Abstract
Systems and methods for producing ammonium nitrate are disclosed herein. Exemplary systems can comprise a bioreactor positioned to receive a feed including ammonia. The bioreactor can hold a liquid solution including (i) an ammonia oxidizing bacteria (AOB) and (ii) a nitrite oxidizing bacteria (NOB). The AOB can facilitate oxidation of the ammonia to produce a nitrite at a nitritation rate and the NOB can facilitate oxidation of the nitrite at a nitratation rate. Thus, the bioreactor can produce a mixed liquor comprising a nitrate biologically. The system can further comprise a filter positioned to receive the mixed liquor and produce a permeate and a sludge. A sensor can measure the concentration of the liquid solution of the bioreactor, and a controller coupled to the sensor can regulate the mass flow of nitrogen and/or phosphorus of the bioreactor feed based on the measured concentration of the liquid solution.
