Anaerobic upflow (ANFLOW) bioreactors which use fixed films of microorganisms have been considered for alternative wastewater treatment systems. The advantages of this system are presented. The presence of ammonia in the effluent results in a high nitrogenous oxygen demand to receiving waters and is toxic to certain biota at low concentrations. The presence of ammonia in the effluents of wastewater treatment systems must be regulated. Effluent ammonia and ammonia production rates were monitored within the ANFLOW bioreactor as synthetic feed compositions and flow rates were varied. Correlations between influence organic nitrogen loadings and effluent ammonia concentrations were sought. Subsequent ammonia removal methods were proposed. It was demonstrated that ammonia can be easily nitrified with an aerobic upflow biological filter with only 5% of the volume of the ANFLOW bioreactor. Methane production was also measured.
