As stated in the main glossary, aerobic wastewater treatment is oxygen dependent wastewater treatment, requiring the presence of oxygen to facilitate aerobic bacterial breakdown of wastewater sludge, such as an extended aeration packaged plant, an oxidation ditch or even simply wastewater treatment ponds.
Aerobic wastewater treatment, the treating of wastewater where oxygen is present, is also a type of biological wastewater treatment since the process is typically a biological one, not chemical.
Oxygen is required for the aerobic bacteriological process, and is usually added through aeration of some sort, though not always. The aerobic bacteria convert organic solids to co2.
Aerobic wastewater treatment is generally considered a much faster process then anaerobic processes. Used when wastewater is high in soluble organics and a speedier process is desired, since the sludge usually breaks down much faster with a boosted aerobic process, the cost is also higher due to the need for aeration of some sort. Aerobic wastewater treatment involves aerobic bacteria as opposed to anaerobic bacteria such as are typical in septic tank systems.
Aerobic wastewater treatment is simply the rapid biological breakdown of soluble organics by aerobic bacteria. Really pretty simple.
