In the secondary treatment phase waste water is treated by means of bacterial breakdown of the dissolved biological waste.

In order to foster this bacterial break-down, the oxygen level of the water needs to be correct, not to high nor to low. Aeration is the process by which the area of contact between water and air is increased, either by natural or mechanicalmeans, resulting in air being suspended in water.
