Design and Components
Aerobic treatment units (ATUs) are designed to increase the bacterial activity in the treatment tank by injecting oxygen. They consist of multiple chambers, including a pretreatment chamber, an aeration chamber, and a clarification chamber. These chambers work together to provide enhanced treatment and reduce the amount of solids in the effluent.
How they work
ATUs work by introducing oxygen into the treatment tank, which promotes the growth of aerobic bacteria. These bacteria break down organic matter more efficiently than the anaerobic bacteria found in conventional septic systems. The treated effluent is then discharged to a drainfield or a disinfection unit before being released into the environment.
Pros and cons
One of the significant advantages of ATUs is their ability to provide superior treatment compared to conventional systems. They can reduce the levels of nitrogen and phosphorus in the effluent, making them suitable for sites with strict water quality requirements or sensitive ecosystems. However, they may have higher energy consumption and maintenance requirements compared to conventional systems.
Cost to purchase and maintain
The cost of purchasing and installing an ATU will vary depending on factors such as system size, technology, and labor costs, but is more expensive than other systems. Maintenance costs may also be higher due to the need for regular inspection, monitoring, and potential replacement of components.
