The high rate moving bed biofilm reactor (MBBR) processes were designed for wastewater treatment to meet the past effluent discharge norms of biological oxygen demand (BOD) <50 mg/l. However, they are incapable of meeting current effluent discharge norms which consist of BOD <10 mg/l and total nitrogen <10 mg/l. This study analyses the effect and variation of organic loading rate from 1.21 kg to 4.59 kg chemical oxygen demand (COD)/(m3 day) and surface loading rate from 4.9 g to 24 g COD/(m2 day) on a high rate MBBR performance. The results of COD reduction (CODred) and subsequent ammoniacal nitrogen reduction (NH3–Nred) were in the range of 65.4% to 87.8% and 11.8% to 47.2% respectively. The projected graphical optimization defines the design parameters for MBBR and also predicts CODred and subsequent NH3–Nred. By understanding this subsequent NH3–Nred in the MBBR system, future designs for engineering technologies will be aided.

Abstract


The high rate moving bed biofilm reactor (MBBR) processes were designed for wastewater treatment to meet the past effluent discharge norms of biological oxygen demand (BOD) <50 mg/l. However, they are incapable of meeting current effluent discharge norms which consist of BOD <10 mg/l and total nitrogen <10 mg/l. This study analyses the effect and variation of organic loading rate from 1.21 kg to 4.59 kg chemical oxygen demand (COD)/(m3 day) and surface loading rate from 4.9 g to 24 g COD/(m2 day) on a high rate MBBR performance. The results of COD reduction (CODred) and subsequent ammoniacal nitrogen reduction (NH3–Nred) were in the range of 65.4% to 87.8% and 11.8% to 47.2% respectively. The projected graphical optimization defines the design parameters for MBBR and also predicts CODred and subsequent NH3–Nred. By understanding this subsequent NH3–Nred in the MBBR system, future designs for engineering technologies will be aided.
