'''An Aerated Pond is a large, outdoor, mixed aerobic xxxxxx reactor.Mechanical aerators provide oxygen and keep the aerobic organisms suspended andmixed with the water to achieve a high rate of organic degradation and nutrient removal.'''
Increased mixing and aeration from the mechanical units means that the ponds can be deeper and can tolerate much higher organic loads than a maturation pond. The increased aeration allows for increased degradation and increased pathogen removal. As well, because oxygen is introduced by the mechanical units and not by light-driven photosynthesis, the ponds can function in more northern climates. Influent should be screened and pre-treated to remove garbage and coarse particles that could interfere with the aerators. Because the aeration units mix the pond, a subsequent settling tank is required to separate the effluent from the solids.
