“…CW was stored in a refrigerator at 4 • C. Since the pH of the CW was low, before feeding into the reactor, the pH was adjusted to 7.0 with a solution of 1 M NaOH. CW was not sterilized before being fed into the reactor, since it was previously shown that for stable formation of hydrogen, it is sufficient to ensure the storage of whey at 4 • C [23].…”

This article presents the results of the start-up of continuous production of biohydrogen from cheese whey (CW) in an anaerobic filter (AF) and anaerobic fluidized bed (AFB) with a polyurethane carrier. Heat and acid pretreatments were used for the inactivation of hydrogen-scavengers in the inoculum (mesophilic and thermophilic anaerobic sludge). Acid pretreatment was effective for thermophilic anaerobic sludge to suppress methanogenic activity, and heat treatment was effective for mesophilic anaerobic sludge. Maximum specific yields of hydrogen, namely 178 mL/g chemical oxygen demand (COD) and 149 mL/g COD for AFB and AF, respectively, were obtained at the hydraulic retention time (HRT) of 4.5 days and organic load rate (OLR) of 6.61 kg COD/(m3 day). At the same time, the maximum hydrogen production rates of 1.28 and 1.9 NL/(L day) for AF and AFB, respectively, were obtained at the HRT of 2.02 days and OLR of 14.88 kg COD/(m3 day). At the phylum level, the dominant taxa were Firmicutes (65% in AF and 60% in AFB), and at the genus level, Lactobacillus (40% in AF and 43% in AFB) and Bifidobacterium (24% in AF and 30% in AFB).

“…(ii) the filling time or feeding strategy (Albanez et al, 2009;Oliveira et al, 2010); and (iii) the organic load (Massé and Masse, 2000;Damasceno et al, 2007;Friedl et al, 2009;Carvalhinha et al, 2010). Currently, in the literature, there is an increase in the potential application of batch and fed-batch reactors to generate bioenergy (methane and hydrogen) in a broad context in which the wastewater should be treated just as raw material and not as a process waste, with the aim of making it possible to obtain energy from the methane/hydrogen generated (Yang et al, 2008;Bezerra et al, 2011;Manssouri et al, 2013;Bravo et al, 2015;Lovato et al, 2012;Lima et al, 2015).…”

This work studied the feasibility of biohydrogen production by co-digestion of vinasse/molasses in an AnSBBR operated with mechanical stirring (30°C and 200 rpm). Hydrogen production by co-digestion of vinasse/ sucrose was also studied to verify the performance of the process with a known co-substrate with easy degradation. The effects of influent composition (vinasse/sucrose and vinasse/molasses), influent concentration (3000 and 4000 mgCOD.L -1 ) and cycle time (3 and 4 h) on performance indicators were evaluated using stability, organic matter removal efficiency, molar hydrogen yield, productivity and biogas composition. The condition with vinasse/molasses in the influent that showed the best results was obtained with a 3-hour cycle time, influent concentration of 3000 mgCOD.L -1 and composition of 33% vinasse and 67% molasses. The molar productivity in this condition was 3.8 molH 2 .m -3 .d -1 with a hydrogen molar fraction of 16% (and a methane molar fraction of 14%). A first order kinetic model was fitted efficiently to the best conditions.

“…Portanto, o reator AnSBBR com biomassa imobilizada operado em batelada e condição termofílica se mostrou uma configuração indicada para o tratamento da vinhaça. Na literatura atual, é cada vez mais comum a utilização desta configuração de reator na produção de metano ou hidrogênio pela viabilização da produção de bioenergia gerada a partir do tratamento de diversas águas residuárias, como vinhaça, soro, esgoto doméstico, efluente da produção de biodiesel e efluentes industriais (BEZERRA et al, 2009(BEZERRA et al, e 2011OLIVEIRA et al, 2009;LOVATO et al, 2012;ALBANEZ et al, 2016;LIMA et al, 2016).…”

The thermophilic anaerobic digestion of wastewater that are generated at high temperatures appers as an option for the environmental pollution control and bioenergy production. Thus, this study investigate a anaerobic reactor containing immobilized biomass and mechanical stirrer operate in sequential batch or feed batch treating vinasse-based wastewater for methane production. It was analyzed the effects on reactor performance of increasing the applied volumetric organic load (AVOL) and modifying the feeding strategy. The total volume of liquid was 2,3 L, in which 1,3 L of residual volume and 1,0 L of wastewater to be treated per cycle, keeping constant the temperature (55 ºCthermophilic range), the cycle length (8 hours) and the stirred velocity (100 rpm). At first it was realizes the biomass adaption, then it was analyzed the applied volumetric organic load (6,5-25,9 gDQO.L-1 .d-1) increasing the influent concentration and after the feeding strategy was modified. In the AVOL increasing were achieved higher molar productivity of methane (304 molCH4.m-3 .d-1) and volumetric productivity (6828 mL-CNTP CH4.L-1 .d-1) at AVOL of 25,9 gDQO.L-1 .d-1 , and molar yield of methane per organic matter removed close to the theoretical value (15,6 mmolCH4.gDQO-1) and removal efficiency of organic matter in terms of DQO between 75-80% for all conditions above AVOL of 14 gDQO.L-1 .d-1. In the stage of feeding strategy change, the methane molar and volumetric productivity were 351,9 molCH4.m-3 .d-1 and 7888 mLCH4.L-1 .d-1 , receptively, and the yield methane production per removal organic matter close to the theoretical value. The energy production were 25,1 MW and 30,3 MW in the batch and fed batch conditions, respectively. The kinetic model allowed known of AVOL and feeding strategy influence under the reactor performance to methane generation, analyzing the reaction coefficient of the compounds consume/production involved in the metabolic rote.
