Nitrification/Denitrification

      This biotechnology process is suitable for wastewater with high TKN such as in frozen food, meat processing, canned food. There are comprises of 2 steps which shown in the following process.
Nitrification process 

                                  Nitrifying bacteria
2NH4+ + 5O2 ---------------------------------> 2NO3- + 4H2
Denitrification process

                                Denitrifying bacteria
NO3-+ 5COD ---------------------------------> N2 + CO2
         From denitrification process less oxygen is required because bacteria use oxygen from nitrate to use in carbon oxidation.Thus the operating cost for N/DN is lower than the conventional activated sludge process.
