AEROBIC SEPTIC SYSTEM The use of residential aerobic septic systems has been fairly limited, in part, because of the widespread use of conventional septic systems, which are relatively inexpensive and easy to maintain. Conventional septic systems are the most common onsite wastewater treatment systems in rural areas.
The basic aerobic septic system, aka aerobic treatment unit (ATU), is a system that provides a suitable oxygen rich environment for organisms that can reduce the organic portion of the waste into carbon dioxide and water in the presence of oxygen.
Aerobic septic systems are similar to conventional septic systems in that they both use natural processes to treat wastewater. But unlike septic (anaerobic) treatment, the aerobic treatment process requires oxygen. Aerobic treatment units, therefore, use a mechanism to inject and circulate air inside the treatment tank.
Because aerobic septic systems use a higher rate process, they are able to achieve superior effluent quality. The effluent can be discharged directly to the surface.
