Answer:
An aerobic treatment system (ATS), often called (incorrectly) an aerobic septic system, is a small scale sewage treatment system similar to a septic tank system, but which uses an aerobic process for digestion rather than just the anaerobic process used in septic systems. These systems are commonly found in rural areas where public sewers are not available, and may be used for a single residence or for a small group of homes

Answer:
Aerobic processes use bacteria that require oxygen, so air is circulated throughout the treatment tank and aerobic bacteria breaks down the waste in the wastewater. Some systems use a pre-treatment stage before the main treatment, as well as sanitising prior to release into the environment.
