- •
Advection-dispersion-sorption-biodegradation transport model was considered.
- •
The retarded transport observed was in the order NH4+ > acetate > NO3−.
- •
Microbial assimilation and biodegradation were the major nitrogen removal mechanisms.
- •
The numerical model well predicted the transport of nitrogen compounds.
