(a) Write the balanced chemical reaction for the following nitrogen cycle reactions:
(i) nitrification of ammonium to nitrite using molecular oxygen
(ii) nitrification of nitrite to nitrate using molecular oxygen
(iii) denitrification of nitrate to N2 using succinic acid (see Figure 6.10 for structure) as the carbon/energy source
(b) If a wastewater effluent has an ammonium concentration of 12 mg/L as N, what is its nitrogenous BOD; that is, how much O2 (in mg/L) would be required to oxidize the ammonium to nitrate?
16.5. (a) Write the balanced chemical reaction for the following nitrogen cycle reactions: (i) nitrification of ammonium to nitrite using molecular oxygen (ii) nitrification of nitrite to nitrate using molecular oxygen (iii) denitrification of nitrate to N2 using succinic acid (see Figure 6.10 for structure) as the carbon/energy source NUTRIENT CYCLES AND NITROGEN AND PHOSPHORUS 631 on of 12 mg/L as N. what is its nitrogenous BOD; that is, how much O2 (in mg/L) would be required to oxidize the ammonium to nitrate?
