. A wastewater from a fermentation facility contains 1,200 mg/L ethanol and 800 mg/L acetic acid. A continuously stirred tank reactor (CSTR) is used to convert the wastewater into biogas at 35oC. The flow rate of the wastewater is 1,000 m3 /d. The target conversion efficiency for both acetic acid and ethanol is 80%. What are the production rates of CH4 and CO2 in the CSTR?
