HMBR combines classical organic carbon depollution with simultaneous nitrification
In the present study, the practicability of the long-run treatment of wastewater containing high concentration ammonia nitrogen via the utilization of aerobic granular sludge is determined via granular sludge cultured through nitrification
For example, a urine nitrification
reactor is currently in operation in Nairobi/Kenya to treat urine collected by the organisation Sanergy.
process decreased from 70% in first load to 45% in the second load by decreasing the HRT.
The stabilization reactor was a unique unit with different compartments that could be described as follows: i) SR: an aerated zone of suspended growth with a high presence of organic carbon; ii) SR an anoxic zone which favored denitrification; iii) SR an attached-suspended growth zone which favored nitrification
and denitrification; and finally, iv) SR, an additional aerated zone of suspended growth with a high ammonia concentrations measured as total ammonia nitrogen (TAN) for favored nitrification
Since the air-diffuser position resulted in the formation of aerobic or anoxic zone, the performance of nitrogen removal through SND might be compared to the separated reactions of nitrification
These compounds from root exudates of potentially allelopathic plant species inhibit the activity of AMO (ammonia mono- oxygenase) and HAO (hydroxylamine oxidoreductase), the two bacterial enzymes responsible for catalysis of nitrification
reactions in soil (Subbarao et al., 2008).
medium consisted of the following components: 0.382g/L NH4Cl 1.0g/L CH3CH2ONa 0.05g/L MgSO47H2O 0.2g/L K2HPO4 0.12g/L NaCl 0.01g/L MnSO4 and 0.01g/L FeSO4.
So by controlling high rates of soil nitrification
process nitrogen use efficiency (NUE) can be improved.
Dissolved oxygen for nitrification
is achieved through the use of high-volume blowers and an underwater aeration grid at the bottom of the cell.

Soil and litter samples were analyzed for their capacities (i.e., potential rates) to express nitrification
and denitrification (both processes being directly involved in the balance between N[H.sub.4.sup.+] and N[O.sub.3.sup.-]).
