Abstract

Development of nitrification biomass that is growing attached on carried material was examined by
measuring its ammonium or nitrit oxidation rates. Porous ceramic rings (36 pieces) were put into the
fixed bed reactor (FBR ). The fixed bed reactor that was operated continuously for more than 500 day
was continued to be operated at a HRT of 1 day, a DO of above 5 mg L
-1
and pH of 8. Ammonia
concentration in the feeding was 50 mg NH
4
+
-N

L
-1
. At days 1, 5, 12, 20, 33 and 50, six porous
ceramic rings were taken out and then ammonia and nitrite removal rate by biofilm in the ceramic rings
was separately measured. The measurement of rates was done in small cylindrical glass reactors with
initial concentration of ammonia and nitrite was 10 mg N L
-1
. Until 50 days of incubation AORs were
always higher than NORs. Additionally, ammonia oxidizers attach or grow faster in the porous ceramic
material than nitrite oxidizers.
