What is aerobic treatment of sewage?
Aerobic treatment of wastewater is a biological process that uses oxygen to break down organic contaminants and other pollutants like nitrogen and phosphorous. Oxygen is continuously mixed into the wastewater or sewage by a mechanical aeration device, such as an air blower or compressor.

How does aerobic treatment work?
The aerobic treatment uses oxygen to break down the effluent and remove the different pollutants such as phosphorus and nitrogen. In this process, oxygen is required to form air. This air is forced via blower or compressor to mix with the wastewater. It converts the sludge into new biomass.
What are aerobic treatments?
Aerobic treatment is a biological wastewater treatment process that takes place in the presence of oxygen. Aerobic biomass converts organics in the wastewater into carbon dioxide and new biomass.
What you need to know about aerobic septic systems?
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.
How do you know when your aerobic septic tank is full?

What is aerobic process?
An aerobic process refers to a process that requires the presence of oxygen or air as opposed to an anaerobic process that does not require it. An example of an aerobic process is aerobic respiration. The biological cell conducts respiration in a process called cellular respiration.
What is an aerobic treatment unit in wastewater treatment?
Aerobic Treatment Unit. An aerobic treatment unit (ATU) consists of several processes that function together to provide a high quality effluent. These are gross solids (trash) removal, aeration, clarification, and sludge return. These processes are generally contained within separate chambers of a single tank.
How often should I perform maintenance on my aerobic treatment system?
