Just as in the case of conventional (or standard) systems, an aerobic septic system uses natural processes to treat wastewater.
How does aerobic septic work?
As mentioned, aerobic septic systems differ from conventional systems because the aerobic treatment process requires air to be injected and circulated inside the treatment tank. Hence, your aerobic septic system is made up of a greater number of parts than a conventional system, including electrical components and extra tanks. Specifically, your system will have a trash tank (got one), an aerobic treatment unit (tick) and a pump tank (yep, there it is). An air compressor infuses the treatment unit with air through diffusers in the tank and the cycle begins.
Why are aerobic septic systems more expensive than standard systems?
Aerobic septic systems are more complex than standard systems because of this they are also more costly. The value lies in the speed and the advanced level of treatment that you can expect from an aerobic septic system.

Overview
An aerobic treatment system (ATS), often called 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.
Process
The ATS process generally consists of the following phases:
• Pre-treatment stage to remove large solids and other undesirable substances.
• Aeration stage, where aerobic bacteria digest biological wastes.
• Settling stage allows undigested solids to settle. This forms a sludge that must be periodically removed from the system.
Types of aerobic treatment systems
Small scale aerobic systems generally use one of two designs, fixed-film systems, or continuous flow, suspended growth aerobic systems (CFSGAS). The pre-treatment and effluent handling are similar for both types of systems, and the difference lies in the aeration stage.
Fixed film systems use a porous medium which provides a bed to support the biomass film that digests the waste material in the wastewater. Designs for fixed film systems vary widely, but fal…
