Study Notes
Bioremediation Process
- Bioremediation can take anywhere from a few months to several years
Ideal Conditions for Bioremediation
- Microorganisms: suitable kinds are required to biodegrade all types of contaminants
- Oxygen: at least 0.4 mg/liter in soil is necessary for aerobic biodegradation
- pH: optimal range is 6.5-7.5 for good microbial growth
- Temperature: between 0-40°C is ideal for microbial growth
- Nitrogen, phosphorus, sulphur, and other nutrients are required to support good microbial growth
- Moisture: 50-70% of the water holding capacity of the soil is optimal
Factors Affecting Bioremediation
- Size of the contaminated area affects the duration of bioremediation
- Concentration of contaminants affects the duration of bioremediation
- Conditions such as temperature and soil type affect the duration of bioremediation
- In situ or ex-situ bioremediation affects the duration of bioremediation
