Abstract

In this study, it was investigated the effect intermittent aeration and step-feed on nitrogen removal
by providing anoxic-aerobic, anoxic-aerobic-anoxic-aerobic and step-feed anoxic-aerobic-anoxicaerobic working conditions. Chemical oxygen demand (COD) removal efficiency was the same in
all three working conditions and was found to be 91%. The NH4
+
-N removal efficiency is almost
the same. The NH4
+
-N removal efficiencies in the W1, W2 and W3 are 92%, 93% and 95%,
respectively. Total inorganic nitrogen (TIN) removal efficiency increased by 4% when intermittent
aeration was applied. Increasing the efficiency of TIN removal by 24% was achieved by applying
the step-feed intermittent aeration. Experimental results show that the effect of intermittent aeration
on TIN removal was limited and that TIN removal performance with step-feed intermittent aeration
was significantly increased.
