Also, some nitrification will take place due to continues flush out of nitrifying biomass from the trickling filters, which then accumulates in the activated sludge and will cause some nitrification in the aerated zones of the aeration tanks.
Thus, the bio-filter was proven to be efficient enough to provide appropriate surface area for nitrifying bacteria to colonize and populate.
by pelagic nitrifying bacteria, hence explaining their observation of elevated N[O.
The reason why there still some microbial activity was inhibited at the height of 10cm was that organic matter concentration of wastewater quality in experiment was lower so that there was phenomenon of a certain nitrifying bacteria existing of inflow and there was not condition of heterotrophic bacteria and autotrophic bacteria stratifying; while as the increasing of the height of the sampling connection, the inhibition ratio of hydrolyzing urea increased gradually.
High concentrations of ammonium ion in the well waters had resulted in the colonization of the distribution system with nitrifying bacteria which mediated the conversion of ammonium to nitrite ion.

The nitrifying process in a microorganism takes place in two phases: 1) oxidation of ammonium to nitrite, and 2) oxidation of the nitrite to nitrate.
