what happens to the ammonia in chloroamines after disinfection?

what happens to the ammonia in chloroamines after disinfection?

(OP)
I understand that there are some benifits in using chloroamines for disinfecting wastewater.  I know that during disinfection, the chlorine is converted to chloride.  I also understand that during break point chlorination the ammonia is converted to nitrates and then to nitrogen gas.  What I wonder is what happens to the ammonia during the disinfection reaction before break point chlorination is reached.  Is it converted to nitrate?  I would very much appreciate your comments and references on this subject.  Thanks.

RE: what happens to the ammonia in chloroamines after disinfection?

Monochloramine is persistent in the environment. It hydrolyses slowly in aqueous solutions.

Two groups of bacteria (ammonia- and nitrite-oxidizing bacteria) commonly found in terrestrial and aquatic environments
eventually oxidize ammonia into nitrite and nitrate sequentially.

Thanks bimr for your answer and reference.  I thought that monochloroamine was toxic to bacteria and hence its disinfecting power !  ...but if starved, they'll eat anything!  Thanks again.
