Aerobic treatment involves the provision of an oxygen-rich environment for organisms capable of reducing the organic portion of the waste into carbon dioxide and water.
Historically, preference for the use of septic tanks as primary treatment devices was prevalent compared with aerobic treatment. However, technological innovations in recent times have made individual aerobic treatment systems more efficient and affordable.
Aerobic systems, just like septic systems, utilize natural processes to treat wastewater. The difference between the two systems lies in the fact that the aerobic system requires a mechanism to inject and circulate oxygen within the treatment tank to achieve a more superior effluent quality, capable of being discharged either through subsurface or directly into the surface.
