What is an Aerobic Septic System?
Aerobic septic systems are used in situations where standard septic systems are not a viable option. In many cases, they are used to replace failing septic systems. Aerobic systems are similar to septic systems in that they both use natural processes to treat wastewater. But unlike septic (anaerobic) treatment, the aerobic treatment process requires
oxygen. There are two types of bacteria, anaerobic and aerobic.
Aerobic bacteria work much faster than anaerobic bacteria, which means they process septic tank waste more quickly. Aerobic treatment units use a mechanism to inject and circulate air inside the treatment tank, which accelerates or speeds up the treatment process. This mechanism requires electricity to operate. For this reason, aerobic systems cost more to operate and need more routine maintenance than most septic systems.
However, when properly operated and maintained, aerobic systems can provide a high quality wastewater treatment alternative to septic systems. They can also be used in some cases by owners of wooded lots, who don”t want to clear enough land to install a traditional septic tank and drainfield.
