A cheese 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^-

(1) If it is required to achieve 92% or better COD removal, assuming a K_d of 0.6 d^-1 (for degradation of COD), estimate the minimum CSTR-based reactor volume required to treat the wastewater produced at this facility
