Why does ammonium concentration inhibit the growth of NOB, although it is not used as their energy source?

Ammonium is neither consumed nor produced in nitrite oxidation, how does ammonium concentration suppress NOB and why?

Why is the yield (cell production/ammonium consumption) higher in the Annamox than in nitrification?

Both Annamox bacteria and nitrifiers are slow growers and they both grow on ammonium as their energy source, nitrification is aerobic and annamox is anaerobic , shouldn't the yield in...

Can we consider only the kinetics of the nitrite oxidizing bacteria when modelling nitrification pathway?

Since the nitrite produced during the partial nitrification is virtually immediately further nitrified to nitrate. And the rate of conversion of ammonia to nitrite by ammonia oxidizing bacteria is...

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...
