An aerated pond is a large, mixed aerobic reactor similar to facultative ponds in systems, with the difference that natural oxygenation is enhanced. Mechanical aerators provide oxygen and keep the aerobic organisms suspended and mixed with water to achieve a high rate of organic degradation. As natural oxygenation is enhanced, ponds can be deeper (thus smaller in surface) and are suited also for colder climates compared. The effluent of aerated ponds may be reused or used for recharge, but settled sludge requires a further treatment or correct disposal.
