What Are Biological Aerobic Wastewater Treatments?

Wastewater treatment plants were not always necessary. In the past, a naturally occurring purification process would occur where bacteria and other organisms found in waterways would break down sewage into harmless byproducts. However, these microorganisms could not successfully manage purifying the wastewater for an increasing population and production of sewage.

Therefore wastewater is now being sent to wastewater treatment plants to alleviate the burden on these naturally occurring bacteria and microorganisms.


A biological aerobic treatment is a type of wastewater treatment that takes place in the presence of oxygen. These types of wastewater treatments tend to work faster and result in cleaner water than other types of wastewater treatments. The most popular type of biological aerobic wastewater treatment is the activated sludge process.


During an activated sludge process the wastewater moves into an aeration tank that is pumped full of oxygen so that microbial growth will increase and speed up the decomposition of the organic matter that is still present in the water. Once this process is complete, the wastewater is transferred into a secondary clarifier.

Any waste or sludge that remains will start to separate and leave clean, treated water behind. The remaining sludge can be used in the following ways:

  • It can be converted into methane and carbon dioxide and used for heat or electricity.

  • It can be dried and composted or sent to a landfill.

Sludge management is one of the biggest and most expensive issues within wastewater treatment plants. Due to the high costs of sludge management and the issues with locating a disposal site, new ways to reduce sludge production are needed.


Luckily, here at In-Pipe Technology, we have an approach that can reduce the costs of managing sludge by as much as 30%. Our game-changing solution incorporates the most adaptable and efficient bacteria around. And we tailor our process to fit each type or style of collection system.
