An extended ,aeration, sludge requires 20 days, but a contact stabilization sludge requires longer. After ,aeration, for the required time, the aerators are turned off and the sludge is allowed to settle. The liquid on top (supernatant) is returned to the ,aeration, basin of the waste- water treatment plant.
