The autotrophic oxidation of ammonia to nitrate is an important reaction in wastewater engineering as it is the first step in the biological removal of nitrogen from wastewater. Determine the balanced equation for the ammonia to nitrate reaction (nitrification) using the fs max value of 0.10 and realizing that ammonia is available for use in cell synthesis. Determine the amount of oxygen required to oxidize 30 mg/L of ammonia and determine the biomass generated during this nitrification process.
