What does the abbreviation AOB stand for in wastewater treatment?

The abbreviation AOB stands for Ammonium Oxidizing Bacteria. These bacteria play a crucial role in the nitrogen cycle, particularly in the process of nitrification during wastewater treatment. In this process, AOB convert ammonium (NH4+) into nitrite (NO2-), which is a vital step in reducing ammonia levels in wastewater.

Understanding the role of Ammonium Oxidizing Bacteria is essential in wastewater treatment because high levels of ammonia can be toxic to aquatic life, and effective treatment processes help ensure that water released back into the environment is safe and environmentally friendly. The presence and activity of these bacteria are often monitored to optimize wastewater treatment processes, making knowledge of their function key for those working in this field.
