Difference Between Aerobic and Anaerobic Digestion
Aerobic digestion is the process of generating an oxygenated atmosphere in which microorganisms organically break down food waste over a short period of time into water that may be disposed using existing drainage systems.
Aspect |
Aerobic Digestion |
Anaerobic Digestion |
---|---|---|
Oxygen Requirement |
Oxygen (O2) is necessary |
oxygen (O2) is not necessary |
Microbial Activity |
Performed by aerobic microorganisms, such as fungus and bacteria |
Conducted by microbes that don’t require oxygen, like as bacteria and archaea. |
End Products |
H2O and CO2 |
CO2 and CH4 |
Temperature Range |
35 to 45 °C |
30-40°C |
Reaction Rate |
Fast |
Slow |
Nutrient Retention |
Increased nutritional intake and retention requirements |
Generally more effective at retaining nutrients |
Energy Production |
Decrease amount of ATP is produced than during anaerobic digestion. |
Increases the amount of energy (biogas) produced per substrate unit. |
Application |
Often employed in wastewater treatment, organic waste aerobic digestion, and composting |
Frequently employed in the anaerobic digestion of organic wastes, wastewater treatment, and biogas generating processes |
Anaerobic Digestion
Anaerobic Digestion takes place in the absence of oxygen by the microorganisms. It is a natural recycling process. These microbes feed on biodegradable materials such as food waste or manure, breaking them into simpler molecules. This breakdown produces gases such as methane, which can be used as a fuel source. In this article, we will learn about anaerobic digestion, its process, wastewater treatment, digesters, etc.
