What is an aerobic septic system?

If bleach is regularly poured into a septic system, it can upset the balance of bacteria.

An aerobic septic system is a septic system in which bacteria are stimulated to grow for the purpose of further breaking down the effluent from the septic system before it is released. These septic systems require less space and can be used when a conventional anaerobic septic does not fit or is not practical. They can also be used to overhaul or fix a conventional septic system that has started to malfunction. Numerous companies manufacture aerobic septic systems and can be installed by plumbing and septic professionals.

In general, care must be taken to ensure that the balance of microorganisms in the septic tank is healthy.

Initial processing in an aerobic septic system is similar to a conventional system, with wastewater flowing into a tank that allows solids to settle to the bottom while liquid flows into a secondary tank. In this tank, fans keep the air moving so that aerobic bacteria can thrive and process the waste water, which flows down another pipe. In some regions, effluent must be sterilized with a chemical, such as bleach, before being released, to kill microorganisms in the effluent.

Less space is needed with an aerobic septic system because the system processes wastewater very quickly thanks to the microorganisms doing the work. However, system operation and maintenance can be expensive. Electricity is required to operate the air blowers and agitator in the tank, and care must be taken to ensure that the balance of microorganisms in the tank is healthy, which means that people must be careful what they deposit in the system. septic; if they use bleach regularly, for example, it can destabilize bacteria.

In some regions, people can only install an aerobic septic system if they are willing to enter into a maintenance contract with a certified company. This requirement is a result of public safety concerns, because if the aerobic septic system is not properly maintained, it can result in the spread of disease from untreated wastewater. Companies that install these systems are often qualified to perform maintenance and may enter into a maintenance contract at the time of installation.

These systems are primarily designed for small-scale use, acting as a miniature water treatment plant for a single home, and are primarily used in rural areas. The resulting sterilized effluent can be used for ornamental gardening or landscaping, and should not be applied to food crops if any microorganisms have managed to pass through the entire system.
