The objective of the work was to study the effect of C/N ratio and type of aeration on nitrification rates of activated sludge by advanced wastewater treatment process. The activated sludge from 26 wastewater treatment plants were collected and grouped through A-H depending upon the type of industry and the C/N ratio. The experiment was carried out in lab-scale (20 liters) and pilot plant scale (8000 liters). For the case of pilot plant scale, two type of aeration were studied namely side aeration and overall aeration. The specific nitrification rate (SNR) was calculated and it was correlated with the C/N ratio and the aeration type. No inverse relation between the C/N ratio and the SNR had been established. This result disagree with the earlier study. The SNR for overall aeration was more compared with side aeration for the same dissolved oxygen level in both type of aeration. The difference between SNR of two different type of aeration was about 8.8%.
