Nitrification Principle / Field Trials of Nitrification Efficiency
All the 6 reactors that constitute the PBBR exhibited ammonia consumption of ˜ 1ppm/hr (Fig 1 (a), (b) & (c)), and the rate of consumption increased with the strength of the substrate.
All the 6 reactors that constitute the PBBR exhibited ammonia consumption of ˜ 1ppm/hr (Fig 2 (a), (b) & (c)), and the rate of consumption increased with the strength of the substrate .
The increase in the substrate concentration resulted in the increased substrate consumption.

Fig. 3. Volumetric TAN removal rates by the reactor with flow rate.
The maximum volumetric TAN removal was obtained at its maximum turn over of 2500L/hr was 18 g NH4+-N per day with a HRT of 48 seconds.
