There are many technologies available for treatment of oil contaminated soils. The decision about choosing the specific method and equipment is made with consideration for site characteristic, soil condition, type and amount of contaminant, age of contamination, regulatory requirements, cost, time and others.
The current technologies may be placed in the group of ex-situ or in-situ process and further classified as physical, chemical and biological processes.
Physical/Chemical processes include Thermal Desorption, Incineration, Soil Washing, Chemical Treatment, Chemical Extraction, Volatilization, Steam Extraction, Solidification/Stabilization, Encapsulation, and a few other less common methods.
Biological processes may be ex-situ or in-situ and include Bioremediation/Bioreclamation, Bioventing, Bioslurping, Bioinjection and few others.
Soil excavation with subsequent thermal desorption is one of the most efficient methods for treatment of heavy petroleum contaminated soils. Contaminated soil is heated away from air so that organic contaminants are converted from solid to gaseous phase. It promotes separation of the petroleum contaminants from treated soil.
INKAS® Environmental Protection Ltd in cooperation with our partners supplies and installs the most advanced thermal desorption units available on the market, and organizes training of your personnel.
