6.2.2.1. Aeration or oxygenating systems

• Aeration is always the first step when increasing carrying capacity over an open, lightly loaded system.
• Mechanical surface aerators, subsurface air bubblers and pure oxygen injection is the typical progression in terms of technology and complexity.
• All aerobic biofilters require oxygen to operate. If the biofilter does not provide its own oxygen, it will be limited to the oxygen carried in with the water.
