Aerobic bacteria decompose various organic substances in wastewater into carbon dioxide, water and various salts through aerobic respiration. When oxygen becomes scarce, gases such as methane, phosphine and hydrogen sulfide are generated due to the action of anaerobic bacteria, resulting in odor, and a large space is required for a long period of time to treat large amounts of wastewater due to a slow reaction.

The conventional extended aeration process has a simple system,
but consumes high energy, because 66.6% of the energy consumed is used to dissolve other gases in water.
