A beef production facility produces 750 m³/d of wastewater. The wastewater contains 16,000 mg/L tCOD and is made up of primarily organic content that can be represented as C₃₇H₂₉O₅N (based on elemental analysis). The equations associated with aerobic and anaerobic heterotrophic degradation of this influent composition are respectively:

C₃₇H₂₉O₅N + 16 O₂ + 4 NH₄⁺ + 4 HCO₃^- 5 C₅H₇O₂N + 16 CO₂ + 7 H₂O

4 C₃₇H₂₉O₅N + 103 H₂O 3 C₅H₇O₂N + 75 CH₄ + 57 CO₂ + NH₄⁺ + HCO₃^-
