However, efforts to convert this wastewater into biohydrogen are limited. Therefore, this research investigates the feasibility of converting palm oil mill effluent (POME) for biohydrogen production via dark fermentation. Temperature and hydraulic retention time (HRT) effects on biohydrogen production and COD removal efficiency in an up-flow anaerobic sludge fixed-film (UASFF) bioreactor were investigated. The experiment was carried out and analysed using a central composite design (CCD) and the Response Surface Methodology (RSM). The hydrogen (H2) yield, H2 production rate (HPR), and COD removal efficiency were investigated as responses. HPR increased significantly by 28.8 folds as temperature increased from 37 �C to 53.5 �C (transition from mesophilic to thermophilic) at HRT of 3 h. Meanwhile, the COD removal efficiency significantly increased from 24.76% to 33.33% between 4 to 9 h of HRT. Maximum H2 yield of 0.95 L H2 g?1 CODremoved, HPR of 10.39 L H2 d?1, and 35.9% COD removal were reported at the optimum HRT and temperature of 7 h and 57 �C, respectively. This study indicates that under the thermophilic condition and short HRT, POME could be treated while producing biohydrogen using the UASFF bioreactor. � 2022 The Author(s) Final 2023-05-29T09:36:14Z 2023-05-29T09:36:14Z 2022 Article 10.1016/j.eti.2022.102903 2-s2.0-85137805221 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85137805221&doi=10.1016%2fj.eti.2022.102903&partnerID=40&md5=bc7b62e178181beb65f03bc889d2207c https://irepository.uniten.edu.my/handle/123456789/26697 28 102903 All Open Access, Gold Elsevier B.V.
