Abstract:
:Kinetics of nitrification and denitrification of synthetic wastewater was investigated by using two reactors in series. An activated sludge unit was used for nitrification followed by a downflow biofilter for denitrification. Glucose solution was fed to the denitrification column to supply carbon source. Reactors were operated at different operating conditions and data were collected for determination of kinetic constants. Experimental data indicated that nitrification and denitrification kinetics followed Monod kinetics. By using the experimental data, kinetic constants for nitrification were determined as k = 1.15 d(-1), K(N) = 5.14 mg/l, Y = 0.34 mgX/mgN and b = -0.021 d(-1). Similarly, kinetic constants for denitrification were determined as k = 0.23 d(-1) and K(DN) = 0.27 mg/l. Rates of nitrification and denitrification increased with increasing nitrogen loading rate.
