In
this study, the effect of aerobic
and anoxic phase durations on simultaneous
organic carbon and nitrogen removal was studied in three sequencing batch
reactor (SBR). The higher organic matter and nitrogen removal was obtained in
reactor (AKR 2) to be aerobic phase duration of 4 hours and anoxic phase
duration of 2 hours. In this reactor (AKR 2), the removal efficiencies of COD, NH4+-N,
NOX (NO2+NO3) were about 90 %, 92 % and 64 %,
respectively.
