Which among the following is NOT an example of In-situ bioremediation techniques? Correct Answer Biopiles
The Correct Answer is Option 4 i.e Biopiles.
- In situ bioremediation techniques:
- It involves the treatment of the contaminated material at the site.
- Example: Bioventing, Biosparging, Bioaugmentation.
- Ex Situ bioremediation techniques:
- It involves the removal of the contaminated material to be treated elsewhere.
- Example: Landfarming, Biopiles, Bioreactors, Composting.
- Bioventing: Supply of air and nutrients through wells to contaminated soil to stimulate the growth of indigenous bacteria.
- Biosparging: Injection of air under pressure below the water table to increase groundwater oxygen concentrations and enhance the rate of biological degradation of contaminants by naturally occurring bacteria.
- Bioaugmentation: Microorganisms are imported to a contaminated site to enhance the degradation process.
- Biopiles: It is a hybrid of landfarming and composting. Typically used for the treatment of surface contamination with petroleum hydrocarbons.
