摘要: This study investigated the effect of reduced pressure on biohydrogen production in an upflow anaerobic sludge blanket (UASB) reactor from whey permeate. The results showed that fermentation was more effective enhancing than dark fermentative hydrogen at atmospheric pressure. Mesophilic a constant hydraulic retention time (HRT) 24 h and increasing organic loading rates (OLRs) 20, 25, 30, 35 kg COD/m3 day. successfully operated all OLRs tested. maximum proportion biogas 47.7 %, volumetric rate (VHPR) 7.10 L H2/day yield 4.55 mol H2/kg COD removed occurred highest OLR. Increase OLR affected UASB exploited process able to remarkably improve performance high OLRs.
