Key components of a typical oxidation ditch
include a screening device, an influent distributor
(with some systems), a basin or channel, aeration
devices (mechanical aerators, jet mixers, or
diffusers, depending on the manufacturer), a
settling tank or final clarifier (with some systems),
and an RAS system (with some systems).
Typically, the basin and the clarifier are
individually sized to meet the specific requirements
of each facility. These components are often built
to share a common wall in order to reduce costs and
save space (Lakeside, 1999).
