Question

Nitrification is an aerobic, autotrophic process in which ammonium/ammonia nitrogen is oxidized to nitrate. The following overall stoichiometric equation, including synthesis of biomass (i.e., C5H7O2N), has been reported:

NH4+ + 1.863 O2 + 0.098 CO2 = 0.98 NO3- + 0.941 H2O + 1.98 H+ + 0.0196 C5H7O2N

Calculate:

a) The quantity (g) of alkalinity as CaCO3 consumed per gram of ammonium nitrogen (i.e., NH4+-N) oxidized.

b) The quantity (g) of oxygen required per gram of NH4+-N oxidized.

Answer 1

This is a stoichiometric problem.

The question isn't typed properly. But, This is the best possible solution.

I hope it will be clear to you.
