There are many methods to treat wastewater: mechanical, physicochemical or biological methods. Among them, the biological method is considered an effective method, low cost, easy to operate and environmentally friendly.

Wastewater treatment by aerobic biological method is based on the principle of using microorganisms to treat organic substances and some inorganic pollutants in wastewater. Water creates products that are not harmful to the environment.
Depending on the microorganism used, there are different treatment methods. These can follow: aerobic, anoxic and anaerobic treatment methods. Aerobic biological method has the advantage of fast, effective and simple treatment. Therefore, it has been chosen to be used a lot in wastewater treatment projects.

What is aerobic biological method?
Concept of aerobic biological method
Aerobic biological method is a method that uses aerobic microorganisms to treat pollutants in water under the condition that oxygen is involved.
Commonly used microorganisms are: Actinomyces, Bacillus, Bacterium, Micrococus,…
Factors affecting aerobic treatment
For wastewater treatment by aerobic biological methods to take place, the following factors need to be paid attention to:
- Ensure continuous oxygen supply for the microorganism
- Amount of nutritional elements necessary for biochemical processes to occur
- Allowable concentration of organic substances
- Limit the concentration of toxic substances that affect microorganisms
Aerobic treatment processes can be under natural and artificial conditions. In artificial treatment works, due to optimal conditions, the processing process has much higher speed and efficiency.
Depending on the state of existence of microorganisms, they are divided into two types. That is treatment with suspended microorganisms and adherent microorganisms.
