In this research the continuously up-flow pilot scale Moving Bed Biofilm Reactor (MBBR) which was consists of combined cylindrical anoxic/aerobic MBBR in nested form with anoxic/aerobic volume ratio equal to 0.16 under fully nitrification-denitrification process were used to treated 4 m34+-N, TN and TP, respectively, while the average Dissolved Oxygen concentration (DO) in aerobic and anoxic MBBRs were 4.49 and 0.16 mg/L, respectively.
Key words: Ammonium nitrogen, anoxic, attached biomass, autotrophic, biofilm, biological treatment, carrier, conventional activated sludge process, heterotrophic, nitrate, nitrite, nitrogen, phosphorus, sequencing batch moving bed biofilm reactor, suspended biomass
