Application of Immobilized Upflow Anaerobic Sludge Blanket Reactor Using Clostridium LS2 For Enhanced Biohydrogen Production and Treatment Efficiency of Palm Oil Mill Effluent

A novel polyethylene glycol (PEG) gel was fabricated and used as a carrier to immobilize Clostridium sp. LS2 for continuous hydrogen production in an upflow anaerobic sludge blanket (UASB) reactor. Palm oil mill effluent (POME) was used as the substrate carbon source. The optimal amount of PEG-immob...

LS2 for continuous hydrogen production in an upflow anaerobic sludge blanket (UASB) reactor. Palm oil mill effluent (POME) was used as the substrate carbon source.

The UASB reactor containing immobilized cells was operated at varying hydraulic retention times (HRT) that ranged from 24 to 6 h at 3.3 g chemical oxygen demand (COD)/L/h organic loading rate (OLR), or at OLRs that ranged from 1.6 to 6.6 at 12 h HRT. The best volumetric hydrogen production rate of 336 mL H2/L/h (or 15.0 mmol/L/h) with a hydrogen yield of 0.35 L H2/g CODremoved was obtained at a HRT of 12 h and an OLR of 5.0 g COD/L/h.
