Abstract:

The traditional nitrogen removal processes of nitrification and subsequent denitrification face many challenges when applied to high nitrogen (∼200 mg/L total Kjeldahl nitrogen, TKN) wastestreams such as swine wastewater. Ammonium oxidation is accompanied by a drop in pH due to the loss of alkalinity, which may inhibit nitrifying bacteria. This pH drop is not significant for municipal wastewater because of the low ammonium levels, but is significant for high ammonium wastes. In addition, the low BOD/N (biochemical oxygen demand/nitrogen) ratio can cause poor nitrogen removal efficiencies (Bortone et al. 1994), and the addition of supplemental organic matter such as methanol or acetate in the denitrification step can make the process costly.
