“…During the hydrogen production, the COD removals were only 42% at 2 days HRT. The reason could be that under anaerobic conditions, the mineralization of organic matters is incomplete unless methane was produced [40]. The COD removal efficiency in the first stage was little higher compared to other previous reports [7,30].…”

“…In the fact, vinasse can contain TS more than that [10]. The COD content of vinasse is more than 100,000 mg/L [12]. Whereas, Budiyono et al [11] reported that vinasse contains COD content of 299,250 mg/L.…”

“…Vlyssides et al [20] stated that high concentration of P and N nutrients cause eutrophication in water bodies. The temperature of fresh vinasse that is out from distillation unit is 65 -105 o C [1,12]. If vinasse is disposed to bodies water, not cooled before, temperature of bodies water can increase.…”

The two‐stage process of combined hydrogen and methane production with the recirculation of digestate sludge using palm oil mill effluent as substrate was investigated. During the first stage, an up‐flow anaerobic sludge blanket reactor (UASB) was operated at thermophilic conditions [hydraulic retention time (HRT)−2 days, organic loading rate −75 gCOD L−1d−1] for hydrogen production. The operation performance at short HRT and low pH was useful to separate the acidogenesis from methanogenesis. The effluents from UASB reactor containing mainly acetate and butyrate were fed into a continuous stirred tank reactor (CSTR) for methane production under the mesophilic temperature at two different HRTs (5 and 3 days). Both UASB and CSTR reactors were operated for 120 days continuously and a stable production of the hydrogen and methane was obtained simultaneously. The total hydrogen and methane yields obtained were 215 L H2 kgCOD−1 and 320 L CH4 kgCOD−1, respectively with the total COD removal efficiency of 94% in the two stage process. © 2017 American Institute of Chemical Engineers Environ Prog, 36: 895–902, 2017
