Assume COD entering an anaerobic digester can be modeled as2C3H5O3- = C3H5O2- + C2H3O2- + CO2 + H2 (Balanced reaction

Next, assume that methane in the reactor results from twopathways: aceticlastic methanogenesis and hydrogenotrophicmethanogenesis. If we assume that all necessary carbon and hydrogenfor methane production comes only from fermentation of lactate; howmuch methane (in mg/L) can be produced assuming 25,000mg/L CODentering the anaerobic digester, with all of it beingfermented?
