-Bioremediation of soil & water body contaminated by Toluene and other PAHs.
-Gram positive bacteria isolated from natural environment.
1. Applied Field of Industrial and Applied Businesses
(Applicable Business):
Restore polluted underground water environment and contaminated soil by toluene (petroleum chemical product): Petroleum chemical complex, electronics industry aircraft part industry, cleaners etc.
2. Present treatment methods and problems
Mostly, it’s been treated by physical cleaning, reclaiming, burning and chemically neutralized. Some of thesis about biological treatment but, we assume there is none that has been commercialized.
3. Principal functions and expectable effects.
1) It is product formed with many kinds of congregated bacteria and it has excellent dissolving ability.
2) Expectable efficiency of 90~99%
4. Comparison with other product
There are physical and chemical treating products but they have demerit of uneconomic compare to bio product and caused second environment pollution and merit of requiring short treatment period
