
§ Extension of seeds, nutrients and bacteria, according to these concentrations.
