Study Notes
Bioremediation Techniques
- Solid-phase bioremediation treats contaminated soil on-site, maintaining the soil in its original location.
- Slurry-phase bioremediation is a slower method compared to other treatment techniques, potentially extending remediating timelines.
Mechanisms of Solid-Phase Bioremediation
- Bacterial growth in solid-phase bioremediation is enhanced by using pipes that distribute nutrients and facilitate microbial activity throughout the soil piles.
- Air pulling through these pipes is not essential for microbial respiration, indicating alternative respiration methods are employed by the microorganisms.
Biopile Bioremediation Process
- Biopile remediation involves creating above-ground piles of polluted soil, which allows for easier management and monitoring.
- This technique includes aeration to improve oxygen availability and nutrient amendment to support the growth of microbial populations, improving bioremediation efficacy.
