Abstract

significant breakthrough and progress have been made in the study of the kinetics of microbial transformation in sewers under aerobic and under changing aerobic/anaerobic conditions. Fundamental knowledge on anoxic kinetics of wastewater is still lacking, so it is not now possible to apply an integrated approach to municipal wastewater treatment incorporating sewer networks as a bio-chemical reactor. This paper presents the results of studies on determining half saturation constants for nitrate, K_NO3, and nitrite, K_NO2, in raw wastewater. The average values of K_NO3 and K_NO2, determined from experiments conducted on 7 different wastewater samples were found to be 0.76 gNO₃.N/m³ and 0.33 gNO₂-N/m³ respectively.
